The HydroStar SUB flashlight is billed as an ideal emergency tool or a handy device. The dynamo-powered flashlight features single, dual and strobe LED modes along with a "snake eyes" laser pointer. Plus, the SUB is shock resistant and submersible up to 30 feet—so it should be rugged enough to handle the elements.
The hand-crank of the HydroStar SUB will never need batteries, it can hold a charge surprisingly well despite having several modes. About a minute of cranking at a forearm-busting pace will generate about 45 minutes to an hour of usable light from the 1/2 watt center LED, and nearly two hours from the side LEDs and the strobe. The laser pointer, on the other hand, will only get about 5 to 10 minutes.
