Lot of 12 Cyalume, 12 Hour Yellow SnapLight Lightsticks: EXPIRATION 2024 OR BETTER!DO NOT BE FOOLED BY EXPIRATION DATES! The United States government requires manufacturers to put an expiration date on everything that is military- spec-military grade. What kills Lightsticks… If anything… Is extreme heat (120 degrees Fahrenheit +) and cold (-0 degrees or below)… Not age. Safety is a necessity for work, travel or rest. Safety depends on risk reduction. Danger is often revealed in an unexpected instant – therefore preparation is the key. Safe lighting is taken for granted until it is not there. There is a higher standard at work to adequately set the stage for safety in commerce. Cyalume builds portable lighting to this higher standard by involving employees and customers in the development of solutions that work reliably in any emergency circumstance. The most unique advantage of Cyalume chemical light products is their ability to remain operational for years, free of any dependency on batteries or electrical connections. Additional advantages include operation without spark or flame, and without oxygen consumption. Such rock solid reliability and safety in a self contained system enables the application of Cyalume technology in many demanding circumstances, where risk reduction can make a major difference in commercial operations affecting large numbers of people Developed for the Military, Cyalume SnapLights are now tested, proven, and recommended for: • Utilities: Reliable, Flameless, Waterproof lights to get the job done – indoors and out • Hotels: Evacuation lights, room and hallway lighting during power outages • Businesses: Work lighting during power outages, evacuation lights Cyalume Technologies is the sole provider of chemiluminescent light sticks to the United States Military, NATO, and FEMA. Now, public safety officials can benefit from this very same technology. Cyalume Technologies offers industrial grade Snaplights, a reliable way to see and be seen. From crime scenes to fires to HAZMAT spills, power outages, severe weather, evacuations, or motor vehicle breakdowns and crashes, being able to quickly see what is going on is an essential step to providing public safety. Cyalume Technologies maintains the highest standards and strictest quality control. Our products come with an extended shelf life and a four-year warranty. Product Description The Cyalume SnapLight is an industrial grade chemical light stick measuring 6″ 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 SnapLight is waterproof, non-toxic, and non-flammable. To activate the light stick, bend, snap and shake the tube. The light stick has a hook and gate top, for hanging or attaching the light. Each light stick is individually foil-wrapped for protection from light and moisture, and has up to a five-year shelf life from date of manufacture. The durable, waterproof, external body of the light stick is made from low density polyethylene (LDPE), and is phthalate free for safety. The internal illuminating chemical substance is non-toxic and non-flammable, and the components of the light stick are recyclable. 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. For example, the same light stick that emits approximately 30 lux (a unit that describes how much light is visible over a square meter) at 15 minutes after activation at 24 degrees C (75 degrees F) will be half as bright but glow twice as long at 14 degrees C (57 degrees F). At 34 degrees C (93 degrees F), the same light stick would be twice as bright, but glow half as long. 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). Once light sticks have been frozen, they will still produce some light, but performance will not be as reliable. 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. Viewing distance can be affected by temperature, moisture, and other elements. Exposure to direct sunlight can reduce shelf life and effectiveness. Cyalume Technologies manufactures chemiluminescent products used for safety, industrial, and military applications. The company, founded in 1970 and headquartered in West Springfield, MA, makes products under ChemLight and SnapLight brands. ChemLight products meet military specifications, and the company meets ISO 9001 standards. *Information used from Cyalume Technologies
