Designed with two distinct light sources to suit different uses. The first is a powerful CREE LED for long range / torch style illumination when hiking or searching etc. The large COB LED provides you a broad flood-style light which is perfect for more general illumination. Red and green LEDs are especially useful in adverse conditions. All bundled into a shock-resistant case for durability. A small red light and whistle is also included on the head-strap as an additional emergency feature. Ultra-long burn time, up to 16hrs use from 3 x AAA batteries.
