THE ENTIRE LISTING BEFORE BUYING; IT IS VERY IMPORTANT - ESPECIALLY THE
SECTIONS HEADED “WHAT COLOURS ARE THERE & HOW BRIGHT ARE THEY?”
AND “HOW TO ORDER MULTIPLE COLOURS”
Know what you are buying before you buy!
It is very important that you read the entire listing before buying so that you know what you are buying, and are sure this is what you want or need, so, please read the listing and if you have any questions, please ask before you buy.
We have tried to include as much useful and necessary information as
possible in this listing, without trying to blind you with science or bore you
with waffle. We are more than happy to answer any questions you may have before
you purchase, but PLEASE read the listing carefully as we will refer you back
to the listing if you ask a question which is already answered below
GlowRing Packaging for UK customers:
In order to post these items for a reasonable cost and to reduce damage in the post the GlowRing is taken out of its display package and wrapped separately for protection.
The display package is then flat-packed and both are place in a padded envelope. Giving as a gift? - Just re-assemble the display package and pop the GlowRing inside.
THE Nite GlowRing, WHAT ARE THEY?
At the heart of every GlowRing is a Swiss Trigalight™ capable of powering its light output for many years. The outer casing of the GlowRing is clear polycarbonate. The GlowRing requires NO batteries, neither does it need charging from sunlight or any other light source before it will work, its power source is completely self-contained.
HOW DO THEY WORK?
The Trigalight™ is a gas tritium light source or GTLS composed of a laser sealed borosilicate glass tube which has a special phosphor coating on its inner surface and has been filled with a small amount of tritium gas. As the tritium decays the beta particles emitted by its nuclei strike the tube’s phosphor coating causing it to emit visible light. By varying the type and combination of phosphors used it is possible to create tubes which emit different colours.
The excitation of phosphors by electrons (beta particles) used in the GTLS is the same principle used to create the television picture in the old cathode ray tube televisions, only in the case of the GTLS the electrons are provided in the form of beta rays by the disintegration of the tritium nuclei.
Tritium has a half-life of a little over 12 years so, as long as the glass core is not damaged, the Nite GlowRing will emit light for many years.
How safe is a Trigalight™?
As the electrons produced by the gaseous tritium are so low in energy, they are unable to breach a sheet of paper or to penetrate human skin.
Can a Nite GlowRing be Damaged or stop glowing.
Yes a Nite GlowRing can be damaged and so will stop glowing. Although quite tough the Nite GlowRing is NOT indestructible the inner borosilicate glass tritium lamp can break and if this happens it will stop glowing. So please understand that if you break the lamp we will NOT give you a refund or a replacement. The glass tritium lamp inside can be broken if dropped onto a hard surface or if the glowring receives a hard blow. The outer polycarbonate case of the glowring is tough and may not show signs of damage even though the glowring has received a blow hard enough to cause damage.
WHAT COLOURS ARE THERE & HOW BRIGHT ARE THEY?
This is a list of the colours we can supply (subject to availability) and an explanation of the perceived brightness:
Do all of the colours available appear to be the same brightness?
The simple answer is NO they do not, the human eye does not have a linear response to colours and is more sensitive to some colours than to others; so with the GlowRings there is quite a big difference between how you will perceive the colours to which the eye is most sensitive and to which the eye is least sensitive.
So; which GlowRing will look the brightest, and which the dimmest?
By far the brightest looking GlowRing is the Green and the dimmest the UV Blue. If you consider the Green as the brightest perceived then UV Blue will only appear to be about 15% as bright as the Green, Yellow is close to Green and is seen as about 80% as bright as the Green.
The list of colours shown above was compiled by us when looking at the GlowRings in the dark as what we perceived the order of brightness to be, from brightest at the top to dimmest at the bottom; and although there is a large difference between the brightest and the dimmest, between some of the colours it was difficult to agree on exactly the order they should be arranged in, if you do some searching on the internet you can find numerous lists of perceived brightness, some agree with ours and some differ slightly.
The important thing is: if the brightness IS important then you should select Green or Yellow if it’s not then pick a colour but expect them not to appear as bright.
What kind of brightness can I actually expect?
Firstly, these are designed as an aid to finding items in dimly lit situations, such as keys, luggage and a thousand other things we’ll leave up to you to think of.
They are not going to light up the room, or give you something to sit and read by.
How bright they will actually appear to you will depend on what we’ve said above and on how well dark-adjusted your eyes have become for example: if you go from a brightly lit situation into the dark and look at your GlowRing it won’t appear anywhere near as bright as it would if you’d been sitting in the dark for say 10 minutes and then looked at it, it takes time for your eyes to adjust to a darkened room.
How much should I rely on the colours and apparent brightness of the images used to create this listing?
This question highlights a problem you will always come across when trying to buy something from the internet based on how it looks; in this case the colour and how bright it appears.
If you look at the apparent brightness of the different colours in the listing they all probably look about the same brightness, why is this? Firstly, when taking the photographs the camera was set to a bulb (or timed exposure) setting so as to obtain an image that was bright enough to be useful. Secondly, cameras, whether film or digital based have a different response to colour sensitivity than the human eye; it is impossible to show how bright these will actually appear by showing you a photograph on a computer screen.
As for the colour it is impossible to give you an accurate representation of how you will actually see the colour, a full explanation of why would be very long but is basically as a result of the colour gamut’s of the different technologies used in bringing you the colours over the internet versus the human eye; so use the colours shown in the images as a rough guide only.
Some of the colours actually look quite similar to each other in real life, the UV Blue is supposed to be a rough approximation of the colour of an old black light lamp (blue with a hint of purple) and looks quite similar when compared to the purple GlowRing which may not be apparent on the images, where it appears more blue. So as we said, please use the images as a rough guide only.
WHAT ARE THE DIMENSIONS?
The Trigalight™ at the heart of the GlowRing is a laser sealed borosilicate tube 22.5mm tall and 3mm diameter (approximately 0.89 inches tall and 0.12 inches diameter)
The clear polycarbonate GlowRing housing the Trigalight™ is hexagonally shaped and is approximately 48mm tall and 10mm across flats of the hexagon (approximately 1.89 inches tall and 0.39 inches across flats).
The ring is a strong stainless steel split ring with an outer diameter of approximately 20mm (0.79 inches).
HOW TO ORDER MULTIPLE COLOURS?
From the eBay FAQs:
You can add items from the same or different sellers to your basket, and check out and pay for all the items in your basket at once. Each item will show up as a separate purchase with its own item number and the seller's user ID associated with it, exactly as it always has in My eBay. If you add multiple items from the same seller, the seller's items are grouped together in your eBay shopping basket.
P&P discounts are automatically applied if the seller has specified discounts in the listing. If they aren't applied automatically, you can request the P&P amount from the seller by placing your pointer over the item and selecting request total from seller.
You can also check out with selected items and save others for later.
You can also purchase any item in your basket separately. To do this, place your pointer over the item and select pay only this seller.
Note: You can only check out and pay for items from different sellers at the same time if all sellers accept the same payment method. Right now, PayPal is the only method of payment that can be used to buy items using the eBay shopping basket.
If you wish to order multiple colours and for some reason cannot ‘add to basket’ on eBay please place your orders individually but DO NOT MAKE PAYMENT immediately. This will allow us to combine your orders and adjust the shipping amount accordingly – you will then be billed correctly.
Please DO NOT select multiples of one colour and add a message to get alternate colours as this affects the stock levels on eBay and can result in items appearing as out of stock.
