Tritium Keychain Light

Mini Tritium Glowring Keychain

Tritium gas ( H3 ) is a radioactive form of ordinary Hydrogen gas ( H2 ) and makes for a very cool keychain or watch lum.

High pressure Tritium gas is sealed inside these small borosilicate glass vials, and continuously emits low energy Beta radiation (electrons). These electrons impact a special phosphor coating on the inside of the tube, which in turn emits a visible GREEN glow.

Each Tritium Light Source is a laser sealed borosilicate glass vial which has been coated internally with phosphor. In one single process, the unit is sealed by a CO2 laser and injected with gaseous Tritium. The low energy electrons emitted by the Tritium, excite the phosphor and this creates a safe, low level light without filaments or heat dissipation and no risk of fire or explosion.

These low level light sources have unique properties, they are unaffected by water, oil and most corrosive materials. They will continuously glow, and will do so for 10 to 20 years. They are totally fail-safe and maintenance free.

They require no external power source or exposure to light in order to work.

Tritium Light Sources go through a labor intensive manufacturing process with quality control being a dominant consideration. They are 100% inspected for dimensions, brightness, temperature, thermal shock and Tritium leakage. Random sample testing is performed continually for discoloration, brightness decay, reduced pressure and vibration effects.

The glass tube is sealed in a hexagonal shaped clear acrylic housing which makes them virtually indestructible. Only a very small quantity of Tritium gas in sealed within the tube… and the low-level Beta radiation cannot penetrate the inner glass tube, nor the thick acrylic housing.
