The Fenix TK41 is the lamp for everyone who wants to illuminate the area in the distance or need. Despite the light intensity the lamp is still quite handy, no comparison to the large MagLite that can be used as Verteidungswaffe yes. In addition, the MagLite not bring in this approach brilliance. The non-adjustable focus is held so that a light core selectively irradiated to him but not the absolute darkness prevails, but with the quasi stray light still sufficient room is illuminated. The light intensity can be adjusted in four stages according to circumstances, which helps to save batteries. About two switches the lamp is controlled: the right for "on" and "off", which is always the light output will be turned on, which was last used. About this right switch can also be strobe and SOS function activate. The left switch is responsible for the light intensity. Thus, continuous light, strobe and SOS function can be combined with the appropriate light intensity. Quick and easy. The luminance of a single CREE LED is overwhelming. Certainly the price is not necessarily to be understood as a special offer, but is worth the money the lamp. Unique buy recommendation!
