What I would add is that you also need to look at lumen output when choosing a fixture or bulb. My garage has 4’ Florescent fixtures. I looked into replacing the tubes with the led tubes and discovered that they were not as bright as a t8 5k fluorescent tube.

Also . Led sounds great , but they often fail sooner than a fluorescent. Keep in mind they are just cheap junk from CHINA . At least with a fluorescent you can replace tubes or ballast easily and inexpensively .

T5 fluorescent are even brighter.
