My latest review is now up:
This is the 1x21700 version of the C2 Pro, very similar to the 1x18650 C2 Pro Nichia that I recently reviewed, but with a warm temp XPH70.2 emitter now.
One thing that I have added to this review is a video showing the user interface. Although I am no longer doing video overviews as a matter of course on my @cpfselfbuilt youtube channel, I do plan to post the occasional video when I think it would be helpful - such as explaining a more complex UI, as in this case.
As always, check out the full review on my flashlightreviews.ca website for runtimes, beamshots, summary tables, etc. I hope you find it useful.
