Do you have to make your own? I saw a tutorial on how to make one with parts from radioshack that looked like it was pretty complex. Do most lights come with one or can you buy one? Also how much wiring is involved in setting up a HPS light?
k, any good sites/stores that you would recommend? And the more i read about ballasts and HPS lights the more it sounds i need to be a electrician to set it up. Ignitors, amps, fuses, routing wires, three conductor wire..
