I've never seen a setup like that. It appears the ballast is set up to run 2 lights. I would take the name and model number off of the ballast and see if you can't google a wiring diagram for it.

I just bought a HPS lighting system which wasn't assembled when it came and had no instructions on how to put it together. I think i've managed to figure out how to set up most of it but there's one particular part I'm confused about. There is a lose wire that connects the reflector to the ballast (presumably) and on one end the live and earth wires are exposed, allowing me to connect it to the reflector, but on the other end the live and earth wires aren't exposed Rating: 5
