Two problems : Once they are burning if the power glitches or if they are turned off ....it takes about 5 min or so to refire. Those are High Bay fixtures ,you may have to try to cut the reflectors down to get good light coverage. PITA
They're free.
Try them and see if you like them.
They also look good for a home garage.
If you don't like the light, the warm up time or the cost to run them, retrofit them with a $2 medium base ceramic lamp holder and screw in an LED or incandescent floodlight.
