i have a 400W hps security light, gets very hot because of built in ballast, but I had great results. I pulled almost 3 oz dry from a Lowryder 2 plant. This time around I have a portable air conditioner blasting the hot air out a dryer vent. Also take off the glass cover, it just traps heat like an oven and have a fan blowing directly on the bulb.
It came pre wired up for three prong from a craigslist guy. 100 US for the HPS and also a 100W MH.
-Check your local craigslist
I would suggest replacing the bulbs on a used one, should take standard bulbs
any questions?
