The 700-lumens of our Waterproof LED Spotlight&';s CreeA(R) XM-L2 7-watt LED illuminate everything around you, making trails easy to follow for as long as 1.5 hours at full power, 4 hours on low (350 lumens), or up to 4.5 hours when operated in SOS mode. A rugged combination of ABS plastic, rubber and TPR construction ensures nothing slows you down-including run-ins with more moisture than you&';d anticipated. Not only is it entirely waterproof, but it also floats and is submersible to 1 meter. This light also features a rescue whistle, and magnetic trigger switch with an integrated locking function for every setting (high, low, SOS, red strobe and off). Rubber-painted housing surface for a sure, solid hold.
