Put some of your lights above the benches, if you are standing over your bench, your body will create a shadow. I have the problem in my workshop now, 24x48, it has 9 pairs of 4' florescnets and it is ok for light but the benches are not lit enough so I had to add separate lights over each bench. Also LED's come in 2 configurations, one is omnidirectional light, the other is focused. The Focused do not have any frosting on the light tubes, they are like a spot light, the omnidirectional are a frosted light like a florescent. The omnidirectional will reflect light off of your ceiling if your fixtures do not have reflectors. Good lighting is not just thowing fixtures up, it take someone to look at everything you will do or may do in your garage and light placement is part of that equasion. Tim
Another thing to consider is putting your lights wider than your vehicle, if they are over the top, it will shadow underneath the vehicle, if it is more along the wall, it will help shine under it. I need to play with putting a light in the corner between the wall and ceiling, pointing generally down but also towards the center of the floor.
I agree with this. It's kind of like lighting a kitchen with over head lights and task lighting under all of the cabinets. In my 20'x20'x9' garage I have six 4' double T8 fluorescent fixtures on the ceiling, 1of the same on both of the overhead door rails, 2 of the same over 10' main bench, a directional spot light over by welding bench, direct lights over my man door, parts washer, shop press and air compressor cubby, 2 halogen spot lights in my blast cabinet ... I think that's it. I actually think I need to add some! lol
