Updated (forgot about here).
Turns out the lenses aren't the issue, but the (suspected this sigh) bowls are 'burnt'.
I ordered some second hand OEM Maxima projectors from USA, they look very similar to these Koito ones in most Japanese headlights.
Unfortunately, those of you who have dim HIDs, you'll have to pull the headlight apart (not hard, just be patient).
Here's a comparo to my retrofitted R32 lights (same bulbs)
Look at the light we're missing out on!
