If you have heat concerns in the grow room, get an enclosed reflector with ducts on both sides to duct out the heat. This is much harder to do with open reflectors. If you really want an open reflector, go with the ajust-a-wing; it projects a slightly larger area and is adjustable.! If you are using a hps with it (recommended), be sure to get the heat diffuser that goes directly under the bulb. Most ballasts have the same inner workings, so go with a BRAND NAME ballast that comes with a guarantee. Hydrofarm is a good start. Good Luck and feel free to contact me for more info.
