150 watt light - cost?

  1. Anyone know how much is costs to run 150 watts worth of lights for one hour?
  2. Really good question. I'd like to know also
  3. About 3 cents
  4. Nice.
  5. If you are looking at efficiency dont bother with a 150. They pull close to the same energy as the 250. A 600w hps is the most efficient system and they produce real dense buds.
  6. To put it this way 2 150 hps draw the same power aand emit less than half the light of a 600w hps system.
