Moon Nebula Rear Light - Black , 100 Lumens

Really. I bought this guessing that it would be better then my old LED black lights that I got with my bike from halfords some years ago. It really is in a different world. If you crank it all the way up its literally too bright to look at. So its possible to use the light in the daytime to be visible as well. Its a shame that back lights usually come with smaller rechargeable batteries, this is no different and you get around 10 hrs on the strobe mode. Its a great light with good vision at the sides too. Highly recommended

Wow. This light is GREAT!!!!Pros:- VERY bright on anything above its minimum setting.- Good battery life (unless on "overdrive" max brightness).- Superb waterproof design, including its button and the micro-USB socket cover.- Incredibly solid build quality. Gorgeous machined metal body and thick acrylic lens.- Comprehensive fittings, including the most sturdy seat-rail bracket ever!- Outstanding wide-angle visibility. The thick lens is curved at its edges to transmit light to the sides.Cons:- Low battery indicator (tiny blue LED) is very hard to spot amongst the really bright red LEDs.Overall, an amazing quality light. The sort of light Apple would make!

Literally brilliant. Think I may have reviewed these already. Now have two sets, even on the lowest settings they are incredibly bright, can't help being noticed by drivers and that's the point. Highly recommended. No issues with these so far. Just keep usb charging.Update as of March 2019 - these lights are used every day all year, they are charged about once a week, usage 6 miles a day. Still working perfectly and haven't even faded, have never let me down. Thanks

as a car driver myself, I know how difficult it is to spot cyclists at night - many of them have puny little rear lights that do not adequately signal the presence of a cyclist. The moon nebula overcomes these two issues: 1) it is one of the largest rear lights I've come across without looking clunky - I have mine attached horizontally under the saddle with an adapter that comes along with the light. 2) it is BRIGHT! I commute 12 miles, for long stretches on dark country lanes, and finally feel safe. Highly recommended, even if the price is not cheap.

Best bike light ever!This light is super bright. Lights up the road very well so other road users can clearly see you.It has 4 always on modes, 2 flashing modes and 1 strobe mode.Quick to recharge.Worth every penny.

I did not extensively use it, only during winter times. it stopped working. when it is connected to the charger, it works otherwise doesn't. I don't know if it is the battery life or not.

This is such a good piece of kit. Brightest I've come across and I use it every day on my commute to and from work. Well made and feels reassuringly solid. Easy to mount and very secure. A number of different settings to choose from. I use the brightest to commute and the least bright when out for 4 hour rides on my road bike at weekends. Has never let me down. Charges through a usb cable that comes with the light. Recommended.

I bought this from Y mount frames company as I completely trust their service. The light was cheaper with them also. The light has arrived a day early and I have had time to have a play. What can I say the light is very bright. 100 lumins is very bright. I love this light.
