all available (H7) aftermarket LED lights are crappy and have way too many issues:
- inconsistency of light pattern
- large size due to fan or fanless design
- longevity/reliability
- CANbus incompatibility
- light output and heat emitted
In addition the headlight housing you have has very limited room and overengineered mounting bulb clips which don't let you aim/adjust the bulb inside.
i myself have tried about 10-12 different LEDs and they all were inferior to the stock lights.
This is why I did H7 HID kit and i was quite happy that I did. it does not solve the problem but it's a HUGE improvement.

Original HID bulbs 4.3K provides around 110K Lux
I bought D1S - Osram Xenarc 66144 CBI HID Bulbs I think they were 6K and provided around
130K Lux
The last option I bought OSRAM Xenarc Cool Blue Boost D1S Xenon Car Headlight Bulbs (Twin) 66140CBB-HCB they are 7K and providing around 160K Lux.
My wife car has LED lights and they provide more than 200K Lux, my meter goes up to 200K and it shows over limit error.
So, Im sure LED lights should provide more lights and not all HID bulbs provides the same amount of lights.

I used light meter to measure, my ML came with dynamic HID package

Lux meters are fundamentally the wrong tool for the job of metering HID light sources.
Using a lux meter to meter HID light sources makes as much sense as timing your car's 0-60 time with a measuring cup.
Lux meters are fundamentally "blind" to automotive metal-halide light sources and you would get better results asking a color-blind person if they liked a red C63 or a blue C63 better.
