TruGlo Denali Tritium Watch


#1

#2

This is the watch that really keeps going and going and going…


#3

How long does the tritium illuminate the phosphor, and how long is it radioactive?


#4

CHICAGO could have used this.


#5

Well, I have Tritium on my weapons nitesights…Had the weapon for 10 years and they are still as bright as when I got them put on.


#6

Generally 10 years is the lifespan of the 3H tubes.


#7

I looked it up. Tritium half life is 12 years, so these will be about half as bright 12 years after the tritium was created, 1/4 as bright 24 years later, 1/8 as bright in 36 years, etc.
