I had fluorescent in my garage and I replaced them with LEDs from Home Depot. I used the kind with the LEDs built in to the fixture and thankfully i haven't had any failures yet but if I do I will have to replace the entire fixture. This was about 5 years ago so I don't even know if they still sell the same exact fixtures I bought. Next time would definitely get LED fixtures with replaceable lights.

The reason I went with LEDs was because I live in the northeast and in the winter the fluorescent lamps took about 20 to 25 minutes to start lighting up. Unfortunately, my garage is not insulated and the fluorescent lamps don't do very well in the cold.

I used the highest K rating I could find at the time. I think they were 4100K. If I were doing it today I would go with 5000K.
