I haven't been able to find a lot of info about the new LED Littlites other than what is on the Littlite.com website: http://www.littlite.com/products.php?category=10
but they look very interesting albeit a little pricey (like $77 each for the 18" 4-plug right angle XLR model that looks like it would work with the 9000 Pro: model #18XR-4-LED). They new LED models have a mix of red and white bulbs and are supposed to produce a more even light than the standard Littlites, run cooler, and last a lot longer. Also they can be switched to red-only mode for low-light use. I love my Littlites on the 9000 Pro and would be willing to upgrade if the LED models worked and were better. Any opinions?
