CFL in humidity dome?

Hey guys, so this is my first real solo growing, so i have some dumb questions. If I have a humidity container (aprox 12"x12"x24"). I was going to germ some seeds in there, using one or two CFL;s (says "23w=100w"). Now there are two holes that you can open and close to change the humidity, and i was wondering if it would be a good idea to drop the cfl into the chamber, as it drops down about halfway, which would only leave a couple inches between the light and the rockwool. Not a good idea, or what? I am trying to use cfl's instead of my 400w to save e-. It also is the easiest place to attach the lights, by dropping them inside. Thanks guys.

Would it help if i added a picture?

I personally wouldn't try it (too much heat)

the alternative would be to put two lights just above the dome, but then it would have to be like 2-3 inches from the dome due to heat, and then it's like over a foot away from the plant, and they're only small CFL's, so i'm a little confused as to what is the best method.
