ONE OF A KIND
As an experienced diver, you know perfectly how it is difficult to find a dive light that’s bright, durable, lightweight and works reliably in almost every conditions.
LED NAUTILUS is all that, but above these, it offers the adjustable beam angle (focusable) that switches between an intense focus to a wide perfectly round beam.
MOST VERSATILE DIVE LIGHT
LED NAUTILUS can be combined with different cables (E/O cord, Standard or Sidemount cable ) and different battery packs (ACCU TYPE 24, ACCU TYPE 14 and ACCU TYPE 10) or heating batteries (ACCU THERMO 24, ACCU THERMO 14, ACCU THERMO 24 Special).
POWER ADJUSTMENT
This innovative dive light utilizes the latest Cree CXB LED chip and Fresnel lens that allows to provide impressive 4000 lumens of light and smoothly adjust the light beam to as low as 9 degrees and as high as 45 degrees.
COMPACT DESIGN
All these features are packed in a relatively small housing, with only 140mm length and 60 mm in diameter.
Yet while exceptionally durable, it respectively weighs 415g and 150g underwater.
Smooth and compact design is perfectly balanced making it easy to operate when in use with Goodman handle or without.
DURABILITY AND RELIABILITY
It is built from marine aluminum alloy covered with hard anode making it resistant to corrosion and mechanical scratches.
Easy to operate switch knobs are made of lightweight but very tough and corrosion resistant polymer (Delrin®).
The 6mm front glass is made of highly fatigue resistant tempered glass. LED NAUTILUS is tested and can safely operate up to 150m depth.
ADDITIONAL PROTECTION AND STATUS SIGNALING
The electronic system controls the voltage level and signals low battery level with a strobe flash and automatically switches to back-up mode (light output at 20% light intensity) when the battery is drained.
LED NAUTILUS will only work in BACK-UP mode until the battery is recharged again.
