As for how the light acts when the batteries are low. THAT is very simple. The light remains identical to what is shown until they blink out as if someone shut off a switch. My lights lasted a little over three hours on the high setting. For my current commute, that means I'll be charging them once a week. The low setting is MUCH lower. The low setting is about the same as the high setting on the Planet Bike Blaze 2w light. I think one reason they LOOK exceptionally low is that the high setting is so bright.

I Typically Aim the P7 a Bit Lower So as to Not Blind People
