Okay let’s do the math.

Let’s say the fixtures use 4 20 watt LED bulbs. That is 80 watts per fixture. If run for 24 hours, 24x80, that is 1920 watts or 1.9 kWH. At 20 cents a kWH, that is about 40 cents per fixture in the school to run 24 hours in a day. If you have 50 of these fixtures running like this, that will cost you about 20 dollars a day in electricity or 600 dollars in 30 day period.

Was that too hard for the writers of this story to do?
