Rifle Scopes Tritium life expectancy?

[mhptrooper]

I am wanting to get an ACOG for my sabre M16...I am looking into the different color options, but I have heard that the green color lasts the longest...my duty weapon has the green & is a few years old; and I have an amber colored reflex--both going strong! any truth to the colors other than green not lasting as long?

From the Trijicon Website FAQ: <div class="ubbcode-block"><div class="ubbcode-header">Quote:</div><div class="ubbcode-body">02. Do you offer different colored night sights?
Yes, Trijicon offers the choice of yellow or orange lamps in the rear sight only. We always keep the front sight green because it is the brightest and longest lasting of the colored tritium. It is also the color with the most contrast from muzzle flash. Green and yellow sights are warranted for 12 years. The orange lamp only carries a 5 year warranty.

i put green set on my PX4 Storm Beretta 45 and they light up nicely in a really dark room and i went with all green because they say they will go 12 years? Only 150.00

12 years to fade away.....7 years to dull....9 years to disappointment. Replacement? $450.

I wonder why Trijicon didn't make their scope with an option to buy without tritium for $450 less than the other models? I would rather have an aimpoint that lasts eight years on one battery than I am only out two dollors to replace the "glow"

Half life is 12.32 years. It will still glow after this just not as bright, just as it glows brighter after one year than it does after 5. It is constantly decaying. It will glow(emit Beta radiation onto a phosphor surface) for 24.64 years. This is exactly the same as the phosphor screen on a TEM where electrons hit a phosphor screen and make it glow with varying intensities.

Things can go wrong with electrical circuits that cannot with a radioactive substance. As long as the glass vial doesn't break (highly improbable as borosilicate is very strong) it will not fail. Circuits can come lose of their solder as well as short circuit from moisture.
