I ride in all weathers with cycling to work. 25Km. It also goes through the woods and a piece against the traffic.
With the lamp no problem.
The forest is at level 3 brightly lit so that you can apply full throttle even at night.
To drive against the traffic is simply the latest caustic from the autumn. Most car headlight covers and their own light is not strong enough to illuminate the way to the headlights.
Not with the lamp, just at level 2 and the road is lit here.
In normal street lighting sufficient level. 1
Now comes the but:
The lamp you have to properly align otherwise be dazzled oncoming drivers and this is really bad. It extends the lamp nearing the tires to direct the scattering radius brightens everything ahead enough.
I use the lamp as a working lamp. No more sweating in Baustrahlerlicht.
Top lamp.
But is in no way suitable for children.
