[quote=yamaha_1fan]ok so i read the FAQ's.

a 1000 watt light uses 1000 watts per hour.

[QUOTE]

no watts are a rate not a measure of magnitude. for a 1000Watt bulb you will use 1 kWH (K watt hour) which for me costs 6 cents per kWH.

So thats 24 hours * 30 days * 6 cents/1kWH=43$
harris7 Reviewed by harris7 on . how does a 1000w light relate to electric bill? i am trying to figure out how the wattage of my lights will relate to my electric bill. a know a 1000w light uses 1000watts but over what period? The ultimate goal is to keep my usgae below 3000KW hours per month, thus keeping my electric bill in a normal range. i know it will vary depending on lighting schedule but can someone tell me how to calculate it? I know it must be simple. Rating: 5
