Yup, I have two of those actually, one on the shelf from my last house and one mounted next to the garage door opener, easy access and reaches everywhere in the garage. Anna got me a battery-powered LED one too, which has proven to be extra awesome.
Still, I want parts or tools in my hands, not lights. I have spots on the walls on either side of the garage door that will get more fixtures like this some day if the mood ever strikes me, but for the little amount of work that I do back there its prolly not really worth it. Still, I have said, 'some day I want to....' for all of these little mods, so...one step at a time
Next will be compressed air outlets or a heater I think.
