Thanks to some early review pics by KimT, I was prompted to visit LifeLites to see if they had more than the blue LED lightsaber blades...and they did!
LifeLites now has LED, minifig scale lightsabers in blue, green, orange, and red. Each are retailing at $8.00 USD. It would also seem that a review of these sabers will be on Eurobricks in the near future.
You can check out the LED sabers at LifeLites.com.
