Went through that 2 times now. First when compact fluorescent came out and now again to switch to LED. All my shop fluorescent fixtures were changed to T8 fixtures using LED tubes. All bulbs in the house are Std LED type. I made sure to buy Std fixtures that take a screw in bulb so I don't have to hunt for a replacement. You have to pay attention to the wavelength of the LED if you want more natural light colors---otherwise it is a real bright white light. Also, make sure that the LED bulb is UL or Edison Lab approved for safety. Lots of Chinese made stuff that can catch fire and burn because it is not UL or Edison Lab tested.
