75 is lumens outright dishonest marketing my opinion says. Judging by my Q3s and comparing them against other lights I own, I'd estimate 30-35 lumens. For example, both of my Q3s light up a room to much greater effect than my Streamlight Luxeon Jrs (rated at if I remember right 30 lumens). Different type beams might also account for this, so I'd say the Nuwai could be as low as 25 lumens .
