I've been diving this light on my DSLR and really like it much better than the Fantasea LED44 I was using before. Brighter, carries farther and has a softer light. Great build quality, all aluminum body, battery compartment clips out for easy loading. Magnetic switch, etc. Really bullet-proof. I thought that the long shape of it might be too long, but in use it provides an easy handle to position the light.

It would also be a good combination focus/video light for point and shoots on a dual handle system.
