HI everyone, I wanted to chime in here.
I've tried two LED options in my '13FFE. I first tried the fanless Phillips H11 product in my halogen headlamp. I wrote this review on Amazon:
"These LEDs have identical lumen output to a 55W halogen, but the photometric distribution is still wrong compared to a halogen filament. This translates to how well the lamp housing can collect and aim the light down the road. With identical lumen specs but poorer photometric distribution this lamp fails to project the same amount of usable light down the road. The range these bulbs cover is noticeably shorter than halogen counterparts, especially in side by side testing. Look for LEDs that produce 360 degrees of light output at precisely the same distance from the bulb base as a halogen, with better lumen output instead."
I had intended for these to go in my fog lights, but had tested them in the headlights. In the fog lights they performed a bit better, and will certainly be cooled much better. They fit in both headlamp and fog lamp just fine. They do not project enough light for headlamp usage, although the beam pattern was acceptable.
I then went the brute force way, and used the Starnil 3600 lumen 40W triple COB fan cooled bulb. With a bit of fines, they did fit in the low beam H11 sockets but I had to remove the fan guard. The LEDs operate at 160F open air and the LED driver operates 150F open air 80F ambient. Anyways, these bulbs have brutal lumen output but the "COB triad" has much worse photometrics then halogen capsules and the phillips LEDs. I end up with a very bright region close to the car but it fades quickly. There is almost zero overlap between where my high beams start and the low beams end. They are bright enough as headlamps but HID would have the closest photometric match to halogen. PS the fans are noisy, especially when you have an electric car.
The H7 Starnill product does not fit the high beam. The headlamp housing is too complicated and contorted to get this in place.
I would like to improve this system and make my H7's work as high beams... I want to get PC CPU water blocks epoxied to the LED bulbs to replace the fan heatsink, epoxy the LED driver to the other side of the water block and then run hoses to a small radiator somewhere behind a fog light with a 12V pump. Don't want to cut into my EV low temperature cooling system, although it would be ideal.
