By unexposed you mean it has a reflective dome around it?
I have a Reptisun 10.0 compact flourescent in a clamp lamp with an aluminum reflector, and the position is more horizontal than vertical. When it was new, I had it about 10 inches from the turtles. Since it's getting past it's useful life, I've moved it to about 6 inches from them. My turtles have never had any problems with it, even when it was new.
Since the light tends to give of a strange hue, it's good to position the heat source (lightbulb or otherwise) so that your turtle is getting a blend of both lights.
