If no setting is explicitly named, the values for luminous flux (lumen/lm) and luminous range (metres/m) refer to the brightest setting and the values for luminous duration (hours/h) to the lowest setting. A boost function (if available) can be used several times, but is only available for a short time at a time. In case the lamp is equipped with coloured LEDs, the measured values are given with white light or the white LED. If the lamp has different energy modes, the "energy saving mode" is the basis for the measurement.

Transportsperre

Leider funktioniert die Transportsperre nicht optimal.Durch Druck auf die Sperrplatte läßt sich die lampe einschalten,was eigentlich nicht sein sollte.Wenn man, wie ich mehrere härtere Gegenstände (Autoschlüssel,Taschenmesserchen,etc.) in der Hosentasche hat,kann es passieren,dass die Lampe angeht.Mir ist das jedenfalls schon ein paar mal passiert.Man merkt es aber sehr schnell,denn die lampe entwickelt eine starke Hitze ,was äußerst unangenehm ist.Ansonsten ist es eine tolle Lampe.
