Made with a 90° angle, the HC33 is a flashlight you can wear on your head, over a helmet or directly on your head. The nylon headband is comfortable enough you can wear it without a barrier, and stable enough to stay attached while you're looking around in the dark. The HC33 is controlled by a single button on top of the head, clicking when you're turning it on/off or changing modes. The light up to 1800 lumens is powered by one 18650 or two CR123s (batteries sold separately).

The HC33 is machined from aerospace-grade aluminum alloy, given a military-grade hard-anodization and knurled on the body. The diamonds cut into the body make holding it in your bare hand easy on the skin.
