This flashlight focus is on the move the lens accomplished. The lens is not rotated, but actually moved. Here, the focus can also be adjusted when the lamp wegpackt times and pressure is applied to the lamp. In a selective focus can be seen on the wall an image of the LED used if you have selected a wide coverage to a uniform circular disc which (in my opinion) almost brighter than when one focuses the light beam. There are three levels of brightness and twice the flashing light by simply pushing on the on / off switch can be selected. There is however no memory function, which executes the last selected option to first. The 1800 Lumen are lying, but that ye shall surely be able to think. Still, I would not want daily into the light ...
The delivery time was long since another customs clearance stands in the way. The price of the lamp and power is ok. I have to light up only slightly in the garden so that the lamp is sufficient for professional use I would buy something higher quality.
