How did you get them to send you a light to test. You said your having problems with heat so that tells me you don't have a big and fancy grow which makes me wonder why they sent you a light. You ought to invest and buy an a/c along with an intake fan if you don't already have one. Temperature control makes a difference in plants health and the density of your buds. It also has the extra ability to through a little extra color into plants that would otherwise just been solid green
