Wurkkos HD20 21700 Headlamp

The Wurkkos HD20 Headlamp is a high-performance, dual-emitter lighting solution engineered for professionals and outdoor enthusiasts who demand reliability, brightness, and versatility. Designed for use in demanding environments, it excels in camping, hiking, fishing and other outdoor activities where consistent, powerful illumination is essential. The HD20 can be used as a handheld flashlight, a tool lamp, or securely mounted as a headlamp using the included adjustable headband—making it a true multi-role lighting tool.

At the heart of the HD20 is a dual-LED system combining a Samsung LH351D with 90 CRI for superior color accuracy in floodlight mode and a Cree XP-L HD LED with 70 CRI for a focused, long-range spotlight. This combination delivers up to 2000 lumens in spot mode, with excellent beam control and minimal color distortion. The 90 CRI floodlight ensures accurate color rendering at close range, which is particularly useful for tasks like reading maps, setting up camp, or inspecting gear in low light.

The flashlight’s body is precision-crafted from aerospace-grade 6061 aluminum alloy, CNC machined and hard-anodized to Type III military specifications. This ensures exceptional durability, resistance to abrasion, and effective heat dissipation—critical for extended use. The anti-crash geometry and rugged construction mean the HD20 can survive drops, impacts, and harsh weather conditions without compromising performance.

Equipped with an advanced Temperature Regulation (ATR) system, the HD20 automatically reduces output when internal temperatures reach 60°C, preventing overheating and extending the lifespan of the LEDs. This intelligent thermal management ensures consistent performance even during prolonged use. A low voltage warning alerts users when the battery is running low, helping avoid unexpected power loss during critical moments.

The magnetic tailcap adds convenience, allowing the lamp to be securely attached to metal surfaces—ideal for hands-free operation during repairs, camping setup, or emergency situations. The USB-C charging port supports both Type A-C and Type C-C cables, offering flexible charging options. A red flashing LED indicates charging, turning solid green when fully charged. The HD20 also functions as a power bank, capable of charging external USB devices such as phones or GPS units—perfect for remote expeditions.

With an IP-68 waterproof rating, the HD20 is fully sealed against dust and can be submerged up to 2 meters for 30 minutes, making it suitable for use in rain, snow, or even accidental immersion. Reverse polarity protection safeguards the device if the battery is inserted incorrectly, adding another layer of user safety.

Despite its robust build, the HD20 weighs just 130g without a battery, making it a manageable choice for headlamp use. While it is heavier than most headlights, the trade-off is in extended runtime and superior performance. The included adapter sleeve allows the use of a single 18650 battery, providing flexibility in power sourcing.
