You have not mentioned lighting positions.
Some people have strip lights in the centre of the room, because it is the highest point of a pitched roof. Central lighting is not good for a workshop, because if your benches are against the wall you will be working in your own shadow. Then you need additional lighting.
I did the online search for lighting design when I did my workshop. For my single car garage, with a moderately low ceiling, siting the strip lights 0.5m from each wall means that I never work in the shadows. I also have fitting that have a reasonably bash proof, but low profile cover. Each fitting has two parallel small diameter tubes, which also reduces the profile. If your shed is dark, consider painting the walls.
Color, I avoid cool white. I believe it is harder on the eyes. You can buy full spectrum lighting now, and this reduces the effects of seasonally affected disorder (SAD) if you are a sufferer.
LED technology has come a long way, but get the ones with diffused light. The old type that were clusters of little 'spot lights' I find really distracting.
Just my 2C.
