I have a need to project a small circle of light ~15’ across a room from an unobtrusive hidden location that has power (top of a cabinet).
Tried various solutions but none were as good as a small “CREE” branded focusable AA flashlight I no longer use (Amazon, eBay, et al.)
I designed a screw-on sprung connector for the back of the “head” of the flashlight. It uses a couple of gold-plated “head pins” (from JoAnn), then an adjustable stand to allow the beam to be adjusted. The stand just snaps together, the rings for the electrical connection are glued together.
Running from a mutilated night-light at the moment, but working on scavenging power from a LED light strip up on that cabinet, that will turn on when the lights go out and off again at dawn.
