djozz sorry about the OT.
Added one R120 for about 4,7.
Two R120 in series (on top of the stock resistor) was about 3,65 I think. Stock output on mine was quite close to 2,8 I think…
Its basically the same driver that I modded in this messy thread. But there are a few differences. If you have the same looking driver, yours might have differences too. I have not tested it for more than a short period though, so mod at your own risk… 
Edit: I have no intention of using the huge stock aluminium mcpcb in that light. Ill kinda make a cooper “pill” for a copper mcpcb to sit on… Ill might make a mod thread some time in the future…
