Absolute beast of a light. Huge but powerful and lasts forever. Great flash pattern as well for day-use. My first light for super late night and overnight use, only replaced when I needed something with swappable batteries for truly stupid multi-day stuff.

Rated for 23hrs at 150 lumens, 8hrs at 450 lumens, and 4hrs and 800 lumens. The 150 lumens is pretty solid, and 450 lumens was plenty if that ever wasn’t.

Very well waterproofed, attaches to handlebars with attached rubberized strap. It’s very secure when tightly fastened.

Great light, highly recommended.
