Genuine Nite GlowRings MAD Nuclear Scientists LTD are the worlds largest retailer of genuine Nite GlowRings 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.

Who are we?

We are MAD Nuclear Scientists LTD a British company and proud to be the worlds largest retailer of these genuine Nite GlowRings.

Nite GlowRing packaging...its changing!!

This is very important, the manufacturers of Nite GlowRings are changing the packaging, Nite GlowRings are now being supplied in the new style packaging.

A very great deal of our customers look for Nite Glowrings and recognise them by the distinctive older style packaging when they look at listing pictures so our listing shows both, it shows the new style packaging that is now being used and it also shows the older packaging so that our returning customers can more easily find the product.

New style Packaging New style Packaging Old style Packaging How does a Nite GlowRing 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.

What colours are there, and how bright are they?

This is a list of the colours we can supply (subject to availability) and an explanation of the perceived brightness:

Green

Yellow

White

Orange

Ice Blue

Red

Pink

Purple

UV Blue

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 Nite 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?

OK, as the listing title should suggest these are "GLOW IN THE DARK", in the dark they emit a subtle glow, not a bright light, the glow they emit is NOT going to be visible in daylight, if it was they would be very bright in total darkness and not listed as glow in the dark, please don't open the package and cup the glowring to your eye exclaiming "its not working" because your eye is not going to be dark adjusted, if you don't know what a dark adjusted eye is, give google something to do, similarly it also won't work if you try to look at it in a dark corner of the room etc.

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).

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.

Shipping times.

This is important, products being shipped internationally can take much longer to be delivered in some cases than the delivery times states, the delivery times given by are based on Royal Mail's estimated delivery time to the target country NOT the recipient, once the shipment has arrived in the target country it has to clear that country’s border controls/customs before it is handed over to that country’s postal system for sorting and delivery.

We have absolutely no control over other country’s customs/border controls or postal system or how long it may be in their system.

Customs are perfectly within their rights to open any packages and inspect them and we have no control over this.

We also would like to point out that you are responsible for any additional import duties/taxes on the items.

Some country’s border control/customs can take up to 45 days to clear items.

You should also check to see if there are any delays or issues with your country’s postal system that may cause additional delays, and please bear in mind that at busy times it can take even longer for post to arrive for example as Christmas approaches.

If you are an international customer and are not willing to be patient with delivery times and understanding of the fact that we are at the mercy of your country’s customs/border control and postal system, then please do not order.

Why all of this, we try our best to give a good professional service and most people understand the issues involved, but some don’t or won't, and spoil the experience.

So from the MAD nuclear scientists, thank you in advance for your patience and understanding.
