How very illuminating
Sorry, this product is not available.
Of course, everyone knows that laser-sealed borosilicate glass vials that are internally coated with phosphor will create a cold energy that produces a light source when injected with gaseous tritium. It's as plain as the nose on your face.
The manufacturers of our Glowrings, who produce military equipment and other need-to-see-at-night items, have taken this everyday nugget of basic science and made it their business.
A Glowring is small enough and tough enough to attach to anything you might need to use in the dark, a bunch of keys being the most obvious. But because they can glow for up to a decade, you can leave them hanging off things that only come out once in a while like fishing gear and camping equipment. It does have to be pretty dark to see the glow, but that's the point.
This product can only be delivered to addresses within the UK.
- Length is approximately 4cm.
- Pack contains three different colours of glowring (yellow/green/purple, yellow/green/blue or yellow/green/pink); colours may vary from that pictured.
- The Glowring can be seen from as far away as 20ft in complete darkness on a clear night.
Great for camping. Drop your kit on the floor in the dark and you can find it instantly. Attach to your torch so you can find it in the bottom of your kit bag.

They really are the dogs, I have them attached to all of my scuba gear so that I am able to locate it again if I drop it, I have taken them down to 40m with no problems.

Apparently, the new radiation detectors at U.S. airports & borders can pick up these suckers.
Better not take your keys with you unless you want a free holiday in Cuba, wearing an orange suit and a nice snug hood.

These things are great, particularly if you are trying to build an H-bomb using deuterium-tritium boosting. Tritium used to be tightly regulated and hard to obtain. But not any more! The tube contains gaseous tritium. And that's why its only for sale to UK residents -- it is a "dual-use" material. So don't try taking it through customs, or you could get busted (or welcomed by various would-be nuclear powers with open arms).

Yeah, this is a great product! I've quite a few of them. They now do PINK which looks great, trust me.

These are fab. It has made my life so much easier when it comes to looking for my keys in my bag, I can see exactly where they are. Also when I get home after a few beverages it helps me see the keyhole in the dark.
