My setup is a departure from normal E90 LCI adaptive. Short answer is I run D2S bulbs. I have OSRAM CBI, I think but will check. I'd have to go look at my TRS purchases. That picture is from before i converted over to D2S. I run old school Hella ballasts that have been modified to output 50W per side. This was the motivation to switch to D2S.
I went out in backyard last night (bright street light in front where the driveway is). I shot toward back fence~ 50 foot distance. OMFG, i see a way different and wide cutoff with nice blue cutoff in central area. Very sharp and bright. I'm working on another pair of projectors now as i found them cheap on ebay. It is rare to be able to find projectors by themselves. I got more clear STi-R lenses and waiting on adapter rings to be 3D printed. EDIT: Yes, OSRAM XENARC 66240 Cool Blue Intense (CBI) |

The tab softens the cutoff. After trimming otitis gives you a sharp cutoff line. As for focusing I'd get the tuning kit from retrofit source. They are basically ring shaped spacers that you stack to get the focus you want. I personally put the headlight housing (minus the lens), and left the projector assembly loose so I could just plug it in and try it, then add/remove without full install/disassembly every time. If I remember correctly I didn't use any. I did have to grind down the lens, which I made a thread about.

The E90 LCI adaptive lens holder has a weird 3 finger holding setup. The paper spacers and slightly undersize STi-R lens will fall through the holder. Thus, my adapter holds the undersize STi-R lens AND has the 3 keyways on it to be held by the 3 fingers. |

Personally, I would try option #1. Option #2 isn't a DIY, I'd recommend. I've done it and broke the angle eye rings in the process of taking the lens off. The angle eye rings are connected to the lenses. You would probably want to use an oven at 200 degrees to soften up the glue & you will need some marine type of sealant. No way would I go from Xeon to Halogen. |

The angle eye is not fastened to the outer shroud but can get hooked. I start the extraction of the lens on the inboard corner but I’ve pulled out about 4 lenses now. |

Apparently you can use a mixture of acetone and goo gone in a syringe to disolve the permaseal. Then heating makes the lenses easier to remove. Wish I had known that 2 years ago!
