All sorts of different brands offer lights that'll work for urban commuting. Ravemen, Magicshine, Cygolite, Lezyne, Niterider are only a few. You just get to choose how much output you want and how much you want to spend. One nice feature I like for road lights is lenses with "dipped" or "anti-glare" beams to avoid blinding oncoming traffic. I know several Ravemen and Magicshine (and even cheap Chinese lights like Astrolux) offer this. Beyond that you can get as fancy as you want - day time running lights, light sensors for automatic turn on and dimming, etc., but basically you just want enough light over a decent runtime in a beam shape that works for you. Many different lights can provide that.
