Firefly Flint-Glow Tritium Safety Markers are available with a tinted enclosure (in green and ice-blue, fitted with green and ice-blue lamps respectively) or in a clear enclosure. The clear enclosure can be fitted with any single lamp from our range of nine standard colours; green, UV-blue, yellow, white, red, blue, orange, ice-blue, purple and pink. An integral stainless steel split-ring is supplied. This tool will provide the user with many years of reliable service. Firefly Flint-Glow Markers incorporate a ferrocerium (flint) rod which, when struck with a steel blade, produces an intense shower of sparks for quick and reliable fire-lighting. A self-luminous GTLS tritium light source is also incorporated, enabling dual use of the FlintGlow Marker for quick identification or location of assets in low-light and in the dark without resorting to electric or chemical lights. Simple, reliable and effective, operational efficiency and safety are enhanced during darkness.
