Chemlight By Cyalume Technologies 9-42300 Yellow Lightstick 10 Pack

Yellow Lightsticks for Traffic and Parking Use

This pack supplies ten yellow lightsticks designed for traffic control and parking-lot marking. Each unit provides high-intensity illumination for half an hour and includes a self-standing holder for hands-free deployment. The sticks measure six inches long and have a shelf life of four years when stored properly. They are ready for immediate use in outdoor safety applications.

Capacity and Runtime Limits

Ten sticks give up to five hours of combined light if used sequentially, suitable for a single shift or short-term incident. The half-hour duration per stick means they cannot sustain illumination through extended overnight operations without additional packs. Once activated, a stick cannot be turned off or reused, so planning for the exact number needed is essential. Storage beyond four years may reduce brightness or reliability.
