Kino Diva - good to go. Flolight or other knockoff - white balance to the light, or shoot a raw still of a gray card and open it in Photoshop - check the gray value for even RGB #s - like 125R 125G 125B or within a few points. Many of the kino knockoffs have so-so bulbs. My Flolight brands need CTB and minus green - they're yellow. You can play with raw stills to suss out what gels may be needed by sliding the color temp and tint sliders until your grays are even.
I shot a lot of work with the 550D, but knockoff flos can give you some serious headaches.
