Use of tritium gas light sources offers a series of further benefits in addition to optimal insulation of the radioactive material. The light sources are self-illuminating, in other words they neither need battery current nor charging by means of daylight. Their luminance is almost one hundred times that of watches with traditional tritium phosphorescent paint. For the eye of the wearer, the extraordinary brightness of this light system will certainly be maintained for ten years. The hands and markings are extremely bright at night, so bright in fact that the soldier in the field should wear a cover bracelet over the watch in order to avoid being identified as a target.The light system consists of sealed, tritium-filled glass tubes, whose inside wall is coated with a phosphorescent substance. The electrons emitted by the small quantity of gas in the tube excite the this substance. Today the terms Permanent Light Technology (PLT) or Traser are used to describe this ultimate lighting system
