I just came upon this thread, one which deals with something I had find a solution to.
The shadows on my bench were really annoying and overall the light was pretty dim. I have randomly placed fluorescent's and I did have a simple desk lamp I can move around on the bench to get better direction (incandescent). I ended up putting up a single bulb short fluorescent right over my bench which really lit the place up. It was a leftover I had sitting on a back shelf which I put to good use. Made all the difference and I bought the higher grade / more expensive bulb at HD. Maybe it is that I am over 50 now and this is what happens(!)????
