I think I’m about to mix emitters on a Noctigon triple, and drive them in parallel from the same cell and driver. Has anybody done this already? I just want to make sure it isn’t a really dumb idea before I go through all the build work.
can’t really answer your question, but I have a bug-eyed zoomie where i have mixed an xp-g and one xp-e emitter.
I’ve done it with MT-G2 and XM-L2.
Here’s my thread if it helps you.
It also has current readings taken at the emitters.
I also did a mod with two MTG2 and two XML2
In electronics theory, an unmatched resistance wired in parallel will pass more current through the lower of the two resistive loads. So as long as the least resistance can handle the current it will work.

The XP-L emitters will draw more current than the XP-G2 emitters due to the higher forward voltage of the XP-G2. Using one XP-L and XP-G2 (to keep things simple) and using 6 amps (as an example) I predict that the XP-L would get about 3.5 Amps and the XP-G2 about 2.5 Amps — and yield about 1440 and 880 lumens respectively. That’s based on my ability to eyeball some graphs look for where the sum of the currents equals 6 and the forward voltages are equivalent. That second part is the thing that physics insists upon.
That doesn’t sound like too bad of a result, thanks for running the numbers.
