incandescent to cfl - heat conversion

komi(z7/8 DC)December 10, 2007

Hi all,

Is there a way to make a logical determination as to how bright a cfl can be substituted for an incandescent bulb?

My main concern is how much heat is created and whether the shade/reflector/wiring etc will stand it.

For example, I have an exo terra hood for a viv. It says max 26W incandescent. A "100W" CFL is 23W. Safe to use or no?

Clearly I've forgotten my basic physics, as this strikes me as a question that should be easily answered.

Right now I'm thinking of running the lights for 14 hrs but with 1 or 2 breaks during the day to prevent the air in the case from getting too hot. (This would also let the light fixture cool off a bit.)

safe. The heat produced is the number of watts. The light produced is the Lumens/watt. Irrespective of the type of lighting, the eventual product is heat, as only a tiny amount of the light energy is actually captures as plant sugars. Paul Mozarowski.

So 23W is 23W. Simple. Thanks!

So now that lamp that was barely bright enough at 26W (incadescent) is a real searchlight at 26W (CFL) :)
