Very bright. I've used it a couple of times and haven't charged it yet, just pulled it out of the box and it was ready to go. Not sure of the battery time so will just have to go with what it says in the description.
If you're using the sensor buttons suggest only if you're not moving about as they regonise doors and other such backyard items a meter away from your face and turn your head lamp in to a strobe.
It also has a strobe function seperatrly and on purpose, at full bright function which will be great for signalling. With USB charging this will go great with my crank/solar charger in my kit.
