It seems to me that if a bulb uses less energy, then LESS heat would be generated. Heat has to come from somewhere, after all.

I used fluorescent bulbs for fixtures under which I grow African violets, and while they don't stay "cool," they're definitely no warmer than an incandscent bulb giving out the same amount of light. However, if there's any sort of caution that on the packaging, that of course, is your best guide.

Yes, as long as the energy saver fit inside the light cover. The florescent bulbs do not get hot. The biggest problem with these bulb is they are too big. So, if u want to use the energy efficient bulbs, get the type (smaller size ones).

This is a total fabrication, compact fluorescent burn alot cooler then regular lamps, thus the energy savings while using them. Tou can use them in place of any regular lamps.
