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??

I would..........CFL's generate a lot less heat than incandescents.

Those original ratings were based on heat generation & dissipation.

I have several 1930's fixtures that we rated for 60 watt max, that
I've been running 100 watt CFL's in for about a year....no problem.

As an examples a 60w incandescent is too hot to unscrew & handle when
on.....a 100 watt CFL can easily be handle "hot".
