Triple XML / FM 3 inch head

[Chodes]

Success! 0.1uf cap across switch contacts (driver end) for debounce and I can now use the menu.
100uf cap across +/- (again driver end) also. George said sudden current at high may be tripping protect cct on cells but using IMRs or Samsung 20R unprotected so confused about fix, but happy!Set max drive current to 5 Amps, ran for 5 mins, got hot but that's expected for a 55W LED light
Finally, time to fit reflectors and turn this giant mule into what it should be.

Nice! Yeah, decoupling and debouncing are always good when there are control electronics around large currents, as voltage and current spikes and fluctuations are imminent. Did you say 5 amps for each LED? Surely that's going to cause damage/long-term degradation?

I think 5 Amps should be OK. LEDs are direct bonded to copper stars, beefy sink and body.
As the stars are screw fitted, real easy to swap out if needed.

Any updates?

Yes. The update is this project killed my enthusiasm for light building.
I will offer this for sale as an incomplete project.
(replace 1 LED and it's right to go as direct drive)
