Interesting. Thanks for that video. It'd be amazing to have access and the necessary knowledge to use that equipment. By a photo I didn't mean a photo of a cutoff against a wall, but more of a comparison of what Virgil or Daniel consider a good LED reflector vs the Retrobrights.
Virgil and Daniel do and have provided their 7 inch round lamp recommendations. They may not package that advice in a side-by-side comparison to other lamps per se which would visually show a clear "winner" because once again, the measured data is what's most important. They know that photos can mislead so they rely on the objective data to determine what is best.
What was the equipment reading? Where are the notes? How do all those numbers compare to, say, a JW Speaker of similar characteristics.
Without a proper understanding of the U.S. lighting requirements or a proper understanding of what makes a "good" beam vs a "bad" beam vs a "ok" beam or how that translates to visual performance, these numbers are just numbers to the masses.
Case in point: see below and tell me what this information means to you? What can you conclude from it?
I just can't listen to someone say "don't buy this, it's crap" and just take their word for it, no matter if they are considered deities in their field. Each use case is different.
Exactly! Which is why I've began a journey to test lamps myself. But you know what I've learned along the way so far? Sometimes we think we know more about a subject than we actually do and we insert our *uneducated* OPINIONS into a science that is fundamentally based on FACTUAL DATA. Automotive lighting is a COMPLEX subject and its not one that can be fully explained in a few online forum posts. Learning is a process and it isn't until you really do thorough research and consult professionals that you come to the realization that you've had some (or a lot of) things completely all wrong. Not saying these individuals can't sometimes be a little off base on occasion, as they are human, but you have to humble yourself. No one becomes knowledgeable without first learning from knowledgeable sources.
Daniel could recommend me what he thinks is the greatest reflector in the world, but maybe the lens turns yellow after 2 months, so what good was it that it was optically perfect in a lab? I value glass over plastic a lot and for others it may be irrelevant.
Yeah you kinda lost me here. This statement doesn't make sense. Pretty sure Stern doesn't/wouldn't recommend lamps that yellow after 2 months.
I'd much rather have 3 pages of regular folks who had actually bought the headlights and came here to share their experiences so I can mix and match what I read/see to adapt it to my needs. But apart from a few forums here and there and the aforementioned awful YouTube videos, it seems we don't have much.
Its definitely great to have a community to share their experiences and thoughts but you have to take it with a grain of salt. People can and do give bad advice. In fact most people are HORRIBLE judges of lighting. Brighter does not always mean better. Just look at the reviews on Amazon of LED and HID headlight bulbs inside halogen lamps. Hundreds of reviews with uploaded photos of headlight beams shined on a wall with garbage bulbs. Beams completely altered negatively all while being oblivious to it all. This goes for just about any other type of lamp: sealed beams, light bars, fog lamps, etc. People cannot be relied on for proper evaluation of forward lighting. I know that some just don't want to accept this as fact but its reality whether you like it or not.
