I bought an XML-3 mostly for the extended run time at lower settings. But the damn thing throws light everywhere. I'm illuminating the tree tops when the main patch of light is ideally positioned on the path. Definitely not very friendly for other road users.

I recently got an IXON IQ Premium, and despite a much higher output than the old model, still has a pitifully small lumen output. It would be nice to see a high power shaped beam light. I'd contribute to a kickstarter for one if someone was going to design something non gimmicky. Good lens setup, 500 lumen range and uses plain old protected 18650 batteries.
