Yes and no.Do these act like normal projector lenses with a sharp cut-off line, in that if you are leaned over hard into a corner, you have no illumination in the corner?
There is a very sharp cut off - But it's basically 4 different lenses in each unit - each designed to put light somewhere different. No cut off plate as in some projectors - It refracts all the light it can (except optical losses) out. So it's not as bad as a simple projector (like the Triumph fogs).
But yes there is room for improvement. I'm really fussy about lighting and Optics in general - always have been. I'd make my own adaptive arrays ( a bit like the new Audi lights) but they'd never get past the cops at road checks. If we had 7" lights - and in the US - I'd look at the Trucklite Gen2 lights. But 5&3/4" and e-marked limits MY options.

Actually you'd probably get more light on the tarmac with 35w 5&3/4" sealed beams than a 5&3/4" with a 60/55W H4. The filament position is simply not deep enough into the parabola of the reflector.
But then again any GOOD normal reflector/refractor light has a sharp cutoff too these days. Here anyway.
They are fussy to set up. 1º makes a HUGE difference
All in all I'd rather use these at night than the Triumph lights, Wayne. In fact I was reluctant to use the original lights at night even with relays etc. Nasty dark patches at mid distance in front of the bike and masses of scatter. Worrying even on motorways. I can take my local alpine roads now at over the legal limit (which is 60mph) with no problems. I'd not go much above 85mph on them in bright sunlight. With the OEM's - 50mph tops.
