Now I wanted to have the camera light, I can also use batteries. The search began. I was amazed at what cost these things. Halfway reasonable lights start at 300 EUR. I did not pay and was looking on. Then I came across Yongnuo YN-300 and had great skepticism as to whether the thing at all good enough now. OK - try. Ordered -> Supplied -> unpacked and immediately at the next rotation used. Well ... The thing is for the money (for me) more than perfect. I ordered at once a second and even found at E-Bay a similar light with 600 LED's for 125 EUR (Yongnuo YN-600). This I call now my own.
I am very happy because the lights do what you need when filming. And indeed they do ... LIGHT.
The light intensity can be continuously regulated from 10-100%. The color temperature can also switch easily.
Included were 4 light filters. It's nice, but I just use the white.
There is a remote control. This only works when you hold the light from behind straight. Since the lights are often left and right, and I know where are, you can not get around it and needs to light walk to make appropriate adjustments.
All three lights I run with Patona battery NP-F970 (also bought from Amazon).
