I just used the RN 1500 yesterday on my road bike ride. The light is very bright! I love the USB-C charging and the handlebar mount is the best I have used thus far. It's a beautiful looking light as well very streamlined. I only have 1 thing that I would improve on it. When you're out of the saddle climbing the light can hit you in the face and blind you. If there was a small lip on the top of the light housing that that would prevent the light from hitting you in the face that would be helpful. When sitting on the bike pedaling it is not a problem at all just when standing over the bars climbing. Beside that best light I have used. I'm coming from a Nightrider Lumina 1200.

Just to quantify, I am a commuter cyclist and ride mainly on roads and wide trails. The light is mounted on a cross bike with drop style bars.

I got this light last week and have it side-by-side against a Light & Motion Urban 800. Light pattern is great, fairly narrow beam about the width of two lanes at 40 ft. out. Light color is very white, not blue at all. I run it on low only. The higher settings are almost too bright for oncoming traffic. But on the high settings it's awesome. The center aim is extremely bright. It doesn't waste light to the outside edges and make a perfect commuting light, however, I do notice the tree branches above now. But the best thing is the battery life. My commute is 85-90 minutes one way every day. L&M best battery life on low setting is four rides. I'm going on my eighth ride and the RN1500 still shows full green. May not be a big deal to some, but to me in the winter months, I'm used to having to charge every day riding dark to and from work.

Weight is a little heavier than the L&M. Mounting is the same as Garmin, rotary lock. The only issue I see is that it doesn't allow you to any rotation left or right so it must be mounted straight ahead. This isn't a big deal. There's a little built in, flush visor on the top of the lens that keeps the light low but I have noticed it in my eyes if I climb out of the saddle.

Overall it's a winner. I'll update later as I get more time with it.

I have bought several bike lights for my grandson’s bike only to have them fail one way or the other. I was to the point where He was restricted to daylight rides only then Olight saved the day! I own several Olight products and I knew this bike light would be top quality and it is! I bought the combo RN1500 and the seemee together and I was not disappointed. The lights are super bright and tough. Now my grandson is happy and safe and I have peace of mind knowing his bike is well lit. Thank you again Olight for saving the day or night!

This light is amazing. I’ve bought a 30-40 dollar light then I got a 20 dollar light. Which claim high lumens, the first light was okay. After those, olight came out with this and what a freaking difference. So much so that I’ve gotten complemented by people on how good it works. Then I tell them this is just the low setting. It lights up the signs like a car which stood out right away to me. Haven’t tried It at dark in the Trails yet since I bought it just to ride around at night in my neighborhood. But i will just for fun and see how it does.

Pro:
-I bought this light for the simplicity of an integrated battery and the USB-C charger. For that, 5 stars.

Less Pros, but not all Cons:
-I am not a fan of the GoPro mount and the strap mount for the handlebar but so far, it survived few rides.
-You need tools to re-adjust the light, if needed.

Cons:
-I really don't like the beam pattern as it is was too narrow and only light up straight in front of you, not very functional. A wider flood beam would have been so nice for mountain biking.
-I wish that a full helmet mount was available as I don't own any GoPro.

Overall, it is a decent light but I am simply not impressed. The beam pattern is a big turn off for me compared to my other lights. It does not light up the trail like the reviews are showing.

Functionally the light is great. Great clarity, power, battery life and spread. But, mounting. I’ve got mine mounted under my computer, haven’t tried the bar mount so it may differ from my experience. The go pro style mount works and holds steady vertically but there is very little tension against horizontal movement. Mine gets rotated out of position if I turn my bars far enough to either side and the light comes into contact with a cable. Also the front of the light is specifically designed to be mounted in the original upright configuration. The front cover with the anti glare lines become pointless if you mount it upside down. In addition, the lens cover continues down under the edge of the light body creating a glaringly bright spot if your computer isn’t big enough to cover it (or everyone’s favorite, electrical tape has worked for me so far)
