What color front sight is best?
A front sight with high visibility will make front sight focus more than a concept. Handgun sights are an extremely personal choice since every person sees the world in a different way. In general, most human eyes pick up one color faster than any other, and that color is green.
How does tritium night sights work?
The tritium vials found in gun “night sights” and wrist watches contain a small amount of tritium gas and phosphorus or other photo-sensitive materials. As the tritium breaks down and gives off energy. This energy (ionizing radiation) excites the phosphorus and causes it to glow.
Do tritium sights glow in the dark?
Tritium night sights transition from standard white dot sights during the daylight, to glowing green dots in the dark. Tritium does not need batteries and does not need to be charged with light — it simply glows!
Do tritium sights need sunlight?
Optical fiber and gold or brass bead front sights help by concentrating light from external sources, but now we have something better — tritium night sights. These sights glow in the dark without the need for an external light or power source and do not need to be charged with an external light.
Are tritium night sights worth it?

How long do tritium sights glow?
How Long Do Night Sights Last? The important thing to keep in mind about tritium sights is that they will gradually lose their effect over time. The half-life of tritium is about 12.5 years, so in a little over a decade tritium sights will glow only half as brightly as when they were first made.
Which tritium color is brightest?
Green
The difference between the signs is how much tritium the manufacturer installs. The light produced by GTLSs varies in color and size. Green usually appears as the brightest color with a brightness as high as 2 cd/m2 and red appears the least bright.
How long will tritium sights last?
Do you need to charge tritium sights?
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 our Glow in the Dark Embrite™ glow material.
How long will tritium sights glow?
Does tritium glow forever?
However, tritium gas tubes have a half life of 12 years and will need to be replaced after roughly 24 years (modern lume such as Super LumiNova doesn’t last forever, either). Tritium glows less brightly than many lume applications at full charge, but will often be brighter within the first hour as the lume fades.
Why are tritium sights so expensive?
Tritium is a self contained, autonomous light source: it doesn’t require batteries, it doesn’t need to be “charged” like phosphor night sights, it doesn’t need to be “switched on” and is extremely compact. Tritium is very expensive, coming at about 30.000$ per gram. This explains the high price of tritium sights.
Is blue or green tritium brighter?
Tritium comes in a number of different colour variants. We offer watches with green, blue and orange illumination with green appearing the brightest to the human eye, followed by blue and then orange.
Does tritium ever stop glowing?
Since Tritium is radioactive, it will glow whether or not it receives any light exposure; however its ability to glow is limited by the radioactive half-life of the material itself. This means that as Tritium ages, its ability to glow will diminish until the point that it ceases to glow at all.
