More light for macros

I bought this ring light, because I like to be evaluated before the lighting conditions before the image is created. But you have to also go really get close to the object, so that the light is strong enough to illuminate the object actually complete. The ring can both operate fully and only one side. There is a top Schalter.Es not suitable each lens. If you have one that can zoom in, then you can always see at the beginning of the edge of the ring light. But otherwise nothing is observed. The build quality is ok, although looks a bit cheap, but holds. There are also many top rings for different lenses here.
