The Sofirn HS42 2100 Lumen 176m Throw Rechargeable Headlamp with 18650 Battery is a versatile, lightweight light designed for outdoor activities, ideal for camping, hiking, and professional tasks. For example, its 2100-lumen output can illuminate a path up to 176 meters, ensuring reliable visibility with its multi-light sources. With built-in USB-C charging, a side e-switch interface, and a durable build, it offers practical functionality. Featuring a 1-year warranty, this Sofirn HS42 for Outdoor Use suits campers, hikers, and outdoor enthusiasts.

Powerful Illumination for Outdoor Use
The Sofirn HS42 features a combination of six LEDs: one SST-40 6000K LED for spotlight, three CSP2323 5000K 90CRI LEDs for floodlight, and two HFL1-R red LEDs, delivering a maximum output of 2100 lumens with a beam throw of 176 meters. It is powered by an included 18650 Li-ion battery (3000mAh). It offers multiple modes, controlled by a side e-switch, with the following lumen outputs and runtimes:

• Turbo: 2100 lumens for approximately 2 hours
• High: 1000 lumens for approximately 3 hours
• Medium: 400 lumens for approximately 6 hours
• Low: 100 lumens for approximately 12 hours
• Red Light: Intensity not specified (runtime not specified)
  The headlamp charges via a built-in USB-C port, taking about 2 hours 10 minutes with a 5V/2A charger, and includes an indicator LED under the switch (green for 70-100% power, red for 30-69%, flashing red for below 30%). It has an IPX8 waterproof rating (suitable for submersion up to 2 meters), and features Advanced Temperature Regulation (ATR) technology, reducing output when the temperature reaches 55°C, though prolonged use on high settings may generate heat, requiring careful handling.

Durable and Compact Design
The Sofirn HS42 is constructed from AL6061-T6 aluminum alloy with a Type III hard-anodized finish, offering durability for outdoor conditions like camping or hiking. It measures 112mm in length, 27.2mm in head width, and 26mm in body diameter, weighing 71g without the battery (approximately 101g with the included 18650 battery), making it comfortable for extended wear. The headlamp features a magnetic tailcap, a knurled side e-switch, and an adjustable headband with a tiltable design up to 180°, though the magnetic tailcap may limit flat tailstanding with a lanyard attached.

Designed for Outdoor and Everyday Use
The Sofirn HS42 2100 Lumen 176m Throw Rechargeable Headlamp with 18650 Battery for Outdoor Use is tailored for campers, hikers, and outdoor enthusiasts needing a reliable, hands-free light for nighttime activities, emergencies, or professional tasks. For example, its 12-hour low mode ensures prolonged runtime for overnight trips, while the red light mode preserves night vision, though the side e-switch UI requires practice to cycle through modes (click to turn on/off, hold to adjust brightness, double-click for strobe, triple-click to switch channels), and the magnetic tailcap allows versatile mounting but may not suit all surfaces. The USB-C charging and multi-channel design enhance its reliability, but users should avoid direct eye exposure due to its intensity. The HS42’s affordable price, included 18650 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 UI familiarity.

Note: Ensure the headlamp is turned off after use to prevent accidental activation, which could drain the battery; the side e-switch can be sensitive. Use the included 18650 battery with proper polarity (positive terminal toward the head), and remove the insulating film before first use or charging. The IPX8 rating protects against submersion up to 2 meters but is not suitable for diving; avoid prolonged deep submersion. 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 a 5V/2A charger (not included) for optimal charging. The magnetic tailcap allows attachment to metal surfaces but may affect tailstanding stability with a lanyard.
