Trigalight technology is used in both Luminox and Traser watches. This technology is one of the key aspects in the reliability and functionality of these products. The video below, created by MB-Microtec, will hopefully provide some insight as to how and why this technology works.

Innovative Swiss Precision Technology: The ability to manufacture the self-illuminating light technology called trigalight® is the result of decades of research and development work in the field of radio luminescence. The company mb-microtec ag is the originator and worldwide only manufacturer of watch lights based on this technology. trigalight® are independent of a battery or charging by sunlight, maintenance-free and have a guaranteed lifespan of at least 10 years.

Functional principle: trigalight® are small, airtight sealed glass tubes coated on the inside with a luminous substance. The coating is “fired” with electrons emitted by the tritium gas which causes the layer to light up (when such an electron hits the powder layer a fraction of its kinetic energy is transformed into light). With a trigalight®, the necessary electrons are created through the radioactive disintegration of tritium (an isotope of hydrogen).

Tritium: trigalight® are filled with tritium gas. Tritium is unstable and disintegrates whilst sending out beta radiation (electrons) with a half-life time of 12.3 years to helium. The electron is unable to penetrate the human skin and can be stopped without any problems by a sheet of paper. A traser® H3 watch contains 15 to 20 trigalight® for a total of no more than 1 GBq (Giga Bequerel) of tritium.
