I love the concept: the lamp is sold with two LR6 batteries and is ready to use, a very good point I unpacked, I just struggled a bit to put the batteries because this is a lamp that is water resistant, so it is designed to be well protected I TURN day and already I could see that she lit dramatically I never had lampeà LED, what intensity !!! At night it is obviously more impressive depth lighting and white light (so far from my old flashlight yellow light) I love the beam principle can illuminate or widely, drawing a little on the neck of the lamp, the beam is reduced and flash more intensely a smaller radius, great idea when looking for something at night The lamp is not too heavy I like the strap She seems very solid I recommend very strongly, outstanding quality (do not direct the beam into the eyes, it is very blinding!)
