Halo lamps were hand-held, disc-shaped lamps that generated light around their circumference. Larger than glow rods, halo lamps were typically installed aboard starships or vehicles.

An alternate handheld version of the halo lamp also existed; no larger than the palm of a Human hand, the disc shaped light glowed with a white light that radiated outward in a three meter radius - the light source was cool to the touch, and could be easily attached to other objects.[1]
