Are dynamo lights' output measured in a different way to battery powered lights? All the dynamos seem to be around 200 lumens but the Strada RS is for example is 1200 lumens.
If 200 lumens is enough for riding at night, why buy a 1200 lumen light?
Max value. Same reason people by Porsche for commuting to work in. It might be able to do 250mph but you're not going to do it often nor for very long.
