This flashlight is relatively small, but with good light output. The light cone kan focus you, so that you either illuminates a large area or a distant object. 400 lumens might be a bit exaggerated, but for normal home use, it is sufficient. Unfortunately, you can not save the last Einstllung, so you have to always zap through all 3 settings. Flashing probably just needs a professional burglar to irritate (And then there's true failed ling anyway a professional lamp) as Privarverwender is unnecessary and only connected to another Zappvorgängen.
