Hello everybody.
After testing different models of H7 and H3 bulbs, I think I can provide some information. I shared this information on the German forum also.
Here you have a comparison between
W5W T10 Philips X-tremeUltinon LED 4000K
H7 Osram High Breaker Laser Next Gen 64210NL
H3 Osram High Breaker Laser Next Gen 64151NL
VS
W5W T10 Philips X-tremeUltinon LED 4000K
H7 Philips LED Ultinon Pro9000 HL 5800K
H3 Osram High Breaker Laser Next Gen 64151NL
Side by side comparison:
The pictures were taken with a OnePlus 5 in manual mode with the same brightness parameters for both recordings. Same ISO 100 and 320, fixed white balance at 5800K, 1/13, f1.7.
I'm sorry I don't have any better wall to take pictures. My neighbors' parking lots are all occupied.
During the measurements, the vehicle battery voltage was kept as stable as possible using a CTEK MXS5.0 battery charger.
Note that I personally didn't like the 5800K white as I'm more for the 4000-5000K ranges. The lighting is a little better than the Halogen H7 64210NL even in rain and fog. Let's remember that these lamps are also illegal in my country (Spain), but the light cut is even better than on the H7 64210NL (carefully regulated before going out to the public roads). Testing with another car I do not appreciate any kind of glare, of course this is not an excuse if the law enforcement officers decide to punish me (200€ in Spain).
The consumption of these lamps measured with an ammeter is 17-19 W at 14.1 V. The lamps remain completely cold even after more than 1 hour of operation. This can also be a problem in countries with particularly cold climates due to the accumulation of snow. On the other hand, we have a significant reduction in power consumption. I also have all the tail lights, brake lights and plate lights in LED (red / 4000K). I can share more details of tail light/brake lights and plate lights if someone is interested.
I hope this information helps to somebody interested on improve the light output and the fuel consumption at the same time.
Greetings to all.
