How many kWh does a 100W LED light use?

If you operate your lighting for 4,320 hours per year (12 hours per day, 360 days per year), the 100W PAR38 would use 432 kWh per year and the 14W LED PAR38 would use just over 60 kWh per year. In this case, the utility would pay a rebate based on the 372 kWh of energy consumption saved over the course of the year from the more efficient lighting.
