Anytime AC is involved its usually better to seal the room and scrub in there.
Dimmable ballasts? I'd put 600 watt bulbs in there if you do. Seriously, you are barely getting a 3.5' foot print with that reflector. I know, I have two of them. Blockbusters offer a true 4x4 foot print for around $160. Just run 600s and save on the power bill till.
Its not really so much that its sealed tight, just that there isnt a fan bringing air in or out. If I were in that setup Id probably pull air from inside the house through a duct into the lights and exhaust that outside or into the attic or whatever. So its a sealed room yet you're using external air to cool the lights, it would make keeping temps in the garage easier/cheaper.Yea that's Wat I was thinking too so we have already done the insulation how sealed do you think the room will be jus after putting up the poly plastic and taping all the edges. I haven't even insulated n sealed the garage door or put a layer of plastic over it and the ppm already noticably increases when I'm in there breathing for a while. The doors already all caulked and I sealed the window and insulated the roof with foam boards and spray foam.
