Dave,
I would ask for a demo so you can check them out. They are much bigger than any kino fixture and throw alot more light. The closest comparison would be the blanket light, but the lumapanel is much easier to operate, plug-in, store, etc. They sell it as a piece of a large source as opposed as nessesarily a single fixture. Some of the pictures of the rigs are massive, but alot more controllable than spacelights or coops.
They are very user friendly, i got 2 for a demo on a small shoot. I'll upload some pictures.
