The Ferei W168 Shark diving flashlight stands at the apex of performance and innovation in the world of underwater illumination. Designed to meet the rigorous demands of professional divers, technical explorers, and underwater photographers, this formidable lighting tool represents the pinnacle of power, reliability, and versatility. Crafted with premium materials and packed with advanced features, the W168 Shark is more than just a dive light — it is a fully integrated underwater searchlight system, ideal for high-risk underwater operations, shipwreck explorations, night diving, deep-sea excursions, and emergency rescue missions.

At the heart of the W168 Shark’s impressive performance lies a trio of CREE XHP70 LEDs, capable of delivering a staggering maximum output of 10,000 lumens. This immense light intensity transforms dark aquatic landscapes into brightly lit environments, providing unparalleled visibility even in the most challenging and light-deprived underwater settings. With a beam color set to cool white and a color temperature ranging between 5000K and 6800K, the light output ensures crisp detail recognition and strong color fidelity — essential attributes for underwater photography and observation. The beam itself is concentrated into a 15-degree focused angle, allowing divers to pierce through murky waters and observe details at astonishing distances. With a peak beam intensity of 168,921 candela and a throw that extends up to 822 meters, the W168 Shark ensures that no detail goes unnoticed, whether you're exploring the remains of a sunken vessel or scanning reef walls.

Equally impressive is the flashlight’s build quality and structural integrity. Constructed from aircraft-grade hard-anodized aluminum, the body of the W168 Shark is exceptionally robust, resistant to corrosion, impact, and high pressure. Its lenses, dual-coated with anti-reflective treatment, are engineered to withstand immense underwater pressures while delivering the highest levels of light transmission and clarity. Every inch of this light has been meticulously crafted for endurance, and the result is a device rated IPX8, submersible to depths of 150 meters. Whether you're navigating underwater caves or diving in unpredictable ocean currents, you can rely on this torch to perform without fail.

The Ferei W168 Shark has been designed with professional divers and underwater technicians in mind. One of its most innovative features is the isolated, waterproof, and directly rechargeable battery system that is seamlessly integrated into the body of the flashlight. This design not only enhances the overall compactness of the light but also reduces bulk and eliminates the need for external battery compartments or unwieldy connectors. The internal power source consists of a custom-built 8 x 18650 lithium battery pack, providing vast energy reserves and ensuring an ultra-long runtime. At maximum brightness, the light runs for approximately 3.4 hours, while on its lowest 2000-lumen setting, the runtime extends up to 15 hours. This extraordinary energy efficiency makes the W168 Shark ideal for long technical dives, cave dives, or extended night diving sessions where a dependable and enduring light source is critical.

Operating the W168 Shark is a seamless and intuitive experience thanks to its smart control system. The flashlight is equipped with four user-selectable brightness modes — Max, Mid, Min, and Flash — to adapt to various scenarios. Whether you need full brightness to illuminate a massive chamber or a softer beam for close-up tasks, the light offers the necessary flexibility. Control is handled via a well-engineered inverted tail switch that incorporates a magnetic rotary mechanism. Unlike conventional switches that rely on mechanical contact, the magnetic system ensures waterproof integrity and long-term reliability by eliminating the possibility of internal corrosion or mechanical failure. The switch also includes a thoughtfully designed hanging hole for attaching ropes or lanyards — a practical addition for divers who may wish to secure the light to their equipment.

Another standout feature of the W168 Shark is its intelligent circuit and temperature regulation system. This internal safeguard monitors temperature levels during operation and automatically adjusts the output to prevent overheating — a vital feature when dealing with high-lumen outputs over extended periods. Additionally, the circuit includes protection against over-discharge and reversed battery polarity, significantly enhancing the flashlight’s overall safety and lifespan. For added user convenience, a low battery warning system is also included. When battery levels drop below a critical threshold, the flashlight emits a blinking signal 20 to 30 minutes before shutdown, giving divers enough time to ascend or swap out equipment.

The practical features continue with the light's aluminum handle, which comes equipped with pre-drilled mounting holes compatible with GoPro mounts and other photographic accessories. This makes the W168 Shark not only a powerful illumination tool but also a key component of underwater photography and videography setups. The handle can also be fixed to brackets for use as a stationary light source or worn with a strap or belt for hands-free operation. If preferred, the handle can be removed entirely, converting the W168 into a more traditional long-range handheld flashlight. This modularity adds yet another layer of versatility, allowing the W168 to fulfill multiple roles across different environments and applications.

Charging the flashlight is as simple and efficient as its use. The package includes an AC007 charger that fully replenishes the internal battery pack in about five hours. This rapid recharge time, when considered alongside the light's extensive runtime and immense output, makes the W168 Shark a supremely practical option for divers and professionals who require quick turnaround times between dives or missions.

Despite its high power and rugged build, the flashlight remains impressively compact and well-balanced. Measuring 240mm in length and weighing just over 1.2 kilograms including batteries, the W168 manages to provide powerhouse performance in a manageable, ergonomic form factor. Its design prioritizes user comfort and efficiency, minimizing fatigue even during prolonged use in challenging conditions.

In conclusion, the Ferei W168 Shark diving flashlight is an elite-level tool purpose-built for those who demand the absolute best in underwater illumination. Whether you're a technical diver, rescue operator, underwater photographer, or adventurer exploring the ocean’s depths, the W168 offers unmatched brightness, range, durability, and convenience. With its combination of intelligent design, rugged construction, modular functionality, and extraordinary performance, this flashlight redefines the standard for what a professional diving light should be. It is not just a tool—it is a reliable partner beneath the waves, ready to shine light in the darkest places where clarity and precision are most needed.
