DLPLIGHTCRAFTER: Are Any Components Different in Rev. E vs. Earlier Versions?

Part Number: DLPLIGHTCRAFTER

Hello,

My Lightcrafter was rev. C or rev. D when purchased. Is the rev. E any different from the one I purchased, specifically the light engine? I am looking for the specs of the LEDs used, and I'd like to make sure that I am looking at the right LEDs. 

Thanks,

Quinn
