trigalight® technology

trigalight® works similar to a CRT tube formerly used in TV screens. Like TV CRT tubes our lights are built using a gas proof glass housing. The inner walls of this glass housing are coated with a very thin layer of phosphorescent powder. This powder,  in our case zinc sulfide has the ability to change electrical energy into light.
The electric energy in  the trigalight® is generated by the tritium gas, a low radiation beta emitter. When decaying the tritium looses electrons. When such an electron hits the powder layer it is captured and transformed into light.
The colours of our trigalights are therefore not dependent on the gas used but on the coating of the glass vial,  which can be varied.

The brightness however is proportional to the  pressure (quantity of gas) inside the vial.
