I went to Home Depot today and bought just the 8' Double Ended Ballast Bypass bulbs, they come two to a pack. It is a new item for them. Eliminated the ballast, then the black wire from the wall switch was wire-nutted to the two wires on the left end of the light and the white wire from the wall switch was wire-nutted to the two wires on the right end of the light. Re installed the covers on the light. Then installed the two bulbs and all can say is WOW, what a difference! The two bulbs cost $43 and a new 8' LED strip unit cost $92. Wonder if I can find these on e-bay for less. Total time to do the project, around 20 minutes. One light down and two more to go for that stall. The Utube video (not mine) below shows how to do it.
