A sealed plastic tube, usually 10cm long. The interior contains two chemicals separated by a plastic or thin glass membrane. When bent and shaken (mixing the chemicals) it starts a bioluminescence chemical reaction, producing a soft glow. Once the chemical reaction has run its course, the tube is discarded.

At TL–8 the glow is a soft green color and persists for 30 minutes.

At TL–9 the chemicals can produce any color, including white and infrared. The glow persists for 5 hours.

At TL–10 the chemical reaction lasts for 24 hours.
