Breakthrough Efficiency & Performance

Maximum brightness with optimized power consumption.m

3200 Lumens & 92,000 Lux Powerhouse

Engineered with the high-efficiency LUMINUS SFT-70.2 LED, the Nautilus MKII delivers exceptional light penetration while extending battery runtime.

  • Unmatched Intensity: Generates an incredible 92,000 Lux at 1 meter, ensuring bright, clear illumination at extreme depths.
  • Low Power Draw: Consumes only 30 W, maximizing your total burn time on every canister battery.
  • Unicase Thermal Management: Built from hard-anodized aluminum and DELRIN®, the monolithic body effectively dissipates heat to maintain peak LED output.
  • Depth-Tested: Precision-engineered and pressure-tested to withstand harsh environments down to 150 meters.

Variable Beam Angle Optics

Advanced Fresnel lens technology for total beam control.

Adjustable Focus from 4.7° to 60°

The LED NAUTILUS MKII gives you complete control over your lighting field in any underwater scenario. Seamlessly transition from a razor-sharp spot to a wide floodlight.

  • Penetrating Spot (4.7°): An ultra-focused beam engineered for long-range signaling and cutting through dense silt or murky water.
  • Wide Flood (60°): A smooth, even beam that fills your entire field of view, perfect for illuminating large cave chambers, wrecks, or wide-angle video work.
  • Upgraded Magnetic Clutch: Features a redesigned zoom ring with tactile feedback, allowing smooth focus adjustments even when wearing thick drysuit gloves.

Upgraded Magnetic Focus Control

Effortless beam adjustment under any diving conditions.

Precise Adjustments Even in Thick Gloves

The redesigned magnetic clutch mechanism provides smooth, positive engagement with distinct tactile feedback. Focus adjustment requires minimal effort and remains completely reliable under cold-water conditions, even when wearing heavy drysuit gloves.

  • Tactile Engagement: Definitive click feel gives instant feedback on beam width adjustments without looking at the head.
  • Drysuit Glove Friendly: Engineered ring resistance allows easy one-handed operation even with 3-finger neoprene or dry gloves.
  • Contactless System: Magnetic operation eliminates mechanical seals through the casing, maximizing waterproof integrity.

Unicase Cooling & Heavy-Duty Build

Rugged construction engineered for extreme environments.

Hard-Anodized Aluminum & Delrin®

Machined from a monolithic block of aircraft-grade aluminum combined with durable Delrin®, the Unicase housing acts as an efficient heatsink. This passive thermal management keeps internal components cool, extending the lifespan of the LED and ensuring stable, maximum output down to a depth of 150 meters.

  • Passive Heat Dissipation: Monolithic Unicase design transfers LED heat directly into the water to preserve performance.
  • Hard-Anodized Protection: Provides maximum resistance against saltwater corrosion, impact, and harsh cave environments.
  • 150 m Depth Rating: Solid Delrin® and heavy-duty glass construction ensure full reliability during extreme deep dives.

Optimized Balance & Lightweight Ergonomics

Superior comfort for long exploration dives.

Only 366 g Head Weight

Designed with underwater trim in mind, the Nautilus MKII weighs only 366 g in air. Its redesigned, compact body profile ensures perfect balance when mounted on a Goodman handle, drastically reducing hand and wrist strain during long explorations.

  • Featherlight Handling: At just 366 g, it minimizes wrist fatigue during extended bottom times.
  • Goodman Handle Harmony: Optimized center of gravity prevents the light head from tilting or twisting on your hand.
  • Streamlined Profile: Compact 140 mm body length easily maneuvers through tight restrictions and tight cave passages.

Greater Safety with Status Signaling

Never be left in the dark.

Guaranteed Light When You Need It Most

Integrated microcontroller systems actively monitor battery levels to ensure you are never left in the dark during critical exploration.

  • Low Battery Flash: Alerts you with a clear strobe warning signal as battery capacity drops to critical levels.
  • "Take Me Home" Reserve: Automatically switches to an ultra-efficient low-power mode, granting essential extra runtime to exit safely.
  • Optimum Balance: Weighing just 366 g with an optimized body profile, it reduces hand fatigue when mounted on a Goodman handle.

Everything You Need for Professional Exploration
