When operating on a photocell or timeclock the basic equation is:
(Hours per day) x (Days per year) x (Wattage per fixture) x ($ Cost per kWh*) x 0.001 = ANNUAL COST
*Total Monthly electric bill / kWh’s used = $ Cost per kWh
The kilowatt-hour (kWh) = 1000 watt-hours;
One watt-hour is the amount of energy (usually electrical) expended by a one-watt load (e.g. light bulb) drawing power for one hour. [see Wikipedia]
