Anyone have the spec for BMW OEM Xenon HID in Lumens or fL? Also Color Temp in Kelvin?

Same question for BMW OEM LED Specs?

Would even throw in Halogens Specs for comparison.

Thx

Kelvin temp is probably around 4,300, we just won't go there for the halogens, just says it's "42". That's about all I can help with.

Yes, sweet spot for Xenon appears to be around 4200K-4300K. Above and below appears to drop Lumens.

But that circles back to how many Lumens does each of the 3 output for the definitive difference.

The Philips 85122WX is a typical OEM HID, 6000k, 2900 lumens. LED is probably similar.

As your post shows, moving off ~4250K Color reduces Lumen output around 10%-15%

Guess the real question is what Company does BMW use for OEM Xenons?

Ditto LEDs and Halogens.

LEDs are very similar in colour temp to xenons (~4300). Maybe slightly hotter.

The LEDs in the F3X aren't super bright, maybe even a bit dimmer than xenon, but they have a perfect cut-off and are very consistent so overall I'd say they're better.

Sorry for no hard facts but maybe opinions will help you out

The looks alone of the LED headlights make it better.

*sigh*

Another claim with no facts to back it up.

Based on my experience with LED (Non Adaptive) is that they are whiter than the HID, but not necessarily brighter and the cut off is not very well defined as the HID with the HID with the ellipsoid. Also they need to be aimed higher and once that happens then they become better.

There is a thread where many led owners are disappointed with their headlights are not as good as their HID in Bimmers they also own.

And I can see why! From the factory they are aimed too low and they do not project as far! Cut off is crappy and overall not as good as HID, but that is my opnion...

Obviously you are not alone.

Standard HIDs are 4300K and both of my cars had standard Philips D1S bulbs.

The thread I made here might help: http://f30.bimmerpost.com/forums/sho....php?t=1230507

Wasn't making a claim. I was talking cosmetics. Also, my friend's 428 has LED headlights, and its much clearer and more crisp than Xenons.

Does anyone know the kelvin rating for the halo rings?

This is the low beam headlight bulb in my 2013 F30 328i xDrive. It has the Xenon headlights. Not sure if this is the stock/OEM bulb but it’s been installed since I bought it in 2016.

[328dabi]

Low Beam:
F30 Standard LED: 784 lm
F30 Adaptive LED: 1097 lm
F30 Adaptive HID: 1170 lm


High Beam:
F30 Standard LED: 1226 lm
F30 Adaptive LED: 1498 lm
F30 Adaptive HID: 1702 lm

LED: 6000K
HID: 4300K

I don’t have info on the halogen F30 lights. I’m trying to find something accurate but if I had to guess the lm is likely in 700-800 for low beam and around 1200-1500 hb with a temperature somewhere around 3200-3500k. But again, these are just guesses. If anyone has accurate info on the standard halogen lights please post.

Lumens is a measure of the total light output from a bulb in all directions. That isn’t the important value.

For headlights what’s most important are Candelas - the measured ability to throw collimated light in a particular direction… far ahead down the road. And Lux, the amount of light received on a lighted surface at a given angle/distance.

So it’s about how the bulbs output (lumens) is utilized and focused by the reflector/lens (candelas) to achieve the desired level of light throw on the target (lux)…

And I’ll take my Adaptive Xenon’s over the pre-LCI LEDs or even the LCI Adaptive LEDs any night.

From what I understand the LED’s are an afterthought in a halogen housing which is why they are not as good as the projector HID’s. They are not as focused and scatter light. Similar to older non-projector HID’s.
