I've used ceramic heat emmiters, hated them. They make the place bone dry, and can't be used for viewing purposes.

I personally don't "provide" a night time drop. My heat sources run 24/7 and are perfect. I use red bulbs which supposedly reptiles can barely see, but I can. I like to see my herps at night, pitch dark is no good. The heat drop is provided by the drop in temp at my house. It provides it perfectly. So just buy some red bulbs and run them and a heat pad. And use a florescent light. Hehe, I love it that way.
