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.
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.
Designed for Outdoor and Everyday Use
The Sofirn SP40 is tailored for campers, hikers, and DIY enthusiasts needing a reliable, hands-free light for nighttime activities, repairs, or emergencies. Its 220-hour low mode ensures prolonged runtime for extended trips, while the magnetic tail cap allows versatile positioning. The micro-USB charging and included accessories enhance its reliability, but users should avoid direct eye exposure due to its intensity.
