The Ember - Tritium Glow Fob

The Ember is a green tritium glow fob—a compact marker light designed to make your keys and gear easier to spot in low light. It’s the slightly larger version of the Spark Glow Fob, offering the same always-ready glow in a larger format. Attach it to your your KeyBar or the zipper on a backpack, range bag, tent, or sleeping bag for dependable visibility where you need it most.

Tritium is self-powered, so it glows without sunlight, batteries, or any outside charge, and its 12.23-year half-life means long-lasting performance over time. The Ember features an injection molded polycarbonate casing, glass breaker tip, keychain hole / lanyard loop, and includes one cylindrical tritium lamp with keyring. It measures 1.13” long (excluding keyring) and 0.31” in diameter.
