I searched through quite a few threads on shop lighing and didn't find what I needed - so here goes ; I have ceilings of apx 17 to 23 feet so I'm thinking of those warehouse vapor lights or the like. Changing bulbs is an issue at that height so I need something that lasts and lights very well. I though of putting halogen spotlights on the wall but would they create a lot of heat too? I don't thing flourescents would work. Any thoughts? tia Neville
