I am setting up a 150 rr, that will have 6/160watt URI, VHO lamps. I only have 18 inches front to back so that is all I can get in there. At this time I do not plan on using MH because it is not pratical wit the Oceanic cap, that my very understanding wife, said I wanted.
My question is: My lights will be about 3 inches above the eggcrate, I am planing on using over the tank, in place of glass. This I hope, with the help of a 55g sump and a couple of fans will keep my tank from overheating. Do I need to have some type of cover over the lights, and if so where can I order it?
Thanks in advance for your help.

No, you don't need to do that with VHO's. You may need to clean the salt creep off the bulbs periodically to keep them efficient.
