Put it bluntly: Dolle lamp!

I use the head light of Yongnuo professional reportage area, sometimes for minor short film projects and am very fond of this part. I have also other lights (all LED lights) used in this size and this is in my opinion the difference in detail. Light they give all, all 160 LED bulbs also provide approximately the same brightness and luminous efficiency, the weight (caution with smaller cameras that are very fast wobbly!) Is the same in about. What I particularly like about this model is that the switching on and off does not work like other via a rotary knob that simultaneously adjusts the brightness but that the Yongnuo has separated these functions. So you have to turn on a real (pressure) switch and the brightness vote be "abused" two pressure switches. So accidental operation is almost impossible and when it needs to go fast times, the pressure switch has a real speed advantage. The base fitting is much more stable and reliable dissolved as with most other lights that have almost exclusively via a wobbly lamp base with two completely unstable joints.
Thumbs up for this device!
