trigalight® Production Process
Due to the decay of tritium gas, trigalights are (except watch lights) not available from stock.
Each lot of lights is specifically custom made. Bench made versus laser sealed lights: Traditionally the glass container (of whatever shape and size) are coated internally with a luminescent powder, then one by one filled with tritium gas and then sealed manually. Single lights like arcs, spheres and any other shapes and forms are produced like this.
Smaller straight lights for use as watch- or gun sights illumination are produced as glass capillaries. The glass capillaries are filled manually as described above and then sliced in segments by a laser beam. Due to the laser cutting, both sealing ends of the final light are flat, not formed as a pipe as it appears with bench made lamps. Another benefit of the laser sealing process is possibility of producing ultra small lights.
In a first step, a glass vessel is manufactured to the customer’s requirements. A luminescent material (powder) is then coated onto the inner walls of the glass part.
In the next production step the glass vessel is filled with tritium gas. The tritium pressure can be also be defined by the customer. In general the higher the pressure the brighter the light will glow, but also means it will have higher activity.
