Title: Tritium lights. Worth a look?
Post by: apelly on November 17, 2016, 10:01:43 pm
Some time ago tritium lights came to my attention, and I thought "Ha, that's pretty cool"

As usual, I haven't done anything about getting one, but I thought I'd have another look today. The usual suspects have them ranging in size from tiny to small and in price from $20 to $300.

I reckon some of you guys have beat me to this. Is it worth spending some bucks to get a tube? What's the smallest one you'd bother with?

Aren't they just fun glow in the dark toys? (fluorescent)

Don't suggest cheap Chinese crap. They have tritium contaminated with other radioactive elements, radiation from which is not stopped by the shell. They aren't highly radioactive but I wouldn't put them in the pants.
In Russian, but you may have an idea. Pure tritium shouldn't cause detection at all, because radiation will be fully absorbed by the shell. Watch at 4:30

I had Tritium sights (https://www.trijicon.com/na_en/products/product3.php?pid=GL01) on my Glock G25. They looked really bright at night. Too bad I sold that G25 a few years ago. If I ever get another Glock, I'll put Tritium sights on it again.

That is unexpectedly appealing!

i've got a green one from http://www.ebay.com/itm/Nite-GlowRing-Glow-In-The-Dark-Tritium-Clear-Case-Nine-Colours-Available-/141174790101 (http://www.ebay.com/itm/Nite-GlowRing-Glow-In-The-Dark-Tritium-Clear-Case-Nine-Colours-Available-/141174790101)

I keep it on my tent zipper when camping / on my key chain otherwise.
It's quite bright when your eyes get adjusted to dark - i would compare it to a firefly.

I don't see many normal-day applications ... maybe embed them in some gear you need to find quickly at night - i'm thinking of a head-lamp.

One good application for these is in emergency exit lighting, no need to run wire and you just need to replace the tubes every 20 years or so.

The units are expensive, but only until you consider the cost of the wiring you don't need to do and the periodic maintenance that is now on a 20 year cycle not monthly.

BetaLight were the manufacturer IIRC.

I epoxied a couple of these into slots cut into some steps in my garden so you can see where the edge of the step is is at night if the lights aren't working.  Works really well.

I have a watch with tritium. It's very bright when your eyes adapt to the dark.

We used to have these at university, hundreds of them, possibly thousands.

One day one of the student bars was being renovated and the builders doing it took out all the emergency lights and threw them in a skip with other building rubble causing some of them to be broken open. The university's principal safety officer was not amused as this required an official report to the National Radiological Protection Board of an accidental release of radioactive materials. (It was me who spotted the broken lights in the skip so I was not a welcome messenger when I reported it to the safety office.)

Lol, why were you shooting at night? I mean yea it's cool, but you can't see anything unless your range is lit up.

I had a cool watch in the late 70's with tritium -- lost it after maybe 6 months...

Like these a lot, on my second watch with them fitted. The first lasted 15 years before it went too dim for me. Also have them dotted around home, they can give a surprising amount of light if your eyes have achieved full night vision.
Trouble is I bought all mine over 10 years ago and the price seemed reasonable then, now the price seems much higher and has become too much for me.

Yeah, I had custom Tritium sites put on my H&K Mk.23; usability is *sooo* much better than run of the mill light-pipe style night sites. Personally, I prefer them over a rail mounted laser. (The laser added to the weight of the gun (plus suppressor) just makes it too heavy for my tastes.)

I have a small tritium on my keychain. I think came from deal extreme. A small chip of plastic came off case. Hope i dont get testicular cancer.
But otherwise, works really well finding my car keys in the dark. I looked at them recently and the larger ones are expensive.
