CyalumeChemLight Mini Light Stick, Military Grade, 4 Hours Duration, 1.5 Inch, 50 Pack

Nice little chem lights. These are good for marking things in the dark. They are sometimes used to illuminate weapon sights, but I use them to light my dogs collar for night walks. I zip tied a piece of rubber tubing to her collar and insert the light into the end of the tubing. I can see it about 80 yards away. They last at least 4 hours.

Been using these for years, I use these and the Larger sized Calum brand lights for all sorts of stuff, be creative, activate the green ones and cut them open and rub on your body and run around like the Hulk at night, pretend you have been exposed to toxic waste. Use outdoor recreating, use indoor in emergency or for fun. the small stick are good for trail marking at night the bigger ones eliminate an large dark area, I find that Green is the best overall for lighting purposes and glow time, I often go offroading with friends in the woods and to mark our paths we nail or tie them to trees to find our way back on a safe path. They large green and white sticks can be clearly seen from 500 yards away. We sometimes use these for fishing at night with our gear to attract fish, when legal of course. I generally get 12 hours of bright light, meaning you can light a average bedroom or office in your home clearly for this amount of time, they slowly fade and around 18 hours they are pretty dim. I have hundreds of these myself- shelf life is forever, I have 25 year old onesI use and they work just the same as the newer ones.

Perfect size for a Personal/Emergency survival key. Fits right into a altoids tin and doesnt take up too much space. Illumination leaves a little to be desired, but it gives off enough brightness to help in a survival/emergency situation (i.e. needing light at night to read a map, check a compass, mark a position).

Works as expected. I don't do much with these small ones, but this is the proper size to fit inside the Trijicon RX09 reflex sight which uses these small Cyalume sticks to provide backup lighting to the reticle so it doesn't wash out in certain conditions.

I had previously bought the 6" ChemLights in various colors. They are excellent for emergency situations and very bright. I thought I would buy these small ones to see how well they work and to see how I could use them. Well, 1.5" is pretty small for a ChemLight. I tested a few and even though it states that they last for 4 hours, they lasted almost 8 hours, but the brightness tends to fade after 2 hours and remains that way for the next 4 hours before slowly fading out. This was impressive, but the amount of light is still not enough to find a good use other than to use as markers at night.I will definitely buy more of the 6" lights but not these small ones.

These lights are really bright for their size! They provide usable reading light at about 4 inches in darkness. That is far better than the dollar store version. They ate also great for night time markers.

These things suck. In all honesty, I saw the dimensions before I bought them, but I was expecting them to be brighter. If, one evening, you find yourself trapped in a cold, dark basement being pursued by a malevolent blacksmith, with no idea how to find your way out, a handful of these mini light sticks will do absolutely nothing to help you.

It's Pink. The product is listed as red but it's pink. The package says light red, which is my fault for not paying attention, and call it light red if it makes you feel good but it's pink.Light emission is impractical for much beyond a marker. I planned on using these for target markers for distance shots at night without night optics and they should do fine for that purpose. However, I was also planning to pack these for backpacking and pocket some while snowboarding for emergency purposes but the intensity of the light produced is insufficient so I will continue to carry full-size.Also, red is good for emergency markers, pink not so much.

Good seller and a good product

Las varillas de esta marca son buenas, son confiables e incluso funcionan bien aunque se usen fuera de la fecha de caducidad. Las varillas de este tamaño tienen buena capacidad de iluminación y pueden usarse para cualquier fin (recreación, por ejemplo) de manera segura. Cuando las compren con Amazon de Estados Unidos revisen que lleguen completas, a mí no me llegaron completas y no las compré en barata o con promoción, es recurrente que Amazon de Estados Unidos sea deficiente en los envíos y entregas de mercancía.

So, I put one of these things outside for a while. It was -35 Celsius. It took a bit more effort to crack, and I had to crack it in several places, but it worked fairly well.
