A Big Improvement For LEDs Coming

April 24, 2013 | Leave a Comment

LEDs have a mysterious drop in the light produced called “droop” when a higher current is applied.  That limits the amount of lumens an LED can make thus holding the technology down as a viable replacement for incandescent bulbs for all-purpose commercial and residential lighting. The situation could change now that the cause of LED [...]

The Lowest Cost Light Bulb

September 6, 2012 | 4 Comments

Overall cost for a light bulb is a consumer’s goal for environmentalists to hard-nosed green eyeshade number crunchers.  Today’s light-emitting diode light bulbs have a slight environmental edge over compact fluorescent lamps and that edge means money to you and me. The U.S. Department of Energy’s Pacific Northwest National Laboratory (PNNL) and UK-based N14 Energy [...]

More Light for More Work Will Get More Efficient

August 7, 2012 | 1 Comment

Two researchers at Sandia National Lab suggest their research shows, historically, that improvements in lighting from candles to gas lamps to electric bulbs have led to increased light consumption rather than lower overall energy use. Back in 2010 Jeff Tsao at Sandia and Harry Saunders of The Breakthrough Institute in Oakland, Calif., authored an article [...]
