Of the 8 foot florescent fixtures I have in the shop, one is dead even after trying to replace the ballast. I have 10 foot ceilings and I will need to light an area 6 x 12 for just this one fixture. I have never used these LED fixtures so I could use some help on what to get. Is that the best way to go or get a fixture that I would need to get the bulbs separately? What brand would you suggest I get and given the area I need to light what wattage should I get?
