Brccee AC 1pcs Trit Vials Tritium Multicolor Self-luminous 15-Years 3x22.5mm by Superjune (Green)

I've purchased 3 so far and just ordered a fourth. These are really bright for marking equipment or putting on anything you need to find in the dark. How bright ? Well, they're not a flashlight kinda bright. However they're way brighter than my Luminox watch. I purchased both green and white. Green is the brightest due to the phosphor used, but the whit is still substantially bright. They arrived slightly sooner than the promised date, Excellently packaged.

I bought one of these to place just below the button-switch of a flashlight. I attached it with E600 glue which is transparent. Then I put a thick coat of the elastic glue over the vial for shock protection. As a result I can now use the flashlight instantly in the dark. I no longer have to search for the light or grope for the switch. The tritium vial is easily seen in at night, even across a room.

Nice and bright (for a Tritium light). I've bought several tritium lights in the past and this one is definitely the brightest I've gotten. Now keep in mind this is a tritium light, don't expect it to be ridiculously bright, but its great to find a keychain in a dark drawer or in a backpack or purse. I got this in green, which is usually the brightest, as the human eye is most tuned to green light. Again, this is quite bright for a tritium light, it must be pretty fresh!

It seems a little overpriced but it came nicely mounted in a little clear plastic vial. I use it as a calibration source for my instruments that measure the radioactivity and it works perfectly. The radioactivity is so low however that it presents no hazard unless one were to break it open. That seems unlikely as long as you keep it in its protective vial.

Good service. Good product. Not sure where others are buying anything like this cheaper. I have shopped hard and found none cheaper. I am eased with the brightness. Easier to appreciate the illumination once you have your night vision. Also, green is always going to be brighter than the other colors.

It's a decent tritium vial. As with most tritium products, you won't see the glow if it's not quite dark. But in the dark, this thing glows beautifully. Checking with calipers, it's spot on at 3 mm. The glass vial is approximately a 1 mm inner diameter tube, with 1 mm glass walls. Nice product, and comes well packaged in bubble wrap inside a clear plastic box, further padded and encased in the shipping boxes.

Didn't get a bright as they make you think. I wouldn't buy them.

I bought this because it seemed cool, I don’t really have a purpose for it so it just sits on my desk and glows all the time. It’s not an extremely bright glow but lights about about 2 inches around it in the complete dark. The plastic case it comes in is pretty cheap. I was hoping for something more like a petri dish. Instead of a plastic dental floss container. But it is what it says it is. It said it would ship in almost 2 months but came within a week and still says it hasn’t been shipped as it sits on my desk for some reason. As the glowing for 15 years goes we will see I’m on the 2nd week.
