Hand Lume Over the Years
Luminous material on hands doesn't last forever — but its degradation follows predictable patterns. Here is what to expect.
Timeline by Lume Type
| Type | Fully Bright | Noticeable Decline | Replacement Worth Considering |
|---|---|---|---|
| Radium (vintage) | N/A — aged already | Decades ago | Collector decisions only; never relume originals casually |
| Tritium tubes | Years 1–8 | Year 10–12 | After ~12 years (half-life exhaustion) |
| Super-LumiNova / Lumibrite | Indefinite | Essentially never degrades chemically | Only if physically damaged or flaking |
The Key Insight
Modern lume doesn't fade with time — it fades with damage. Super-LumiNova molecules are stable; what kills lume is physical wear: polishing during service, moisture intrusion, or UV degradation of the binder.
What Actually Dims Modern Lume
- Binder yellowing: UV exposure yellows the carrier, dimming output slightly
- Moisture damage: water under the crystal can cause flaking
- Aggressive cleaning: solvents during careless servicing
Frequently Asked Questions
Can I restore faded modern lume?
Professional reluming exists but costs often exceed replacement hand sets — see our hands guide for swap options.
Vintage tritium safety?
Intact tubes are safe; broken ones need careful cleanup. See our lume types guide.
