Nice little light, perfect for commuting. It is anLED so the run time is over 4 hrs. Whats really great about it is that it is all in one package.. the battery is in the light unit itself and is rechargeable. It has 3 brightnesses and a flasher as well. It lasts me the month ( and probably even more ) for commuting. It also can be used as a light duty light for trail riding. It does light up the ground ahead of you somewhat but its not its main intent. I have paired it up with a headmounted light with great trail results. I bought it for about $70 on Chainlove so Im sure you can find it for a good price somewhere
