It is about 5.5 cm long, 2 cm wide and 7 mm high. Weighing just 11 g lightweight! That these dimensions even a battery is not integrated, is incredible. The build quality is also top, the rugged plastic housing is even screwed and not just glued. The Micro-USB port for charging the battery is protected by a rubber plug. This protection is a bit tricky to be solved, and probably holds not very long, but so far it is still in place.
The control button is rubberized, and has a good tactile feedback. Press 1 x briefly activates the weaker mode. This is already enough to find a keyhole. Press 2 x briefly activates the strong mode in which an entire room can illuminate problems. One need only times briefly light, simply press and hold the button, and it is the strong mode so activated until you release the button again.
In the weak mode, the LED can be dimmed continuously even if you hold the button down long. Once it has reached the desired brightness, you can just start.
A memory function does not have the lamp, ie it starts when pressed once more in the weak mode. That does not bother with such a lamp but no further.
The battery life is very good, and when the juice runs out but once, you can fill up the lamp at each USB port with a Micro-USB cable. There is even a charge indicator in the form of an additional small LED in the housing, the light blue. Once the battery is full, it turns off.
All in all I can find on this lamp anything negative. Buy!
