LED 7" Round Headlamp Update

I seldom see much attention here given to beam cutoff. Because most of the LED's I meet oncoming at night are horribly blinding, and I can't understand why all that candlepower is useful lighting up the air.
To each their own, and to heck with everyone else, I guess. They are probably the ones that think they own the left lane.
I installed Grote 5x7 LED's on all my trucks and I love their pattern control most, #90951-5, their price has nearly been cut in half in past 5 years.

Honestly the LED's seem to be better at not "lighting up the air", at least the good ones are. The JW Speakers and the Philips both have a very straight, horizontal beam cut off. The JW speaker LED's are mostly straight across and then tail up at the far right side, so they illuminate the shoulder better/higher without blinding oncoming. The Philips cut-off is almost perfectly horizontal, with a very sharp distinction between what's lit and what isn't. Both have a much sharper cut off than any incandescent beam that I've see, factory or not. @slantsixdan I'm sure would have a better explanation.
