Sue,

It's mostly the heat. I just had to rewire a hangling light fixture becuase the wiring had failed due to the heat baking the insulation off. And that was from using the recommended lamps. You can use a CFL at a higher light output and have less heat. I'm sure some of the pro's on the board can give you a better explanation.
