I have 2
HQIs and 2
PCs. The
MH bulbs have a UV shield, and the
PCs have a sheet of acrylic or plexiglass or whatever in front of it. My lights are about 7 or 8 inches off the water, and I TRY to wipe them off every week, but it's usualy more like every other week. I can deffinitely tell the difference if it goes any longer than that. I would think if you could rig up some kind of shield, it might make your life a LOT easier. I don't know all the consequences of doing somthing like that (heat & humidity in the hood), but yeah, that seems like a lot of bulbs and reflectors to have to clean.
