hello i made my own homemade cool hood works great cost me nothing i had the stuff around my house lowered temps by 5C working like a charm 
i just had a 400watt reflector all i did was bend the bottom edges on the reflector got the glass out of a picture frame its 2mm thick but works great, put 2 way tape on the inside of the lip and sticked the glass to it, then the back of the light were the light and cord end is i put a 4 inch ducting covered remaining opening with duct tape then for the front added a very small piece of cardboard with a hole in it and put the duct in the hole and duct taped that in place has been working awesome since i did it. Does not get to hot, cardboard does not get hot everything i smooth just changing the bulbs are gonne suck lol
