“ Luminous keyring. The Glowring comes in five colours: green, ice blue, orange, purple and yellow. The Glowring can be attached to anything from handbags to hound dogs - kit bags to keys and can be easily located from as far away as 50ft in dark. „
As a child I used to collect keyrings - yes, it was a bit of a rubbish hobby - but I enjoyed it, and had a fine (albeit tacky) collection consisting of all shapes and sizes. Nowadays, I don't get especially excited at the prospect of things to put on my keys - but I must admit to a slightly increased heartbeat when I saw the 'GlowRing', a small hexagonal plastic vessel (4.8 x 1cm) containing a minute amount of radioactive material. The radiation makes said GlowRing constantly emit light - no batteries or sunlight required. Now you're probably thinking that a radioactive keyring isn't safe, but the packaging states that it most certainly is - personally, I've been taught not to believe everything that I read, and I plan not to place the GlowRing anywhere near my intimate areas...
So how does it work? well, the keyring contains Tritium, a radioactive isotope of hydrogen which has a half-life of twelve years. As the Tritium degrades, it emits electrons which can be seen as light - hey presto - a glowing keyring! The Tritium is housed in a laser-sealed polycarbonate vial which has been designated 'unbreakable' (thank God!) - however, I'm not going to test it by hitting it with hammer, or running it over with the car... radiation poisoning isn't something I want in exchange for a thorough review.
The GlowRing's light should last for over ten years, which is especially impressive considering the fact that it needs no external power source to function. I should point out straightaway that the GlowRing's light is very dim, and in normal daylight you wouldn't even know it was glowing at all. However, in a pichblack room its radioactive light is plain for all to see, and is visible up to thirty feet away. The GlowRings are available in three different colours - blue, green, and pink, and they can all be picked up for the reasonable price of £9.00 from amazon.co.uk.
The GlowRing is especially good for putting on your keys, making them easy to find in the result of a power failure - similarly, i've heard stories of night fishermen tying them to the end of their lines, although personally, I'm not putting anything radioactive near my rod...
The metal loop for attaching your keys is nice and large, and the product is water resistant up to thirty metres. In terms of its weight, the GlowRing isn't at all heavy, and can easily be carried round without weighing down your pockets or bag. All in all then, if you fancy an extremely cool and maintenance free novelty keyring, then the GlowRing may be right up your street. It could be seen as a little pricey at just under £10, but it's actually a great piece of technology, and can be used as a useful marker for keys, bags, or what ever else you want to mark - highly recommended.
I have to admit that I enjoy my gadgets, gizmos and novelties. I also have to admit that many of these have no real benefit to my day to day life. Sure, there is the Creative Nomad Jukebox MP3 Player that is now an essential part of my life - as is my PSP (Playstation Portable), but I have a huge drawful of short-lived novelties that are now just sitting there, gathering dust.
If you take the time to look at the ever-growing number of gadget web sites, you will see thousands of items of various prices and quality. An item that I found and subsequently purchased on one such site a whilst back is the Traser Glowring.
The name "Traser" comes from a combination of Tritum, the main chemical element in these items, and "Laser".
The Traser Glowring was first marketed a few years ago, and is effectively a "glow in the dark" keyring. Measuring approximately 1.5" in length, these plastic fobs contain a one millimeter wide borosilicate glass tube. This tube is coated with a microscopic layer of luminescent powder.
The tube is then filled with a radiated hydrogen gas, Tritum, which causes a chemical reaction and the tube is then sealed with a laser. This method results in the tube glowing with no external light or power source for over ten years.
During the day, the glowing element is not visable, and it looks like a plain plastic keyring. However, when in a darkened room or at night, the glowring has a steady luminescent glow to it which can be clearly seen for up to 50 feet away.
I originally purchased a pack of three about two years ago, of which I put one on my keys, gave one to my girlfriend and kept the other as a spare. Because I work shift work, which often involves nights or early mornings, I find these glowrings invaluable. I normally leave my keys on the bedroom side or on the stairs, and when it is dark I can easily find them without the need of turning on any lights. (Indeed, with glowrings attached, it is probably easier to find the keys with no lights on !).
My girlfriend uses her glowring on her keys, and this makes it far easier to locate them when her keys are in the bottom of her bag.
The brilliant thing about Glowrings is that, even though they are generally marketed as keyrings, they have so many other uses. You can attach them to bags, dog collars (ideal if you walk your dog at nights !), kids schoolbags, bikes - the uses are endless. Two ideal ways that I've heard of these being used are by fishermen as lights on their lines, and as a more general use attaching them to torches in the house, so that in the event of a power cut, you can easily locate your torches.
The Traser Glowrings come with a 10 year guarantee, so in the extremely event of them failing to glow during that time, they will be replaced.
There are actually two types of Glowring on the market - the older plastic ones, and the newer type, the "X2" which are glass with metal on both ends. Cost varies, but you can expect to pay around £5 for an older model, and around £9 for a newer X2 version. Glowrings are available from most online gadget stores.
I would highly recommend Traser Glowrings. These are more than just a novelty item - they have a practical use and will last for a long, long time, making them excellent value for money.
The traser glowring is basically an everlasting glowstick. You know, one of those glowsticks that you see a lot at a club, or used to see a while back. Since then, the glowsticks seem to have gone out of fashion, but the glowring has a chance to bring it back. The glow-bit of the key ring itself looks a lot like the older, less durable versions. The difference is that this time it is encased in a plastic holder. This is for 2 reasons, the first being that it’ll make the ring more durable, and hopefully bring it closer to the manufactures “10 year glow-span guarantee”. The second reason is for the glow mechanism itself to work. The mechanism uses phosphor being in an enclosed chamber with various gases to create a cold energy that gives off a light source. Even though the manufacturers (and even various retailers) say that you can see them in total darkness up to 30 feet away, I must stress the following point. In daylight, they’re as dull as anything. At night they aren’t exactly the brightest of things, but depending on the colour you get, you may be able to just read off of the generated light, given that it’s dark enough, and that you’d have to hold the light really really close (on the paper to be precise) The strongest glowing colours I have found are purple/blue and green. There is also a yellow, but it’s not very bright. The glowrings are quite expensive as well. It costs £9.99 for a pack of 2 from the manufacturers. (You have to look at the fact that if you bought enough glowrings to last you the ten years glowing non-stop, it’d cost far more though). The advantage of buying from the manufacturers is that you can also have words written on the plastic casing. So if you want, you could have a company name, or anything else you can think of. The manufacturers site is http://www.traser.com and the cheapest online retailer I’ve found has got to be firebox.com
http://www.firebox.com. All in all, I think the glowring has got to be a good product for keys or anything small that can be lost (and found at night with the aid of the rings) but if you’re planning on showing off, you’re better off with something like a sapphire torch;)
As a bit of a novelty gadget item this ranks up there with the tops .. but doesn't quite topple the sapphire light off the throne . The manufacturers claim this little thing will glow for a good 10 years . Pretty impressive claim . I bought one of these for a laugh , considering it was only a fiver and was the closest thing to an everlasting glo-stick ( as ministry marketed it ) . I wasn't quite sure what to expect , a blinding light , a tiny glowstick or quite what . Well .. what you get is what looks like a rod made of that stuff they used to paint watch hands to make them luminous encased in a thick piece of plastic about an inch long . The glowing part inside is just shorter than an inch and quite thin compared to the width of the keyring . The light you get from the glowring is just about strong enough to read by if it was pitch black . It's useful for finding your keys on the floor when it's dark in your bedroom but it's not enough to light a room ! I've had it now for a couple of months and it is still glowing ( no suprise there ) . These are excellent gifts for people when you're really stuck - most people would probably think they're more expensive than a fiver and as an item of curiousity they're excellent . If you like novelty useless stuff and don't mind your keyring being weighed down a bit more then go and get one - a good buy for a fiver .
