I've just installed a Schmidt Edelux headlamp on my Cross-check in parallel with a LightOn! Headlamp. They're both Led lamps. The Edelux is a single emitter that is focused with a shaped mirror to create a tight box beam, the LightOn! has two emitters with small parabolic mirror and lens that make for more of a flood even though they say it's a 5degree beam.

It's so obvious that the shaped beam can light the road 50' ahead and the flood can't that it makes me wonder if any of the battery powered systems have shaped beams with distinct cut-off so you don't blind others but equally important use available power efficiently.
