RH4 headlamp is designed as a lightweight running headlamp.

It’s powered by a 1000 mAh lithium polymer battery pack.  3 x AAA alkaline batteries can be backup power for the headlamp.

The comfortable and skin-friendly headband is length adjustable to fit your head perfectly.

Adjustable lighting angles illuminate more broadly.

The fluorescence ring allows you to find the light easily in the dark.
