How the light output from 0-100%? Im really interested in this for filming interviews and such for how small it is and the fact is can run on usb-c and not need an outlet.
The changes in output are not really consistent through out 0-100%. At the beginning it is brighter and towards the 100% the changes are less noticeable. So like 20% of brightness doesn't seem like 20W and so on. Only thing you can be sure is 100% is full brightness and 0% is none. :) For the money, I think it is a good light. But as I mentioned in the video, the kelvins and brightness have to be adjusted by eye and feel. If that would to ok for interviews you have in mind, then sure, it would be a good light. But if you want to be really sure about the color temperature, for example, than this might not be the best solution.
yeah, it looks like that the percentages on the knob refer to how much you can turn the knob instead of the actual output. It also seems brighter on the lower percentages as well.
