Over my workbench, I had a 3ft, 2 lamp fluorescent fixture that put out 50w. I was not able to find replacement bulbs at the big box stores anymore so I replaced it with a 4ft LED shop light from Costco. All I can say is Wow! What a difference. It is rated as 42W and puts out as much light as my dual 8ft fluorescent fixtures mounted on the ceiling that use 110W bulbs.
I like the LED shop lights at Home Depot as you can directly connect them together to form as long a fixture as you need. I plan to use these in my Georgia house shop.
