how much would it cost to run this lamp for 100 hours????
http://www.ledwholesalers.com/store/images/uploads/Grow_Light_Panel.jpgHow much does electricity cost??It's generally in the ballpark of 0.10 per kW per hour, depending on where you live. That light is 13.8W, so 0.0138 kW x 100 hours x $0.1 = 14 cents.
