LED ONE
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.
LED ONE product presentation
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.
Lithium batteries that keep their charge in storage, the power source DIR calls for in backup lights. Our smallest and lightest backup.
A rechargeable battery with its own USB-C port, for 1300 lm. Built to work as a compact primary light.
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
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
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.

Carry two
Technical agencies recommend a primary light and two backups. LED ONE comes in eight colours, so you and your team can tell your lights apart at a glance.
