Speaking of LED lights- Lightpanels just announced a very interesting new 1x1 panel that lets you adjust Color Temperature
as well as Brightness.
This is a very nice feature, considering that the LED panels are cool to the touch (not like hot lamps) & require very little power. Its a little too expensive right now (About $2500), but this is a good sign of things to come as prices will definitely come down with time. I think their non-temp control 1x1 models run just over $1,500 and I saw one at Vincent Laforet's workshop. It was extremely nice. Everyone I know that has used one has very positive things to say about them, the one major drawback: they have limited range.
If you haven't already you might want to take a look at their website, they have a lot of great information about video lighting:
I found their "On the Set" Section
to be quite surprising, there are a lot of big time productions that are using these more and more.
