LED lights today are getting brighter and brighter; smaller and smaller. But is brighter really better if the quality of the light is compromised by outdated focusing technology? Is a smaller frame enough, or should it be a smaller frame that can be operated with only one hand? How about beam distance and run time? Warranty and materials? While most light companies want to tell you about their quantity of lumens (brightness), we’d like to talk to you about our quality. We’d like to show you the difference between bright and clearly brighter - what it means when your light is a German engineered Ledlenser.
