Moon - Nebula Rechargeable Seatpost Mounted Rear Bike Light 200 Max Lumens, Daytime Mode, 25 Hours Max Runtime

This moon nubila light is super bright! And I mean bright...And good on the battery life depending what setting you have it on.It is quality made and the choice of mounting options are good the brackets are solid with no worries of breaking.I have had a moon brand tail light for years on my mountain bike, (the moon ring tail light) that I purchased from the local cycle shop and I have had no issues with it what so ever, it's never let me down, and is still like new working. (And it's years old) and been threw all weather's heavy rain and snow, and minus temperature weather with no problems at all, very reliable, I just wanted to upgrade to the new versions available.Its as always with moon lights a good one.I don't have it on the brightest flash, it's way too bright, I have it on thesteady /flash as in, its constantly on but blinks at the same time wich is really good and seems to be the best option in my opinion, and will last about 12 hours on this setting option,I have used the under seat clamp bracket option that you also get with it and is very neat, than just attaching it to your seat post.All in all brilliant tail light, you won't regret it on this one. 😁👍

This is the 2nd one I've bought. They're nice and bright, very easy to use. 3 brightness settings, low seems to be enough. I can glance behind me and see it lighting the road and be reassured it's still working. The first one I had I think had rain ingress, but lasted 3 winters of 5 days a week use.

A well made rear light with multiple modes and good battery life. Various mounting options.

This is my second. The first has lasted 6 years before failing. Recharge is about 1.5/2 hours (depending on charger A rating) and that gives about 8 hours on flash. Very bright, very light, a good strong mount and easy to attach / remove. Charges via USB.

One of the best, if not the best back light I've ever had. It's light, bright, lasts a good time and is good looking.

Very bright, fast flashing, easy and quick battery charge, yet small enough to carry in the pocket. The only downside is the light holder, which comes with it. The holder is too complicated to attach to the light and thence to the bike on the seat tube. So I bought a simpler one, that can be attached and removed in five seconds. Nevertheless, the light itself is a great asset on the roads.

Rubbish. Second light from this brand (Moon) and both stopped working within the year. Do not recommend

I’ve just bought a 2nd one if these to replace my first one which lasted at least 6 or 7 years of regular winter use. Bright, lightweight, quick and easy to attach to my different bicycles, and battery lasts several days of a 45min commute each way. A great light!
