I'd use a ceramic heat emitter with it. If you want to provide UVB then get a simple hardware store clamp lamp. Here's a link to one:

Emitters emit no light so are good to use at night and during the day. Frogs and other herps can still see the light from red bulbs, just not the color. Emitters get HOT so make sure the Fluker's lamp has a ceramic socket, not plastic. I burned my carpet with the lamp, which shows how hot they can really get. They will lower the humidity, so be careful about that.
