Review on Cyalume SnapLight Blue Light Sticks Occupational Health & Safety Products by Keith Alvord

I have ordered this product at least four times in the last year or so. I keep getting boxes that were made almost two years ago. For example, the box I received last month has an expiration date of May 2017, so while they're still good, they're no more than good. They have been standing still since May 2012! I have received this date three times in the last few months. This doesn't seem to happen with other colors. I don't know why they have so many old Snaplights lying around, but when I'm paying that much for a product with a 5 year shelf life, I expect them to last at least 4 good years or so. However, they work well. They're not the brightest colors, but they're not the least bright either. They give off really bright light for about half an hour and then a few hours of ambient light. They are still glowing very faintly hours after the 8 o'clock mark. If there was a way to guarantee the expiration date prior to purchase I would probably up my rating to four stars, but until then I just can't do it. It's very important to me.
