“CFLs are pretty cheap.”
And the light they produce is harmful to your eyes. And I really like the mandate for “the first light in your bathroom has to be CFL” here in CA. Get up to use the bathroom in the middle of the night and you have to wait for a minute for the bulb to generate enough light for you to see the toilet. Good news is that the canned lights I had to put in in a recent remodel can accommodate the “guts” from a similar fixture that uses incandescent bulbs. Just pissed me off to have to buy two fixtures to pass inspection.
Well that is stupid. Bathroom lights are ones that should be turned on only while you're in the room, need to be quick to turn on and should be on a dimmer (shaving light is different from the "hit the target at 3 AM" light). Thus the bathroom is the absolute worst room for CFLs.
