How long does 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.
Do you have to charge tritium sights?
Simply put, tritium is one of the most powerful technologies TRUGLO utilizes to make sights bright. It does not need batteries or need to be charged with light. It provides a constant glow for years. This makes it a great technology for emergency equipment like illuminated exit signs, watch hands, and handgun sights.
How long do TRU dot sights last?
about 15 years
Our tritium illuminated night sights and optics should last about 15 years before the tritium naturally degrades.
Are Big Dot sights good?
Big Dots are the best night sights for defensive shooting. The bright glowing golfball is impossible not to see, especially when under stress! Standard Dots are better for precision shooting at a distance. Big Dots measure 0.188″ wide and Standard Dots measure 0.140″ wide.
Is it legal to buy tritium?
Tritium sales are prohibited in the US. They can be imported but they can’t be distributed domestically.
Which tritium color is brightest?
Tritium does not in itself emit light but excites phosphors, thereby generating light. It is therefore most often encountered in glass capsules with an internal phosphor coating of various colors. Green is usually the brightest based on the phosphors and the sensitivity of the human eye.
Can you see tritium sights at night?
It’s not a lot of light, and tritium sights can be seen glowing only in the dark.
Which is better fiber optic or tritium sights?
When it comes to price, optical fiber has tritium soundly beat. Fiber optic sights regularly go for about half of the glow-in-the-dark alternative. If the dollar is your sole consideration, fiber optic is the way to go.
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.
How accurate are Xs big dot sights?
The Big/Standard Dot Difference
The XS Sights DXT2 Big Dot sight will cover about five inches of your target at 15 yards. The smaller DXT2 Standard Dot will cover about five inches of your target at 25 yards. There is a common misconception that these sights are too large for accurate shooting.

Why is tritium illegal in the US?
Because tritium is used in boosted fission weapons and thermonuclear weapons (though in quantities several thousand times larger than that in a keychain), consumer and safety devices containing tritium for use in the United States are subject to certain possession, resale, disposal, and use restrictions.
Does tritium glow forever?
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.
Is it illegal to buy tritium?
Although it is illegal for Amazon to support sales of tritium on their site, it is somewhat similar to a game of whack-a-mole. If Amazon finds the listing and shuts it down, another will pop up until they are found again.
What happens if you break a tritium vial?
What Happens When You Break a Vial of Radioactive Tritium?
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.
Do fiber optics glow in the dark?
Fiber optic rods glow brightly in bright light settings because the rod gathers light and funnels it to the rod endpoints. The longer the rod, the brighter the sight, but the fragility also increases. In low light settings, the rod is no longer visible and does not glow.
Are Red Dot sights good at night?
A: Red dot sights work very well at night. One of their primary advantages is the fact that they are illuminated, so you aren’t stuck with black iron sights or a black optic reticle on a dark background. In darkness or low-light situations, having a variable intensity red dot sight is a big advantage.
How long does a tritium vial last?
The half-life of tritium is 12.3 years; for a given amount of tritium, half the atoms will undergo radioactive decay (emitting the beta particle discussed above) in 12.3 years. The beta particle that is emitted by tritium has a very low energy.
Can you legally buy tritium?
In the US there are no legal sources of non sealed tritium vials. All Tritium vials must be sold new directly from a liscenced distributor. All re-sale of Tritium containing products are PROHIBITED in the US. § 30.19 Self-luminous products containing tritium, krypton-85, or promethium-147.
Is it legal to own tritium?
In the US, devices such as self-luminous exit signs, gauges, wristwatches, etc. that contain small amounts of tritium are under the jurisdiction of the Nuclear Regulatory Commission, and are subject to possession, distribution, and import and export regulations found in 10 CFR Parts, 30, 32, and 110.
Do night sights give off radiation?
Because the tritium night sights are in contained sights, there is no risk for radiation exposure. To be noted, tritium molecules can travel just 6mm in air before losing their radioactive charge.
What is better tritium or fiber optic sights?
Standard tritium sights will glow brighter in low-light and are more durable but lack a high-contrast color in bright light. Tritium fiber optic sights don’t glow as well as standard tritium sets, but the fiber optic rods illuminate great in bright-light settings.
Whats better tritium or fiber optic?
Do you shoot a red dot with both eyes open?
Conclusion: Shooting With Both Eyes Open
With a red-dot sight on a rifle, the drill is even easier. You will see the red dot superimposed over the target. Press the trigger and you have a hit. The other eye will give you are greater field of vision, important in personal defense or hunting.
