I used a 300W TopLED for my first AK-47 grow in a 3x4x5 closet. I got about an ounce of very good medicine. I just bought a second one for my second grow to run in tandem with the first. I expect better yield, but we'll see.
I have no experience with heat output from HPS (I assume it runs quite hot). The LED arrays I use do give off heat. My closet gets to 85-90C quite quickly without some ventilation. I use an exhaust fan and carbon scrubber for odor control (AK47 gives off some serious odor) and cut an inlet vent with a separate booster fan to pull room air into the closet to help keep it under 85C.
I really hope you mean 85-90 F instead of C. Otherwise those are the hottest LEDs I've ever heard of.
