Uni dot cyalume light sticks - Uni Dot Extra Cyalume Day/Night Lights Packs - Green 10 Pack 3552

I bought both red and green. The one red one that I tested did not light up. It likely was expired. Have not checked others in the pkg. The green one activated brightly and some light continued for over three days. These are not much good for anything because they do not project enough light for any real task. They might be good for marking a spot such as an object you would want to avoid walking into in the dark.
Pros: Light lasts up to three days
Cons: Not enough light to read by
