I took my sea kayak and my SureFire E2D LED Defender® out on the Florida Gulf late one night. The moon barely lit the way, but it provided just enough light to notice movement about fifteen feet from my small kayak. I immediately took out my E2DL and blasted the 120 lumens towards movement, but I saw nothing. The same thing happened two more times, but I still couldn't see what was causing the water to stir.
The splashing grew more intense and closer to the side of my kayak, so I submerged the E2DL in the salt water, clicked the tailcap, and saw the silhouette of a big crocodile. As soon as the blinding light lit up a 20-foot radius around the kayak, the croc quickly turned and swam away. Thanks to the power of the E2DL's blast, I thankfully didn't have to use its strike bezel that night.
