Screw in HID?

Discussion in 'Indoor Marijuana Growing' started by kayakbubbler, Apr 18, 2006.

  1. Are there any low wattage HPS bulbs that you can use in regular sockets? Or do all HID lights have to have a ballast?
     
  2. I've never heard of HID that could go straight to a "regular" socket, all need a ballast to my knowledge.
     
  3. They make hps bulbs that have a medium socket base (same as normal floro bulbs), but they still need a ballast.
