Best brightness bang for buck - Packing 400 lumens into an extremely compact unit, the Lezyne Mini Drive 400 features what it calls a MOR (Maximum Optical Reflection) lens to focus every lumen into the best possible beam pattern. Side reflectors help other road users see you when the light isn’t painting in their direction, and the CNC-machined casing does well to dissipate heat and resist the elements.

The Lezyne is perfect for daily commuting through towns and suburban environments with a few unlit roads...It's reasonably priced and packs a decent punch. If you just want a compact, bright and easy to use light for daily commuting in urban settings, it's easy to recommend.
