I live in a very hot place, and have had rooms get up to a 100degr........ environment start's to become your #1 priorty when this happens, and with HO fluro's it doesnt get hot "AT All"....1000watts better for price but in your situation you must adapt...."I have no more replaceable costs on my lighting equipment" is something to look forward too price wise.
