Sorry I didn't reply to this earlier, I must've missed it... Anyway, to answer your question, its not so much about the output. The output won't really change much, the big thing is the clarity of the cutoff line at the top of the light spread. Its hard to take photos and capture the cutoff, but its very noticeable when driving, and to answer your question, yes, it is much better. The AL lenses are sort of 'frosted' and that makes for much less of a cutoff. With the ZKW lens, the cutoff is literally a razor sharp line...
