In the last ~10 years we've experienced a revolution in light-making via LEDs & high-tech batteries. I'm gonna guess that most of the (non-German) lights designed during this time were designed by electrical/electronic guys and gals. They've pushed ever more photons out of the LEDs, put something reflective behind them and a window over the front and called it a headlamp. Now that abundant photons are becoming a commodity, I'm guessing in the next phase of the revolution companies will distinguish their products by re-introducing optical designers to their teams. Perhaps it's already started: I see Magicshine - yes, even Magicshine! - is advertising a rudimentary lens rather than a plano on the front of their latest bike light. Maybe in a few more years the industry will tame those rampaging photons into intelligently designed beams pouring forth from highly visible, non-dazzling large diameter reflectors.
