The new BMW GS1200 comes with an LED headlight option, and I think a Ducati does as well. BMW has experince with the HID headlight in the 1600.
The lumen output seems to be close to that of a 60/55 +100 or +120 bulb, so it is nowhere near the light output of HID. I would like to see some examples of the beam pattern before and after before shelling out for the equivalent of 5 sets of good H4 bulbs.
