Please be sure to think about floor lamps as you consider how to add light to your rooms. Floor lamps add interesting design elements and provide a pleasing layer of light.
In living rooms and family rooms you do not need a specific amount of illumination to perform tasks, you need layers of light to add interest and make the room feel inviting for friends and family.There are thousands of different styles of floor lamps from which to chose, something for every taste and situation.

Technical Explanation: The CRI is a unit that measures the ability of a light source to reproduce the colors of objects faithfully in comparison with an ideal source of light, or natural sources such as sunlight. The CRI is a determined value from 0 to 100, with 100 being the value “perfect” or daylight.
Real World Explanation: The CRI determines how you and your surroundings appear to you and the other people in your environment.
Here is an example of what is happening in the the world of lighting today and what will continue to happen in the foreseeable future. LED’s are all the rage and designers are finding all sorts of new ways to incorporate them into light fixtures. The reasons are clear: LED’s consume far less energy than incandescent light bulbs, LED’s are cool to the touch, LED’s have better color temperature than they did in the past, LED’s have a super long life, and LED’s are small so fixture design can be very creative. In addition to LED fixtures like this one, LED light bulb design is evolving very quickly also. Technicians are finding ways to make them more attractive and more like the good old fashioned incandescent light bulbs. Some of the new LED light bulbs even grow warmer in color temperature as they are dimmed, just like incandescent light bulbs do. Additionally, new, more efficient heat sink materials are being developed which allow LED light bulbs be more streamlined and closer in appearance to both A-lamps and candelabra bulbs. Pretty soon you will be able to use LED bulbs in chandeliers and not notice a difference between them and the candelabra bulbs they replace. Best of all, LED’s are becoming less expensive all the time as manufacturing becomes more efficient and more manufacturers enter the marketplace. As with anything though, I urge you to be careful when buying any LED product as there still are huge quality differences among the myriad of products and producers out there. Try to see the product before you buy it to make sure the color of the light is acceptable to you. I recommend buying dimmable LED light bulbs and fixtures – some LED’s are not dimmable. I also recommend caution in using dedicated LED recessed lighting fixtures. Once you install them they are in the ceiling a long time and the quality of the light might not be satisfactory for you. Instead, consider buying a regular recessed fixture and using an LED light bulb. That way you are not locked in. Please visit our website www.fogglighting.com and like us on Facebook.

Residential Lighting: Tell us how light levels affect circadian rhythms. (more…)
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.
- 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).
- 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.
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!

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.

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.
