The Headlamp You Control With a Wave
Every other headlamp makes you find a button in the dark, often with cold or gloved fingers, sometimes while balancing something in your other hand. The motion sensor removes that entirely. One wave and you have light; one wave and it is off. Once you have used it, going back to a button-only lamp feels like a step backward.
Where hands-free wins
| Situation | Why the sensor helps |
|---|---|
| Carrying gear to the tent | Light on without putting anything down |
| Under the car or sink | Toggle with greasy or wet hands |
| Fishing at night | Light the line while both hands work |
| Walking the dog | Leash in one hand, wave with the other |
Sensor range is a short wave in front of the lamp; a button lets you disable it when you want.
Sensor, USB-C and IPX4 in one lamp

Motion-sensor headlamp FAQ
How does a motion-sensor headlamp work?
A small infrared sensor sits beside the LEDs. With sensor mode on, you wave a hand a few inches in front of the lamp and it switches on or off — no button to find. It is the fastest way to control a light when your hands are gloved, greasy or full, which is exactly when you need light most.
Can I turn the sensor off?
Yes. A physical button lets you run the light in normal mode without the sensor, so an accidental wave near your face while working close-up will not toggle it. Turn the sensor back on any time you want true hands-free control.
Is the sensor reliable outdoors?
The wave sensor works by reflecting infrared off your hand, so it responds consistently in the dark, in the cold and with gloves on. Because the lamp is IPX4 water-resistant, rain and splashes will not stop it either.
How is it powered and charged?
A built-in battery recharges over USB-C with the included cable — no disposable AAA cells. A small indicator glows red while charging and green when full. Runtime is roughly 4–6 hours per charge depending on the mode you use.
