It looks like my setup will be the same as yours. I have the DR 120 tent which looks like the same size as yours. You have 2 x 600 lights?? I was thinking one 400 watt would produce enough light for maybe six mature females but sounds like I can do more light? You seem to have done well with a total of 1200 watts without overheating? I have a 409 CFM 6 inch wind tunnel fan to cool the reflector. If you get a chance can you give me an overview of your lighting and ventilation ? Thanks RB
