Have someone watch your bike at a distance, top of the hill, bottom of the hill, while in a corner, etc., and share the feedback. Bike movements are too dynamic to rely upon straight-on evaluations. Lately I've spent time at a large city MUP observing bicycle lights at day & dusk and poor off-axis visibility was apparent.
Gee - if you were referring to my initial recommendation about that Blackburn unit - that's a design that uses THREE LEDs across a curved front panel with individual lenses designed to make the light more visible from the sides in spite of the narrow beam. Not all these things have identical designs and the OP subsequently asked some specific questions about one light in particular that uses a single LED. My apologies if that wasn't quite spelt out clearly enough for you.
