Ah yeah, supernova. Also works price-wise though I can't comment on the light themselves since I haven't used them.
The SON are not bad, just not great value compared to B+M. I haven't found the Edelux lit up the road any better than the Cyo, and it doesn't have any side visibility. (Another thing to note is that if the standlight capacitor is charged the SON will stay on if you turn the switch off, whereas the B+M shuts down completely.)
Isn't he talking about a Supernova light?
And what do you have against Son lights? I am fairly chuffed with my two Son Edelux 2
