FWIW, I found some LED task lamps on clearance at my local hardware and converted them to portable/magnetic shop lights, simply by removing the weighted bases and putting the wiring and guts back into a single gang switch box with a magnet attached to it. The "goose neck" is a fixed piece of tube with a pivot an each end, so it's not as convenient as a flex neck, which I would probably look for if I did the project again. At any rate, I think I have about $20 into each light, all in, and I can stick it almost anywhere in the shop for a little extra task lighting.
