The Sofirn HS45 is a high-performance rechargeable headlamp designed for users who need powerful illumination with better sustained-output performance. Delivering up to 3200 lumens and a maximum beam distance of 223 meters, the HS45 combines serious brightness with an innovative active fan cooling system that helps control heat and maintain higher output for longer.

Powered by a high-capacity 5500mAh 21700 rechargeable battery, the HS45 is built for hiking, camping, outdoor work, nighttime exploration, maintenance, and other activities where both brightness and runtime matter.

Active Fan Cooling – Stay Brighter for Longer

High-output headlamps generate significant heat, which often forces them to reduce brightness shortly after Turbo is activated.

The HS45 addresses this with an integrated active cooling fan.

By actively dissipating heat from the light, the cooling system helps the HS45 maintain stable high-output performance for longer compared with conventional passive-cooled designs.

For users who actually need sustained brightness—not just an impressive maximum-lumen figure—the active cooling system is one of the HS45's most distinctive features.

Up to 3200 Lumens

With a maximum output of 3200 lumens, the HS45 provides powerful illumination for demanding nighttime environments.

Its beam can reach up to 223 meters, giving it enough range for trail navigation, outdoor exploration, work sites, searching, and general long-distance visibility while still providing useful surrounding illumination.

For sustained high-output use, the HS45 can deliver approximately 1500 lumens for up to 2.5 hours, making it particularly useful when consistent illumination matters.

5500mAh 21700 Battery

The HS45 is powered by a high-capacity 5500mAh 21700 rechargeable Li-ion battery.

The large-capacity battery provides the energy required for both high-output operation and extended low-level runtime.

At the opposite end of its output range, Eco mode can provide up to approximately 210 hours of runtime, giving the HS45 the flexibility to handle everything from short high-intensity tasks to multi-day outdoor trips.

Headlamp + Right-Angle Flashlight

The HS45 isn't limited to head-mounted use.

Remove the light from its mounting bracket and it can function as a standalone right-angle flashlight, giving you more flexibility for handheld use, equipment inspection, maintenance, or close-range work.

This hybrid design effectively combines a high-performance headlamp and a versatile work light in one device.

Multiple Brightness Levels

The HS45 provides five lighting modes, allowing output to be adjusted according to the situation.

Lower settings are ideal for close-range tasks and extended runtime, while higher levels provide the illumination needed for trail navigation, outdoor work, and longer-distance visibility.

This broad output range allows the HS45 to transition easily between everyday tasks and demanding nighttime environments.

Simple One-Button Control

A single electronic switch controls power, brightness, and lighting modes.

The large, straightforward control is designed for easy operation, including when wearing gloves.

Instead of requiring multiple switches or complicated controls, the HS45 keeps essential functions accessible through one button.

Versatile 3-in-1 Mounting System

The HS45 provides multiple ways to position the light depending on the task.

Its mounting options include:

• Headlamp mounting for hands-free illumination

• Magnetic attachment to suitable metal surfaces

• Hook mounting for hanging the light

• Clip attachment for clothing or equipment

This versatility allows the HS45 to move beyond traditional headlamp use.

Wear it on your head while hiking, attach it to a backpack, hang it inside a tent, mount it to a suitable metal surface while working, or remove it completely and use it as a right-angle flashlight.

Magnetic Base for Hands-Free Work

The integrated magnetic base allows the HS45 to attach securely to suitable ferrous metal surfaces.

This is particularly useful for vehicle maintenance, repairs, workshops, equipment inspection, and other situations where you need both hands free.

Combined with the right-angle body, the magnetic mounting system makes the HS45 a capable portable work light as well as an outdoor headlamp.

Built for Demanding Nighttime Use

The combination of high output, extended battery capacity, active cooling, and flexible mounting makes the HS45 particularly suitable for users who spend extended periods working or moving outdoors after dark.

Rather than focusing only on short-duration Turbo performance, the HS45 is designed around practical sustained illumination.

Multiple Ways to Use One Light

The HS45 can adapt to different environments instead of functioning only as a conventional headlamp.

Hiking & Trail Use
Wear it as a headlamp for powerful hands-free illumination and long-distance visibility.

Camping
Use lower modes for extended runtime, or hang the light inside a tent or around camp.

Maintenance & Repairs
Remove it from the headband and attach the magnetic base to a suitable metal surface.

Outdoor Work
Use the active cooling system to help maintain stronger output during extended nighttime tasks.

Everyday Utility
Detach the light and carry it as a versatile right-angle flashlight when a headlamp isn't required.

More Than a 3200-Lumen Headlamp

Maximum brightness tells only part of the story.

The Sofirn HS45 combines 3200-lumen output, active fan cooling, a 5500mAh 21700 battery, 223-meter beam distance, and multiple mounting options to create a headlamp designed around practical sustained performance.

Wear it as a headlamp, detach it as a right-angle flashlight, mount it magnetically for hands-free work, or hang it where illumination is needed.

For users looking for powerful output without relying solely on short Turbo bursts, the HS45 offers a different approach: more effective thermal management, longer usable high output, and greater mounting versatility.
