  1. hey everyone.
    Suppose i have 3 26 watt cfl lights and i run it 18/6 everyday, and $.14/KWH. How much is it going to cost me for 1 month.?
     
  2. 18 hours a day
    For 30 days
    X 3 26 watt cfls = 78 watts (.078 kwh)
    78 watts over 18 hours = 1404 watts used each day (1.404 kwh)
    1404 watts used each day for 30 days = 42,120 watts used per 30 day month (42.120 kwh)

    at $.14 an hour

    totaling $5.89 cents, more or less.

    Yeah, I'm baked enough to do the math for you. :smoking:
