Light Tube

The Light Tube was an invention by Cadderly Bonaduce.

Design
The tube itself was a foot-long cylinder two inches in diameter. It consisted of two parts, with one end covered by a metal cap.

A disk was inserted in the tube, which had been enchanted by Histra, a priestess of Sune, with a dweomer of light as bright as pure sunlight.

Use
The metal cap on the tube shielded the light. When popped off, a focused beam of light was projected. The light beam can be adjusted by a twist of the upper part of the cylinder.
