Tritium cylindrical vials at maximum pressure.
Tritium is a radioactive isotope of Hydrogen. Tritium light sources are radioluminescent and can be best described as a strong glow. They are self-powered and do not need to be charged via exposure to light, such as standard glow pellet. Tritium does not in itself emit light but excites phosphors, thereby generating light. It is therefore most often encountered in glass capsules with an internal phosphor coating of various colors. Green is usually the brightest based on the phosphors and the sensitivity of the human eye. The half life of tritium is 12.32 years which means that a tritium based light source will be half as bright after 12.32years.
Tritium lightsources are illuminated by means of borosylicate glass tubes covered on the inside with phosphor powder and filled with gaseous tritium. The gaseous tritium emits electrons, which activate the phosphor powder producing light for 15 years (131000 hours).
Size: 23mm x 3mm
Can be used as a upgrade for Glow Fob light source or to make your own keyring fob using Crystal Clear holders for Tritium Vials.

HOLY CRAP!!! these things are so cool!!! mine just arrived today in the mail. I suggest you buy the holder for them though. they are about as big as wooden match so they can get lost easily. I made mine into a necklace. it looks pretty cool
