Already, the lamp does not work on batteries but with a lithium battery (it charges through a USB cable / micro usb). The battery has a capacity of 000mAh 2. And it's great because I can plug before use on a backup battery or charger to my car via the cigarette lighter. No need to say, damn, the lamp does not work anymore, it is Sunday and I'm out of batteries.
Because there are no batteries, the lamp is a featherweight., Only 80g. Even at this level, you will not be embarrassed. Furthermore, the elastic around the head, does not hurt and holds well.
The lamp is very easy to use: a center button. It allows you to access multiple modes.
Already, you have 2 mode LEDs that goes from 4 to 120 lumens, so you can illuminate up to 80 meters! I did the test up in my basement, no need to have a flashlight or use my mobile as a lamp, then I had a free hand and I could see very well from a distance. At full capacity, the lamp is designed to last 10 hours! You see what come.
And the least bright fashion: you can illuminate up to 6 meters but will last 230 hours!
Athletes, running throughout the year and even at night, can easily light their way!
There is a flash light mode, ideal for cycling. There is also a night mode (red light), I personally do not see what's the point and I did not manage to activate it.
An ultra positive point is that the lamp is resistant to rain (there is the small logo on the box) or that, it's really great because, you know, when you are camping and it starts raining, you need to light up a tent and there you are helped.
