For example, its 2000-lumen output can illuminate a path up to 300 meters, ensuring reliable visibility in underwater environments. With a magnetic side switch interface and a durable build, it offers practical functionality. Featuring a 1-year warranty, this Wurkkos WK20S for Outdoor Use suits divers, adventurers, and outdoor enthusiasts.

Powerful Illumination for Outdoor Use

The Wurkkos WK20S features a Luminus SST40 HD LED with a 5000K color temperature and 90 CRI, delivering a maximum output of 2000 lumens with a beam throw of 300 meters, powered by an included 18650 Li-ion battery (3000mAh). It offers multiple modes, controlled by a magnetic side switch, with the following lumen outputs and runtimes:

High: 2000 lumens for approximately 2 hours
Medium: 800 lumens for approximately 5 hours
Low: 200 lumens for approximately 10 hours
Eco: 50 lumens for approximately 20 hours
The flashlight does not have built-in charging and requires an external charger for the included 18650 battery, with runtime estimates based on its use. It has an IPX8 waterproof rating, suitable for submersion up to 100 meters, and features a sealed design to withstand high water pressure, though prolonged use on high settings may generate heat, requiring careful handling.
Durable and Compact Design

The Wurkkos WK20S is constructed from 6061 aircraft-grade aluminum alloy with a Type III hard-anodized, anti-abrasive finish, offering durability and corrosion resistance for underwater and outdoor conditions like scuba diving or trekking. It measures approximately 162.5mm in length with a head diameter of 28.5mm, weighing 84g without the battery (approximately 114g with the included 18650 battery), making it suitable for gear carry. The flashlight features a magnetic side switch, double rubber sealing rings, and a lanyard attachment, though its length may limit pocket portability.

Designed for Outdoor and Diving Use

The Wurkkos WK20S 2000 Lumen 300m Throw Rechargeable Diving Flashlight with 18650 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 20-hour Eco 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 (one click to turn on or cycle through Eco, Low, Medium, High), 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 WK20S's affordable price, included 18650 battery, 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 battery; the magnetic side switch can be sensitive-ensure it is fully off when not in use. Use the included 18650 battery with proper polarity (positive terminal toward the head), and remove the insulating film before first use or charging with an external charger (not included). 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 High 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 a compatible charger for the 18650 battery. Rinse with fresh water after saltwater exposure to prevent corrosion.
