Likely due to AWB on the camcorder, I have a sample for review and based on the limited time I've been using it, the beam definitely doesn't shift (although it's slightly green around the hotspot but on par with most of the XM-L lights I've recently reviewed). Also, I'm happy to report that after a brief initial dip, the light runs pretty much regulated for just over 2hrs on AW 2600's. This bests their ANSI claims since this was for full output at that duration. More to come and hope to have review up by next weekend.
Cheers,
Tim
