Tritium Light Source: Attach mini light to item you wish to find in the dark
The Tritium Light Source available from United Nuclear is basically a keychain trinket which can be used as a fob on items you want to find in the dark. They are omnidirectional and are useful for affixing to backpacks or containers you wish to find in the dark when on those hiking and/or camping trips. '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.' Price: $29.00
