I can say so far the following:
The brightest in the core area of its oval light beam is clear of Supernova. Revved illuminated the farthest (then displayed but also the oncoming traffic)
The headlights with the lightest, most uniform and widest broadcasting is the Philips
The other models are all but also very good headlights illuminate neither as bright as the supernovae or so wide and evenly as the Philips.
All processing of the case is the supernova of course better than all its competitors cost.
What bothers me a bit is the lack of reflectors.
The other Schin launcher always bring a with that is indeed demanded by law.
So you have to still tinkering aside a white reflector to be compatible to STVZO. :-(
But that should not stop anyone from the high light output of this part to bring to the wheel.
