Negatives:
- The dial is quite shaky
- The maximum brightness is only very selectively and then drops sharply.
- Brightness settings less than the maximum result in a flicker in video recordings.
- The batteries do not last long. After half an hour, the brightness drops visible.
- For maximum performance with 15 ° C ambient temperature, the bulb has so strongly heated after about 30 minutes that a battery has exploded..
Conclusion:
At first I was quite taken with these lamps. - Possession of 3 pieces for filming. - In retrospect, the money was thrown out the window and I think the product even dangerous.
