Technical Information

The ONNIGHT 100 headlamp has 3 modes suited to every situation: - Red mode to remain discreet when hiding or maintaining night vision- Eco mode when walking or in the bivouac - Strong mode when hiking on paths
Operates with 3 LR03-AAA batteries (supplied)
The wide beam of the ONNIGHT 100 headlamp allows the light to spread uniformly to be able to see in front and to the sides
Classic LED lighting: lighting provisions gradually fade where batteries are low on charge in order to save power.
One-piece construction for excellent compactness. The flexible SEBS casing provides simple access to the batteries whilst protecting the headlamp from impact and rain. The ONNIGHT 100 switch is designed to be easy to handle with mittens on whilst avoiding random lighting when in your bag.
