I wanted to report back on my testing with the OEDRO and Hikari bulbs. I kept the OEDRO in the driver headlight, and put in a Hikari bulb in the passenger side.
It's very difficult to take good pictures of beam patterns (at least for me, who is not a pro), but here are my impressions of what I saw:
- The cutoff was basically the same with both bulbs. About the same amount of light bled up above the cutoff. This was disappointing, as I was hoping that the Hikaris would have a better cutoff.
- The Hikaris are noticeably brighter, consistent with what Tony measured with his lux meter. On the one hand that's good, on the other hand, I thought the OEDROs were bright enough, so I'm not sure I need more firepower. The Hikaris were also a bit more white, making the OEDRO look a little more yellow/green.
- The Hikari has a more concentrated hot spot, which projected forward like a laser beam, compared to a more uniform pattern of the OEDROs. I really did not like that. What I found as I was driving was that my eye was drawn to the very bright spot where the Hikari hit the ground, which is distracting. I preferred the uniformity of the OEDROs.
So, my Hikari kit is going back to Amazon; OEDRO is the winner in my opinion

Here are the shots of the cutoffs on the wall. First photo shows that the Hikari is a bit brighter:
This shows a comparable amount of light bleeding above the cutoff:
And here is the pattern on the ground, where you can see the laser beam pattern on the right side:
