Hey all,
I've got a new Seca 900 head unit that I'd like to unload. It doesn't have a battery or charger, but if you've got a previous generation Light & Motion system (e.g. Arc or Arc Li-Ion), the Seca 900 is backwards compatible with those batteries. The mounting bracket is integrated with the ligth itself and I've got a helmet mount that you can have as well (although this thing is so bright you'll probably not want to mount it your helmet. The bar is more than adequate).
I've been doing the Luge on Thursday nights with my other Seca 900 and it's way brighter than anything I've used before (I've ridden the Arc Li-Ion and several Stella products).
For my Foo brethren, $250 local pickup, $260 shipped (or if the shipping ends up cheaper, I'd only charge actual shipping).
