[Elecraft] LED bulbs

[Mike Reublin NF4L]

Well, yeah. But that heat does cost something. I'm not in the least worried, I'm just curious if it's factored into the advertised savings.

The LED bulbs I have -- 90 in all --- generate far less heat then the CFL's I replaced them with.  I can at least grab the base of the LED's after they have been on for a while and not get burned.  I can't say that for about 80 percent of the CFL's and in order to change an incandescent that's been on I either had to use gloves or wait 5 minutes or so until it and the fixture cooled off.
