Triple would be nice with some small, flat emitters. Like Luxeon CZ or Boost HM.
But considering that the PCB is going to be custom and therefore it will be hard to convert to another footprint, 3535 might be a better choice. And it will be very very floody with any good 3535 emitter that’s available with high CRI. So…i like the uniqueness. I love how it shaves a couple of mm from the length. But I think that a single emitter would be overall a better choice.
ADDED:
I see that there’s an emitter choice posted a while ago. As expected, all options are 3535.
I would say SST-20 because it’s relatively throwy. But warm CRI-95 only, no 6500K EDC.
BTW, XP-P might be a fun choice. Though I wouldn’t pick one.
I’m already on the list, but will add my preference for the LEDs. I would love warm high-CRI SST-20 (either 2700k or 4000k, doesnt matter too much to me). I have no interest on the cool white SST-20, so if the options remain the same I would choose the Nichia 219C 4000k.
