Cyalume 9-00721 Snap Light Stick, 6", Red (Pack of 20)

I see way too many negative comments thinking these are glow sticks for the 4th of July type events especially reviews about the red sticks. THESE ARE MEANT TO EMIT VERY LITTLE LIGHT FOR A REASON, red light is easier on the eyes which when walking around at night it means you keep more of your ability to see at night. These aren’t meant to be a significant source of light, the best uses for these are reading at night or seeing around inside your tent. Again these are not meant to be bright on purpose, please understand when buying that these are mainly meant for survival/camping and emergencies not for children to play with.

I recently purchased these red chemlights for various outdoor activities, and I must say, I'm thoroughly impressed. Here's why: 1. Exceptional Brightness: The intensity of the red glow is impressive, providing ample visibility without being overly harsh on the eyes. Whether used for signaling or enhancing visibility in low-light conditions, these chemlights deliver. 2. Long-lasting Glow: I appreciate the extended glow duration. These chemlights have proven to be reliable for extended periods, making them ideal for camping trips, night hikes, or emergency situations. 3. Sturdy Construction: The build quality is commendable. They are durable and can withstand a bit of rough handling without compromising their functionality. The outer casing is tough enough to endure outdoor adventures. 4. Easy Activation: The activation process is straightforward, making these chemlights user-friendly. A simple snap, shake, and you're greeted with a vibrant red glow. It's hassle-free, even in low-visibility situations. 5. Versatile Applications: From marking trails to creating a visible perimeter around a campsite, these red chemlights are versatile. They're a must-have for any outdoor enthusiast, providing both safety and convenience. 6. Well-packaged: The packaging ensures that the chemlights remain in top condition until you're ready to use them. Compact and lightweight, they're easy to carry in your backpack without taking up much space. Overall, I highly recommend these red chemlights for anyone in need of a reliable and bright light source in various outdoor scenarios. They've certainly earned their place in my adventure gear, and I'll be restocking when needed.

Todo bien tal cual debe ser

Each chem light is individually packaged as pictured and comes boxed up, mine was pretty beat up in transit but the individual packaging definitely helped protect the lights from activating or getting damaged. I used them for a multi-day sim and they functioned flawlessly, they take a little bit of force to snap the internal vial, but light up very quickly and brightly. They also work great for lighting up a tent at night, although you might want to retain the packaging, as they do get fairly bright and short of stuffing it back into its packaging or stuffing it under something, you'll still see the glow. They lasted me the full 12 hours as stated, although past the 8-9 hr mark, they lose a significant amount of their brightness. Overall, they worked great and I still have 8 chem lights left from last year!
