NiteRider Lumina Micro 850 Front Bike Light LED USB Rechargeable Water Resistant Mountain Road Commuting City Urban Cycling Safety Flashlight, Black, 6783

I previously used the $10 bestseller BV light, which uses AAA batteries. With that cheap light, you will eventually be burning through your batteries, and it's just not bright enough for use at night or even twilight. Moving to this light was a huge upgrade as it allows for actual night riding. The light is very bright on the medium and high settings. The lumen output is honest and appears to be accurate (I received the 900-lumen model.) It's scandalous that Amazon allows bike lights with ridiculous 9000+ lumen claims, but this is the real deal. The mount is secure with my 23mm handlebars, but it's still possible to tilt the light down by hand to avoid dazzling people at night, or pointing straight ahead for use in the daytime to be visible to cars. I primarily use the light for its flashing function during the day, and its battery life is certainly long enough to not be annoying. I appreciate the red light showing when the battery is low. The construction is good and I've had no issues riding in the rain. My only criticism is that the way you need to hold the button for 3 seconds to turn it off or 5 seconds to enter blinking mode (or walk mode) is not convenient or intuitive. I think that it would be better if the light simply cycled from Off>Walk>Low>Medium>High>Blinking>Off and optionally hold 3 seconds to turn off. For the price it was very good value, but the price does seem to fluctuate.

I selected this light for its defuser lens, which spreads the beam sideways. That's particularly helpful for me when I get caught out on a winding trails at dusk or night. If I were to do planned night rides I would probably add a second light atop my helmet, without a defuser. NiteRider model selections include with and without a defuser. The compact Micro versions such as this one are well suited for helmet mounting. The light is sufficiently bright to be effective at the middle brightness setting. The battery life has been more than sufficient for my needs, but I haven't done any multi-hour night rides and I haven't used it enough to get a good calibration of the full battery capacity. The clamp style mount that comes with this model seemed to work, but only barely for my small diameter handlebar. It looks vulnerable to tipping under the jarring of a rough trail ride and its rigidity doesn't work well for clamping to a tapered section of a handlebar. Also, it's a bit bulky. I prefer NiteRider's rubber strap mount, which I purchased separately. It is very solid on my bar, with no tendency to tip. One of the reasons I chose NiteRider was the availability on Amazon of alternate mounts that can be purchased separately. That's reassuring to me. I recently retired a perfectly good Kryptonite light because I lost the mount and could not replace it.

Great product, somewhat light on the wearer. Easy to use. Charging area is small; uses an usb charger. Watch out on the rubber piece covering the charging area on the product, that it could easily tear off. Make sure you close it, don’t leave it hanging off. This rubber piece protects it from moisture and dust. The charge lasts according to specks. The light output is immense. Do make sure when you get this that you read the directions, due to the product has to be charged at least 2 to 3 hours before using and it has an anti-turn on mode(press power on button when fully charged for at least 7 seconds to turn on.) be patient. This product does work! I use it on both handle bars and helmet(still waiting for availability for the helmet strap). It is highly recommended to use both on ones helmet and one on your handlebar for night riding. Awesome brand and product. Customer service is a plus. I did call them due to a strap broke on my rear light. They sent one out for free within 2 days. I would definitely get another one.

I've only been mountain biking for about 4 years now. This is the 2nd light that I've purchased and am very happy with it. My previous light was a Niterider Swift 450 and I felt it was adequate for the price. I dropped it in the street and it was run over by a car hence the need for a new light. This 850 is a very nice, bright light. My only issue is that I preferred the simple strap mount of the Swift model to the way this one mounts. Quick mention, I read some reviews that gave the light 1 star because it would not light up. I almost fell into the same trap until I read to instructions, you need to hold the button down for 7 seconds in order to unlock it.

Niterider nailed with this one. Excellent light at a more than fair price. Solid mount and fits well on both the bike handlebar and with helmet mount.

This is the perfect bike light. It’s very well constructed using sturdy components, is highly water resistant, it’s small and light but has a very powerful beam, it has a well designed handlebar stand that click-swivels to set the right angle, it has a glass lens, a thick rubber tab covers the USB port that seals very tightly to prevent water damage, it has a long battery life (9 hours in low-mode), and a very attractive design. It is a perfectly designed bike light. Buy it, you’ll love it. IMPORTANT NOTE: after removing from box, hold down the on/off switch for 7 seconds to disengage the power-lock mode. Many bad reviews were from people who didn’t unlock it—if all else fails, read the instructions...

Good light, especially considering the price. I use it both as a daytime light (in the flashing mode) and a main light during night (in the constant mode). The lower constant mode are sufficient for night riding. The beam pattern is great, doesn't seem to blind the opposite traffic as much as the other high-power lights I own do. Apparently, not all micro-USB cables work for charging this light. Of the 7 cables I happened to own, the one that came with the light and two other newer ones worked. I guess there are different standards within micro-USB, I did not care to look up. Just wanted to let the potential buyers know of the fact - not a defect or a flaw of the product at all, of course.

I have two of these headlamps that I bought in 2019 and 2020. Since then I have ridden 11,800 outdoor miles which took 882 hours based on my strava data. I use a headlamp on every ride, mostly in the daytime flashing mode and occasionally as a solid headlamp at night. I'm impressed that the batteries on these things are still going and can still see me through a 5+ hour ride on flashing mode. I actually lost one of them for like 6 months and when I found it in my garage I thought maybe the battery would be toast. But I just recharged it and it's been going strong for quite a while since then. That's impressive. All that usage has eventually taken a toll, though. A few times the lights have fallen off the mount on rough roads and went bouncing off the pavement. That might have been user error - maybe I didn't have it securely snapped into place. But on one of my headlamps the rear portion of the mount that allows it to securely snap into place has broken off on one side (see photos). Both sides broke off on the other light and it started falling off pretty easily. My solution has been to put some shoe goo on the mount to add some friction and that has been working well so far although I've only ridden about 90 miles since then.

Gostei muito da lanterna, super potente Recomendo

I lost my last bike light and found the exact same one for name half the price . It's really good for not t riding. Highest beam is good for off road and low to mid is great for on the road. Flashing does the job in daylight in the road. Really good value.

Eccellente luce per bicicletta o monopattino. Molto compatta e luce molto molto intensa. I lumen dichiarati sono veritieri.

J’ignore ce que donne les différentes puissances de Lumens d’autres appareils, mais celui-ci m’a complètement bluffé. Éclairage DVF de chez NiteRider (visible même en plein jour ! Si si !). Et la nuit, on voit largement où on met les roues. J’adore, c’est exactement ce que je voulais pour mes sorties ! Très content.

Una belleza, sin problema en que se haga de noche, un amigo compro otra, con 1200lm por el mismo precio... Pero no le llega a los talones a esta, su luz es más amarilla, la de la Nite Rider 850 es blanca y brillante, es una maravilla, en su máxima potencia ilumina Como un coche o más, no he tenido tiempo de probar cuánto dura la batería, máximo he estado 1 hora usándola, ( por la montaña) y va genial. No quiero saber cómo son las de gama superior.
