I have a blue X1 and I was curious as to whether it was just the optics that gave the beam the blue color or if the LED itself was also blue. I sent Inova an email which stated my question in a clear and concise way and the response I got back was "the X1 has an AR coating on the lens" /ubbthreads/images/graemlins/thinking.gif. Can anyone tell me if the colored X1's all contain white LED's?
