If I were redoing my shop lighting I'd install a sh!tload of these - possibly some in the walls about a foot off the floor !! I've used these in 4 house renos now and they're awesome and dirt cheap and because of the low current draw you can literally install 50 on a circuit and still meet code. Also, they come with their own junction box so no need for the rectangular units. Available in 4" (which I used) and 6". I bought mine off Amazon for under $10. each Oh, and since they fit flush there's no chance of hitting them with anything !
