Lenses have a different height and simple geometry (the more advanced lens at right on photos #1-2 are from the flashlight at photo #3). Beams: glossy lenses gives an exact circle beam and does not have a true wide-near light; glossy lenses 30-60° and stripes lenses <45° gives many flares and show the LEDs square&legs; glossy lenses 90-120° gives the bad ring beam; stripes lenses gives the rectangular light beam, which are not comfortable for a walking (maybe will suit for a bikecycling); all matte and collimator lenses have a smooth circle beam; collimator lenses gives the most unifrom wide light area thus they require the very bright powerful LEDs. Best 2 LEDs&lenses set is 15° glossy lens for the long-distance light + 30-45° collimator or 60-90° matte lens for a wide-near light. One best universal lens is 15-45° collimator or 30-60° matte lens. Some glossy have skratches. Some of the purchased different lenses are comes identical.
