LED ONE MINI
The LED ONE MINI is the most compact backup light in the Ammonite System range. It is designed for divers who require maximum reliability in a minimal form factor. Despite its small size, it provides an impressively long burn time and exceptional durability, making it an excellent backup source for technical diving or a lightweight primary light for recreational trips.
Key Features:
-
Performance and Optics: Equipped with a Cree® XPG 2 LED, it delivers 400 lumens of light. The precision collimator creates a narrow 6° beam, ideal for signaling and illuminating tight spaces.
-
Burn Time and Power: Powered by two CR123A lithium batteries (DIR approved), the light offers an outstanding burn time of approximately 5 hours and 30 minutes.
-
Rugged Construction: Made from a combination of hard-anodized aluminum (head) and Delrin® (body). It is impact-resistant and pressure-tested to 200 meters.
-
Simple Operation: To ensure maximum reliability and leak resistance, the light uses a simple "twist-to-operate" mechanism (tightening the head) with no mechanical switches.
LED ONE MINI
The backup that is ready when you need it
LED ONE MINI is our smallest backup light: 400 lm in a 6° beam, about five and a half hours of light, rated to 200 m. It has no switch and nothing to charge, because a backup has one job: to work the moment your primary light fails.
Batteries, not a rechargeable pack. On purpose.
A backup light spends most dives clipped to your harness, switched off. What matters is that it is full when you reach for it. That is why LED ONE MINI runs on two CR123A lithium batteries, the power source the DIR (Doing It Right) approach calls for in backup lights.
A known state on every dive
New batteries are full. There is no charge level to check and no question of how many cycles are behind them.
Predictable over time
Rechargeable cells keep getting better, but many professional divers find them harder to predict as charge cycles add up. A disposable battery has no cycles.
Nothing to charge
CR123A batteries hold their energy through long storage, so the light can stay on your harness between dives. Spares fit in any save-a-dive kit.
The DIR routine: new batteries every six months
Count from the first use, not from the purchase date. Replace both batteries together.
Fit two new CR123A batteries and note the date.
Switch the light on to check it.
Replace both batteries, even if they still work.
Simple by design
No switch to fail
You turn the light on by tightening 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.
Small enough to forget until you need it
130 mm long and 195 g with batteries. It fits a pocket or sits on the harness under a bungee loop, and the shaped body gives a firm grip.
Carry two
Technical agencies recommend a primary light and two backups. LED ONE MINI comes in eight colours, so you and your team can tell your lights apart at a glance.
