OK I looked at a couple of pages about the Ravemen CR900. It looks excellent, and the price of $77 isn't bad at all. But the beam doesn't look SVTZO compliant. I know I'm being picky, but I love my B&M lights. I have a bad reflex of looking into a beam's hot spot. This beam's hot spot isn't as bad as round beams, but it's not as good as a B&M beam. The B&M beam is a trapezoid, and I can aim it so there is no wasted light anywhere. That's why 200 lumens (my estimate) suffices for me. It's not enough for some people, but it's more useful than some higher power lights because of the shape of the beam.
