The first time they adjusted them they were blinding all uncoming traffic and I got flashed by half the oncoming drivers I passed. Now they light up the road much better than they did, but I do not seem to be disturbing oncoming drivers - so it looks to be a fine line I guess.

I have 2014 with HID and a 2016 with LED. HID seems better on wide variety of situations and hence is a better choice between the 2 for me.
The difference is the projector lens vs the reflector housing. An equivalent LED behind a focused projector will have a better light throw than it being in a reflector housing. Similar for an HID as well. I think HID seems better because of it being in a projector lens housing and hence the beam is focused. On an LED the light intensity needs to be focused than a distracting wide spread and then darkness a few yards ahead. HID is focused thanks to the projector lens to get a better down road visibility. Hopefully G20 will have better optics by placing the LED in a projector housing for a very focused and deliberate pattern. I sometimes think that the new corollas with LED behind a glass projector lens do a better job at light output because of this reason than the newer LED BMWs |

I have the LEDs and the problem is when going down a hill I can't see more than 10 feet I'm front of me. They need to aim up more all the time and especially up when the nose is pointed down.
They look nice but the hids on my last car were better lights... |

Well the light housings arrived today, for anyone interested they are manufactured by Sonar (Tiawan) quality looks good out of the box, cant speak to fit yet.
Re. original question "halogen vs. LED?" the answer seems to be HID. I already knew this, everybody knows this. But if HID isn't an option, then which? Given the lack of clarity I'll most likely go with 4,000k halogens & revisit the subject in a couple years |

Color temperature is only that, the light color. Where light output is concerned H7 halogens top out around 1500 lumens, while H7 LEDs run at least twice that. There's no such thing as 4k halogens, they run around 2.5k. Bulbs that claim a higher temperature imitate it with tinted envelopes, which also reduces lumens output.

Agreed! The adaptive Xenons are the best for providing ample light down road when comparing OEM options!

Halogens have NO PLACE in a 2017! Except for the fact that it allows car manufacturers to hit a price point, the owner pays a huge price in safety with this now antiquated lighting technology. If a Toyota can put them into a Corolla with projectors housings years ago, then it's downright a travesty BMW still puts them in any of their cars.

It is impossible to produce white without Blue (or Yellow) If one takes the blue spectrum in the 465nm spectrum and the light shifts yellow in the 570nm spectrum. Remove the Yellow out and the light shifts Blue, as can be seen on the attached picture. Of course, that contradicts his statements that totally that defy physics. The only way to measure the light spectrum for color in 1nm segments would be a RadioSpectrometer, which start at around $20,000 each. Not something that a speaker designer would have laying around. Secondly, the light output in front of the car depends on multiple factors. Having done considerable tests when the OEM LED v HID v Halogen question first arose about 3 years ago, the lumens vary very dramatically with a movement of the test meter a few mm directly in front of the car. You can spend literally hours attempting to find the hot spot. That’s if you even have the proper equipment for testing properly. But testing several inches in front of the headlight really does not tell you what you really need to know - which is illumination at a distance. Without a very controlled environment devoid of any other light and the distance needed, coupled with his lack of response to the questions, make it very questionable his claim of testing....especially when he defies physics in his statements. For reference before someone asks, the lower the Kelvin, the larger the wavelength. Likewise, the higher the Kelvin, the smaller the wavelength. That explains Yellow lights at 2500K and Blue light much higher K. Before asking “but there is no White”, White is a MIX of Primary Colors RGB (or Secondary YCM). That explains why his statements of “No Blue. No Yellow” defy physics as white light needs a combination of all 3, residing roughly at 6500K Last edited by kabrichx; 11-17-2017 at 12:47 PM.. |

I've learned through experience how to recognize a troll, where the poster seems to be asking a legitimate question with good intent, but in reality is only interested in arguing, the only goal being the stoking of his ego. I don't feed trolls. I do add them to my ignore list, so don't bother trying to goad me into your game, I won't see anything you post.

The reason you didn’t respond was you knew your posts on the subject were BS. Guess you won’t see this though...only people who learned the King has no clothes. |
