I dont know how much elect is per KwH but thats how the company meters it to you. It is probably ~$0.30/KwH (Kilowatt Hour.) Check your elec bill and it will tell you the cost. Anyways.. Watt * Hour * cost-per-hour = how much it will cost. so:
400*12*cost and 1000*24*cost.
allrightname Reviewed by allrightname on . Co$t of running lights I am thinking about getting a med. sized sea of green started up, but i am worried about the cost of my lights telling on me. Can anyone give me a ballpark figure of how much a 400w hps light cost to run 12/12? And maybe a 1000w mvh 24/7? I am just trying to make sure i have all my bases covered before i get in too deep. And to see if i am going to need a secondary power source. Rating: 5
