MegaGlow markers incorporate a betalight Gaseous Tritium Light Source (GTLS) which provides a reliable, safe and self-powered source of continuous light output. No battery or charging by ambient light is required during the lifetime of the product. GTLS comprise a sealed borosilicate glass capsule which contains a tiny amount of gaseous tritium, the power supply for the device. Beta-particle radiation (ie. electrons, released by the gaseous tritium as it decays) is harnessed to energise a phosphor coating on the inside surface of the capsule, causing it to glow. As a sealed source, they are non-emissive and of very low energy levels, so there is no external radiation risk. Every trigalight® source light is manufactured and tested in accordance with the UK MOD Defence Standard 62/4. GTLS contain no moving parts and, because the unit is continuously energised, an off/on switch is not required. They will remain energised for more than 10 maintenance-free years, even during extended periods of complete darkness. Trigalight® devices can be used in any environmental conditions, even under water, and in temperatures ranging from -20º to 70ºC. They are suitable for operation in Zone 0 hazardous areas.


MegaGlows are moulded in clear grade V0 polycarbonate, providing a tough protective enclosure and
making them highly shock resistant. Stainless steel end-caps provide an attractive yet durable finish.
