Micro LED Keyring Lights with Kit-marking Glow Function.

Share this:


The smallest LED keyring lights available. Pea-sized, and weighing under 5g each!

Ideal for attaching to keys or jackets, or as lighting inside handbags, wallets and pouches. Great as an ‘always there’ source of light, to quickly provide up-close illumination.

Unique ‘hybrid’ LED / photoluminescent light source. Bright green glow, allowing you to see the AtomLight in the dark, even when it is turned off. Simple ‘grip, then twist on / off’ design, preventing accidental activation.

Rugged construction with splash-proof housing. Ready to use with pre-installed batteries. Available in a pack of 3 or a value pack of 6.

Just like an atom, an AtomLight is very tiny indeed! It is the smallest LED keyring light available. At under 5g each (including the split ring) they are almost unnoticeable when carried; they make other keyring lights look huge. They can be attached to anything; they’re ideal for keys, jackets or bags. Despite its small size, the AtomLight is a very practical and useful light source.

Featuring a ‘hybrid’ LED / photoluminescent light source, which emits a green glow even when turned off; a feature that allows the AtomLight to be easily seen and found in the dark; perfect for those times when you’re fumbling to find the right key.

With a simple twist, each unit provides a gentle but useful amount of light, easily enough to illuminate a small room, search for something you have dropped or check a map. Ideal for emergencies when you need a light but the larger flashlight has been left behind. A simple splash-proof housing means they can be relied on in all outdoor conditions, and being about 50 times smaller than a typical flashlight, they can be carried with you wherever you go.

They have dozens of uses for both urban and outdoor environments. A fantastic addition to survival kits, first aid kits, or any other equipment that would benefit from the addition of a little light.

Many people today rely upon a smartphone to provide a flashlight function without the extra bulk of a normal flashlight, but all too often smartphone batteries go flat. The AtomLight will serve as a great back-up to flat battery situations without adding any noticeable bulk to your every day carry items.

AtomLights are very tough and will withstand the rigours of daily use.

The batteries on the AtomLight are replaceable, and here’s how:
1. Keep turning the light in the ‘off’ direction so it unscrews fully (the lens end will be retained by the black outer sleeve).
2. Remove the split ring and push off the black outer sleeve, the cells will now be accessible inside.
3. Replace 3x AG1 / 364 / SR621SW cells into the clear plastic sleeve that contained the old cells.
4. With the fresh cells installed in the same polarity, screw the unit back together, carefully slide the black outer sleeve back on and pop the splint ring back on.

Package contains: 3x or 6x AtomLight keyring LED lights with 20mm split rings and pre-installed batteries.
AtomLight dimensions: 14mm x 10mm diameter.
Weight: 4.8g (3.7g without split ring).
Made in the UK by Polymath Products.

    Very impressive.

    When you see just how small these are (a small garden pea) they are so bright.

    Perfect for looking inside a rucksack (attached to a zip) to map reading to finding the keyhole on your door ….. these are so useful. Lightweight, small but really bright. I’ve given a few away as gifts & I can see myself buying more.
