FAQ

Is this headlamp suitable for outdoor work?

Yes, the lamp has an IP44 degree of protection, so it is suitable for outdoor use in humid conditions or where water splashes may occur. However, it is not intended for immersion in water or long-term use in very heavy rain.

How long does the lamp work when fully charged?

The maximum operating time can reach up to 30 hours, depending on the selected lighting mode. When using 100% brightness, the battery will discharge faster, while using the 10% mode will allow much longer operation.

Can the light direction be adjusted?

Yes, the front part of the lamp can be tilted, so the light can be directed to the required work area. This is convenient when working in electrical panels, repairing a car or moving in a dark environment.

What is the rear red light used for?

The rear red light increases the user’s visibility from behind. It is especially useful when running, walking along the roadside, working outdoors or moving in the dark.
