Had an issue with the first unit batteries would drain overnight

This is bright enough to light any road runwalk but is not bright enough for trails to be navigated comfortably

The low battery light comes on after only two hours of use

The sequencing seems a bit confusing and inconsistent

Unfortunately while i found the features of this headlamp to be quite impressive the battery life claim is extremely deceptive to the point that im amazed it is legal for them to claim such ludicrous run times

Once you hold the button in the light starts at the dimmest setting and continuously scrolls up and down through the brightness spectrum until you release the button

While this setting is useful i have two issues with it first the light scrolls way too fast making it difficult to choose the proper setting

The first major drawback of this light is not really an issue with the light itself but sleazy marketing tactics dealing with the reporting of battery life
