I wanted to try RGB on the camera and the initial price seemed good to me. A couple of things to note right off the bat is the 2000mAh (which was left with several hours of low battery). The color reproduction for the entire spectrum works very well. There are 3 general modes: normal dual tone (from 2500K to 9000K, but I did NOT test CRI), full RGB mode and color effect mode. I also love the fact that there are 20 different color effects like strobe, police car, party flash. Functionally, it's fairly intuitive, with a button for power and modes, and two dials for choosing each setting (color temperature, RGB color, and effect) and intensity. This item is USB-C powered and I tested charging and using it at the same time and it actually works. So if you want to power it from the AC adapter, it should work fine.
