I have noticed that in my shop/garage even though I have some big fluorescent fixtures with 4 48' bulbs each there are still some shadow spots. One that has bugged me was the inside of my bowls. So I found a floor lamp at a garage sale with a goose neck on the side for $10 and it works Great. Illuminates the inside of the bowl very well and allows me to see much more detail. I installed a 20W CFL and bang it works great, much better than the little cheap-o clip on I have. Nice part is I can position it so it throws a good light with very little shadows.
