hey what up everyone. i was just wondering if anyone had an idea or a plan on how to build a homemade air-cooled reflector for a medium base socket 150w hps?
My buddy made one of these, fairly cheap and simple. http://www.icmag.com/ic/showpost.php?p=804873&postcount=6 there is a little math involved, you might have to look up a geometry lesson or something like that but I have faith. Hope that helps.
