Everyone's Favorite : A Lighting Question

[barry769]

Ok, so here is my lighting question.
I have a 30 gallon tank that I hope will be able to support even the most light demanding inhabitants like clams and sps.
I have a slightly flexible $500 budget to spend on my lighting.
What kind of lighting system do you recommend, and where is the best place to get it.

250 watt HID running an Iwasaki 6500K Mercury Vapor bulb with a 65 watt PC True Actinic Supplement.
Keeping the water below 85F may be a problem.....
