With a plastic top, you're not going to be able to get away with much heat. The only suggestion I would have for you is to try a fluorescent blacklight and make sure that the plastic doesn't get soft from the heat.
If I were you, I'd get a regular screen top and put a dome light with a 15 watt night bulb overhead.

>>I need to know a little bit about lighting. I'm trying to get a blue or red light for the night for my 10g tank. The thing is, I have no idea where to mount it.
