View Full Version : Custom light kit help

I have a 1000w mh light with magnetic ballast and reflector in a big box with a glass door on it. I installed a internal 50 cfm exhaust fan on one end and a intake port on the other. Air passes over ballast - vent holes drilled in reflector - bulb - vent holes - exhaust fan. I considering moving ballest external because of weight. I will have to add a back plate out of fear my 3/8 eye bolts will pull through housing. Will I lose voltage or mess up my light? Is air cooling the ballast worth the weight and effort of the back plate? How heat does it (ballast) gererate?

The ballast actually generates a tremendous amount of heat, so I would definitely try to move the ballast outside box and/or grow room if at all possible.
