Glow Rhino Tritium Ember FOB

Tritium Keychain Marker

The Glow Rhino Tritium Ember FOB is a small glowing marker that hangs from your keys, zipper pull or pack so you can find it in the dark. It runs on tritium, a radioactive form of hydrogen sealed inside a coated glass vial that gives off a steady glow on its own, with no batteries and no need to charge it in sunlight first. A pointed glass breaker tip on the base adds an emergency tool to something you already carry every day.

Features

• Self-Powered Tritium Lamp — One cylindrical tritium vial glows continuously day and night without batteries or exposure to light.
• 12-Year Half-Life — Tritium loses half its brightness roughly every 12 years, so the glow fades slowly over a long service life rather than dying suddenly.
• Polycarbonate Casing — The clear housing is injection molded from polycarbonate, a tough, impact-resistant plastic that protects the glass vial inside.
• Waterproof Construction — The sealed body holds up to rain, sweat and a drop in a puddle.
• Glass Breaker Tip — A pointed metal tip at the base concentrates force on a small point to help break a vehicle window in an emergency.
• Keyring And Lanyard Loop — A keychain hole with a split ring and a lanyard loop let you attach it to keys, bags, zippers or gear.
• Compact Size — The body measures 1.13 in (29 mm) long and 0.31 in (8 mm) across, not counting the keyring.
• Featherweight Carry — At about 0.02 lb (roughly 9 g), you will not notice it on a full key bunch.

Build And Materials

The tritium vial sits in a channel inside a clear polycarbonate body, so the glow shows from every side. The metal breaker tip is set into the base, and the top is drilled for the included keyring. Glow Rhino offers the Ember in several glow colors, and it is made in China.
