I went looking for a better idea since I have five more of these units in the shop. I found a retro kit made by Commercial Electric that removes the ballast and turns a 4' shop light into an LED fixture with no ballast. Couldn't be simpler to install and gives off much bright and better lighting and cost less to use. I just finished two lamps and ordered two more retro kits to do the remainder of the garage.
Next up, Jack Black's Dead Red Root Beer. Not sure where it is bottled, but this is a Root Beer that comes with an energy drink in the form of Brazilian Guarana. I really enjoyed this drink but I did drink it late enough in the day to be left Sleepless in Seattle.
Hope all is well.
