Here is quick abbreviated summary & first impression of the NEW for 2019 Koito bi-LED 2.0. It is a *fan-less* version and ever so slightly more compact. It may be difficult to see in the photos but the 2.0 has a slightly different beam pattern. For the US version they have shifted the peak intensity right over the 75 meter test point (roughly 12-15% more intensity). What does that mean? Well, you will see farther at that angle than the previous version. They really have that peak dialed in right up against the cutoff edge. I’m talking maybe around half a degree under. And while far distance vision has improved, the center vertical test point at 50 meters has gone *down* in intensity. This is a bit of a bummer as I would have liked for Koito to at least mirror the same performance at this test point as the previous version. None the less there is still plenty of intensity at centerline.

Width is still good for this LED projector with no apparent loss on the edges.

The lens appears to have a somewhat odd shape. It is not a perfect semi-sphere. At certain angles when the light hits the lens (to my eyes) the top portion looks as if its indented slightly. It's hard to describe. I don’t believe this be stylistic in nature so I’m assuming it's an optical characteristic. It is also shorter in its peak than the previous version.

High beam shape is nearly the same as previous version while being slightly different. I have not yet measured intensity for the 2.0.

The Nichia LED chip *appears* to be the same on the outside but I believe this to be a more robust version. I say this because after powering the 2.0 for about 10 minutes the heatsink body is very hot to the touch. Enough that you probably won’t be able to hold it in your hands for very long. The 2.0 runs at about 23W while the previous version was about 26W. I have not yet used my thermal imager over the chips but I can’t see that Koito designed the 2.0 to be easily overheated (especially in a controlled environment). So the new chip must be much more tolerant to heat. And this was so that they could do away with the active cooling which more automotive lighting manufacturers are moving away from. Less mechanical parts to fail.

Is the Koito bi-LED 2.0 better than its predecessor? That all depends on your perspective.

More thorough testing to come in the future!
