Just okay
For the expressed purpose that I bought and tried the product out for the "ultra high intensity" wasn't as "ultra high instense" as I had hoped for. Didn't find it to be much brighter than a standard cyalume light stick. If you're expecting this to replace a flashlight of lantern you'll be disappointed. It does give off enough light that you won't be be tripping or bumping into things.
