Each T25 Alarm Clock incorporates sixteen Betalight Gaseous Tritium Light Source (GTLS) which provide a reliable, safe and self-powered source of continuous radioluminescent light output. No battery or charging by ambient light is required by the GTLS during the lifetime of the product. Each GTLS comprises 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 a very low energy level. Every Betalight 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.
