We're changing the light fixtures at work from fluorescent to LED on both the 4' and 8 fixtures. I asked my coworker how easy it was to change. He showed me the wiring diagram and it is extremely easy.
The selling point was long life and the LED's only use about 10% of the electric the fluorescents do.
I purchased ten 4' LED K6500 frosted bulbs off ebay for under $50 shipped ( including the governor

). Note- there are two types, power to one end and power to both ends. I purchased power to both ends.
Directions were included for both the starter / transformer type ( older) and also for the newer electronic type.

This is the electronic type with a coil and capacitor. There was one on each end and they get removed.
2nd pic
These are the transformer, the bigger is the old fashion type and the white boxes are the newer circuit box type.
3rd pic
This is the far side ( opposite power cord). I cut off the coil and capacitor and clipped off the wires to the inside. This is the neutral wire to this end. ( these end caps are plastic so I did not wirenut the cut wire ends ). The power end also gets the coil and capacitor removed but the outside wires are cut and the power/lead goes to inside.
It doesn't matter which end is power / neutral but they must be wired opposite for the LED to work.

Wiring instructions and tools used. Side cutters, wire strippers, small screwdriver, larger screw driver and both blue and orange wirenuts.
The larger screwdriver was put in the end cap and twisted while the small screw driver was used to pop ( loosen ) the end. various manufacturers will have different locating clips. Have fun
