Depends on your use... for brightness, without a doubt green. 2 reasons to get technical, first the chemical make up allows that color to glow brightest, and second is that the human eye sees this color better than any other light wavelength. If you're looking for "flares" though and need red, your best bet would be a strobe light. The red snap lights are good for low-light needs (hence using red lens flashlights in the military to read maps as the human eye doesn't pick this light up at low levels), but nowhere near what you would need for safety. Blues and whites are in the middle but don't nearly as long -better off with a LED flashlight. Go green...

Q: What is the life shelf of the unopened Cyalume snaplight?

You all are going to think I'm making up stories, but I found a group of the Cyalume SnapLight sticks that was with some dry first aid materials that goes back to before Y2K. Perfect experiment, I thought. The green ones still glowed very brightly and although not bright were still visible 12 hours later. These things are really amazing.

Q: Can they be stored in freezing temps in a car? Gets Brutal in NY in the winter

they can be stored in the car and they will not freeze

Q: Will these give enough light to read if you need to find emergency phone numbers in phone book?

I was in a pitch black room door closed and no windows when I tried it out and I was able to find my locker and see the combination numbers on my lock. I thought it was pretty good. I'm sure you'd be able to see some emergency numbers in your phone book with this product. Hope this helped.
