Say you've got an old circa 1954 ceiling light fixture. Spec'd for 2
max 40 watt incandescent bulbs.

My Sylvania 100w-output CFL's take 23w input.

100% safe to use 2 of these CFLs instead of 2 40w incandescents??

Let's see... 40 + 40 = 80
and... 23 + 23 = 46

Okay... 46 80

No problem, and you'll have a lot more light in the area to boot.

I replace all my 100W incandescents with 40W CFLs, which are "150W
equivalent" to incandescent. The rooms are way brighter, with a nice
white light instead of a sickly yellow, and I'm still using less than
half the energy that I was before.

Put three 23W CFLs in the overhead fixture in the kitchen. It's like
full sunlight in there now.
