Ammonite System - LED ONE Backup Light

Power of simplicity

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.

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

LED ONE with rugged materials and design 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

LED ONE’s reliability, it’s a key feature, stems from its simple but robust construction, materials used, build quality and minimal electronics.

The LED ONE 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.

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 200 m and protects the device from accidental water ingress when switching on and off underwater.

High light intensity, very long operation time

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

LED ONE provides an optimal combination of high light intensity, up to 400 lm, 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.

Heavy-duty and durable build

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.
