^ So, 216 kwh used over the course of 3 months. Multiply 216 times your local rate (example: $0.10 per kwh) = $21.60 for three months use of a 100 watt bulb, so about $7 more per month for one 100watt bulb. Is that math correct?

Make sure you are following the correct wattage. If it's a CFL, it might be a 23 watt bulb that is equivalent to a 100 watt incandescent, but draws 25% of the power.

Be cool. Be safe. Post pics. LOL
