I agree--a combination mercury vapor light will not fit in that fixture. And if it did, it should not be in that fixture. MVB's give off a lot of heat, and should be in a fixture like a dome, which traps less heat. Trapped heat will encourage a MVB to overheat and you could shorten the life of the bulb. (Which is relatively expensive to replace.)
How far away is the basking light from the basking area? I think a MVB would produce a higher temp than 82F at the distance it is.
If you're using a screen as protection, get one with larger holes (like 1/2 inch) to let more UVB rays reach your basking turtle.
