I only run NiteRider lights... ordered the dual 1800 and the Solas 250 for use on my gravel bike. As is always the case, NiteRider delivers quality and helps unveil the dark, opening another dimension for life riders.
Cheap? Never. But, you get what you pay for.
I ride a road E-bike with assistance to 28mph. I wanted to get a light that could throw a beam well ahead of my higher speeds. This light is capable of that, however I wish that the beam that it cast, could narrower in nature. I get a lot of complaints from friends that the beam is to wide and high. As a consequence I'm constantly adjusting the beam. On the other hand If I was off road this would be great for seeing the whole trail.
My other issue is that the mounting hardware that it came with was not good. I couldn't find a place on my bars that it could project a straight and level beam. It cost me a lot to get the after market mounts that the makers of NiteRider had recommend. Recently I discovered that Lezyne has upgraded mounts that can work for NiteRider at a fair price.
The light is very powerful. It comes with 4 levels of intensity. I generally use the two lowest setting unless I'm going down a steep hill. Overall it lets me ride on the darkest of road at any speed that I can muster. Just wish it offered a narrow beam setting.
Great helmet mounted light for night trail riding, especially when paired with Niterider 3600 bar mounted lamp. I think I have better lighting than most cars have. However, the Lumina 1800 is just a tad heavier than most but it's a long lasting light.
I leave my house at 515 and i need strong reliable light to take me through dark, unlit roads. This NiteRider is so powerful i haven't even had to put it on the burst setting yet and i feel much more secure.
This light is plenty bright but I have a 1500 lumen light that seems brighter, the lense seems to dull the beam and is quite opaque compared to other lights I've owned. For the size and weight I'm pretty happy with it though, on the middle setting there is more than enough light for most occasions.
