Modularity that gives you more

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

A complete light, part by part
Light head
Cable
Battery
The same connector at every joint, unchanged for years.
Plus a handle for your hand and a mount for your harness.

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.

Step 1

Start with the light head

The head sets the beam. We make three, and each fits every Ammonite battery and cable.

LED NAUTILUS MKII
One light for everything
Flagship

LED NAUTILUS MKII

Adjustable beam angle

4.7°–60°beam, adjustable under water

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
The all-rounder

LED SOLARIS NEXTGEN

Spot for signalling, corona for the wider view

4500 lm6° spot with a bright corona

The most universal fixed-beam head. The focused spot carries your signals to the team, while the corona shows what is around you.

LED SPELEO MKII
Cave

LED SPELEO MKII

Small, handy, tightly focused

3000 lmnarrow 6° beam

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 MKII

Then add the other three parts

Each one answers a single question. Whatever you pick fits the head you chose.

Cold water

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.

One battery

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.

ACCU THERMO
Light head
T-VALVE
Heated garment
Best for: cold-water dives where a lighter, simpler configuration matters.
Two batteries
Full redundancy

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.

ACCU
Light head
ACCU THERMO
T-VALVE
Heated garment
Best for: deep dives and cave exploration.
  • 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
Wreck, reef, video

One light for every dive

NAUTILUS MKIIACCU TYPE 14Goodman Modular
4.7°–60°

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
Cave

Stay all day

SPELEO MKIIACCU TYPE 24Goodman Soft
up to 29 h

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

Fly with it
Travel

Fly with it

SOLARIS NEXTGENACCU TYPE 9Goodman Standard
90.72 Wh

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.
