More LEDs
ChrisA,
Sorry, I didn't post links. I am playing hooky from editing as it is & was lazy. I have noticed that GE is now selling Reveal LEDs in the traditional form factor. Saw them at Target. So those would be great for practicals and might be cheaper yet than kino bulbs; I don't remember the exact price. However, the output of these bulbs is much less than the big CFLs which can rival halogens but probably have better spectrum qualities. Tungsten Reveals always looked great.
Nice thing also about the LED strips is you can make small nook lights for accents or car interiors. Mathews & Manfrotto make plenty of foamcore attachments which would be handy for attaching your LED boards to traditional stands. The Avenger F1504, 143F or 143FD forks might be of use.

Great thing too is LED strips are linkable so you could size your units up and down. I was sketching out some designs for LED boards as well. If you velcro the backs of your LED strips, and then lay out different sized foamcores with corresponding velcro strips, you could have 2 banks, 4 banks, 8 banks ready to go. Just lay down as many 2 ft. strips as you need and plug them in to each other.
DIY IDEA:
Picture a 2 ft. 5/8ths rod, w/ a pair of manfrotto female adapters (014ms etc.) or card-a-links attached. You can just plug in the foamcore forks via the 5/8 pin to the open card-a-link receptor or female adapters, tighten and go. Add a 2 ft. foamcore to one side for a 2 bank, add another to the other side for a 4 bank. Or add 2 four bank foamcores, etc. to go big. And then one more card-a-link or female spigot to attach to a light stand or C Stand.
If you need more stability so the foamcores don't sail in the breeze, you could use a 5/8ths cross for your rods. Maybe 3/8ths rods would work too for even lighter or smaller set ups.

You could also do 1 side of the foamcore white, and glue some mylar or Lee reflector material to the other side for a little more kick.
I'm guessing $100 more or less for the above set up, LEDs, not included.
FILM LEDs:
I was going to start on something like this when I saw the Cinemills Razor LED units at Createsphere. They told me they were about $40 for a 12 inch housed LED strip unit which are chainable. You could build your kit up as you go with these guys a unit at a time perhaps. And they also make kino style housing for the strips. More expensive perhaps but over the life of the investment maybe worth it, particularly if you can add as you go.

CONSUMER/INDUSTRIAL LEDs
Here is a LED "Flo style" unit for $70. Similar to the Razor LEDs:

Wholesalers sell those Rosco style LED panels much cheaper but you have to buy in bulk I think.

Much cheaper than film LEDs but weight???
