with this MH light box:
The box is 16.5in wide x 22in long x 10in deep. I will have 2 of these in my canopy (which I've yet to begin building). The lights are 400w each and lighting my 120 gal.
The questions I have are:
1) These lights will be approx 10in from the water, do they need to have a piece of glass over the top of the box? The reason I ask is because the light get's quite hot and I assume the glass would as well.
2) Would it be good design to include a vent or fan on the opposite side of the box.
3) Am I missing anything?
Thanks guys.
