As to Kino Lights, the Divas were not great light quality. The standard Kino Flo's with the separate ballasts and the original style bulbs, those rock. And just about every modern movie you have ever seen uses those. It is Kino's attempt at an ENG style flo that wasn't very good. The "film set" Kinos are great. Better quality of light than even the high end LEDs.
The tubes do have a lot to do with it. The tubes in the Diva's and Barfly's are much smaller and smaller diameter than the larger Kino's, like the bigger Four Foot Four Bank, etc. They explained it to me at Barbizon one day. It's all about the surface area and distance in the tubes.
