| Apr 22, 2015 at 18:26 | comment | added | Hank | ...sorry I thought you said "LED/CFL bulbs don't create heat". My comment isn't really relevant in light of what you actually said! | |
| Apr 22, 2015 at 18:22 | comment | added | Hank | All lamps have inefficiency and will produce heat. Incandescent, halogen, CFL, and LED bulbs convert 98%, 97%, 91%, 88% of their electric consumption into heat, respectively. An ideal (no heat) "60 watt" / 800 lumen bulb would consume only about 1 watt of electricity. | |
