The Ferei W158II/W158BII CREE LED Diving Flashlight is a powerful, compact, and purpose-built underwater illumination tool designed for serious divers and underwater explorers. Its robust construction, high output, and exceptional depth rating make it a standout in the field of diving lights, particularly for those who frequently venture into tight underwater spaces such as wrecks, underwater caves, or areas near ship hulls and seafloors. Despite its relatively compact size, this flashlight delivers remarkable performance, blending durability, brightness, and functionality into one reliable tool that stands up to the most demanding underwater conditions.

At the heart of the W158II/W158BII is the CREE XHP50.2 LED, a highly efficient and robust light source that is renowned in the industry for its performance. This LED is capable of delivering a stunning 2060 lumens in the Cool White (CW) version and 1920 lumens in the Neutral White (NW) variant. The Cool White option provides a slightly bluer hue, ideal for cutting through murky water and enhancing contrast, while the Neutral White variant offers a warmer, more color-accurate beam that enhances visibility of natural underwater tones. With either option, the flashlight offers powerful illumination capable of penetrating through depths and darkness, ensuring maximum visibility and safety for the diver.

One of the most striking features of the W158II/W158BII is its depth rating. With a certified waterproof rating of IPX8 and the ability to withstand submersion up to 150 meters, this flashlight is well-suited for serious divers engaging in technical and recreational dives alike. Each unit is rigorously pressure and vibration tested prior to packaging, ensuring that it meets Ferei’s high standards for underwater reliability. This level of waterproofing, combined with its resistance to pressure changes, makes it ideal not just for shallow dives, but for more challenging expeditions as well.

Structurally, the flashlight is crafted from CNC-machined aerospace-grade aluminum alloy, which is treated with a Type III hard-anodized finish in black. This gives the flashlight excellent corrosion resistance, a key requirement for saltwater use, and ensures that it remains resilient against physical impact and abrasion. Its dimensions—210mm in length with a head diameter of 51mm and a body diameter of 27.5mm—strike a perfect balance between compactness and usability. It’s large enough to provide a secure grip even with gloved hands, yet compact enough to avoid unnecessary bulk, which is particularly important in confined underwater environments.

The flashlight operates using a sophisticated and intuitive magnetic rotary switch. Unlike traditional switches, this design has no internal mechanical connection, making it far more reliable in underwater environments where dirt, corrosion, or pressure could affect standard mechanisms. The rotary switch offers smooth, 360-degree control to turn the flashlight on or off and to toggle between different brightness settings, which include Max, Mid, Low, and SOS modes. An additional feature is the low battery warning function that begins blinking 20 to 30 minutes before power runs out, giving the diver ample time to exit safely.

Functionally, the flashlight uses a well-engineered aluminum alloy reflector coated with a high-temperature resistant reflective film. This enhances the light’s focus and luminous efficiency, allowing for a combined spotlight beam that delivers both reach and breadth. The clear optical lens, made from ultra-toughened glass, is equally suited to the job, providing excellent light transmission while resisting scratches and impact.

Powering the W158II/W158BII are two 18650 lithium-ion batteries, and the package includes two 3400mAh batteries from Ferei for long-lasting performance. The dual battery setup is accommodated by an extended frame, which adds to the flashlight's endurance without sacrificing its convenient form factor. On a full charge, the flashlight can run continuously at maximum brightness for up to 3.5 hours—an impressive achievement considering the output level. This extended runtime is especially useful for longer dives or when multiple dives are planned without access to charging facilities in between.

Charging the batteries is equally user-friendly, thanks to the included dual-bay dock charger and transformer. The charger is designed to accommodate the included 18650 batteries and ensures they are fully recharged in approximately six hours. The intelligent charging circuit also includes multiple safety features, such as over-discharge protection, polarity protection to guard against incorrect battery installation, and an integrated temperature control system. This system automatically regulates output if the internal temperature rises too high, maintaining a stable operating temperature and protecting both the user and the flashlight.

The Ferei W158II/W158BII is not just limited to underwater use; it also functions effectively as a general-purpose LED flashlight when used outside of water. Its high output, durability, and practical interface make it a great companion for hiking, caving, or any outdoor activity where reliability and brightness are key. However, it truly shines in underwater settings, where its design and performance features come together to meet the unique challenges of diving.

The full kit includes everything needed for immediate use: one W158II or W158BII diving light, one AC009B dock charger, one C28 battery holder, and two high-capacity 18650 batteries. This comprehensive kit ensures that divers are fully equipped from the moment they open the box, without needing to purchase additional accessories.

In conclusion, the Ferei W158II/W158BII is an exceptional diving flashlight that represents a perfect combination of form, function, and reliability. With its advanced CREE XHP50.2 LED, superior waterproofing, corrosion resistance, and intuitive magnetic switch, it stands out as a high-end tool for underwater professionals and serious enthusiasts alike. The powerful output, impressive runtime, and robust construction make it ideal for challenging dives in wrecks, caves, or deep-sea environments. Whether you’re a recreational diver looking for dependable illumination or a professional in need of a compact yet powerful diving light, the W158II/W158BII is a choice that delivers exceptional performance and peace of mind.
