FAQs
How long does the battery last on a single charge?
Battery life varies based on the brightness mode; however, the internal 640mAh battery is optimized for typical short-term outdoor activities.
Is this headlamp waterproof?
It has an IPX4 rating, which means it is resistant to splashing water from any direction but should not be submerged.
Can I use it for long-distance trail running at night?
While lightweight and comfortable, the 170-lumen output is best for close-range tasks; it may not provide enough throw for high-speed trail running in total darkness.
What type of cable do I need to charge it?
The headlamp supports standard USB Type-C charging.
What is the purpose of the red light mode?
The red light is designed to preserve your natural night vision and is less likely to attract insects than white light.
How do I toggle between light modes?
You can cycle through the high, low, red, and red strobe modes using the single control button on the unit.
Troubleshooting
Headlamp fails to turn on
Ensure the device has been charged for at least 2.5 hours and check the connection between the charging cable and the port.
Light dims during use
This is a sign of low battery. Connect the unit to a power source to restore full luminosity.
Charging port debris
Gently use a non-conductive tool or compressed air to clean any dirt or lint from the Type-C port.
Charging: Connect the headlamp to a standard USB power source using a compatible Type-C cable. The charging time is roughly 2.5 hours.
Operation: Use the integrated control button to cycle through the four available light modes.
Care: While the unit is IPX4 waterproof, it is not designed for submersion. Wipe the lens with a soft, dry cloth to ensure light clarity and store the device in a cool, dry place when not in use for extended periods.
Maintenance: Regularly check the charging port for debris and ensure the battery is charged at least once every few months to maintain cell health.
