UVA/UVB bulb and heat?

[Brently]

I have recently set up a small 10g turtle tank. I have a filter and water and all the decor but I am unsure of the best approach for the light. In the basking area, which is roughly 4-5in away from the screen lid, I would like the temp to be around 80-85. What I am wondering is how much heat does a UVA/UVB bulb put off. Bare in mind that it will likely be a small hood or some light that will fit a standard 10g tank. I would love some advice so I don't waste my money. Thanks
