I have converted my fluorescent lights and the two high bay lights to LEDS, but rather than a throw away fixture I went with the tube to led replacements. Turns out they have never settled a standard for these things. Costco sells the direct replacement tube, another ebay supplier sells the power to one end only type,(other end is dummy pins) and then the third amazon type which I found out the hard way is power with black on one end and white on the other. Both the last two types require you to chop out the wires to the transistor ballast.
My bitch about leds is that the voltage reducer/power supply is a P.O.S. on all leds. I'm not sure they even last as long as regular bulbs before the switching power supply craps out. I just replaced all my shop leds as some were doing the funky chicken and two tubes had quit. They somewhat lasted 6 years, with occasional replacements of failures. So I did all 32 tubes and we will see how things go. The best leds I have are the two highbay lights which are 800 watt equivalent they claim. These have a separate power supply so when the power supply goes east, they are still good and only need a new dc voltage supply.
Kind of sad when you take out a led tube that won't light after a year, dig out the power supply from one end and hook up a dc variable voltage supply and they light up like new.
