The Wurkkos HD50 4000 Lumen 239m Throw Rechargeable Headlamp with 21700 Battery is a versatile, professional-grade light designed for outdoor activities, ideal for camping, hiking, and repair tasks. For example, its 4000-lumen output can illuminate a path up to 239 meters, ensuring reliable visibility with spotlight, floodlight, and red light options. With built-in USB-C charging, a dual-switch interface, and a durable build, it offers practical functionality. Featuring a 1-year warranty, this Wurkkos HD50 for Outdoor Use suits campers, hikers, and outdoor enthusiasts.

Powerful Illumination for Outdoor Use
The Wurkkos HD50 features dual white LEDs (XHP50.3HI 5700-6000K and LH351D 5000K 90CRI) for spotlight and floodlight, along with a LATTICEPOWER XG 660nm red LED, delivering a maximum output of 4000 lumens with a beam throw of 239 meters. It is powered by an included 21700 Li-ion battery (5000mAh). It offers multiple modes, controlled by dual side switches, with the following lumen outputs and runtimes:

• Turbo (Spotlight + Floodlight): 4000 lumens for approximately 1 minute (steps down after initial output)
• High (Spotlight + Floodlight): 600 lumens for approximately 2 hours
• Medium (Spotlight + Floodlight): 150 lumens for approximately 6 hours
• Low (Spotlight + Floodlight): 10 lumens for approximately 24 hours
• Red Light: Intensity not specified (runtime not specified)
  The headlamp charges via a built-in USB-C port, taking about 5 hours with a 5V charger, and includes a power indicator (green for good charge, red for low, flashing red for critical). It has an IP67 waterproof rating, suitable for heavy rain, and features Advanced Temperature Regulation (ATR) technology, reducing brightness when the driver reaches 60°C, though prolonged use on high settings may generate heat, requiring careful handling.

Durable and Compact Design
The Wurkkos HD50 is constructed from aerospace-grade 6061 aluminum alloy with a Type III hard-anodized military-grade finish, offering durability for outdoor conditions like camping or hiking. It measures 86mm in length and 29.1mm in head diameter, weighing 100g without the battery (approximately 170g with the included 21700 battery and headband), making it suitable for headband or pocket use. The headlamp features a magnetic tail cap, a 180° tilting mechanism, and an adjustable headband, though its weight may require periodic adjustment during long wear.

Designed for Outdoor and Everyday Use
The Wurkkos HD50 4000 Lumen 239m Throw Rechargeable Headlamp with 21700 Battery for Outdoor Use is tailored for campers, hikers, and outdoor enthusiasts needing a reliable, hands-free light for nighttime activities, repairs, or emergencies. For example, its 24-hour low mode ensures prolonged runtime for extended trips, while the red light preserves night vision, though the dual-switch UI requires practice to cycle through modes (right switch for on/off, left switch for mode change, both for brightness adjustment), and the IP67 rating limits its use to surface-level water exposure. The USB-C charging and high CRI floodlight enhance its reliability, but users should avoid direct eye exposure due to its intensity. The HD50’s affordable price, included 21700 battery, and multifunctional design make it a practical choice for outdoor scenarios, offering a balance of power and convenience, though users should plan for heat management and switch familiarity.

• 1x 5000mAh 21700 Li-ion Battery
• Headband
• USB-A to USB-C Cable

Note: Ensure the headlamp is turned off or locked (fast four clicks on either switch to activate lockout mode) after use to prevent accidental activation, which could drain the battery; the dual switches can be sensitive. Use the included 21700 battery with proper polarity (positive terminal toward the head), and remove the insulating sticker before first use or charging. The IP67 rating protects against heavy rain but not submersion; avoid prolonged water exposure beyond splashes. 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 red light. Store in a dry place to maintain reliability, and use a 5V charger (not included) for optimal charging.
