A swingarm lamp is probably the universal solution for focused, benchtop lighting. The above rig looks pretty handy.
I use a cabinetmaker's type bench, which is too thick for the mounting clamps that come with most swingarm lamps, but it has two rows of benchdog holes the length of the bench. I made up a dog, drilled a hole in it sized to the stud on the swingarm, and can now use the dog to position the lamp anywhere on the bench, while sacrificing minimal surface area. Works for me.
