  1. Hey everyone.... so this is my question and I believe I know the answer to it already but I want to ask before hand just to make sure. So here goes..and dont bust my balls please..:eek:

    Does a single 600 watt HPS weather its a digital ballast or coil ballast use the same amount of power a 600 watt power supply for a computer use?

    I want to say yes it does but I just want to make sure.
  2. The 600 watt power supply for the computer uses much less than 600 watts most of the time, with more more or less power being dished out as needed; it is just rated at a maximum capacity of 600 watts. If hypothetically it were running at full power all the time then it would still probably use less energy than an hps, because the hps needs power for the ballast (maybe around 50 watts or so not sure) and the bulb.
