tritium illumination
Tritium illumination is a self-powered form of illumination that is used in the tactical, watch, and aerospace industries due to its reliability.
Tritium watches glow up to 100 times more brightly than ordinary luminescent watches and require no external light source to recharge the illumination.
The biggest advantage of Tritium illumination is that it provides a constant glow throughout the night unlike traditional illumination such as
Super-LumiNovawhich will gradually fade in a matter of hours.
