The Wurkkos DL03 2800 Lumen 480m Throw Rechargeable Diving Flashlight with 21700 Battery is a compact, multifunctional light designed for underwater use, ideal for scuba diving, underwater signaling, and emergency tasks. For example, its 2800-lumen output can illuminate a path up to 480 meters underwater, ensuring reliable visibility, while its green laser enhances navigation. With a side button switch interface, a robust build, and built-in USB-C charging, it offers practical functionality. Featuring a 1-year warranty, this Wurkkos DL03 for Outdoor Use suits divers and underwater enthusiasts.

Powerful Illumination for Outdoor Use
The Wurkkos DL03 features a LUMINUS SFT70 LED with a color temperature of 6000-6500K and a 520nm green laser, delivering a maximum output of 2800 lumens with a beam throw of 480 meters for the white light. It is powered by an included 21700 Li-ion battery (5000mAh). It offers multiple modes, controlled by a side button switch, with the following lumen outputs and runtimes:

• Turbo: 2800 lumens for approximately 2 minutes (steps down to 1800-1000 lumens, total runtime around 80 minutes)
• High: 1000 lumens for approximately 1 hour
• Medium: 300 lumens for approximately 2 hours
• Low: 100 lumens for approximately 6 hours
  The flashlight charges via a built-in USB-C port, taking about 2 hours with a 5V/1A charger, and includes a power indicator that flashes red during charging and turns solid green when full. It is IP68 waterproof (suitable for depths up to 100 meters) and features Advanced Temperature Regulation (ATR) technology, reducing brightness when the driver temperature reaches 60°C, though it may warm up during extended use, requiring careful handling.

Durable and Compact Design
The Wurkkos DL03 is constructed from aerospace-grade 6061 aluminum alloy with a Type III hard-anodized finish, offering durability and corrosion resistance for underwater conditions like scuba diving or signaling. It measures 148.5mm in length (5.85 inches) with a head diameter of 36mm (1.42 inches), weighing 152g without the battery (approximately 202g with the included 21700 battery), making it portable for dive gear. The flashlight features a tempered mineral glass lens, a side button switch, and a coiled lanyard for added security, though its size requires secure attachment to avoid loss underwater.

Designed for Outdoor and Diving Use
The Wurkkos DL03 2800 Lumen 480m Throw Rechargeable Diving Flashlight with 21700 Battery for Outdoor Use is tailored for divers and underwater enthusiasts needing a reliable, dual-function light for diving, signaling, or emergency underwater tasks. For example, its green laser penetrates murky waters for navigation or marking, while the 6-hour low mode ensures extended use for exploration, though the side button switch UI requires practice to toggle between white light and laser (double-click for Turbo), and the lack of a lockout function necessitates unscrewing the tailcap to prevent accidental activation. 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 maintain performance. The DL03’s affordable price, included battery, and versatile design make it a practical choice for underwater scenarios, offering a balance of power and convenience, though users should plan for switch familiarity and post-dive maintenance.

• Wurkkos DL03 Flashlight
• 1x 5000mAh 21700 Li-ion Battery
• Coiled Lanyard
• 2x O-Rings
• User Manual

Note: Ensure the flashlight is turned off or locked (unscrew the tailcap slightly) after use to prevent accidental activation, which could drain the battery; the side button switch can be sensitive. Use the included 21700 battery with proper polarity (positive terminal toward the head), and remove the insulating disc before first use. The IP68 rating supports submersion up to 100 meters, but clean with fresh water and lubricate O-rings after each dive to maintain waterproofing. 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, especially with the laser. Store in a dry place to maintain reliability, and avoid exposing the switch to sand or debris.
