Mediacentric comments and is wondering what's your experience with these Circular LED Video Light panels? They are available in 276 LEDs, 380 LEDs, 645 LEDs, & 1144 LEDs. The back of the units appear to have a simple ON/OFF switch and what also looks to be a dimmer knob. [Update] Only one model has dimmer. For others, it's just a fuse. Some images also show a diffuser sock to help soften up some of that direct LED lighting. If you've got the scoop, leave a comment. Otherwise all of these lights can be found below.
I could be mistaken, but to warm these guys up (they are like Cloudy temp) you'd need a bit of CT orange Rosco E-Colour #223 1/8 CT Orange (21x24" Sheet)
