Chemlight By Cyalume Technologies 9-42290 Green Lightstick 6 in 12 hr PK10 DLP Replacement Lamps

Green lightstick pack for low-light marking

This pack contains ten green Chemlight sticks, each six inches long and rated for twelve hours of illumination. They are designed for traffic and parking-lot use where temporary, portable light is required. A self-standing holder is included with every stick so it can be placed on flat surfaces without additional hardware.

Shelf-life and single-use limits

Each stick has a four-year shelf life when stored correctly, after which light output may fall below the rated duration. Because the chemistry is single-use, the sticks cannot be recharged or switched off once activated, making them unsuitable for buyers who need reusable or indefinitely storable light sources.
