This produces a very wide angle beam, and a completely uniform light with no hotspots or variations in the light, so it makes for the perfect video or photograph light.
We use these for photography rather than strobes as they're much cheaper, easier to use, and more versatile as you can use them for video as well. If you're a full on u/w photographer with a camera that needs it's own bag then you'll probably still want your strobes, but for the average person that wants to get some great underwater photos without the expense, hassle and space these work brilliantly. They work brilliantly with a GoPro or any compact digital camera.
This has white and red LEDs. Red work great for getting up close to the marine life as they can't see red light so they won't be spooked like they are with white light.
