Key Chain Tube Lamp Self Luminous 25 Years Fluorescent Vial Key Ring Hurricane Emergency Survival Lights for Outdoor (Blue)

Exactly as described. Beautiful blue glow as I walk home everyday! Hopefully, it will last as long as advertised.

This blue tritium light was much dimmer than I imagined. My Russian military watch from the late 1980s had a very bright radioactive dial. Hoped for the same here, but it barely glows. I am disappointed.

not as bright as i thought it would be, can still see it pretty good in the dark, i like the fact that i can tell everyone that i have a radioactive necklace lol

Cool little lantern...definitely smaller then I thought...its not very bright. Needs to be really dark to see it
