I got my light today .bounty29 said:If you're interested in wiring, then here's what you'll need.
150w HPS Ballast
Medium Base 150w HPS Bulb
HID Socket
Ballast Box
Buy a bag of wire screws at Home Depot, a couple extension cords, some wire strippers, and you're good to go. Make sure if you get a medium size bulb, you get a medium base, same goes if you want to use the mogul size, get the same base and bulb so they fit. I used a mogul sized bulb the first grow, but switched to medium, because they put out the same light, and the medium is about half the size of the mogul, so it's easier to fit in my aircooled hood.
I got a 6"x6"x4" electrical box at Home Depot to put my ballast in, and I have a PC fan resting on top of the open metal box blowing into it, keeping the ballast at room temperature. The ballast will get quite hot, and there will be some vibration, so you'll want a way to have some air moving over it so it doesn't become a fire hazard, and some kind of vibration buffer. I've got mine resting on a few pieces of rockwool, none of the vibrations travel through to the cabinet.
That's what the wiring should look like. The before and after is for a security light like you were looking at, if you want to get one of those instead of the individual pieces.
A note: The ballast I linked to on 1000bulbs is a multitap, which means it can be wired for 120v, 208v, 240v, 277v.
I'm not sure where 208v and 277v would be used, but 120v is what the electrical sockets in the USA are.
There's a wiring guide printed on the ballast, I used that with the help of a few pictures like the one above, and had mine put together in like 20 minutes.
