Yeah, I basically agree with that statement. There does seem to be a lot of confusion about LED's and heat. As ShanghaiDan mentions, it boils down to watts. The good news is this...both CFL's and LED's can produce lumens using less watts than incandescent bulbs. For example (in ballpark figures), to produce 800 lumens would require a 60 watt incandescent bulb. The CFL would take only a 13-15 watt bulb. And, an LED bulb would take only a 6-8 watt bulb. See why LED's are becoming more popular? As LED technology continues to evolve, we are seeing better color temp choices and efficacy exceeding 100 lumens/watt. From what I'm hearing, the next technological advance in automotive headlights is laser (check out Audi and BMW). How cool will that be?
