 I have about a 15 year old Luminox Alarm clock. The lume is NOT DEAD. Still glows in the dark. Maybe not as bright as when it was new, but it is plenty readable. My six year old Luminox still glows bright as new.

"What is Tritium?
Tritium is a heavy form (isotope) of hydrogen and for this reason behaves chemically exactly like it. Pure tritium therefore, forms a gas T2 (like hydrogen forms H2).However, tritium is not stable but decays to the inert gas helium with a half-life of 12.3 years. This means that after this time half of any amount of tritium will have become helium. This transformation process is called a pure beta-decay. In this process no gamma radiation occurs and only a low energy electron is emitted."

Also:

"traser H3 watches are warranted against defects in materials and manufacture by mb-microtec for a period of two years from the date of purchase. The mb-microtec illumination system (gaseous tritium light sources) is guaranteed for 10 years. In the event of failure within this period, the watch will be repaired or replaced with an equivalent model by mb-microtec."
