    Cutter-4N + Cutter-XPGMR11Q

    Guys, I have seen that someone used this combo with a very good result. But XRE optics sits higher than XPE:



    Please comment on this.

    Cut the legs down, so the optic sits on the leds

    It would be difficult to position the optics right if I did it. I have a better idea to cut cavities for the legs in the plate but I would like do know what people already did with this.

    Maybe you could also enlarge the positioning holes in MCPCB a bit, so that shortened optics legs would fit?

    Probably for the same reason: XRE optics sits higher than XP.

    The Cute3 I'm using on my XPG triple is actually the XRE version and has a similar gap to your picture. I was using XRE before upgrading to XPG. It may be slightly suboptimal but works fine as is.

    The tests I did on 35mm quad vs triples using a light meter showed that you don't really get much benefit to the quad over the triple. The smaller optics in the quad and the lack of a true 35mm XPG optic means you lose efficiency. So you end up using more power for very minor improvements in brightness. You can look back at old threads I started if you want to see details.

    I also did some tests of the GT4 optic which is pretty much a flood. And if you want a flood, it's actually pretty impressive on the quad 35mm XPG board. I think it makes a very nice bar light if you mostly ride tight twisty trails.
