Cyalume Yellow Chemlight 6" 12 Hours Military Grade Lightstick (per Stick) | Malaysia

The Cyalume ChemLight is a red military grade chemical light stick measuring 15 long, for providing instant 360 degree illumination, that can be seen up to a mile away for up to 12 hours in optimal conditions. The ChemLight is waterproof, non-toxic, and non-flammable. To activate the light stick, bend, snap and shake the tube. The ChemLight meets Defense Logistics Agency (DLA) and NATO Maintenance and Supply Agency (NAMSA) specifications, and National/NATO Stock Numbers (NSN) are printed on each product. The durable, waterproof, external body of the light stick is made from low density polyethylene (LDPE), and is phthalate free for safety. The light stick floats in water and works best between 40 to 80 degrees F (4 to 27 degrees C), and although the light stick works at higher or lower temperatures, it is less effective in colder temperatures. All sticks are tested at a temperature of 72 degrees F (22 degrees C) to determine the illumination duration. Each 10-degree C (50-degree F) increase or decrease in temperature doubles or halves the reaction rate, and therefore the brightness and duration. Storage at elevated temperatures (above 120 degrees F or 49 degrees C) will decrease shelf life and start to soften the plastic tube, and increase the risk of a leak. Exposure to cold temperatures will not affect the light sticks if they are warmed above 40 degrees F (4.5 degrees C) before activation, unless they are frozen (which occurs at -15 to -20 degrees F, or -26 to -29 degrees C). Humidity and atmospheric conditions do not affect the light sticks. Light sticks are chemiluminescent substances in plastic tubes that provide hours of illumination in a number of safety, industrial, and military applications. Light sticks are waterproof, non-flammable, and non-sparking, which makes them useful in hazardous situations where sparks or flame could cause an explosion. Duration is determined by the chemistry of the formulation. Brightness is affected by temperature: the warmer the temperature, the brighter the light will appear. Exposure to direct sunlight can reduce shelf life and effectiveness. The company, founded in 1970 and headquartered in West Springfield, MA, makes products under ChemLight and SnapLight brands.
