I won an eBay auction for a refurbished 400w HPS with ballast. From the looks of it, it has a metal/aluminum box attached to where you screw in the bulb, which is in turn attached to a batwing reflector. In addition, I'm getting ready to win an auction on a Pyrex Bake-A-Round. Is it possible for me to accomplish the DIY Cool Tube method? Or will I have to just make an exhaust only duct for this?
