Review ravemen cr900 900-lumen ultra-compact headlight – bikerumor

If you’re an avid rider, or commute to and from work, you probably spend a good bit of time riding in the dark. Which means you’ve probably also spent time researching what lights to buy. There are a ton of options out there, many with very similar looking specs. Where Ravemen’s light designs get interesting is in the following sentence: “To our regret, most of the high-output bike lights on the market have no anti-glare capability, which is dangerous to oncoming traffic.”

Unboxed, the Ravemen CR900 is indeed a very small package. Measuring 98mm x 30mm x 33mm and with a claimed weight of 115 grams including battery, it feels light, yet solid in construction. In fact, the CR900 has served well as a ultra-bright, portable flashlight for those times one needs to go pottering in the back yard, late at night (which is totally normal around my place).

For this, a spotlight setting would be helpful, but that’s getting off topic…

115 grams of weight is all well and good for just the light body, but with the bicycle handlebar mount, the true value of the light’s functionality and total system weight are better recognized. Pictured above with the supplied bike mount and an O-Ring, which isn’t needed at all for mounting the light (more on these later), deduct about 1.5 grams for that, and you’re looking at approximately 132 grams for the Ravemen CR900.

Above is the CR900’s unique split lens, behind which resides a Cree XM-L2 LED. Once upon a time when it was financially viable, I made my own bicycle lights. The housings of my home-made light builds mostly resembled a roughly hewn, broken off piece of the International Space Station, but Cree LEDs were the ones to buy. I haven’t dissected the CR900, but typically behind the lens in a tube shape light design resides the LED, with a reflector strategically placed to surround the LED at its base and project that light forward. The lens in front of the reflect does the rest of the work.

The Ravemen CR900 handlebar mount is a doddle to use, and the front strap works just like a waist belt. Pull the strap through a plastic buckle to the appropriate hole to tighten, and you’re done. The light slides in from the front of the bike and clicks into place onto the mounting rails, and is released by a small tab at the rear of the mount.

The uber-compact CR900 doesn’t take up a lot of room on the handlebar. The main light body is constructed from anodized aluminium, and the touch pad and other parts, a durable plastic of some kind. All components have stood up well to a few weeks of regular use, including some heavy Florida rainstorms. The light is IPX6 water resistant, meaning the light is capable of being exposed to the elements with no risk of failing. Additionally, it is rated to impact resistance of one metre.

Here’s how Ravemen describes it: “Through professional optical software modeling and simulation and using a highly efficient lens, we successfully created a light similar to automotive low beam headlight, providing broad (close) range flood light with anti-glare cut-off line, no dazzle and glare for oncoming riders and pedestrians.” To which we would add “cars”.

I had a distinct lack of willing volunteers to test the anti-glare feature, but did chance upon two runners on a local shared pathway at night. As we rode and ran towards each other, I noticed the runners didn’t characteristically shield their face with their hands as they came into the beam pattern of the CR900. Speaking of range, Raveman claim a maximum of 105 metres / 340 feet. Beam Shots and Run Time

Above, the CR900 on High. I don’t have any way of determining if the those lumen counts are accurate, but the cool white of the Cree XM-L2’s flood beam provide excellent coverage of the pavement or gravel road. There is no spot whatsoever in this beam pattern, which could be perceived as a negative by some. ( Tyler’s note: In my experience, the lack of a spot or concentrated center beam creates more of a distraction and unintended “tunnel vision” effect, so this broad, even pattern is a good thing.)

The Ravemen CR900 is almost the perfect bicycle light. The remaining battery run-time feature is superb and the light body is compact and lightweight. Personally, I love the beam pattern emitted by this light and it would be my go to light for road and gravel cycling (sans heavy duty descending), but only if I could extend the run-time with an external battery.

Priced at $75.00 USD depending on where you look, the Raveman CR900 is a well-priced bicycle light, especially you consider the remote switch, easy-to-use touch pad, seemingly high quality construction and good looks (even if lights aren’t that pretty). An optional GoPro type mount to sling the CR900 below one’s handlebars is available, as is a helmet mount.
