You need a vented hood for your light
just get a air cool'd reflector and a fan. if your gena cool the room then ur gena have to get a ac, thats gena cost u abit and they take up to 1000w of elec. i would rather go for the air cool reflector and fan that will keep the temps right down and u wont have to go mad with the bill. if ur low on money get a cool tube and get a 200+ cfm fan to go with it, thos are ur best options
