Kwhrs saved in 2700 hrs of use if I changed my light fixtures from a 1.05 amp to .94 amp? 1 kwhr= $.10.?

Question

Trying to see what the payback would be if I purchased new , more efficient flouescent light fixtures for my shop. Current useage is 1.05 amps per fixture (T-12)and the new ones (T-8) draw .94 amps. Thanks!

Answer 1

110 x(1.05 - .94 ) X (2700 /1000) = 32.67 kwh

You'll save about $3.27. You probably can't buy the bulb for that.
