    yeah they are but the problem with LEDs is the small viewing angle means you need a lot of diffusion which can drastically cut the light so you need a lot of light. If you put a lot of LEDs in you can possibly cut the diffusion down. The luxeons have a good 110-140 viewing angle but they do get hot!

    EDIT: if you are up to it though try em!

    ok I just did some testing with my current diffusers

    this is with a 2 tube backlight in a U shape, actually it's the backlight picture I posted a few posts back

    1. I tried the panel on top with nothing but the ccfl's behind, and it was kind of bright

    2. then I added 1 sheet of diffuser the brightness increased alot

    3. then I added the 2nd sheet and had to rotate it to change the polarization and holy crap I cant even look at it directly

    4. I added a smoked sheet of plastic to even out the lines from the diffrent polarizers

    i'm trying to take some pics right now, I dont know how they will come out

    yeah it seems to be collecting the light and transmitting it straight out of the panel
