The Firefly Super Kit Marker offers reliable, maintenance-free visibility in complete darkness—without relying on torches, batteries, or chemical light sticks. Built for field use and emergency scenarios, each marker contains a 3 x 2.5 mm trigalight® GTLS (Gaseous Tritium Light Source) sealed in a rugged, transparent polycarbonate housing.
Visible from up to 35 metres in darkness, these markers are perfect for tagging portable gear, key locations, or safety-critical items. They’re equipped with a corrosion-resistant wire screw-clip for fast and flexible attachment to bags, boxes, tools, or stationary equipment.

How It Works:
Each Super Kit Marker uses a sealed borosilicate glass vial filled with gaseous tritium. As the gas decays, it emits beta particles that safely excite a phosphor lining, creating a continuous glow—no switches, light exposure, or upkeep needed. Safe and radiation-compliant, the GTLS operates for over a decade in total darkness and all climates.
