Residential Lighting By The Numbers
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.

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.

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.
What are you going to put in your sockets? That’s the question that you have to answer for yourself. Please visit us at www.fogglighting.com and like us on Face Book. Be sure to download the UL app, LightSmart, for all kinds of interesting lighting information.
