This is a ten light ring of light that really dims. Not 69 light glowing less to give a touch of dimming. I had fun with this flash, nothing professional, just experimenting. People have complained that the ring of light spins too easily, and that's true. My solution is a 5 second glue that cures in UV light. 4 small drops, more or less evenly distributed on the base, ensure the right friction. With all adapter rings it fits my Nikon and Panasonic cameras.
