The Wurkkos DL40 5000 Lumen 220m Throw Rechargeable Diving Flashlight with 26650 Battery is a professional-grade, robust light designed for underwater exploration and outdoor use, ideal for scuba diving, snorkeling, and emergency situations. For example, its 5000-lumen output can illuminate a path up to 220 meters, ensuring reliable visibility in challenging underwater environments. With a magnetic side switch interface and a durable build, it offers practical functionality. Featuring a 1-year warranty, this Wurkkos DL40 for Outdoor Use suits divers, adventurers, and outdoor enthusiasts.

Powerful Illumination for Outdoor Use

The Wurkkos DL40 features four Samsung LH351D LEDs with a 5000K color temperature and 90 CRI, delivering a maximum output of 5000 lumens with a beam throw of 220 meters, powered by two included 26650 Li-ion batteries (each rated at 5000mAh, with a real capacity of approximately 4800mAh). It offers multiple modes, controlled by a magnetic side switch, with the following lumen outputs and runtimes:

Turbo: 5000 lumens for approximately 3.5 hours
High: 2000 lumens for approximately 4 hours
Medium: 800 lumens for approximately 9 hours
Low: 300 lumens for approximately 28 hours
The flashlight does not have built-in charging and requires an external USB charger for the included batteries, with runtime estimates based on its use. It has an IPX8 waterproof rating, suitable for submersion up to 100 meters, and features Advanced Temperature Regulation (ATR) technology that adjusts brightness when the driver temperature reaches 50 C to prevent overheating, though prolonged use on Turbo may generate heat, requiring careful handling.
Durable and Compact Design

The Wurkkos DL40 is constructed from aerospace-grade 6061 aluminum alloy, CNC manufactured and hard-anodized to military-grade Type III specifications, offering durability and corrosion resistance for underwater and outdoor conditions like scuba diving or camping. It measures 201.1mm in length with a head diameter of 61mm, weighing 367.8g without the batteries (approximately 556g with the two included 26650 batteries), making it suitable for gear carry. The flashlight features a magnetic side switch, toughened mineral glass lens, and a padded lanyard ring, though its size may limit pocket portability.

Designed for Outdoor and Diving Use

The Wurkkos DL40 5000 Lumen 220m Throw Rechargeable Diving Flashlight with 26650 Battery for Outdoor Use is tailored for divers, adventurers, and outdoor enthusiasts needing a reliable light for underwater exploration, emergencies, or outdoor activities. For example, its 28-hour low mode ensures extended runtime for dives, while the IPX8 rating supports submersion up to 100 meters, though the magnetic switch UI requires practice to cycle through modes (click to cycle Low-Medium-High-Turbo), and the lack of built-in charging necessitates an external charger. The robust construction with double O-rings enhances its reliability, but users should avoid direct eye exposure due to its intensity and rinse it with fresh water after use to prevent corrosion. The DL40's affordable price, included 26650 batteries, and diving capability make it a practical choice for outdoor scenarios, offering a balance of power and convenience, though users should plan for heat management and charging logistics.

User Manual
Note: Ensure the flashlight is turned off after use to prevent accidental activation, which could drain the batteries; the magnetic side switch can be sensitive-ensure it is fully off when not in use. Use the included 26650 batteries with proper polarity (positive terminal toward the head), and remove the cardboard battery protection before first use or charging with the provided USB charger. The IPX8 rating supports submersion up to 100 meters but requires both ends to be fully screwed in with double O-rings secured; avoid prolonged submersion beyond this limit. Handle with care during Turbo mode to avoid burns due to heat buildup, and do not shine the light directly into eyes due to its intensity. Store in a dry place to maintain reliability, and use the provided USB charger for optimal performance. Rinse with fresh water after saltwater exposure to prevent corrosion, and replace worn-out O-rings with the spares provided to maintain waterproofness.
