The light is very useful, by forward and backward slide can be focusing, at max you can see projected the construction of the LED on the wall. Square with 8 cm edge length in 1 m distance.
In the other direction you reach a uniformly illuminated circle with 70cm diameter. Less than other lamps but quite usable. The adjustment works easily and the lamp is well made.
She knows only to and from what I consider to be positive, since you always have to Duch by switching some modes with other lamps, up simply in "just lights" is back.
The only negative point is the charger that stuck through the adapter to plug the Euro partly in the socket makes a not so safe impression, therefore deliver even a star.
