Very good lamp. Its shade is rather yellowish, most likely lower than 3500K. I imagine that most people (myself included) are satisfied with it because it has very good light at a very good price. I have tried PHILIPS, OSRAM and others at prices (per pair) from 7-30€, and personally I consider this one the best purchase.

I don't know why there's such enthusiasm... these are the classic bulbs with the classic yellow light that all cars used to have. Nothing to do with white light. In one headlight I have put this one and in the other I have an old Osram 55w and the color is identical.

The bulbs are excellent, bright.
The problem was that due to the 100 watts, the car's computer showed an error.
So I would say there is a chance it will show an error in other models as well.
I have a 2008 Ford Focus that requires bulbs up to 55 watts

Installed on Kawasaki Z1000 MY07.
Beam: completely straight
Intensity: unexpectedly strong
Temperature: Towards white but not like LED, roughly somewhere between 4000K and 5000K.
VFM: If it cost four times as much, I believe users would be raving about their choice... At €3 you can buy it with your eyes closed.
No fans, no burning of the headlight, no blinding of oncoming drivers, they don't protrude so the headlight cap fits back on.
In summary, the old familiar halogen that shines very satisfactorily with zero problems.

I put them on without really believing that they would last because they are very cheap. Almost 3 years and they still work fine.
