The eternal light question

[GpsFrontier]

I think the person was looking for a cost comparison chart, not really wanting to make there own. I don't know if dividing the lumens by the wattage will give you an accurate power consumption. But let say to make the math easy, you have a florescent light that puts out 10,000 lumens at 100 watts. 10,000 divided by 100= 100. Is that 100 kilowatts? Is that per minute, per hour? Also how would you figure out the energy consumption for appliances that don't put out light (lumens)?

It needs to be broken down into kilowatt hours in order to be able to figure out the cost per hour to run. Then the actual kilowatt hours can be multiplied by the cost per kilowatt hr on the electric bill.

I don't know how accurate it is but this link may help.

As I mentioned once you have it plugged in, you can use a KILL A WATT meter like the P3 Kill A Watt meter to tell exactly what it costs, as well as monitor cost and usage (of any electric device/appliance). The Kill A Watt meters come in all shapes and kinds, with many different options, and for as little as $18 and up. Most home improvement stores carry them.
