What we have here is Ravemen's first 21700 (4000mAh) single cell light with its newest low glare optic treatment. Both these features ended up being a factor in the CR1000's main advantage over its competition, its exceptional runtimes. So lets look at the specifications, pro's and con's, and what it's been like using this light (almost every day) for the last couple of months.

CR1000 Pro's & Cons
Short charge times
Small (physically) and reasonably light
Great beam pattern
Flash modes in main program
Small rear mounted mode button can be hard to find and operate with a gloved hand
Strap mount not 100% stable when MTB riding
Initial output is not spectacular (better than claimed though) and trails my other 1000 lumen lights (Cygolite 950, Ceco 1000) but that doesn't paint a very accurate picture of perceived light power (read the beam pattern section for an explaination of how the CR1000 more efficiently uses its lumens). The other lights output degrades much faster than the CR1000 too + they have considerably shorter runtimes for each mode.
I tested the top 3 modes and my results were within 5 min. of the Ravmen claims.
The new style optic works GREAT! For its output it actually increases the perceived amount of light plus places the light in a manner that allows more efficient aiming reducing glare for oncoming traffic and not wasting much of its output on unimportant areas. One of the first things I noticed using the CR1000 was how comfortable I was and how effective the 350 lumen (375 measured) mode level was which is well under my usual 500 - 700 lumen comfort zone. I did a lot of side by side comparisons but in every case it took more measured lumens for the other lights to give comparable visibility.
Thinking about it and looking at how the brightest part of the CR1000's beam was at the very top I realized it was using the majority of its available light between it max throw distance and the front of the bike where a typical light aiming for distance actually wastes close to 50% of its available light aimed up in the air since the center of the beam is its brightest point. Aiming most lights down for lower top spill puts the brightest part in the wrong place and the flood of light in the foreground usually limits distance vision.
Sorry about the wierd angle of the photo.
Anyway along with the beam being very efficient overall it also places a good deal of soft light around the front tire so turn in vidibility is also very good + overall the beam has very smooth coverage.

UI & Mounts
This is the area the CR1000 struggles in. I don't care much for strap mounts and even though this one is not too bad it still allows the beam to bounce around a little when riding off road. Luckily a solid mount is available. The next issue I have is the rear mounted mode button. Its a bit hard to find and/or operate for me with any sort of gloves (except fingerless) especially with the remote or usb cable attached. The remote helps a lot and I'd like this light quite a bit less without it. Which leaves the UI program that includes 4 forward beams levels + 2 flashing all on the main program. Lets just say I found it awkward having to press the remote button 5 times to get from med. high to the brightest mode. If the CR1000 had a double click to high function that is common to these type of lights it would be a huge benefit.
In spite of the UI issues I consider this light a winner! If you can't live with these issues at least you know in advance. For me the positives far out weigh the negatives. It's light, bright, super beam pattern allows it to function well for mtn and road + as a helmet light too, has super long runtimes especially considering you can usually get by running it a mode lower than most lights, and fits my need perfectly so would still give it a solid 4 out of 5 stars! Thanks Ravemen for giving me the opportunity to review this light and share my thoughts about it.
