How much power usage for a 500w Metal halide on for 10hours a day in kilowatts?
need to figure out how much in kilowatts the fixture on my reef is costing me! I have a dual 250watt metal halide fixture (total of 500 watts) I keep the lights on for 10 hours a day. Please help!
Convert 500 W to kW by dividing by 1,000: 500/1000 = 0.5 kW
Multiply the kW by the hours: 0.5 kW x 10 hours = 5 kWh = 5 units of electrical energy.
To get the daily cost, multiply the daily kWh by the unit cost.
