Fish are attracted to light, so you would have a lot of them under your board. Plus, many waterways have restrictions on usage after sunset, due to the increased danger of drowning.

The light should attract some fish Rick

That kind of light around you will diminish your view of the stars. I have swam in a lake at night; bringing a light would have ruined the experience but not as badly as if the cop with a spotlight would have shown up 3 minutes earlier.

Paddle Floridian waters during blue crab season would be interesting...especially accidentally falling into the water. I do wonder how large nocturnal marine predators respond to a lighted slow moving silhouette though.

...aaahhh, boats at night require navigation lights (red, green, white), not so you can SEE, but so YOU can be SEEN. Likely illegal in navigable waters - at least in Canada

Wonder what impact blasting light during the night has on marine ecosystems.... With sound, water AND light pollution we're really serving up the goods to our marine cousins.

The light will attract fish, and here in Australia big ones with big teeth, SHARKS. But we wish you the best of luck, just wear your steel pants.

Ukatama is right: best to use this in lakes where the night predators are not interested in an easy meal larger than a 5lb fish.

looks like the makings of a cult horror picture to me, paddle out in dark to take pictures with light then turn on lights only to find out a giant school of hammerhead sharks under you, where did i put that cyanide pill?

Night is when the sharks come in close to shore to feed...
