ime - The better designed a non-adaptive unit is, the worse it gets.
Most LED lights have a very aggressive light/dark cut off, because it is possible. This accentuates the light dipping the wrong way in corners. No problem if you can ride on main beam, but here that is near impossible.
LED's (homologated ones anyway) are not actually brighter than Halogens - they are specc'd via ECE-113 which is identical for both technologies. ECE is not EU. They are a bluer white usually (5000K) and better controlled on the whole. So all the light goes where it should - the result - marked light/dark cutoff - perception of brightness changes.
I do like the DRL on the Triumph unit.
