Fenix LR50R - Intelligent Brightness Downshifting Sensor; Intelligent Protection; Low-voltage Warning


IntelligentBrightnessDownshiftingSensor
Theflashlighthasabuilt‐inintelligentsensingcircuit.Whenthelightsurfaceisclosetothelighting
object(about60mm)formorethan1.5seconds,theflashlightwillautomaticallydownshiftthe
outputleveltoEcotoavoiddangercausedbyhightemperature.Whenthelightsurfaceismore
than0.8secondsawayfromthelightingobject,theflashlightautomatically recalls the
previouslyusedoutputlevel.
*As objects of different materials and colors reflect differentlytolight,therewillbeslight
deviationsinthesensingdistance.

Time‐limiteddownshift 
Withthelightswitchedon,ifTurboisbeingselectedforover20seconds,thelightwilldownshift
untilto8000lumenswithin60seconds.
Withthelightswitchedon,ifHighIIisbeingselectedforover60seconds,thelightwilldownshift
untilto4000lumenswithin60seconds.
Note:Theabovementionedfunctionsarespeciallydesignedforavoidingdiscomfortanddanger
causedbyoverheating.

OverheatProtection 
The light will accumulate a lot of heat when used on High I, High II or Turbo output level for
extendedperiods.Whenthelightreachesatemperatureof60°Cor above, the light will
automaticallystepdownafewlumenstoreducethetemperature.Whenthetemperaturedrops
below60°C,itwillthenallowtheuserforthereselectionofthosemodes. 

Low‐voltageWarning 
Whenthevoltageleveldropsbelowthepresetlevel,theflashlightisprogrammedtodownshiftto
alowerbrightnessleveluntilEcooutputisreached.WhenthishappensinEcooutputmode,the
batterylevelindicatorblinkstoremindyoutotimelyrechargeorreplacethebattery. 
