Question about tritium sights

[hackson]

Someone told me that you have to charge them up in the light? Is this true? I assumed that if they were radioactive that the just glowed....if u do charge them how do they work..either way can someone please clarify this ?

thanks

Were they grinning when they spun that yarn? Some people do that when they're putting you on.

Ot's false, it was probably a joke.

Night sights contain Vials that are filled with Tritium ... they do not require ANYTHING to be done to them in order to make them continue to glow. I believe most manufactures warranty their sights for 12 years. You will however, over the course of the 12 years, notice that they begin to lose there brightness.

You should check out the TruGlo sights. They have both Tritium and Fiber Optics. The best of both worlds. Night glow is intensified by the fiber optics and in low light to daylight they are much brighter than any sight I have tested. www.truglo.com or www.auto-laser.com They are the TFO sights

You don't have to do anything. They're radioactive.

Just install them and your good to go for about 12 years or so.

Saw a set of the TFO sights on a G26 not long ago; very nice.

The warranty is typically 12 years because the isotope Tritium has a half-life of 12.32 years; not much the sight-makers can do about that, but it is expensive to produce which is why night sights are more expensive. But they glow nicely.

Mix with Lithium Deuteride in the right equipment and you get...

Yeah. Put them under a light and they shine for 15 years.;f
