I wouldn't think any trouble. The old incandescents put out a lot more heat
than the CF. Heat dissipation was the major concern, as I understand it. Use
the 23 watters, and don't give it a second though. Well, if the 23 watters
will fit. Many bulbs won't fit in the older incandescent devices.

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??

Thx,
