Waterproof, non-toxic, and phthalate-free, it features a hook and hole for easy hanging and boasts a five-year shelf life, making it a reliable, maintenance-free emergency lighting solution. ## Description Product description The Cyalume SnapLight is a red industrial grade 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 * for safety. The internal illuminating 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 Safety Warning WARNING: Keep out of reach of children. Do not ingest. Dispose of responsibly after use. ## Features - Snap Light industrial grade red light stick for providing illumination for up to 12 hours - Measures 6" long and provides 360 degrees of illumination - Hook and hole top for hanging or attaching the light - Chemiluminescent substance is non-toxic and plastic body is phthalate free for safety - Five-year shelf life from date of manufacture for a maintenance-free alternative to other lighting ## Technical Specifications | Specification | Value | |---------------|-------| | Asin | B010S58BNY | | Batteries Are Included | No | | Brand Name | Cyalume | | Colour | Red | | Container Material Type | Plastic | | Container Type | Can | | Customer Reviews | 4.7 4.7 out of 5 stars (782) 4.7 out of 5 stars | | Fixture Features | Non-toxic,Waterproof | | Indoor Outdoor Usage | Outdoor | | Item Shape | Round | | Item Weight | 1.01 Pounds | | Manufacturer | Cyalume Technologies | | Manufacturer Part Number | 9-00721 | | Material | Wax | | Material Features | Non Toxic | | Model Number | 9-00721 | | Number Of Items | 20 | | Occasion | Emergency | | Package Size Name | 20 Pack | | Product Style | Modern | | Seasons | All Season | | Size | 20 Pack | | Unit Count | 20 count | | Wick Quantity | 1 | ## Product Details - **Are batteries included:** No - **Brand:** Cyalume - **Colour:** Red - **Container material:** Plastic - **Indoor/Outdoor usage:** Outdoor - **Item weight:** 458 g - **Material:** Wax - **Number of items:** 20 - **Occasion:** Emergency - **Shape:** Round ## Images ![Cyalume 9-00721 Snap Light Stick, 6", Red (Pack of 20) - Image 1](https://m.media-amazon.com/images/I/31eT7FBhXAL.jpg) ## Questions & Answers **Q: what color is best** A: Depends on your use... for brightness, without a doubt green. 2 reasons to get technical, first the chemical make up allows that color to glow brightest, and second is that the human eye sees this color better than any other light wavelength. If you're looking for "flares" though and need red, your best bet would be a strobe light. The red snap lights are good for low-light needs (hence using red lens flashlights in the military to read maps as the human eye doesn't pick this light up at low levels), but nowhere near what you would need for safety. Blues and whites are in the middle but don't nearly as long -better off with a LED flashlight. Go green... **Q: Can they be stored in freezing temps in a car? Gets Brutal in NY in the winter** A: they can be stored in the car and they will not freeze **Q: Is the shape like an octagon to avoid rolling on a flat surface?** A: Seems to not roll due to flat sealed end not to say it would not roll on a steep incline hope this helps **Q: Are these Coast Guard approved instead of light them up flares?** A: I can't give you any kind of legal advice ("...approved by Coast Guard..."), but I'd suggest to you that the soft and gentle glow of a Cyalume Stick would be quite close to useless if you were stranded out on the water and were waiting for the Coast Guard - anyone - to find you. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Mandatory for emergency preparedness *by on Reviewed in the United States 14 January 2024* I remember this this is the brand given out in the military. Bright and long lasting. Never had a dull one yet. They do have expiration dates but I have gone a few years past it with minimally reduced operation. Still works as advertised. But I’m sure the duration starts slacking off. Easy to turn on and nice sized hole on top to run cordage through. These are a must have for storm prep. Mind you it’s not going to light up a room but good enough to read by if held close and outstanding for marking and visibility if you choose to have each member of the family carry one. (Great use for the hole on top). A must have for any preparedness kit. ### ⭐⭐⭐⭐⭐ Good Value *by on Reviewed in Canada 1 September 2020* I have no problem recommending these chem-lites. They are bright and last a long time. Work very well for building clearing ID and markings. ### ⭐⭐⭐⭐⭐ Excellent *by on Reviewed in Canada 18 January 2026* Toujours pratique lors de pannes d'électricité, activités exterieurs a noirceur, ou pour amuser les enfants --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/100814346-cyalume-9-00721-snap-light-stick-6-red-pack-20](https://www.desertcart.pt/products/100814346-cyalume-9-00721-snap-light-stick-6-red-pack-20) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-06-19*
