I know I will need a ballast for my HPS bulbs but I was wondering, how much extra each month does running this bulb run your power bill up?

call your company, and ask them what is their rate per kilowatt hour. next check your bulb wattage. find out how many hours it would take for it to use 1000kw. then multiply the company rate which you recieve by the amount of kilowatt hours are in a 24 hour day. lastly, multiply by how many days are in the month.

You will find that info on your last bill.
