If anyone is planning to go to high amps with these emitters, I’d avoid the hybrid 6v/12v stars.

Here’s why:

I don’t like the tiny traces they used to accommodate the 6v/12v configuration on these stars. They’re really wimpy and even in the 6v config much longer than they should be.
As we’ll likely never need to run these LEDs at anything other than the 6v config in a flashlight, that makes these traces an unnecessary complication.

Shorting the LED pads out with copper strips soldered across and running 10Amps through in the 6v Config I measured a 0.124v drop across the traces!
That works out to a resistance of 0.0124Ohm, really not great. We wouldn’t touch a DD mosfet with that high of a resistance for example.
at 15A it’s 194mv
at 20A it’s 285mv (you know someone will run 20amps through one of these suckers soon enough! )

Based on this, I’d say stick with the MKR variant sinkpads (only 6v compatible) or wait for a 6v optimized noctigon with beefy traces.

I agree. I had similar comments over in RMM’s sales thread, but I didn’t do any testing to back it up. MTN Electronics: LEDs - Batteries - Lights - Chargers - Hosts - Drivers - Components - 1-Stop-US Source
