C-Bag,

Now that you mentioned those silly edge clamps used for the adjustable drafting lamps, I did post a simple modification for the edge clamp that seems to keep it in place better than the original design. See http://www.homemadetools.net/forum/r...0115#post11980 where these are not as elegant and with a much smaller footprint as the ones developed by morsa but I did place the wall bracket versions in several locations along the walls of the work benches and seem to do the trick.

Sorry morsa, I didn't want to hijack your posting but had to reply about the silly and almost useless edge clamps that the lamp suppliers provide.
