I have this light for church lighting. The quantity and quality of the lighting I receive is excellent. I used to combine it with the Yongnuo YN 360II, which also provides good lighting but only outputs 36W instead of 100W. This is a critical difference, so I am buying another one to have as a backup and the Yongnuo will be my spare.
The battery lasts about 40 minutes if I have it at full intensity, so for my conditions, I get the Combo to charge it while it's in use.
Extremely practical, especially for run and gun photographers - videographers.
It takes up little space and performs quite well for a decent video result.
