NiteRider Lumina 900 Boost USB Rechargeable MTB Road Commuter LED Bike Light Powerful Lumens Water Resistant Bicycle Headlight, LED Front Light Easy to Install Cycling Safety

Good headlight, battery life average
The good:- Received the 1100 boost in the 900 boost packaging. I’m not sure if this is a labeling issue on the packaging or on the light.- Comes with a mount that works with your bars. You can make it work for a helmet but you are better off purchasing the helmet mount- Plenty of modes with variable light output- Charges quickly- Relatively light weight- Boost mode is great for a race scenario or short rideThe bad:- Battery life on boost mode is 35-45 minutes at best. Running on the lower mode is the only way to get a full ride in. Lower modes still offer enough light for most ridingLight Comparison:- 1100 Boost vs Acrunu 4 Led VS Acrunu 5 led.- The only other light I have is a 350 lumen Serfas that is quite outdated- Subjective feedback: The 1100 boost has an excellent spot. Very bright and very far throw. There is some flood around the spot but it is not significant. I highly recommend this light for a helmet, but as a bar light it might be too much of a spot.- LED color: Very white

Works great MTB helmet-mount. Fast charging
I use this for Minnesota back-country off-road cycling, so I don’t know why Amazon wants me to rate it for “commuting”. This light is sufficient on it’s lowest-level brightness for my forest adventures. I use it for 3 hours at a time, and there is plenty of charge left when I’m done. I mount it on the top of a spare helmet, and it’s excellent. Works great at -25°F, or 95°F, rain, snow, etc. I really like that it can unclip from it’s mount easily, so I can take it inside, or use it hand-held. A great feature is that the mount will “give” if you hit something, so it doesn’t break. Just notch it back straight, and you’re good-to-go! I’m always impressed how fast this light charges. Thinking I need to let it charge over-night, but it’s done before I go to bed.

Unrepentant dishonesty by Amazon
I ordered a replacement for my bike light which was stolen. I received a Lumina 1000 Boost in an opened 900 Boost package. I returned in exchange citing wrong item, and got a different 1000 Boost also in an opened 900 Boost package. Had I been asked about substitution I would’ve been fine with a 1000 in unopened package, but I paid for a new item & have no way of knowing if the 1000 I received had been returned previously. Both packages were opened & contained a 1000 Boost, meaning someone made the decision to send a different potentially defective product and hope I wouldn’t notice. Returned for a refund, I’m not willing to put up with repeated, flagrant & unrepentant dishonesty like that.On the flipside, I called Niterider customer service who was able to get me set up w/a refurbished 900 Boost & a replacement part for a taillight mount. The 900 Lumina Boost is a terrific light, great visibility for me to see road conditions & for drivers to see me. The battery charge lasts a long time, my previous light saw me thru commutes at all hours, downpours, & potholes deep enough to shift my gears and half-open my kickstand. Never had a problem, never came loose, reliable bright light every time. The 900 is currently out of stock on their website but the Niterider rep I was speaking with expected it to be back in stock in a couple weeks.Tldr: incredible product if you can get past the dishonest & reprehensible fulfillment to actually get what you ordered. Buy direct from Niterider instead, give your money to a company who has standards & genuinely cares about your experience

Bright bicycle light.
Most bicycle headlights are only good for being seen, and not for seeing the road in dark conditions. Not the Night Riders, which display a bright forward beam more like an automobile headlight, and which allow you to ride on a road in the dark. There are models brighter than this, but this one, I think, has adequate brightness. There are several brightness settings, plus a flash mode (when you can otherwise see, but need the light to be seen). This charges easily with Micro USB. Be aware, though, if you use it a lot, you’ll have to charge it often.

Just what I was looking for! I had previously owned the lumina 500, and I must be say, it is much brighter (at peak setting). I am very pleased with it.

Tried them on a couple of Mtb rides and I’m happy with them. BUT! note that the advert is misleading, it doesn’t match the product that I received. I bought them from this seller specifically because they were advertising the Niterider 900 Boost, but instead I received the Niterider 900 Micro.
