Well, considering that Dan is in fact an automotive lighting expert with expertise and job experience in the field, I would put his opinion above yours. I’m also quite sure his opinion is based heavily on actual data and is not at all “unsupported”.
There are other threads that detail Dan’s background in the automotive lighting industry, if you care to inform your own opinion.
You can also look into this thread, which has more information than the one I previously linked
