Does anyone know how to calculate via watts and amps etc...How to arrive at how many kilowatt hours will be used power wise ??? 120 volt of course..I pay between 8 and 12 cents depending on time of day etc...
Thanks in advance

Power (ie, watts) = voltage * current, so your kilowatt hours would be = current drawn * 120 VAC (rms) * length of time used, then divide by 1,000 since you want kilowatt-hours rather than just watt-hours. There is also a Vixen plug-in that will estimate it for you if you enter the power or current used by each channel.

So for example if I'm using 3088.6 watts of power for 39 hours per week and I have the lights on for 1 month (4 weeks) the calculation would be ???

3088.6 * 39 * 4 / 1000 = 481.82 kWH
