If your criteria are portability and color rendering, I echo what someone said about small HMIs with Chimeras. That is exactly what ENG crews use. The Kobold Dlf200 Reporter light, for example, can be powered by a battery, and is light enough to be attached to the camera via a hotshoe mount, so you don't even need a stand. It will easily fit in a small carry-on bag, including the ballast and battery. Use a XXS or a XS Chimera Video Pro with the light for a nice soft fill if you don't want a hard light (Chimera makes a dedicated speed ring for it). Run & gun to interviews are covered. I happen to have one, perhaps two, for sale, BTW.
I guess I would note a Joker 125 or 200 as an alternative to the Kobold 200.
The Diva (or a Diva knock-off), give you a choice of color temps, but has trade-offs. E.g., it is soft only, it requires a stand, has some bulk and weight, and has some minor color issues when dimmed. A/C only.
LEP looks to be an interesting technology, and promises better color rendering than HMIs. But its early in its development and needs to work out a few issues such as distribution channels, service, and especially price.
You may also want to look at CDM fixtures, such as the 75 or 150 watt versions offered by Cool Lights. They are a/c only and are not hot restrike.
