The Archon D10 II is a high-performance diving flashlight that embodies the essential qualities of power, durability, and reliability for both recreational and professional divers. Crafted for underwater adventures, this flashlight delivers an impressive maximum output of 2000 lumens, making it an ideal choice for illuminating the darkest depths of the ocean. With its precise 9° spotlight beam enhanced by peripheral illumination, the D10 II is engineered for optimal visibility in complex underwater environments such as caves, wrecks, reefs, and murky waters.

At the heart of the D10 II is a high-quality Luminus white CREE LED, offering a powerful beam with a color temperature of 6500K. This daylight-like beam is sharp and focused, yet supplemented with just the right amount of ambient spill to ensure full spatial awareness. Divers will appreciate the intense central hotspot, which provides superior penetration through water particles, ensuring clarity even in challenging diving conditions. This light is particularly useful for those who require precision visibility during technical dives, underwater photography, and marine wildlife exploration.

The flashlight's illumination system is supported by a glossy aluminum reflector, which efficiently channels the LED’s output into a tight beam. This precise optical engineering enhances the light’s ability to travel great distances underwater, where beam control is critical due to the way water absorbs and scatters light. With an operation beam angle of 9° plus peripheral lighting, the D10 II gives divers both a long throw and surrounding glow, balancing pinpoint targeting with necessary environmental context.

Powering the Archon D10 II is a robust 21700 lithium-ion rechargeable battery equipped with an integrated Battery Management System (BMS). This battery not only provides consistent power delivery but also features intelligent safeguards, including over-discharge protection and reverse polarity protection. These features are essential for preserving the integrity of both the battery and the flashlight, particularly in environments where replacing or troubleshooting equipment mid-dive is not feasible. Operating within a voltage range of 4.2V to 2.8V, the D10 II offers stable performance across varying battery levels.

When fully charged, the flashlight provides up to 3 hours of continuous runtime on high mode. For more extended dives or situations requiring prolonged use, the low mode offers up to 6 hours of light, while the strobe mode, useful for signaling or emergency scenarios, can operate for up to 8 hours. This combination of output levels makes the D10 II extremely versatile, allowing users to conserve energy when needed without sacrificing functionality. Switching between the modes is simple and intuitive, keeping the diver’s focus on the dive rather than the tool.

Structurally, the Archon D10 II is a masterpiece of durability and ergonomic design. Its body is constructed from hard-anodized aluminum—a material prized for its strength, corrosion resistance, and lightweight nature. The surface treatment further enhances the flashlight’s ability to resist the harsh conditions encountered in saltwater environments. Whether it’s scraping along rocky outcrops, being handled with thick gloves, or simply enduring the wear and tear of frequent dives, the D10 II is built to last.

The flashlight features a polycarbonate lens that is 8 mm thick. This lens is not only shatter-resistant but also pressure-resistant, enabling the flashlight to function at depths of up to 100 meters. This depth rating ensures that the D10 II is well-suited for recreational scuba diving as well as for advanced and technical diving missions. Divers operating in demanding conditions can trust the structural integrity of the lens to remain uncompromised, even during deep descents or rapid ascents.

Weighing approximately 240 grams without the battery and around 315 grams with the battery, the D10 II is notably lightweight for a flashlight of its capabilities. When submerged, its weight in water drops to approximately 135 grams, offering excellent balance and neutral buoyancy. This makes it easy to handle, carry, and maneuver underwater without causing fatigue or drag, an essential factor for maintaining agility and endurance during long dives.

Designed with user comfort in mind, the flashlight’s cylindrical body (measuring 159.6 mm in length and 27.5 mm in diameter) fits naturally in the hand. The head diameter of 50 mm houses the powerful LED and reflector system, while still maintaining a streamlined silhouette. This sleek, tactical form factor minimizes resistance in water, contributing to a smoother diving experience. The ergonomic design ensures a secure grip, whether handled directly or mounted onto diving gear via accessories.

The user interface of the D10 II is refreshingly straightforward, with an output cycle that includes high, low, and strobe modes. The simplicity of the interface is especially valuable when operating the flashlight in low-visibility environments or with thick gloves, as it reduces the chance of accidental activation or mode selection errors. Its practicality makes it a favorite among divers who value function over unnecessary complexity.

The flashlight is equipped with battery warning systems to keep the user informed about battery status. As the battery voltage begins to drop, the output adjusts accordingly to prevent sudden shutoffs, and the BMS intervenes if the battery approaches unsafe levels. These protections not only safeguard the flashlight but also enhance the diver’s safety by reducing the likelihood of unexpectedly losing illumination underwater.

In terms of accessories, the D10 II comes complete with a rechargeable 21700 battery and a charging cable, ensuring that divers have everything they need to power up the flashlight out of the box. This ready-to-use approach is ideal for both new users and experienced divers who appreciate convenience and reliability.

With an IPX8 waterproof rating, the Archon D10 II meets the most rigorous standards for submersion. This rating certifies the flashlight for continuous operation underwater, up to the stated depth of 100 meters. Combined with its impact resistance and solid construction, the D10 II stands out as one of the most trustworthy tools a diver can carry.

In conclusion, the Archon D10 II is a well-engineered, high-output diving flashlight that meets the demands of both professionals and enthusiasts. With its powerful LED, precision reflector, and versatile operating modes, it delivers excellent performance in a compact and durable form. Its waterproof capabilities, long battery life, and reliable construction make it an invaluable asset for any underwater explorer. Whether you're navigating through a wreck, searching the seafloor, or signaling to a dive buddy, the D10 II offers the performance and peace of mind you need below the surface.
