led has gotten to the point of having similar overall lumens as halogen, but are still incorrect for the optical layout of halogen/hid housings, which contribute to the light scatter issue.
both halogen and hid have a light source that is very much centered within a very small area. led tech still requires a heatsink design that places the light source about 2-4mm outside of that small area. it doesn't seem like much, but it's an incredible difference when talking about a headlights parabolic reflectors that expect a much more concentrated light source at a central point.
some led designs get around this by shifting the led back or forth in the housing to account for the less than ideal placement of the larger light source end, but it's heavily dependent on the optical leeway of the specific housings. some, it's close enough, others, it makes it no better.
