400 lumens80 m beamInfrared sensorIP44

The Brennenstuhl LuxPremium SL 401 AF is a rechargeable outdoor LED head torch combining a 400 lumen OSRAM LED with manual controls and an infrared sensor for contactless switching. It offers adjustable focus, multiple white and red lighting modes, an 80 metre maximum beam range and a rear red safety light, making it suitable for hiking, running, maintenance and hands-free work.

Outdoor use & charging:
The SL 401 AF carries an IP44 rating for protection against solid foreign objects and splash water from all directions. The rechargeable 18650 lithium-ion battery is replaceable, and charging is through the supplied USB-C cable. A USB power adapter is not listed as part of the package.

Best For

✓ Hiking, walking and running after dark
✓ Hands-free maintenance and assembly work
✓ Outdoor jobs where splash protection is required
✓ Situations where touch-free switching is useful

Key Features

 
400 lumen OSRAM LED
The main headlight delivers up to 400 lumens with a manufacturer-specified beam range of up to 80 metres. The light output uses a cool 6500 K colour temperature.
 
Touch-free infrared sensor
Two operating modes provide conventional manual control or infrared sensor operation, allowing the lamp to be switched without touching it when your hands are occupied or you are wearing gloves.
 
Multiple front and rear light modes
The front light provides 100%, 40% and 10% brightness levels, SOS and red light. A rear-facing light adds steady red and flashing red modes for better visibility from behind.
 
Adjustable focus and tilt
Stepless focus lets you change from a broad close-range beam to a concentrated long-distance beam, while the adjustable lamp angle directs light where it is needed.

Frequently Asked Questions

How bright is the SL 401 AF?
The main OSRAM LED produces up to 400 lumens, with Brennenstuhl specifying a maximum beam range of 80 metres.
What does the infrared sensor do?
Sensor mode allows contactless switching by hand movement, useful when wearing gloves or when touching the lamp would be inconvenient.
Is the battery replaceable?
Yes. Brennenstuhl specifies a replaceable 3.7 V, 2.6 Ah 18650 lithium-ion battery with a charge indicator.
Can it be used outdoors?
Yes. The head torch is IP44 rated and Brennenstuhl lists it as suitable for outdoor use, including activities such as hiking, jogging and assembly work.
Singular Expert Insight
The SL 401 AF is more versatile than a basic head torch because it combines a focused 400 lumen white beam with red front and rear lighting, adjustable focus and touch-free sensor operation. The battery pack sits at the rear of the head to distribute weight more evenly, and the battery itself is replaceable rather than permanently sealed into the lamp. For outdoor use, the IP44 rating provides splash protection, while the 80 metre beam and adjustable angle make the lamp useful both for close work and longer-distance visibility.

Buyer’s Guide

Buy it if

You want a rechargeable outdoor head torch with 400 lumens, sensor operation, adjustable focus and both white and red lighting modes.

Check first

IP44 protects against splash water but does not make the lamp waterproof for immersion. Choose a higher ingress-protection rating if your use requires stronger water protection.

Good to know

The supplied USB-C cable charges the replaceable 2.6 Ah battery in approximately four hours, with runtime reaching up to 50 hours depending on the selected mode.
