I tried directly the LED light. Looks good, but is too weak. Is bright, but result when a Cam and from switches to the finished film not a big quality improvement. In short, you can save the USB object ring. Dear proper Buy photo lamp, which is not much more expensive. Must look times whether it Photo Lights is on battery, otherwise I use is the nothing. What is even more stupid, where can I get if I want to film on the go, a USB Connection ago who gives me the power to the USB ring ???? Here helps only a separate Power Pak.
Faszit: Am really disappointed. Have more promised. Luckily the USBN ring was cheap, what the quality is saying.
