power bill, estimting my monthly cost with lights indoors
never seen much talk about indoor lights and power bills. I'm trying to make sure i've got this figured up right. I am running a 4 bulb t5 HO, rated at 216 watts, and another small 2 bulb setup at 48 watts
264 watts, i'm being billed at around 0.11 Cents per KWH.
720 hours in a 30 day period. (30*24)
264 watts * 720 hours = 190080 total watts
190080 / 1000 (KWH) = 190.08 KWH * 0.11 = 20.9088 USD per month
Does this look right? around 20 USD per month sound about right?
