I've got the V11R but not the Quark. Judging from reviews and from the size of the lights, I'd expect the beams to be similar (just a guess). The Quarks seem to be brighter then the V11R.
I only have the Quark, but the head shape and orange peel reflectors look very similar to each other. The V11 should have a slight wider diameter, meaning a bit more on the throwy side, but I venture to guess it would imperceptible.
