OK I have 2 250w retrofit's to install. 1 SE and 1 DE, I get how to wire the + and - wires, that's no problem. I'm just wondering where the ground wirer goes? :embarrassed:do I just attach it to the reflector, like on one of the mounting screws?

guess I'm just nervous and don't want to ruin anything. :after_boom:

yes the reflector is where you would want to mount it. A lot of people will cut it off and not use it at all.

Are you talking about the neutral? Sometimes theres 3 wires thats why I am asking. The ground normally goes to the ground on the ballast just like the + the neutral would go under a screw near the socket if im not mistaken. You got black n white normally along with the green. Green is your neutral and the other 2 are your +/-

Grounding the reflector can help alleviate stray electricity in a tank.

As others said, you should ground to the reflector. Metal halides aren't as finicky, but some fluorescents will have trouble starting if you don't ground them.

cheers,
