What is Trigalight Technology?

Trigalights provide a safe, reliable and cost-effective source of continuous light over a service life of many years. Irrespective of weather conditions, temperature, altitude and humidity, trigalights will operate normally, providing versatile visual aids to help the user locate equipment, paths and positions in the dark. Nine colour options enable markers to be assigned differing functions.

Trigalights are Gaseous Tritium Light Sources (GTLS) manufactured in Bern, Switzerland by MB Microtec AG. Information on the company and details of their extensive product range can be viewed at www.mbmicrotec.com

  • Excellent reliability, particularly in extreme environmental conditions
  • Flexibility … no battery, power supply or charging needed
  • Enhanced efficiency … trigalight luminance does not affect the user’s ‘night eyes’
  • Enhanced ease of use … no switches or moving parts
  • Very low cost of ownership … no maintenance or spare parts required
  • Nine visible light colour options enable users to differentiate functions

Trigalights generate radioluminescent light, therefore no charging or switching is required. Unlike photoluminescent and chemiluminescent devices, they will continue to glow for many years, even during prolonged periods of complete darkness. No electrical power supply is needed, so there is no need to check and replace batteries. Nor is any maintenance required.

Trigalights comprise three components; gaseous tritium, phosphor and borosilicate glass. Trigalights utilise beta-particle emissions resulting from tritium decay as the energy source for light production. Tritium gas is held captive within a sealed glass vessel, coated on its internal surfaces with a fine phosphor powder. Electrons emitted by the tritium come into direct contact with and energise the phosphor, resulting in the phosphor being energized and producing continuous light output. This light is able to pass through the glass vessel walls to be harnessed in its illumination application. Light wavelength can be controlled by chemical doping of the phosphor, resulting in nine visible colours being available: green, yellow, orange, red, blue, white, ice-blue, purple and pink.
