Once you purchase the cords and the conversoin bulbs, likely you could get one crappy new HPS, but it's up to you. Personally, I'd get 'em anyway if I could use 'em. Heck of a price if they work.
Rusty Trichome Reviewed by Rusty Trichome on . Mercury Vapor and HPS Lighting Hey All! I was wondering if a mercury vapor light that says M59 and 4H33 on it is basically stating it is compatible with Metal Halide and HPS bulbs? This may be a rudimentary question, but I am just learning about lighting. I have been using fluoros, and have decided to make the switch to HPS for a primary lighting. I just received an offer from a guy to buy a couple HPS (so he says) lights for around 40 bucks. The only catch is that I will have to splice on some extra cord to plug Rating: 5
