How to choose a night headlight
Match the output to the darkest part of your route, not the average. The NiteRider Lumina’s 1,200 lumens and the Cygolite Metro’s 1,100 are both firmly in see-the-road territory — enough to light an unlit street or a bike path at a sensible commuting speed. The Magicshine URBO FL takes a different approach: its cut-off beam is shaped so the bright part lands on the road, not in the eyes of oncoming riders and drivers, which makes it the considerate choice on shared paths and lit-ish streets, at the cost of the raw punch the other two throw down a black trail.
Then check run time against your commute. Every light quotes its longest runtime on its dimmest mode; what matters is how long the bright steady mode you’ll actually use lasts. The Lumina’s OLED screen shows exact remaining minutes, which takes the guesswork out of it. Water resistance is worth a glance too — all three are rated for rain (IP64, IP67 and IPX6 respectively) — and if your route is mostly well-lit streets, a lower-output be-seen light plus a good rear may be all you need. Our be-seen vs see guide explains where that line falls.
One brand note worth having before you order: the two makers who dominate this category argue for completely different things, and only one of those arguments is about output. We put them head to head on Cygolite vs Magicshine— lumens and an IP67 body against 48 grams, a cut-off beam and lights that switch themselves on.
