The Sofirn SP40 1200 Lumen 136m Throw Rechargeable Headlamp with 18650 Battery is a versatile, lightweight light designed for everyday carry and outdoor use, ideal for running, hiking, and emergency situations. For example, its 1200-lumen output can illuminate a path up to 136 meters, ensuring reliable visibility with a wide beam profile. With built-in micro-USB charging, a side e-switch interface, and a durable build, it offers practical functionality. Featuring a 1-year warranty, this Sofirn SP40 for Outdoor Use suits outdoor enthusiasts, runners, and EDC users.
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 e-switch, with the following lumen outputs and runtimes:
Turbo: 1200 lumens for approximately 1 hour 50 minutes
High: 400 lumens for approximately 4 hours
Medium: 100 lumens for approximately 12 hours
Low: 5 lumens for approximately 220 hours
The flashlight charges via a built-in micro-USB port, taking about 3-4 hours with a 5V charger, and includes a charging indicator (red during charging, green when full). It has an IPX7 waterproof rating, suitable for submersion up to 1 meter for 30 minutes, and features Advanced Temperature Regulation (ATR) technology, adjusting brightness when the driver temperature reaches 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 and corrosion resistance for outdoor conditions like running or hiking. It measures 108mm in length with a head diameter of 25mm, weighing 63g without the battery (approximately 93g with the included 18650 battery), making it suitable for pocket or headband use. The flashlight features a magnetic tailcap, a removable headband, and an included clip, though the clip attachment may limit tailstanding stability.
Designed for Outdoor and Everyday Use
The Sofirn SP40 1200 Lumen 136m Throw Rechargeable Headlamp with 18650 Battery for Outdoor Use is tailored for outdoor enthusiasts, runners, and EDC users needing a reliable, portable light for daily activities, emergencies, or outdoor adventures. For example, its 220-hour low mode ensures extended runtime for overnight use, while the magnetic tailcap allows hands-free mounting on metal surfaces, though the side e-switch UI requires practice to cycle through modes (short click to turn on/off, hold to cycle Low-Medium-High, double-click for Turbo), and the IPX7 rating limits its use to shallow submersion. The micro-USB charging enhances its reliability, but users should avoid direct eye exposure due to its intensity and rinse it with fresh water after use to maintain performance. The SP40's affordable price, included 18650 battery, and multi-functional 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.

User Manual
Note: Ensure the flashlight is turned off or locked (four quick clicks to activate lockout mode) 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 IPX7 rating supports submersion up to 1 meter for 30 minutes; avoid prolonged submersion beyond this limit. 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 charger (not included) for optimal charging. Unscrew the tailcap half a turn during storage to prevent self-discharge.
