This product is for…

Trail and ultra runners who run in the dark and want better ground-level illumination than a headlamp alone provides. Particularly suits those prone to headlamp headaches or who run in foggy conditions.

Worth noting…

Uses 18650 rechargeable batteries; highest brightness lasts ~4 hours, so carrying spares is recommended. Reversing the battery switches it to a red light mode — a non-obvious but useful feature.
