Sofirn HS21 2000lm USB C Headlamp SFT40 With Infrared Switch

The Sofirn HS21 headlamp is a purpose-built companion for outdoor explorers who demand clarity, reach, and flexibility from a single light. At its core sits 2000 lumens from a 10-emitter array, delivering a precise spotlight, a broad flood, and a subtle red night-vision option. A buck-driven driver keeps output stable, while the USB-C rechargeable battery system keeps you powered on longer trails.

What makes the HS21 uniquely capable

• Versatile triple output: Spotlight, floodlight, and red light in one compact headlamp. The spotlight and flood can run together for a balanced beam, ideal for navigation, campsite setup, and hands-on tasks. Ten emitters include 1 x SFT40 main beam, 6 x CSP1919 flood LEDs, and 3 x HFL1-R red LEDs for night vision without washing out your surroundings.
• Long reach meets practical brightness: The primary SFT40 LED (6000K–6500K) delivers up to 2000 lumens with a maximum throw of about 230 meters, while the buck driver maintains consistent brightness across battery levels.
• Hands-free brightness control: Wave your hand near the infrared sensor to adjust brightness on the fly—gloved hands or muddy fingers won’t slow you down.
• Intuitive, tactile controls: A robust rotary switch makes cycling through modes easy, even in low light or when wearing gloves. A dedicated infrared switch and a quick-access button add flexibility for quick brightness tweaks.
• USB-C power and easy topping up: Recharge via USB-C from a charger, power bank, or laptop. The cap can be unscrewed to replace the included 18650 battery, so you’re never left in the dark on multi-day adventures.

Build, durability, and design

Crafted from AL6061-T6 aluminum alloy, the HS21 balances rugged durability with lightweight ergonomics. Its compact dimensions (35.7 × 45.75 × 86.5 mm) and a featherweight 87 g (without battery) make it comfortable for long treks, night fishing, or cycling. The headlamp is designed to withstand outdoor conditions and its waterproof construction keeps performance reliable when the weather turns.

Battery, charging, and runtime tips

Each HS21 kit includes a 18650 battery, compatible with the headlamp’s 3–4.2 V operating range. USB-C charging enables fast top-ups from a wall charger, power bank, or laptop. For extended trips, you can swap the battery on the go by unscrewing the cap. Pro tips: use the red light mode for wildlife viewing or late-night campsite tasks to preserve your night vision, and keep the lens clean for maximum beam efficiency.

Who is it for and practical use cases

Designed for hunting, camping, hiking, fishing, and biking, the HS21 excels wherever you need reliable, versatile illumination. The ability to run spot and flood together eliminates the need for multiple lights, while the red night-vision LEDs help you observe wildlife or read maps without compromising your natural night adaptation. It’s equally at home on a trail at dusk, around a campsite after sundown, or during late-night outdoor chores requiring precise light without glare.

Why choose the Sofirn HS21 over other headlamps

Unlike single-beam solutions, the HS21 consolidates spotlight reach, broad flood coverage, and red-night vision into one compact unit. The combination of a dedicated infrared wave control, a dependable buck driver for stable brightness, and USB-C rechargeability makes this headlamp ready for real-world outdoor use. It’s not just bright—it’s thoughtfully engineered to adapt to your activity, climate, and hands-on tasks without switching devices.

Ready for any outdoor challenge, the Sofirn HS21 isn’t just a light—it’s a purpose-built companion that keeps pace with your adventures from first light to last trace of starlight.
