Metal Halide - Choices

Fun fact, 3 400W halides running 12hours a day will cost close to $40 per month in electricity!

Gee wizz..how much do you pay per kilowatt per hour? Here it's 7 cents. Surely not 40$ per month and why do you have to run it 12 hours?

That'S way too much I think.

Based on $0.08/kWh and that most 400W ballasts out there run closer to 500W a piece. So 1500W x 12hours = 18kWh x 30.4 (average days per month) = 547.2kWh x $0.08 = $43.78
