Quick lighting question about VHO's

I'm setting up a couple all VHO fixtures. My ballasts are going to be external from the fixture, only bulbs and reflector(obviously endcaps and wires) will be in the box. The question is, being so low heat production from VHO bulbs, do I need to add fans to the lighting box?

One setup is a 3X95W 36" and the other is a 4X110W 48".

Thanks,
Craig

You typically will want some type of air ciculation to keep heat from building up. Heat doesn't effect performance quite as much as T5s for example but I'd recommend some type of air flow.

It tank is not covered then tank temperatures will also dictate how much air flow is needed.
