The Algo is a headlamp with the latest C4 LED in the light source.
The brightness can be switched between 3 levels (3 ranges, high, middle, low).
You can also check the battery consumption status with the built-in power indicator.
In addition to the standard strap, it also comes with a rubber strap that is convenient when using a helmet. The body has a splash-proof structure and a tilt function that allows you to adjust the angle of the light by 90 degrees.
