Good order. Sufficiently powerful and uniform illumination for my amateur use. However, indirect light (eg white ceiling ....), a second torch would be well received venue.J'ai 1:20 autonomy with R6 1800 mAh. I mounted my Sony batteries without problems (directly) and Panasonic (with the supplied adapter). Warning: the photos suggest that the attachment is compatible with accessories "GoPro". It is not so because the legs are notched and thinner. This would require tightening to death at the risk of crushing or notching breaking legs. Do not count! The barn doors seemed to me utterly useless! On a single light source, I understand. But, no. I explain: for a single light source, the edge of a component induces a light diffraction resulting in a more luminous band followed by another less bright. Thus orienting (for uniform illumination) of the flap so that this distortion of the light is not visible on the image. But in this case, it was .... 10 .... 16 rows of light sources! Which induces diffraction by component 10 in the horizontal and in vertical direction 16, in the manner of a light passing through a Venetian blind! To banish so. Unless you look for a graphic effect. I removed these components and thus eased the torch 50 gr! The on / off button is of type push-in / push out. I do not find it very convenient and would have preferred a rocker. Well done to the battery capacity test. This torch quickly became indispensable to me. Glop, glop, glop ....
