Some feedback on these COB LEDs:
I don't like them....
...I'll qualify that opinion slightly though! I like the colour, in fact its as spot on as we have ever seen. I like the fact they put the light out sideways so no forward firing light at all which makes them perfect at lighting the reflector housing very well. They fit, just, with a bit of a faff. So what I don't like is their length. They are too long, so long that they cause a bit of a problem. they protrude so far into the housing that they touch the reflectors and actually limit the vertical adjustment of the headlight!
If your car is stock Ti or Lusso height this wont be an issue as they don't stop it going higher that it should for you, but if your car is lower than a Ti, like mine is, you need to get the beam a bit higher and that makes these LEDs a problem.
Don't get me wrong, its pretty much borderline, but it is a problem that I need to let you all know about before you order them from China!
In terms of fitting them, I found using the additional resistors we posted about ages ago in this thread is very useful as you can tape the bulbs to the resistors to give you greater control over installation and removal. To get them out whilst installed in the car I just find the resistor and give it a tug and they come out lock, stock.
So to summarise, right brightness, right colour, too damn long!
