on average, approximately how much do you pay per month to run a 1000W grow light for 16 hours a day?
how much does it cost you to run 1000W per month?

Below is a table based on operating the light only 12 hours a day at 8 cents per kilowatt hour. Check your electric bill for your electric rate.
To calculate your energy cost you will need to know 3 things:
A: Your cost of energy (usually identified as "KWH" charge on your electric bill)
B: The total watts of your lighting system
C: The total operating hours ("ON" time) of your lighting system per month. Formula = A * B/1000 * C = Total Energy Cost per month
So for the above table: A = $.08 , B = 460, C = 360 hours (12 per day * 30 days) = Total charge of $13.25
Additional info: Each H.I.D. light uses the amount of wattage the light is plus an additional 15% for the ballast. So, a 400 watt HPS uses 400 watts for the lamp and another 15%, or 60 watts, for the ballast - for about 460 watts total, give or take. This is a general rule and the electrical consumption could be a little more or less than this.

so an easier question would be how much does everyone pay per KWH?
does this look accurate?

Don't forget tho...you have to calculate in the taxes and surcharges into your kilowatt per hour rate....last time i checked my bill my k/hr rate was i think 9.5 cents and with the taxes and surcharges added in it came out to be around 16 cents
