Do you mean these?Look into the Amazon LED 4' lights. Usually 4-6-8 packs. About $50 for 6. They are totally worth it. I have 4 on my 10' ceiling and it lights it up better than the 2-light fixture. Easy to mount - each light has 2 clips that screw into the wall.
I have a number of the 4ft Feit units from costco, but with the new garage being two split spaces and higher ceilings, might need more.
