The Sofirn SP40 1200 Lumen 136m Throw Rechargeable Headlamp with 18650 Battery is a versatile, lightweight light designed for outdoor activities, ideal for camping, hiking, and repair tasks. For example, its 1200-lumen output can illuminate a path up to 136 meters, ensuring reliable visibility. With built-in micro-USB charging, a side switch interface, and a durable build, it offers practical functionality. Featuring a 1-year warranty, this Sofirn SP40 for Outdoor Use suits campers, hikers, and DIY enthusiasts.

Powerful Illumination for Outdoor Use
The Sofirn SP40 features a Cree XP-L LED with a 5000-5700K color temperature, delivering a maximum output of 1200 lumens with a beam throw of 136 meters, powered by an included 18650 Li-ion battery (3000mAh). It offers multiple modes, controlled by a side switch, with the following lumen outputs and runtimes:

• Turbo: 1200 lumens for approximately 1 hour 50 minutes
• High: 400 lumens for approximately 3 hours
• Medium: 150 lumens for approximately 8 hours
• Low: 10 lumens for approximately 220 hours
  The headlamp charges via a built-in micro-USB port, taking about 5-6 hours with a 5V charger (not included), and includes a power indicator on the switch (green for over 30% charge, red for below 30%, flashing red for low power). It has an IPX7 water-resistant rating, suitable for heavy rain, and features Advanced Temperature Regulation (ATR) technology, adjusting brightness above 55°C to prevent overheating, though prolonged use on Turbo may generate heat, requiring careful handling.

Durable and Compact Design
The Sofirn SP40 is constructed from aerospace-grade 6061 aluminum alloy with a Type III hard-anodized finish, offering durability for outdoor conditions like camping or hiking. It measures 108mm in length with a head diameter of 25mm, weighing approximately 63g without the battery (around 93g with the included 18650 battery), making it comfortable for extended wear. The headlamp features a magnetic tail cap for hands-free use on metal surfaces, a detachable pocket clip, and an adjustable headband, though the clip’s placement may protrude slightly when mounted.

Designed for Outdoor and Everyday Use
The Sofirn SP40 1200 Lumen 136m Throw Rechargeable Headlamp with 18650 Battery for Outdoor Use is tailored for campers, hikers, and DIY enthusiasts needing a reliable, hands-free light for nighttime activities, repairs, or emergencies. For example, its 220-hour low mode ensures prolonged runtime for extended trips, while the magnetic tail cap allows versatile positioning, though the side switch UI requires practice to cycle through modes (single click to turn on/off, hold to adjust brightness levels, double-click for Turbo), and the IPX7 rating limits its use to surface-level water exposure. The micro-USB charging and included accessories enhance its reliability, but users should avoid direct eye exposure due to its intensity. The SP40’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 charging time and understand its water resistance limits.
