Frequently Asked Questions

Q: How long does the ESMARTER rechargeable headlamp battery last on a single charge?

A: The built-in 18650 lithium-ion battery provides 2–4 hours of run time depending on the brightness mode selected. Low mode extends battery life, while High mode delivers maximum brightness for a shorter duration. A full charge takes approximately 3 hours via the included Micro USB cable.

Q: Is this COB LED headlamp waterproof for fishing and camping use?

Q: How does the motion sensor (induction) mode work?

A: Simply press the sensor key to activate the induction mode. In this mode, the headlamp detects motion near the sensor and toggles the light automatically — perfect for hands-free tasks when you can't reach the button, such as cooking at camp or handling fishing gear.

Q: Can the headlamp be tilted to direct the beam where I need it?

A: Yes. The lamp head adjusts up and down by 30° on its tilting base, allowing you to direct the COB LED beam precisely at your target — whether that's the ground ahead, a fishing line, or a campsite task at close range.
