One system.
Many possibilities.
Every Ammonite light head, cable and battery fits every other. You choose the parts you need today, swap one when your diving changes, and replace a cable on the boat without tools.

What modular gives you
Upgrade one part, not the whole light
Want more power or longer burn time? Change the head or the battery and keep everything else.
Fix it at the dive site
A damaged cable is a spare part, not a service case. Swap it yourself in minutes, without tools, and dive.
Gear that stays current
We have kept the same connector for years, so the battery you own today works with the light head we release next.
Start with the light head
The head sets the beam. We make three, and each fits every Ammonite battery and cable.

LED NAUTILUS MKII
Adjustable beam angle
Our flagship. Narrow the beam to signal and cut through poor visibility, widen it to light the whole scene. One head covers the dives that used to need two.
See LED NAUTILUS MKII
LED SOLARIS NEXTGEN
Spot for signalling, corona for the wider view
The most universal fixed-beam head. The focused spot carries your signals to the team, while the corona shows what is around you.
See LED SOLARIS NEXTGEN
LED SPELEO MKII
Small, handy, tightly focused
A compact head that sits easily on the hand in tight passages, with a precise beam for communication and long burn times.
See LED SPELEO MKIIThen add the other three parts
Each one answers a single question. Whatever you pick fits the head you chose.

Add heating, two ways
The same system powers your heated vest, gloves or undersuit. Choose one battery for everything, or keep light and heat on separate batteries.
Light and heat from one ACCU THERMO
The simplest setup. Swap the battery for an ACCU THERMO and it powers both your light head and your heating: one battery on the harness, two outputs.
A fully professional set with separate power
A dedicated ACCU runs the primary light and a dedicated ACCU THERMO runs the heating. If one battery runs low or fails, the other system keeps working.
- Three heat levels: 0 %, 70 %, 100 %.
- ACCU THERMO 14, 24 and 24 SPECIAL.
- T-VALVE carries the power through your drysuit.
Three ways divers build it
The same parts, combined for three different kinds of diving.

One light for every dive
The flagship head with a mid-size battery. Change the beam angle during the dive instead of changing the light between dives.

Stay all day
A small head for tight passages and the largest battery. Burn time in OPERATIONAL mode outlasts the longest exploration day.

Fly with it
The all-round head with our smallest battery: about 2.1 hours of light at the full 50 W, in a size made for air travel.
Not sure where to start?
A complete set has all four parts matched and boxed together. You can change any of them later.
