Residential Lighting by the Numbers

The following is a re-print of an ALA Technology Newsletter that was written by Terry McGowan at the ALA. It contains some interesting facts about current lighting usage and future trends.

"Reliable data about the energy use of lighting products, together with numbers about the types and the quantity of products sold into the residential market, has become an increasingly important part of ALA activities in recent years. I pay particular attention to lighting energy data and the mix of light source products in various lighting applications.  Those numbers indicate market trends and information about the technology being used. Demographic numbers are a good predictor of market activity too. An example is the market for elderly-friendly lighting which is growing because every day more than 11,000 people reach 65 years of age in the U.S.

Starting in 2002, the U.S. Department of Energy began publishing detailed lighting inventory and energy consumption data by sector - residential, commercial, industrial and outdoor.   An update was published in 2012 based upon 2010 data, but last December, for the first time, residential lighting energy use was examined in detail.  

Report Results fromResidential Lighting End-Use Consumption Study: Estimation Framework and Initial Estimates

(Download at no charge, here: http://alturl.com/qgbh2)   

• In U.S. residences, the average daily use per bulb is 1.6 hours.
• The average bulb uses 47.7 watts. (That's down substantially from the 67 watt average reported in the 2002 report.)
• There are more than 67 bulbs in the average home considering all home types   (single family, multi-family, etc.); but single family homes average more than 85   bulbs/home. (The average reported in the 2002 report was 37 bulbs/home.)
• Household lighting energy use varies substantially by region but averages
• 1,700 kWh/home per year. New York and California use the least averaging
• Less than 1,500 kWh while states including Montana, Wyoming, Arizona and Missouri used the most averaging over 2,100 kWh per home annually.
• The cost of energy used for residential lighting also varies by region, but total home lighting energy costs range from $200-300 per year.
• Bulbs in bedrooms, bathrooms, living rooms and kitchens consume the most lighting energy in the average home.
• Dimmers control only 4% of the bulbs in the average home and almost 80% of those bulbs are in ceiling fixtures.
• Incandescent bulbs (2010 data) remain the most widely used light source in homes (They are in more than 62% of the sockets); but the use of CFLs and LED bulbs has increased with CFLs at slightly more than 20% of the socketson average (also 2010 data).

Since the 2010 data above didn't include the rapid growth in the use of LED bulbs during the past couple of years, I looked at another DOE report which uses the same database, but which analyzed the LED adoption rate over the 2010-2012 time period.   

Adoption of Light-Emitting Diodes in Common Lighting Applications.

(You can find that report at http://alturl.com/7z6yd)

• What the 2010-2012 report shows is that the conversion of residential sockets from standard incandescent to halogen incandescent, CFL or LED bulbs has rapidly increased over this last two-year period.  
• Some of that increase is due, of course, to the phase-out of standard incandescent bulbs; but lower prices for CFL and LED bulbs, better bulb performance, more product choice and market activities such as rebates and the entry of new manufacturers into the market have all played a role as well.  
• Of the "A-line" bulb sockets, 62% of the 3.2 billion in homes contained standard incandescent bulbs in 2010. That number has now dropped to 55%.
• But, LED bulbs, even though some 20 million have been installed over the last two years, still fill less than 1% of the total available sockets.  
• The next two years, however, will likely see a dramatic change in those numbers because of the phase-out of the standard 40 watt and 60 watt bulbs beginning on January 1, 2014. Those two bulb types represent almost 60% of the standard bulb market.

 The big question is: What will consumers put into those sockets as the conventional bulbs are replaced? The answer to that question will make 2014-15 an unusual and interesting time in the lighting business."

Why Is There A Fire Risk If I Use More Than The MAX Watts On My Light Bulb Socket Label?

Most lamps sold today have a label similar to the one pictured here.Why, might you ask, is there a fire risk if you use a higher watt light bulb than the one listed? The reason is because higher watts equates to higher temperatures. A watt is a unit of heat and is the amount of energy a light bulb uses. A watt is not to be confused with a lumen which is the measure of light output.

Lampshades confine a certain amount of heat depending on the diameter of the top opening. The smaller the opening, the smaller wattage light bulb should be used. Metal lampshades get hot themselves, sometimes too hot to touch. Sockets are made in lots of different quality levels and can get really hot also. The components of a light fixture all work together is a certain way. Whatever you do, pay attention to the label and use the proper incandescent light bulb.

All that being said however, CFL's do not generate much heat at all so you can use a higher wattage equivalent CFL to produce more lumens than a lower wattage incandescent light bulb. For example, a 13 watt CFL produces about the same amount of light as a 75 watt incandescent light bulb so you could use it in a fixture that limits the watts to 40. Just don't mess around with incandescent light bulbs, they can really be a fire hazard!

Lighting and Color - Why Color Rendering Index is Important

Now that regular incandescent light bulbs are a thing of the past and LED's and CFL's are the new "go to" light bulbs, what can you expect your house to look like? The reason I am asking this question is because the colors in your home are going to appear differently than they do under good, old fashioned incandescent lighting. This is because of something know as CRI or Color Rendering Index, a scale of 0-100 where incandescent light bulbs are at the top of scale, 100.

Different light source have different CRI's, all of which are compared to incandescent light bulbs, but non of which are equal to incandescent. Fluorescent and LED light sources vary in CRI between about 75 to about 85 with some LED's approaching 90. Therefore things are going to look different depending on the CRI of you light bulb. Note the picture of the fruit and vegetables above. For most purposes, a CRI of 85 is considered good enough in residential applications.

This chart lists different light sources and their associated CRI values. At the bottom of the list is Low Pressure Sodium, a light source that was primarily used in highway lighting in the past. With this kind of lighting, a police officer could not tell the difference between blood and oil at an accident scene. CRI does make a difference!

New light bulb labeling laws are useful in selecting the correct light bulb with a satisfactory CRI. Please see this label and note that in addition to other important information the CRI value is shown as "Color Accuracy".

Please be advised that higher CRI's require a higher standard of manufacturing. In a fluorescent light bulb more expensive phosphors must be used and in LED's higher quality computer chips must be used. Therefore you can expect to pay more for better quality light. There is no right or wrong, just be sure you understand the differences.

Sizing Light Fixtures

I am often asked about the proper size of a lighting fixture so when I saw this article in "Residential Lighting" magazine I decided to share it with you. Randall Whitehead is a regular contributor to the magazine. Helpful advice for calculating proportional decorative lighting based on a room's dimensions. By: Randall Whitehead, IALD Q: What is the rule of thumb for determining the size of a chandelier or pendant fixture for a given space? I have a 25-by-30-foot area over a stairwell and I don't want too large or too small a fixture. If you could help me out, it would make me very happy.  A: Just think of me as verbal Prozac. Try this formula: Add the dimensions of the width and length of the foyer area together. This number will be the measurement in inches what the width of your fixture should be. Based on the dimensions that you have given me, I think you should be looking at a chandelier that is 55 inches in diameter. The length will be a little bit harder to determine, as it depends on the ceiling height. Taller ceilings can take longer fixtures. Somebody in your family or your contractor could make a mock-up out of wooden dowels and strings to get a feel for what the fixture would look like in the space. Randall Whitehead, IALD, is a professional lighting designer and author. His books include "Residential Lighting, A Practical Guide."

LED Technology is Becoming Mainstream

The following story appeared in the Wall Street Journal on Saturday, September 28. I pass this along to you because it is an example of how LED technology is becoming more popular.

Where LED Leads, Design Will Follow

Smaller, cooler and increasingly programmable, LEDs are making possible some startling tricks of the light—from glowing wallpaper to hackable chandeliers

By 
• MICHAEL HSU

Piercingly bright yet implausibly small, light-emitting diodes—or LEDs, to use their somewhat catchier nickname—are having an outsize influence on interior design. These energy-efficient light sources, which require a fraction of the electricity of incandescent and even the much-loathed compact-fluorescent bulbs, aren't just giving stressed-out environmentalists reason for optimism. They're also freeing designers to reinvent lamps—and light itself—in ways that once seemed impossible.

"It's similar to what happened in the '80s, when halogen arrived: Everything became smaller," said Piero Gandini, chairman of Flos, a design-driven lighting company. But Mr. Gandini predicts that the impact of the LED will be more dramatic: "Design will be less and less about the fixture itself and more about the immaterial aspect of lighting."

Here are five talking points about this game-changing light source that you'll want to memorize in case you attend a cocktail party entirely populated by futurists, or just want to know how LEDs are going to affect your living room, your kitchen and the way you read yourself to sleep.

The incredible shrinking light bulb

LEDs are tiny and thin—often about the width of a pencil eraser—which is letting designers give all sorts of light fixtures a nip and tuck. Take, for example, the old-school banker's lamp, typically a rather hulking presence. By replacing the standard bulb with a slender strip of warm white LEDs, Ron Gilad created a sleeker version, his Goldman lamp for Flos. Given the petiteness of LEDs, he was able to replace the traditionally bulky shade with a sliver of injection-molded plastic and considerably whittle down the brass base, since it no longer needs to support a hefty top. His lamp reads like a suit tailored for a particularly slim banker. "If we were using an incandescent bulb, we would not be able to reach the same level of minimalism," said Mr. Gilad.

Coolness under pressure

Unlike traditional light sources, the surface of an LED is cool to the touch, which means you can tuck them into tight spaces without heating up surrounding surfaces. In-the-know kitchen designers, for instance, are mounting strips of LEDs under upper cabinets to illuminate the countertop without inadvertently slow-roasting any food stashed inside cupboards. Architect David Rockwell installs LED fixtures directly into the perimeters of floors to uplight walls. While scorching incandescent lamps can discolor surrounding materials, like drywall and wallpaper, he explained, "with LEDs, you don't have the heat issues."

The coolness factor is also contributing to the continuing slenderization of lamps. The shade of Flos's Goldman, for example, sits very close to the light source, mainly because it can. And while Isamu Noguchi's circa-1950s paper lanterns—voluminous, semirigid globes—were designed to keep the paper far away from the incandescent bulb, the soft shade of their intricately folded descendant, Issey Miyake's new LED-equipped Mendori, can be stretched or compressed like an accordion, coming into proximity to the bulb with little risk of combustion.

Power in a snap

LEDs' energy efficiency may please the eco-conscious and the environmental regulators, but the lights' meager appetite for electricity also offers a distinct aesthetic advantage: It allows wires to be thinner and less thickly insulated. With certain LED chandeliers, the power cord is indistinguishable from the thin cables suspending the fixture from the ceiling. The word "floating" is frequently invoked.

This characteristic is also letting designers embed LEDs in paper-thin materials, creating wallpaper, for instance, that's studded with dim points of light. In such cases, the "wires" have been reduced to a very thin conductive material. To create its Abyss wallpaper collection, released this month, London-based Meystyle applies the material by hand; Ingo Maurer's LED Wallpaper goes a step further: A conductive ink is printed directly on the paper.

The ease of powering LEDs also allows designers to "daisy chain" lights—kind of like attaching one string of Christmas tree lights to another. Luceplan took advantage of this when creating its Synapse system, a module-based approach to room dividers. Each star-shaped piece, illuminated by a color-adjustable LED, snaps together with the next, providing electricity to the others connected to it. The result: a glowing web of stars that can subtly divide a living room from a dining room.

Chameleonic color

Perhaps the most powerful new tool that LEDs offer lighting designers is the ability to adjust the color temperature of white light. A controllable feature known as "dynamic white" offers almost as many minute variations on paleness as Benjamin Moore does with paint.

Dynamic white fixtures contain arrangements of warm and cool white LEDs, and achieve their effects by delivering different blends of the respective light, explained lighting designer Linnaea Tillett, who has illuminated spaces created by architects including Maya Lin and Diller Scofidio + Renfro. "It's amazing how much subtlety and finesse they provide," said Ms. Tillett. "You can change the whole emotional tone of a room using the same light fixture."

For one client with a windowless room, Ms. Tillett set a dynamic white LED on a timer to cast a pure, sunlight-like glow early in the day that gradually became more golden in the afternoon. "Particularly in windowless rooms, it allows you to create a sense of the passage of time," she said.

Although this feature is primarily available in products aimed at architects and interior designers, it is trickling down to the consumer level. Luceplan's Curl lamp, for example, has a phosphorous lens that lets you shift the color temperature of the 8-watt lamp from a warm 2400K to a cooler 3500K by twisting a dial.

The hackable light

LEDs are essentially light-producing semiconductors—which means it's increasingly easy to build "smart" features directly into the light source itself. "With LED, we are moving from electrics to electronics," said Mr. Gandini of Flos. He predicts that lamps will eventually be able to interact with their surroundings, perhaps by tuning their color temperature and brightness levels to settings triggered by the presence of an individual's smartphone. (Some of his company's lamps already have built-in occupancy sensors, as well as sensors that adjust the intensity of a beam depending on the ambient light levels in a room.)

Innovation is accelerating. "In the past, there were only three or four good suppliers of traditional light sources in the world," said Mr. Gandini. But because of LEDs' overlap with the semiconductor industry, he added, a wide range of electronics companies, especially in Asia, are now manufacturing them—and each is contributing its own ideas on how light and electronics can be integrated.

On a smaller scale, the open-source movement is letting independent designers deliver advanced features that previously would have required an engineering team to execute. The Dim(some) Phonezone chandelier, by Brooklyn-based designer Brendan Keim, incorporates eight LEDs that can be controlled individually with a smartphone app—a trick Mr. Keim was able to pull off using an open-source electronics platform called Arduino. "It's very accessible for artists and designers to jump into," he said. "Anyone who is familiar with Arduino could hack this lamp. You could make the LEDs twinkle or fade light from one side to another."

The technological potential of LEDs is only beginning to be realized. "It's about the evolution of software and control gear," said Mr. Gandini, "but also our cultural imagination."

Things to Consider When Buying Exterior Lighting Fixtures

Your outdoor lighting fixtures are one of the first thing people notice when they look at your house. The fixtures set the tone and say a lot about the home owners. There are many, many different types, styles, sizes and quality levels of exterior lights so you should learn some of the basics before buying.

Hubbardton Forge Exterior Fixture
(I have several of these on my house)

 Size - This is an important consideration that many buyers overlook in their purchasing decision. A fixture on display in a lighting store may look large in the store but when mounted on the side of a house may look really too small. So before buying a fixture I recommend that you make a model of the fixture by cutting out a piece of paper or cardboard the size of the fixture and pinning it to your house. Then go down the driveway to the street and look at your house from a distance. How does the fixture look? Too big, too small or just right?

Glare - My biggest gripe with most exterior lighting is the amount of glare it produces. A prime example are the flood lights that many people mount to the garage that come on when somebody drives into the yard. How does that help you see anything! The glare of the lights blinds you so you can not see anything until your pupils dilate again. You do not need much light outside when it is dark; it is the contrast produced by a little light that helps you see, think of the moon. (Also, the neighbors might not like the light pollution produced by glarey exterior fixtures). So I recommend you buy fixtures that do not produce glare and use frosted light bulbs.

Quality - There is no question that good quality is more expensive than poor quality, but good quality is

Dark Sky Fixture

usually a better value and it shows! If you plan to live in your house for a while buy a better fixture once rather than a cheap fixture twice or three times, especially if you live in a harsh climate, like almost everywhere. Salt air, ice, wind, excessive sun and heat are all tough on an exterior fixture. Better quality is usually noticeable also. 

Dark Sky - These fixtures are being mandated in a lot of communities for good reason, they contain the light and prevent it from spilling over and causing light pollution. This is especially important in sensitive areas where the night sky is still visible. They provide security and safety and do not allow light to escape into the night sky. I am a big advocate for dark sky fixtures for lots of reasons, no light pollution and no glare to name two.

Style - Style is purely a matter of personal taste. Styles range from Colonial America to Mission to Ultra Modern and everything in between. Chose what you feel looks good on your house. It is your house after all. There are all sorts of different finishes available too. So, for example, you can see the same fixture in a dark brass, raw copper, antique brass, green verdigris, raw brass or mission brown finish. They all might look great, but pick the one that you think will look best on your house.

Exterior lighting is important for safety and security, and it also enhances the appearance of you house. Visit an independent lighting showroom for the best quality and design options.

Lighting Makes All the Difference When Buying Clothing!

How many times have you used a dressing room in a clothing store to try on a garment before making a purchase? Lots of times, right. How many times have you gone into the dressing room and said to yourself: "Wow, this dress really looks great."? Chances are that when you were "wowed" it is because the lighting was great - the lighting fixtures were placed appropriately, the color temperature of the light bulbs was flattering, and the color rendering index of the light bulbs was close to 100.

Well Lighted, Comfortable Retail
Dressing Room

It is amazing what a difference lighting makes in how you look! Great lighting makes you look like a million bucks. Poor lighting washes out your complexion, distorts the color of your clothing and adds unflattering shadows on your face.

Why then would a retail establishment, trying to sell clothing, not invest what it takes to make their dressing rooms the best they can be?

To quote from an April 6, 2011 article from the Wall Street Journal entitled "Why Are Fitting Rooms So Awful": "Lighting is a critical component. "Any woman who goes into a fitting room that has really bad lighting, you look at yourself, you look at your skin and you're completely distracted," says Anthropologie's Ms. McDevitt. "Then you lose the real reason why you were in there."

The new Ann Taylor rooms have six sources of lighting and three types of bulbs, compared to one source and type of lighting in the old design. The mixture of ceramic metal halide, compact fluorescent and low-voltage bulbs is more flattering, Ms. Dorfman says.

Bloomingdale's has installed rear-lit three-way mirrors, which allow customers to see themselves from a variety of angles. There is also a ceiling-mounted light three feet back from the mirror to eliminate shadows on the shopper's face, says Jack Hruska, executive vice president of creative services at Bloomingdale's."

What to Look For in a Ceiling Fan

When buying a ceiling fan there are several factors that should be examined before making a purchase. A ceiling fan is basically a motor with blades suspended from a ceiling. Pretty straightforward yet there are huge quality differences that can impact you and the comfort of your home.

Die Cast Motor

Putting aside all style considerations, motor size, AC or DC motor, blade pitch, blade arms and mounting hardware are the factors you should familiarize yourself with before buying a fan because these are the factors that determine the airflow, measured as CFM, the efficiency and the quiet operation of a ceiling fan.

Motor size is measured in millimeters. A small motor might be 144 x 10mn whereas a large motor might be 188 x 22mn. Blade pitch should be at least 14 degrees. Blade arms should be sturdy metal, strong enough to accommodate the blades. A DC motor is more efficient that an AC motor, but it is more expensive to purchase initially. Look carefully at all the specifications before making a purchase. You will have the fan running most of the time so you will want it to be quiet and capable of moving air.

Three Essential Types of Lighting

Three essential types of lighting are Ambient, Task and Accent, sometimes called the triple crown of interior illumination.

Good Source of Ambient Light

Ambient Lighting, also called general or overall lighting, provides the light necessary for safe and effective interior illumination, allowing hazard-free navigation of the interior space with minimal shadows. Usually a ceiling fixture meets the requirements of good ambient lighting. To determine a room's ambient lighting requirement multiply the room's square footage by 1.5 to get the minimum number of incandescent watts necessary. You can then translate those watts into fluorescent or LED wattage equivalents if you like. Ambient is only the base layer in a well designed lighting plan which also could include wall sconces, floor lamps, recessed lights or picture lights.

Task lighting focuses light on tasks that are performed in a given room. It is a layer of light that should be used in addition to, not in place of, ambient and accent lighting. In most homes, kitchens, laundries and bathrooms require the most task lighting. But the requirement of these three room require different types of task lighting. Kitchens need recessed lighting in the ceiling aligned with the front edge of the lower cabinets in addition to under cabinet lighting and some kind of ceiling fixture and/or pendants. Bathrooms need wall sconces on either side of vanities for optimal light for makeup application and shaving. And laundries need bright ambient light to facilitate separating colors and to provide light for ironing and folding.

Example of Accent Lighting

Accent lighting is used to light art, sculpture or interesting architectural features like stone fireplaces. It is the layer of light that gives a room "texture" and interest and dimension. It lets you focus on the interesting features that are in the room. Some people think that accent light should be up to three times brighter than surrounding ambient light. I do not necessarily agree with this thought. I think accent light should not distract, but rather enhance, the ambiance of the room. Wall sconces, picture lights and directional recessed lights can all be used as accent lighting.

And remember, use dimmers on every light in the house. They cost a little more than switches, but they allow so much greater control over the lighting that they can really make a lighting plan "pop".

Lighting and the Visual Environment for Senior Living.

Generally, the visual requirements for senior citizens are different than for the younger generation because of changes in the eye and in the visual nervous system. With age, the pupil becomes smaller thus reducing the amount of light that can enter the eye, the lens becomes yellowed thereby scattering light, reducing contrast and reducing the ability to focus, and ocular disease is more prevalent in older people. All these factors contribute to the special lighting needs of the senior population.

Great Lighting for Older Eyes!

 To quote the IES publication "Lighting and the Visual Environment for Senior Living", "In a study conducted by Sorensen and Brunnstrom in private homes in Sweden, a direct correlation was discovered between "good" illumination in an older person's residence and that person's quality of life. The study defined good illumination as: a sufficient quantity of light, appropriate direction of the light, good contrast, and light that does not cause glare. Physical condition, appetite, general good health, and self-confidence improved with good quality lighting. In addition loneliness, anxiety, and temper were diminished."

Bad Senior Lighting - Glare, Poor Contrast and
 Bad Direction of Light.

To go on quoting from the same article, "Poor lighting is associated with falls among the elderly. Investment in proper lighting is an excellent means of reducing health care costs and maintaining an independent life style...Good lighting should be viewed as prevention, and must receive priority attention by all retirement complexes, long-term care facilities, seniors living at home, and the community at large. Optimum light exposure ought to be as uncontroversial an aim of future health policy as best possible nutrition."

Unfortunately, in my limited experience with two elderly parents and a parent-in-law, lighting in elderly residences is far from "optimal". It was more like the photo on the right with lots of glare and poor contrast. Shiny floors and overhead bright recessed lights cause glare both from above and from the reflection of the light on the floor. Hospitals are the same way. And unfortunately the lighting in most homes is installed by the electrician or contractor without regard to proper lighting techniques (for any age group). A well lighted space will be a well lighted space for any age...it is timeless. Plan ahead when lighting your new home or renovation. A good lighting plan will pay you dividends forever.

Labor Day Weekend - You Know What That Means!

Well Labor Day Weekend is here already. Wow, summer did not last very long (unless you are a Mom with young school aged kids). Next comes fall, a great time of year for the lighting business because as it gets dark earlier and earlier, people discover that they need more lights. My advice, beat the crowds, buy your lights now. Be prepared!

Great Lighting Solution!

A floor lamp like the one pictured here is a great solution for a dark corner. This lamp has a center socket that will take a 50/100/150 3-way light bulb plus three sockets, on small arms around the central socket, that each take 60 watt light bulbs. That is a lot of light. Enough light for reading, sewing or playing card games. And, a light like this is an economical solution, costing only a couple of hundred dollars.


This time of year also means back-to-school. And back-to-school means homework. Students need good lighting for their homework which means a desk lamp like the one pictured on the right.

What Do I Think About LED?

I get asked this question almost every day, and every day I have the same answer: "Don't get locked into a technology that is changing daily." By this I mean, use LED replacement light bulbs, but do not buy fixtures with dedicated LED modules already built in. The LED dedicated fixtures are much more expensive than conventional fixtures, and you will be stuck with them when a much more advanced LED option becomes available in a few months or a year. The exception to this rule is in the use of under cabinet or cove lighting where LED tape light and other LED fixtures have been proven to be good alternatives (albeit more expensive).

The Light bulb pictured here on the left is a technological breakthrough. This light bulb is manufactured by Soraa, the most advanced LED MR16 manufacturer in the world. This MR16 can be used in any fixture that uses MR16's. It is dimmable, comes in various color temperatures and is available with a variety of lenses, filters and louvers which control beam spread and glare. Not all replacement bulbs are created equal. This is one of the best. It costs a little more than it's cheaper rivals, but the results are noticeable.

The light bulb pictured on the right is an LED replacement bulb for a standard incandescent light bulb. Notice the "fingers" that extend up from the socket to the base of the globe. These "fingers" are made from a material that will draw heat away from the solid state components in the light bulb. (LED's generate heat because of the resistance in the solid state components - much like a computer).

This brings me to crux of the LED dilemma - until scientists can find much more efficient heat sink materials than are available today, LED's are stuck in limbo. The greater the lumen output, the more heat is generated and this heat must be dissipated. This breakthrough will come fairly soon, and when it does, there will be a flood of new products.

Trouble Falling Asleep at Night?

Do you or your kids have trouble falling asleep at night? It could be that you need less exposure to cool blue light, like the predominate light given off by TV's and computer screens, and more exposure to warm red light, like incandescent light bulbs or evening sunsets. This is because blue light interferes with melatonin production and red light encourages melatonin production. Melatonin is a hormone that helps regulate the sleep-wake cycle by chemically causing drowsiness and lowering body temperature.

Night, Night

Circadian rhythms are tied to sunrise and sunset and have controlled the rhythm of life ever since life began on the planet. Before electricity, humans went to bed when it got dark and woke up when it became light again. The predominate light in the evening for those generations was either natural sunlight or the predominately red light of a fire or torch. Therefore we have evolved to want to sleep when the sun goes down.

Lighting Your Kitchen - A Focal Point in Today's Home

While cooking and cleaning functions endure, kitchens are hubs of activity in homes today. I know that when we entertain guests at our house we cannot get them out of the kitchen. We entertain, eat, prepare food, wash dishes and even read in our kitchens. That is why kitchens require several layers of light to serve all the needs of the modern home.

Lots of Layers of Light

  Please note the different layers of light in this kitchen. There are pendants over the island, recessed lights over the counters, under cabinet lights (also lighting the counters), range hood lights, picture lights, a chandelier over the kitchen table and even a table lamp! That is seven layers of light! And how good does it look, and how pleasurable it would be to entertain in this space. Cooking would even be more enjoyable. (Of course I love to cook so I would love having a kitchen like this).

You do not need to have a magnificent home to have good lighting in your kitchen. If you choose correct lighting for your space it will look great and allow you to perform all the kitchen tasks. Really good recessed lights are quite affordable and should be used over the counter tops, not behind them. Island counters require good lighting. Multiply the square footage of the counter top by 2.5 to determine how many watts of incandescent light is needed. Then select fixtures (usually pendants) that can deliver that amount of light, or augment those fixtures with additional recessed lights spaced between the fixtures. Most families spend a lot of time the their kitchens so make it a priority to light your kitchen well.

"THE FUTURE IS (ALMOST) NOW: IS THE LED LIGHT MAINSTREAM?"

I have borrowed some quotes from the above mentioned article that appeared in "enLIGHTenment" magazine's July, 2013 issue written by Ted Konnerth, CEO of Egret Consulting Group. A lot of this article is technical so I have selected passages that pertain to consumers.

"Given the recent attention our industry has paid to solid-state lighting, I am sure it is hard for you to believe that fluorescent, high intensity discharge (HID), and incandescent products still represent 85 percent of all lighting sales. I’ve attended and led innumerable discussions at industry gatherings on the emergence of LED. And from what we’ve heard, the future is now. However, new technologies always take time to gain full acceptance. The legacy lighting manufacturers have millions of capital dollars invested in tooling, machinery, and processes that limit their ability to make wholesale changes to their companies. The new entrants have no embedded capital limitations, but they don’t have the channel relationships to push LED adoption at a greater pace. And, their limitation of lighting expertise limits the ability to match LED’s benefits with lighting application expertise.

According to a Department of Energy Report from last year, LED lighting will reach a predicted market share of 74 percent by 2030. I believe the rate of adoption will be far faster than that; but the limiting factor will be centered on design." (My emphasis).

"Lighting Will Look & Feel Different

To move the industry forward, it’s imperative to have a robust exchange of ideas between fixture designers and lighting designers. Given that lighting will interface within the overall electronic control systems of buildings, the migration of lighting and all things information-based will be crucial. The benefits of LED are proven, so now the discussion has to move to the proper application of LED as a light source and designing lighting systems that incorporate proper lighting into an overall efficient design. LED has created so much discussion that we have largely lost the emphasis on “lighting.”

"Proper lighting involves so much more than brightness. Glare, comfort, uniformity, color rendering, accent, layering, and “feel” are the fundamentals of quality lighting." (My emphasis).

"The design community needs to take over the discussion of LED from this point forward. The current efficiency and brightness of LED is sufficient for meeting lighting needs in most applications now. Future efficiencies will contribute additional cost reductions and system modifications; but “brightness” needs to disappear from our vernacular. The day of a 300 lumen/watt emitter is within feasibility; but that doesn’t mean that we will require that level of power for all applications. Technological improvements in efficiency should be encouraged, but we have the lumen packages to create amazing lighting designs today; let’s get back to being a lighting industry again."

"A careful blend of old and new ideas is needed to accelerate the lighting renaissance.

There is no doubt SSL will change the future of the lighting world and, in turn, how our entire world is lit. Unfortunately, many individuals and companies within the lighting industry will not survive the change. They will be too slow to adapt and will simply lose their relevance and/or market share. But those who do survive the change – and especially those who move it forward on the design side – will reap the rewards. It is truly an exciting time to be alive and active in the lighting industry." 

Mr. Konnerth certainly has gotten it right. LED is here, but the fixtures needed to make LED feasible for most applications are still evolving...somewhat slowly it seems. The knowledgeable consumer is a wise consumer.

The Truth About Lighting Allowances in Contractor's Proposals.

I went to an open forum Q & A at a contractors office yesterday. This is one of the best contractors in the State. They build great houses, expensive houses in beautiful coastal locations, and they have an outstanding reputation. There were lots of sub-contractors and a few vendors, like myself, there. Nobody in attendance has ever experienced such a meeting, a meeting called to solicit feedback from subs and suppliers about how to make the building process better for the client. It was a "team" building experience and I was happy to be part of the "team".

Typical Contract

 I raised my hand and expressed my primary concern which has to do with the lighting allowance in most contracts. Whereas the framer, the roofer, the concrete company and the carpenter are all given blueprints and asked to quote their prices, I come to the party much later and have never had a chance to estimate what the lighting will cost. In fact, I could never provide that estimate without meeting with the client to choose specific fixtures. Prices of lighting fixtures vary greatly for lots of good reasons. The lighting allowance is therefore necessarily a "plug-in" amount.

When I said that there was no way someone building a $2,000,000 house with a lighting allowance of $5,000 (exaggeration) could possibly light that house for $5,000 they told me the truth about lighting allowances (and other allowances too).

The Truth About Lighting Allowances is contractors bid against several other contractors for every job, and if they included the REAL cost of lighting they would never get the job because the other contractors always "low ball" the allowance. The allowance is a "garbage figure", to quote the contractor. I totally understand this thinking and I respect them for being truthful with me, but when I meet the client and tell them the real cost of lighting, there is sticker shock and disappointment. Most of the time the client tells me: "I went way over budget on my tile and I do not have any money left". I feel their pain, I really do, but without decent lighting they will not be able to see the tile that cost so much.

Anyway, I feel exonerated. I have been telling you that the lighting allowance is NEVER adequate. Now you know why. Be aware and be prepared. Please visit us at www.fogglighting.com and like us on Facebook. Remember I am always available to design the lighting for you.

A Ceiling Fan For Every Room!

Ceiling Fans are Cool! Ceiling Fans are Hot! Right on both counts. Ceiling fans help you feel cool during the warm months and help warm a house during the cool months. By so doing they can save up to 20% of the cost of both heating and cooling. They do not actually cool the house, but they make you feel cool because they move air over your skin which increases the evaporation of the moisture on your skin. And they do not actually heat your house, but they recirculate the warm air that otherwise would be trapped near the ceiling. So in the summer you can turn your thermostat to a higher setting and in the winter the warm air being recirculated keeps the lower part of the room warmer lessening the call for the furnace to come on.

Cool Fan!

Ceiling fans come with different size blades so you will want to select the correct size fan for the size of your room. A 36" fan is appropriate for small rooms up to 75 square feet. A 42"-50" fan works well in rooms between 76-144 square feet. Rooms that are 144-255 square feet are right for 52"-54" fans. A large room that is 225-400 square feet should use a 54"-72" diameter fan and it is appropriate to use multiple fans in a great room that is larger than 400 square feet.

Ceiling fans are available with lights or "light kits" so they can be used to add light to a room. Contrary to popular opinion, the lights do not have to be ugly, even though a lot of them are really, really ugly. Those ugly fan lights have given all fan lights a bad reputation. Some ceiling fans have full function remote controls thereby enabling you to reverse the direction of the fan, change the speed of the fan and turn the lights on or off from the comfort of your Lazy Boy. Some fans have a reversing switch on the body of the fan and others cannot be reversed at all.

There are many, many ceiling fans available today in all kinds of styles, sizes and colors. Be sure to choose a good quality fan with a strong motor and blades that are at least a 14 pitch. Please visit us at http://www.fogglighting.com and like us on Face Book.
