How Tritium Tubes Work Inside each sealed glass vial, tritium excites a phosphor coating to create a steady glow. The result is always-on illumination with no battery or charging required. B-DECAY ELECTRONS TRITIUM GAS (H-3) PHOSPHOR COATING ON INNER WALL Glows continuously for years Hydrogen-3 isotope undergoes natural beta decay inside a sealed glass vial, releasing low-energy electrons nonstop Needs no charging or maintenance Beta particles hit the phosphor coating on the inner glass wall, converting kinetic energy directly into visible light Sealed safely inside a durable capsule Phosphor emits a constant visible light for up to 25 years — all self-contained, no external energy needed When sealed, tritium vials are safe to handle. Their beta radiation is too weak to penetrate the glass vial and is easily blocked by paper. Similar light sources are commonly used in watches, exit signs, and aviation instruments. 25yr Glow lifespan Ti Gr.5 Aerospace titanium 0 Batteries needed 8 Color options 60s Color swap time Where you'll actually use it Not just a gadget. A visibility tool that earns its place on your keys. Keys & Locks Find your keyhole faster in dark parking lots, campsites, hallways, and late-night front doors. Bags & Zippers Clip it to backpacks, pouches, and zipper pulls so you can find the right pocket in low light without fumbling. Nightstand & Grab-and-Go Spot your keys, bag, or gear at a glance before sunrise, after lights out, or on your way out the door. 01 — Material Machined from Grade 5 titanium for daily carry. Real Ti-6Al-4V — the same alloy in jet engines and surgical implants. Not coated alloy, not cheap metal. 45% lighter than steel, corrosion-proof, scratch-resistant. It won't rust from sweat, won't corrode in salt water, and won't age on your keyring. 02 — Protection Built to handle drops, bumps, and everyday carry. The tritium vial sits inside a spring-loaded shock-absorbing chamber that cushions impact from every direction. In a serious drop, the outer borosilicate glass tube may shatter — but the tritium vial inside stays intact, still glowing. The spring suspension sacrifices the cheap, replaceable glass to protect the expensive tritium vial. 03 — Optics Borosilicate glass lens. Stays clear for years. Plastic yellows, scratches, and hazes within weeks. Borosilicate glass — the same material in lab beakers — keeps optical-grade clarity that won't degrade over time. The glow looks as good on year five as day one. 9mm diameter45.5mm lengthTi Gr.5 body3 × 22.5mm tritium tubeBorosilicate window~25 year glow8 colorsTool-free swap9mm diameter45.5mm lengthTi Gr.5 body3 × 22.5mm tritium tubeBorosilicate window~25 year glow8 colorsTool-free swap Eight colors. Pick your wavelength. Each color uses a different phosphor coating, so perceived brightness varies. Green reads the brightest to the human eye, with Yellow close behind — these two are the best picks for a true low-light locator. White, Orange, and Ice Blue land in the middle range: still visible, more balanced in tone. Pink, Red, and Purple are the softest — pick these when you want an ambient accent rather than a beacon. All eight colors share the same 25-year lifespan. Max visibility Best for finding keys, bag zippers, and locks in near-total darkness.

The tritium is hermetically sealed inside borosilicate glass, inside titanium. Beta particles cannot penetrate skin or glass. These devices are NRC-exempt in the US and legal to carry worldwide. You'd absorb more radiation from a banana. How bright is it in real life?Bright enough to find your keys, locate a lock, or spot your bag in total darkness. It's a locator beacon, not a flashlight. Green is the brightest color; purple is the most subtle. Does the glow really last 25 years?Tritium has a half-life of 12.3 years, so after ~12 years it's at 50% brightness. After ~25 years it's still faintly visible. Most users find it practically useful for 15+ years before swapping the tube. Can I take it on a plane?Yes. Tritium keychains are permitted in carry-on and checked luggage by TSA and IATA. They're classified as consumer self-luminous products, not hazardous materials. Why is this cheaper than competitors?We own the CNC machines. Design, manufacturing, and shipping are all in-house. No middlemen, no distributor markup. You're paying factory-direct pricing for a product others retail at 2-3x. What's included in the package?It depends on the variant you choose. If you select a color (Green, Ice Blue, etc.), you receive the titanium capsule, keyring attachment, and a pre-installed tritium vial in that color — ready to glow out of the box. If you select No Tritium (Shell Only - No Glow), you receive the titanium capsule and keyring attachment without a tritium vial, for customers who already own vials or want to source their own. How should I inspect my vial when it arrives?We recommend inspecting every vial as soon as you receive it. Here's how to verify yours in a few simple steps: Find a completely dark space — a closet or bathroom with lights off. Place the vial in total darkness. Let your eyes adjust for 30 seconds. An intact vial glows steadily on its own — no light charging needed. No glow or needs light to activate? Contact us within 5 days of delivery. What's your warranty and quality promise for the tritium vial and glass tube?Every tritium vial and borosilicate glass tube is individually inspected before shipment. The item must be inspected immediately upon opening the package on the delivery date and before any handling, test-fitting, installation, or use. The tritium vial must be checked in a completely dark environment to confirm normal glow, and the borosilicate glass tube must be carefully inspected for any cracks, chips, or other visible damage. The delivery date and time shall be determined solely by the carrier's tracking information and delivery confirmation record. Any issue must be reported to us by email no later than the end of the day following delivery. If any defect is found, photos of the defective tritium vial or glass tube together with the original packaging must be provided. Claims reported after this deadline will not be accepted. Because both the tritium vial and the outer glass tube are fragile glass components, any item that has been handled beyond initial inspection, test-fitted, installed, or otherwise used is not eligible for warranty coverage, replacement, refund, or compensation. Built to glow for decades. Built to stay on your keys. Grade 5 titanium. Tritium core. Borosilicate glass. No charging. No maintenance. Just light that lasts.
