These look quite nice. I'm very protective of desk real estate for persistent things, though. Has anyone got a nice bright focus lamp when working on things. Most of the time my room is well-enough illuminated for things, but yesterday I was doing some minor maintenance on my 3d printer hot-end and I had to use my iPhone with the flashlight on propped up. Is there some kind of compact folding lamp which nonetheless has the ability to hold position and still be moved over specific parts of my table? Battery-operated would be ideal, but I can plug things in at worst.

Google that. It's pretty expensive for a flashlight but makes a PHENOMENAL work light. 3 brightness/focus modes, magnetic base, adjustable head, holds charge forever, and rechargable.
