We have all CFLs through the house. Excluding the garage (4 150W equiv)
and basement (14 4' fluorescent tubes) , Out of 17, I've only had 2
fail in the last 2.5 to 3 years. I only have a single sub mounted CFL
(in a can) over the shop entrance.. It's been on pretty much 24 X 7 X
365 for a good 3 to 4 years. The main lights in the shop are 22 full
spectrum 75 Watt, 8' tubes and the electric use shows I spend a lot of
time out here <:-)) .
None of the CFLs or tubes can be heard, AM broadcast through 440.
The "turn out the lights every time you leave the room" is a guarantee
of a short life for a CFL, so the Many off/on cycles of a bathroom light
would mean a short life although the newer ones are lasting longer.
LEDs are "expensive", but last a long time and use little power and
"they should" get much cheaper over the next few years as production
