Its waterproof and rugged polycarbonate build means it can handle rainy, snowy, or rough conditions without failing, which is important for tough work environments.

The headlamp runs on 3 AAA batteries, which are included and last up to around 200 hours. The simple button control for switching modes is user-friendly, even if you’re not tech-savvy.
