An update on the review
I forgot to mention that no PWM was detected, which again is an improvement over most multiple 5mm emitter headlamps found at the lower brightness end of the market which use PWM.
Below I have a beamshot comparison between the Rayovac/Varta 5-LED headlamp (left) which is typical of the multiple 5mm headlamps, and the Fenix HL10 2016 (right) with its single emitter. It is no brainer as to the improvement in the beam quality!
