I have several surefire lights of all types and basically all of them have the same color beam (bright white).  I just bought a M600u and of course I had to compare it to the lights I had on hand, namely a E2D ultra and a M300B (purchased this time last year).  

While the new M600u is extremely bright, I am disappointed in the color of the beam.  It is warmer than the lights I compared it to.  By warmer I mean the beam is more yellowish and less white.  

I called Surefire and was told that they are moving to a warmer less white beam as of may-june 2014.  

WTF?  Why would they do this?  I much prefer the bright white beam to the cheap looking yellowish beam of my new M600u.  

Are they just telling me shit to get me off the phone or has anyone else noticed this?  

Thoughts?
