Look at Lighting: LEDs – Pricing No Longer an Excuse by Stan Walerczyk

In the last year, LED performance and pricing have really improved. I have been presenting seminars comparing LEDs with high performance incumbent technologies since the 2011 Lightfair. With the evolution of LEDs, particularly in the last two years, I had to change about 20% of the slides every few months. For example, in mid 2013 LED troffer kits may have not have been that cost effective, but by late 2013, they were. Early this year, I changed the title from ‘LED vs. Everything Else’ to ‘Becoming an LED World, But,’ because LEDs are taking over, but have not completely won yet. 6/13
