What is not brought out is where the light goes. It gets glossed over.

The point to focusing the lamp is to put the light where it needs to go and not into the trees or the eyes of the oncoming cars.

A while ago someone did tests with a light measuring device and found the halogen solution did put almost the same amount of light where you need it to drive. But it also put a lot of light all over the place.

Pretty sure blinding oncoming traffic or be in the mirror of the car in front is a good thing.

So a real test would be measuring the light in multiple places. I am pretty sure there are standards for light amounts in areas in front of the car.

Do these LED lamps meet these requirements when used in the A headlamps?

We do not know and likely will never know. If you are going to ask the questions you need to ask the right questions.

As I recall the original type bulb with a good reflector and properly focused did a decent job lighting the road. A direct fit halogen did better. Both work fine with factory electrics.
