Description: Compared with other similar fluorescent key chains, the biggest advantage is that it can be used under water for 100 meters and in harsh environments. There will be some cracks at the two ends of acrylic style. If you don't like it, you can choose the metal head style.Product introduction:Without any external energy, non fluorescent rod, sunlight and power supply, it can be self luminous for 15-25 years.Luminous principle:Tritium gas is an isotopic gas of hydrogen. The chemical formula H3 exists in ordinary air. Through high-tech technology, this product seals tritium gas in a special hard glass tube coated with phosphorus. Tritium emits low-energy? Particles, absorbed by phosphorous, give off light. The half-life of tritium is 12.3 years, that is, the brightness after 12.3 years is half of that now. That is, every 12.3 years, half of the tritium element becomes helium because of the release of electrons. Considering the consumption of early collection, storage and production, its brightness can be captured by human eyes for about 20 years. The theoretical luminous time is infinite. After the luminescence period, H3, which is also a very precious substance, can be used as a collection of chemical elements.Features:Zero energy consumption: self illumination, without any energy and light sourceLong service life: the service life is up to 15-25 yearsMaintenance free: easy to install without maintenance.Cold light: waterproof. Shockproof, etcScope of use:Tritium gas pipes can be directly used in aerospace, instrumentation, military industry, subway, tunnel, fire protection, collimator and other civil industries, such as jewelry, clocks, fishing gear, jewelry, luxury goods, knives, glasses, gifts and other industries.Brightness ranking:The brightness of tritium gas tube is related to the volume and different color coatings. Under the same conditions, the brightness of different colors is sorted as follows: Green > yellow > (white = ice blue) > (orange = pink) > purple > Red > blue.
