Ammonite Nautilus Focusable Light Kit

The Ammonite Nautilus Focusable Light Kit consists of the LED Nautilus head and the Ammonite battery to meet your needs.

The variable beam LED Nautilus is Ammonite System's most versatile light with up to 4000 lumens output and an adjustable beam that can be focused from a narrow 9º to a wide 45º. With 4 to 10 hours burn time, depending on the battery and setting used, it covers a wide range of technical diving conditions.

The Ammonite Nautilus light head has been built with the technical diver in mind for demanding conditions and is bright, durable, lightweight and reliable.

Ammonite Nautilus specifications

You can select between three light kits based on battery size, power and burn time required. Each Ammonite Nautilus Focusable Light Kit contains:

  • Nautilus Light Head and HD light cable (150m operating depth)
  • Chosen Ammonite battery (100m operating depth) and charger

Ammonite Nautilus Focusable Light Kit Burn Times

Burn times vary depending on your battery and the power setting. Factors such as battery health (charge, discharge cycles and age) and ambient temperature will also affect burn times.

Each of the batteries below, the Accu 9, Accu 14 and Accu 24 can also be individually purchased, meaning you can have more than one size of battery to cover any conditions, whether just for a short dive or extended bottom time and decompression.

    Focusable Beam LED Nautilus

    From an intense 9º focus to a 45º wide, perfectly round beam, the Ammonite Nautilus Focusable Light Kit was designed with the technical diver in mind for varying demanding conditions.

    The Nautilus light head uses the latest Cree CXB LED chip with a Fresnel lens that allows you to make the most out of the impressive 4000-lumen output.

    Ammonite Batteries

    Ammonite Accu batteries are encased in a robust hard anodised canister. A lithium-ion (Li-Ion) battery pack is completely free of the so-called lazy battery effect and protected against over-voltage.

    In the standard version, the batteries are fitted with a webbing fixed loop fastening to the hip belt. The batteries can also be equipped with alternative fastening systems Sidemount Battery Holder or Accu Clic Mount.

    The transport of lithium batteries is subject to international regulation, which can differ if the batteries are transported by air, sea or road.

    All Ammonite lithium-ion (Li-Ion) batteries comply with UN Transportation Testing (UN/DOT 38.3) for Lithium Cells and Batteries and ensure the safety of your lithium batteries during shipping.

    Compact Design

    The smooth and compact design of the Ammonite Nautilus light head is perfectly balanced, making it easy to operate when in use with or without a Goodman handle. All these features are packed in relatively small housing that’s only 140mm long and 60mm in diameter. Yet while exceptionally durable, the Nautilus light head weighs 415g and 150g underwater.

Durable and reliable

    The Ammonite Nautilus light head is built from marine-grade aluminium alloy covered with a hard anode making it resistant to corrosion and mechanical scratches. The 6mm front glass is made of highly fatigue-resistant tempered glass. The Nautilus light head has been extensively tested in use and can safely go down to a depth of 150m.

Easy-to-operate switch knobs are lightweight but very tough and corrosion-resistant polymer (Delrin®).

    Take Me Home mode

    The inner microchip system signals a low battery level with a strobe flash. When drained, the battery automatically switches to the “Take me home” mode (light output at 20% light intensity).

    The "Take me home" mode is a fallback option to which Ammonite umbilical lights switch when the battery is exhausted. The light will continue to function for at least an hour or more, depending on the type of light and battery used. It will only operate in "take me home" mode until the battery is recharged.

    Ammonite System is Modular

    Due to the modular design concept, you can configure your umbilical light set according to your needs.

    All Ammonite umbilical lights, cables, standard batteries, and heating batteries are equipped with the same chinch-type connector. Consequently, there are no barriers when any part wears out or you wish to upgrade. 

    Modularity also improves convenience and safety. For example, you can replace a faulty cable with a new one at the diving site, eliminating the need to send it to the service centre.
