Trigalight® GTLS technology was developed originally by the British MOD for applications in aviation. Original designs included helicopter rotor-tip markers (for night formation flying) directional markers, exit signage and in-flight refueling markers. These applications demonstrate the tough, durable nature of GTLS light sources, being deployed in extremely adverse environmental conditions yet delivering stable, specified performance over the long term. Recognising the benefits to manufacturers and users, the technology was utilised in many more MOD applications for use in the air, at sea and on land. Today, GTLS are still used in many military sighting and instrument applications including the SUSAT sight, carrier sights and standard-issue compasses.
The range of applications for these devices is limited only by the imagination. From marking an exit route underground to locating your survival pack on a mountain. From marking a safe path around your bivvy to identifying the start button on a diesel generator. Whenever you need to find your equipment or your way in the dark, there is a cost-effective, reliable and safe Firefly product that will do the job. Our products are routinely used in the following areas:
Tritium is Expensive! Cost: $30,000 per gram. Gaseous Tritium is also used in self-luminous fire safety signs which offer users the most advantageous life-cycle cost of any permanantly illuminated fire safety sign. Typically having a service life of 10+ years, self-luminous signs need no technical maintenance or spare parts during that time....
What is Tritium? First discovered by Mark Oliphant, Ernest Rutherford and Paul Harteck in 1934. It is a radioactive isotope of hydrogen mainly used in research activities, neutron generators and fusion reactors. Tritium is an isotope of Hydrogen with 2 Neutrons & 1 Proton, Deuterium has 1 neutron & 1 Proton and Hydrogen has 0 Neutron & 1 Proton. Our devic...
Radioluminescence Luminescence is the emission of light by materials that are relatively cool. This is different from the light emitted from incandescent materials, such as burning charcoal, wood, paper etc., as the light in those cases results from heat. Since the emission of light is done by relatively cooler materials, luminescence is also called cold-body radiation. Gaseous Tritium's...
