Hi freeme. It would be nice to have in the OP a retail cost for the light for those of use who have to base decisions on cost. I don’t know weather this is a $100 retail light like zebralight or a $50 light like skilhunt.
That being said: Gearbest is selling this light for $49.95
I have the Imalent DM 21 and especially for cycling, LOVE the rotatary switch and think this implemented in a headlamp is awesome! I’m not so much of a fan of the PWM the DM21 uses in the lower modes though so am eager to see if that has changed in the HR20 .
