Description

Firefly Slug Markers allow equipment and positions to be marked during low-light and darkness. Incorporating a continuously glowing light source which enables them to be seen in the dark. Slug Markers are fitted with a self-powered trigalight light source that has a maintenance-free service life of more than 10 years.

Slug Markers can to be seen at distances of up to 5m without resorting to electric or chemical lights. Simple, reliable and effective, operational efficiency and safety are enhanced during darkness.

Illumination
Slug Markers incorporate a trigalight 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, including under water, and in temperatures ranging from -20º to 70ºC. They are suitable for operation in Zone 0 hazardous areas.
