Always On.
Zero Power.
Self-powered tritium vials. No batteries. No charging. Just pure, self-sustained light for up to 25 years.
Tritium Sealed in Glass
Hydrogen-3 isotope undergoes natural beta decay, releasing low-energy electrons
Electrons Excite Phosphor
Beta particles strike the thin phosphor coating on the inner glass wall
Steady Continuous Glow
Phosphor emits a constant visible light for up to 25 years ā no external energy needed
Zero Power. Pure Light.
Beta decay of hydrogen-3 produces a self-sustained glow. No charging, no batteries, no UV activation ā ever.
Self-Powered
Generates its own light through natural radioactive decay, 24/7, for decades.
Mil-Spec Heritage
Trusted in aviation, military optics, and aerospace where darkness is the norm.
Swiss Precision
Manufactured in Switzerland under strict quality control. Directly imported.
Sealed & Safe
Hermetically sealed borosilicate glass with phosphor coating. Maintenance-free.
Choose Your Glow
Each color has a distinct brightness. Green is the brightest and most popular for maximum visibility.
Among the standard colors, green is perceived by the human eye as the brightest. Due to differences in visual perception, the other colors appear dimmer by the following amounts. For maximum visibility in low light, Green and Yellow are the strongest choices.
Three Sizes. One Standard.
