Ravemen not Raveman. I kept making that mistake, too.I am quite surprised that raveman managed a somewhat decent cut-off with fresnel lens design.
The CR1000 fresnel lens seems to have a more complex design. and I suspect a better shaping lens to back it up. The CR900 has a circular different fresnel only over the die of the LED with similar vertical ribs eleswhere and I am unsure how much the beam shaping lens differs from the R1000. I have a shaping lens plus fresnel on a DIY generator light on the errand bike I made 8 or 9 years ago. I did get a lot less light above the midpoint and more near it. The CR1000 seems to have realized then potential of the two lens system.
I can swap out the CR1000 and CR 900 on the helmet and use my Cell phone to compare those cutoffs shining at the door. I can also lean the bike on the door at one end or even on the house with the lights at the door jamb and let the beams fan across the door for another take of one CR900 or the CR1000. For fun, I think a temporary hood on the CR900 to cut off more of the light above the hotspot would be interesting to try. I suggested this when I got them but am not riding enough at night to have tried this yet.I'd love to see a garage door beamshot of the CR1000 vs the Outbound Focal Road or a beam shot in with some bushes along the side of the trail/road to get a better estimate of the cut-off quality!
I did comparos when the Planet Bike Turbo Flash came out. Cost me about $100 and I had use for the best from the test. I am not so flush with cash that I can afford a $200 light I don't need. Still, I understand the desire and have filled that in the past.
Technically a larger light body like the Trek light (which I reviewed here
maybe 5 years ago? The only time I was sent a light for that purpose.) and the Outbound Focal Road allow bigger lenses/reflectors and the LED shoot down design so it is inherently better at a great cutoff. The Focal Road it is also almost 3 X the price. So 2 CR1000's would be a better comparison (would give a nice redundancy and allow lower power/longer run times).
Another factor kicks in. The camera can lie or mislead as it is not the human eye. I have an old Stealth POV camera that had the highest night vision capabilities at that time. I don't know of any safe gravel roads or trails within 25 miles for night riding but I will do what I can.
