I have eight 8 foot LED lights, each 9360 lumens for a total of 74,880 lumens in a one car garage. I painted all the walls white and did the floor in a pearl white epoxy so that light reflected off of everything. It honestly takes your eyes a few seconds to adjust to the brightness but it is amazing to work in. There is zero need for any sort of handheld shop light or anything else to help see what I'm working on. Here is a photo of some wheels I took right after I did the garage. It's like a giant photobooth.
