Attach a Titanium Lantern Tritium Bead to Your Keys: Step-by-Step

Check the hole before you choose your cord

The Titanium Lantern Tritium Bead attaches through a single lanyard hole with a 5.1 mm (0.20") inner diameter. That size is the first thing to verify against your keyring or cord: standard 550 paracord fits, according to the product record, but a thicker split ring or a bulky carabiner gate may not pass through cleanly.

If you plan to use a cord rather than a metal ring, measure the cord's diameter before you cut or knot anything. The bead is 13.1 mm (0.52") in diameter and 18 mm (0.71") tall, so it adds a noticeable but compact lantern shape to a key set. Grade 5 titanium keeps the housing light for daily carry.

How to attach the bead to a keyring or paracord lanyard

The sequence below follows the supplied product details. It assumes your bead already has its tritium vials installed, either by the store or by you before attachment.

1. Inspect the vials before threading anything: Confirm all installed tubes are intact and glowing in a completely dark environment. The product record asks you to do this within five calendar days of delivery. Once the bead is attached and carried, the warranty no longer covers the tritium tubes.
2. Choose your attachment point: For a keyring, use a split ring or small connector that fits through the 5.1 mm hole. For a lanyard, use standard 550 paracord. Avoid forcing a thick ring or oversized knot through the hole, since that can scratch the titanium finish.
3. Thread the cord or ring through the lanyard hole: Pass the paracord or ring through the central hole. The hole is generous enough for 550 paracord, but the bead is not designed as a load-bearing connector, so keep the attachment snug rather than hanging heavy gear from it.
4. Secure the cord with a knot or bead: If using paracord, finish with a knot or a second bead to keep the lantern bead from sliding off. The product record does not specify a particular knot, so use one you already trust for lanyard projects.
5. Carry and check periodically: After attachment, the bead becomes part of your daily carry. The warranty excludes cracks, breakage, or dimming caused by drops, impacts, or daily wear after delivery, so treat the glass vials as fragile components even though the titanium housing is durable.

Fit and material facts for your keychain setup

• Titanium Lantern Tritium Bead: Inner lanyard hole diameter: 5.1 mm (0.20"), which accommodates standard 550 paracord. This is the key measurement for deciding whether your existing keyring, cord, or connector will pass through the bead.

  

• Titanium Lantern Tritium Bead: Material: Grade 5 titanium; height 18 mm (0.71"), diameter 13.1 mm (0.52"). These dimensions tell you how much bulk the bead adds to a pocket or keychain and confirm the housing material.
• Titanium Lantern Tritium Bead: Tritium vial capacity: 4 vials, sized Φ1.5*6mm; vials are not included in the shell-only option. If you choose the shell-only variant, you will need to source vials separately before the bead can glow.

Choose the right variant before you attach

The bead is sold in several configurations: shell only (no tritium), 4 x Green Glow, 4 x Ice Blue Glow, 4 x Red Glow, and 4 x Custom Colors. The shell-only option arrives as a titanium housing without any vials, so it will not glow until you add tritium tubes. The 4 x Color options include four tritium vials and free installation by the store before shipping.

If you pick 4 x Custom Colors, the 4-slot color selector is not visible in the shop app. The product record instructs you to use the button to switch to the website for visual customization, and to leave a note at checkout with your color choices and installation preference. Also match your color order to the Slot Diagram in the product images (Slots 1–4) so the installed vials match your intended layout.

What to expect from tritium brightness on your keys

Tritium brightness varies by color due to human visual perception and the physical properties of each color. The supplied hierarchy is Green > Yellow > White > Orange > Ice Blue > Pink = Red > Purple. Green appears brightest, while Pink, Red, and Purple naturally look dimmer. These differences are inherent to tritium illumination and are not a defect.

• Green and Yellow: These provide the highest perceived brightness, useful if you want the bead to be easy to spot on a dark keyring.
• Ice Blue and White: Middle of the perceived brightness range; still visible but less intense than green.
• Red and Purple: Naturally dimmer; choose these for a subdued look rather than maximum visibility.

Installation and warranty points that affect attachment

The product record states that tritium vials are installed with UV glue for secure, long-lasting placement. If you buy the 4 x Custom Colors set or separate vials through the provided link, the store installs them before shipping. That means your bead should arrive ready to attach, but you still need to inspect it on delivery.

The warranty covers tubes that are damaged or non-glowing upon arrival only. Once the item has been put into use—attached to a keyring, carried in a pocket or bag, or dropped—no warranty, replacement, or refund is provided for the tritium tubes. Inspect and confirm glow within five calendar days of delivery, before you attach the bead to your keys.

Product facts for the Titanium Lantern Tritium Bead

• Titanium Lantern Tritium Bead: Tritium glow: 25 years with Swiss-made tubes (vials sold separately or included in 4 x Color options). This is the expected service life of the illumination, not a warranty period for the glass tubes.
• Titanium Lantern Tritium Bead: Installation method: UV glue, required for secure placement. Confirms that the vials are permanently secured in the housing, so you do not need to plan for vial removal during attachment.
• Titanium Lantern Tritium Bead: Warranty covers tubes damaged or non-glowing upon arrival only; no coverage after use. Explains why the inspection step must happen before the bead goes on your keyring.
