In the case of the halide there are 3 wires throughout - from outlet to socket.

In the case of the T5s there are 3 wires from outlet to ballast, then 2 wires from ballast to each bulb (one to each end cap).

What do you mean you ground via an outlet?

My understanding, and what I have seen is that when there are lights mounted in a metal frame (shop lights, kitchen lights, fish canopies, etc) there will be a green ground wire screwed into that metal frame (I don't understand how that is grounding it though lol). My understanding is that keeps you from getting zapped when you touch the metal frame, the ballast, or the bulb. So, if my "frame" is wood it won't conduct electricity so screwing a ground into a wood frame will do nothing. If I'm not screwing that green wire onto a metal frame, what am I screwing it to?
