" i dont need to worry about pulling humid air since the lights will sealed from the water."

on the bottom half, air will only be pushed in. on the top half with the lights, that will be sealed fromt he bottom section via pieces of glass, the air will be pushed through one side and pulled out the other side. the air will be no more humid thatn room air, and may actually be drier from the heat of the MH's.
I may go ahead and get a few extra fans, just in case. thanks.
