Excellent and powerful portable LED lamp. I am very satisfied.
It has a button to activate the two long-distance light beam intensities (medium-cool white light) and another key to activate two other short-distance light beam intensities of fixed cold white and also colored (red / blue flashing) colors.
The long distance white light beam is very powerful, I can illuminate at a great distance like 100 meters and probably even more. The battery life is phenomenal, since I bought it I have only charged it once and it is going to last a very long time (I just say I don't keep it on often). Charging times aren't super fast, but reasonable.
It is sold with a USB cable for charging, but ATTENTION you must have a USB charger because it does not have one. In a nutshell, either connect it to a USB socket (such as those on your computer) or you have to buy a special USB charger to connect to the home electrical network.
As for the quality, it looks really well made and sturdy. Even in the details it seems well cared for and not coarse. It does not overheat and is quite compact. The purchase price is unfortunately not its strong point, but if you manage to take it on offer, then make a great purchase.
