Dynamo Lights

Yes, I ride this light on one of my fixed audax bike.
The light has seen a load of rain, perfect so far. And the standing light is functional.
It does have a decent amount of power, about the same as my supernova but not exactly the same pattern (beam a bit more like b&m iq). Its enough for road use.

Its not the same quality build as supernova though, very plastiky, yet durable enough. The mount is a bit tricky to get in the good position but you only do it once.
I only chose supernova e3 on my new bike because the rear light is ace' and there is nothing equivalent.

I have the 30 lumen one which was a lot brighter than I expected. This one should be even better.
