We use the Ammonite LED One torch in the school at The Fifth Point. It’s rugged, heavy-duty and believe me, we’ve given it some abuse!
Manufacturer's Bumph

Power of simplicity

The Ammonite LED ONE has just been significantly upgraded.

The purpose of creating the LED ONE was to guarantee a failsafe backup against any primary light failure situation.

It offers simple construction, impressive performance, a new ergonomic military-style grip and long burn time.

With rugged materials and design, the LED ONE is a powerful yet compact backup torch with an impressive 400 lumens and 6 hour burn time all powered by three AA batteries.


Confidence in excellent performance and reliability

The Ammonite LED ONE’s reliability, (its key feature) stems from its simple but robust construction, materials used, build quality and minimal electronics.

The body is machined from a solid piece of Delrin®, an exceptionally rigid and durable construction thermoplastic. The head is made from hard anodised aluminium, which makes it resistant to abrasion and weather factors.

The LED is protected by 6mm tempered and scratch-resistant glass.

The Ammonite LED ONE head is machined with a long thread and is protected with three beefy o-rings.

It guarantees leak tightness for immersion depths up to 200m and protects the device from accidental water ingress when switching on and off underwater.


High light intensity, very long operation time

The Ammonite LED ONE delivers a tightly focused light beam of high visible cold white light.

It provides an optimal combination of high light intensity, up to 400lm, and very long operating time of over 6 hours

The back-up torch utilizes a directly powered 5W LED chip with an outstanding lifetime, lasting more than 100 000 hours of constant burning.

Three easily accessible AA batteries or equivalent rechargeable batteries can be used as the power supply source.


Extra safety

The Ammonite LED ONE head is equipped with three o-rings and with a very long thread.
Makes it almost impossible to accidentally flood it underwater by unscrewing it too much.


Heavy-duty and durable build

The LED ONE aluminium head – hard anodised – resistant to abrasion and any weather factors, the body is made of Delrin® – an exceptionally durable construction material. The LED is protected by a scratch resistant front glass made of 6mm tempered glass.



Since we only have one habitable planet, everyone has to play a part in protecting the environment.

Ammonite Systems are very much interested in preserving the environment, and they’re doing their part.

When deciding on boxes, bags, or containers, they have chosen to use recyclable cardboard packaging instead of plastic.

Recyclable packaging is a great way to extend the life of previously used materials and positively impact sustainability.
