In this case, I'd say it is best to have someone that knows their way around voltage. If you don't know what you're doing, I'd pass. Easy to do, but easy to screw-up, too.

Might be best to go with an HPS.
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
