yeah test, i havent had any probs w/ my light. its on its first grow and its the first light i had since this little sun systems 250w mh with the ballast enclosed in the hood way back in 98. that being said, i am no expert on the subject but the galaxy is cosmetically appealing. its small (looks like a stereo amp, all adonized and stuff, with those cool heat sinks), almost cool to the touch, and u can go 240 or 110. only draws like 6amps too so i get to put more toys in my room. i mean, an old sales trainer of mine said "features tell, benefits sell", and this thing is definitely stylish. but i digress. i cool it with glass and a 6" 180cfm inline can fan. the fan has about 4ft duct between it and the light, and exhausts into a carbon filter in the closet my growbox is in. not very effective since my ac intake is in the closet my growbox is in and just sucks the hot air coming out of the filter. my legs broken though, so nothing i can do about it. so, thaths my story and i'm sticking to it
