Review on Stay Safe Anytime With Cyalume Yellow Emergency Glow Sticks - 10-Pack Of 6” SnapLight Survival Glow Sticks For Emergency And Hiking by Ray Richards

We just got the 10 pack of the yellow lights yesterday and they are great. We bought them mostly for Halloween and for possible use while camping but of course our four year old and I had to try one out (maybe I get to be the four year old too). It activated easily and lit up to full brightness seriously within 1-2 seconds! My son has had other cheap light up sticks or necklaces and they take forever to glow. The Cyalume was nearly instant and very bright. We activated it at 7pm last night and it was still extremely bright when I checked on him in bed around 10pm. At 5:55am this morning he came running into our room, waving around his glowing stick, and wanted to say "good morning." It was much more faint by that point, but when I left for work at 7:30am this morning it still had enough glow left that if you were in the dark it would have been more than enough to act as a visible marker (probably not enough light to read by though).
