Common complaints
Silicon switch wears out quicklyAccess to secondary emitters (red and UV) is slow and complicatedLowest white mode is relatively bright; no true moonlight for dark adaptationNot waterproof beyond IP54 splash resistanceThermal design may limit higher mode performanceSingle button operation limits ease of switching between secondary LEDs
Limited maximum beam distance and runtime due to small sizeNot suitable for heavy-duty or tactical applications
