Review on Be Ready Industrial Illumination Emergency by Aaron Vang

These are VERY bright light sticks. You can definitely use them for reading. I think "12 o'clock coverage" is a pretty big stretch. I took one last photo before bed. After 7 hours it was still emitting light but much weaker than when it was first activated. It's probably fairer to say these are 6 hour glowsticks. However, I just add a few extras to my emergency kit and that's it.
