SONdelux Disc Centerlock Hub Dynamo - silver polished.
SONdelux is the first hub dynamo generator specially with modern LED headlamps (as Edelux and B & M Cyo)
In conjunction with Edelux has the SONdelux Hub Dynamo since 2009 the roadworthiness approval for all wheel sizes (16 " -28 ")
An LED is - unlike the halogen bulb - even at partial loads highly effective, ie when operated below their rated power
Therefore, it is no longer necessary to Dynamo so to build that it reaches its full performance at the lowest possible speed
The SONdelux is therefore smaller and lighter than a hub dynamo for halogen lighting (SON 28)
The idle power is reduced compared with the SON 28N 28 to 30 - 35%
In its robustness and quality in the execution but corresponds to the SONdelux the SON 28
