The LED ONE is an exceptionally durable, compact torch designed as a reliable backup light for technical diving or a primary light for recreational diving. It features a simple, robust construction, high light efficiency, and outstanding durability, making it an ideal tool for the most demanding underwater conditions.

Key Features:

  • Performance and Optics: Equipped with a LED delivering up to 400 lumens. A precision collimator creates a focused 6° beam, providing excellent light penetration and visibility.

  • Burn Time and Power: Powered by three AA batteries or rechargeable cells. Thanks to its efficient electronics, it offers an exceptionally long burn time of up to 7 hours of constant light.

  • Reliability and Operation: The absence of mechanical switches increases the unit's sealing and longevity. The light is operated by tightening the head. The solid Delrin® body and anodized aluminum head ensure high resistance to impacts and abrasion.

  • Compact Design: Its ergonomic shape and small dimensions allow the LED ONE to fit easily into a suit pocket or be attached to a harness. The device is depth-tested to 200 meters.

LED ONE

Backup light

A backup you can power anywhere in the world

LED ONE is our rugged backup light: 400 lm in a 6° beam, about 7 hours of light, rated to 200 m. It runs on three AA batteries, the most common battery size in the world, so you can find spares on any dive trip, from a city supermarket to a shop on a remote island.

Power: 3 × AA

The battery every shop sells.

LED ONE takes three standard AA batteries, alkaline or rechargeable NiMH. On a liveaboard, an island or a long expedition, when your spares run out the nearest shop will have more. No special cells, no charger and no plug adapter to pack.

Available everywhere

AA is the most widely sold battery size in the world. You will not be left far from home with a light you cannot power.

Disposable or rechargeable

Fit new alkaline batteries for a known, full state before a trip, or use rechargeable AA cells if you dive often and want less waste.

Long burn time

One set of three AA batteries gives about 7 hours of light from a 5 W LED.

Three compact lights, three power sources

Each of our compact lights uses the battery that suits its job. Choose the one that fits the way you dive.

LED ONE MINI · 2 × CR123A

Lithium batteries that keep their charge in storage, the power source DIR calls for in backup lights. Our smallest and lightest backup.

LED STINGRAY · 21700 Li-Ion

A rechargeable battery with its own USB-C port, for 1300 lm. Built to work as a compact primary light.

LED ONE · 3 × AA

Batteries you can buy in any shop in the world. The backup for divers who travel and dive far from home.

Replace all three AA batteries together, and do not mix old and new batteries or different types in one light.

Simple by design

No switch to fail

No switch to fail

You turn the light on and off with a quarter-turn of the head. There is no mechanical switch to wear out or leak, and a long thread with three O-rings protects against flooding when you operate it under water.

Delrin® body, hard-anodised head

Delrin® body, hard-anodised head

The body is machined from solid Delrin®, the head from hard-anodised aluminium, and the LED sits behind 6 mm tempered glass. Pressure-tested to 200 m.

Fits a pocket, sits on the harness

197 mm long, 43 mm in diameter and 370 g with batteries. The shaped body gives a firm grip, and the light stows easily on the harness under a bungee loop.
