LED shop light.
I just got a couple of new LED shop lights to replace the old F40 T12s
that were cranky and did not like to start. The savings in power is significant if you had a lot of them. The LED is about 20 watts, the F40s are almost 110 watts. (19% of the power used for more light) It works out to 1.2 cents an hour per fixture Payback is somewhere around 3333 hours, minus whatever I spent on lamps. 8 hours a day for 416 days. http://gfretwell.com/electrical/LED%20shop%20light.jpg I think it is a deal. |

Plug in to the F40 fixture? Nope, the whole deal, cord and all. Unplug the old one, plug in the new one. |
