| I just figured up how much it cost to run one shoplight with 2-40 watt bulbs @ $.086 KWH. It cost $.12 per day to run. Every year I forget and always feel better after doing the math.
How long do you run your lights for? I may be running a little too much. |

| I grow outside via winter sowing and spring sowing. So it cost me nothing for lights. I also use recyclable containers so it cost me nothing for those expensive seed trays and heat mats all of that other bogus junk. I recycle my soil, so I do sometimes have to purchase some soil but I spend very little on that also. My main expense is the seed!! |

| I figure 10¢ per kW hour. My cost is about $2/day. That's for a 600-watt and a 400-watt MH ststem, a 125-watt LED and three 105-watt CFL bulbs running 14 hours a day. Mike |

| Your cost per KWH is unbelievably low, better check that again. Al |

| That's right, those are really cheap rates for electricity. Here in southern California they use a tiered rate system that charges more the more you use. The first 276 KWH is 13 cents a KWH. The next tier is 15 cents a KWH. I expect my 21 tube monster fluorescent light fixture to push me this month into tier 3 where they charge 24 cents a KWH. Tier 4 is 27 cents a KWH and tier 5 is 31 cents a KWH. We pay more for almost everything in California except food. Regular gas is now $3.59 a gallon, and home and land prices are some of the highest in the country. |

| I don't even want to think about it. I'm running my lights 12 hours a day. And it's a high sodium pressure lamp so I'm sure I'm going to be a nasty bill. Good thing my husband never sees the electric bill. :) |

| I just looked at my bill again and I was off a little. I used 949 KWH and my bill was $85.58. Thats the total with tax and all the other clean air stuff they add in. Cost will be wattage x hours run, divided by 1000 x price per kilowatt. So, Its .013 per day if you run it 18 hours a day. So about a nickel for every seven hours of run time. |
