Tritium sites ARE encapsulated in regards to the tritium itself. Half life of tritium (in sites), in my experience, is 10 years at a MINIMUM. Anybody that can afford it in the 1st place, can afford to replace them down the road.
Tritium is the perfect illumination level, unlike lighted sites which are almost useless in extreme low light due to them being too bright.
Lighted sites can FAIL!
It's obvious you are a vendor attempting to promote your products in the regular forum instead of vendor section.

I'll stick with tritium-nothing to break or battery to go down.
not a bad idea, BUT:
1.) in many countries, Tritium sights are not allowed due to #2:
2.) radio active radiation is send out as long as the Tritium is not encapsult - it´s Your own health You will offend
3.) Each 8 years Your tritium decreasesit´s lighting strength on 50%
4.) The LED-powered sight is much stronger in light output, so You could use it not only in the very dark, but also in dusk or dawn well, or say it like this 24 h a day...
