We use constant current reduction dimming so there's zero flicker!

That’s great to hear and a big plus, but I’m actually curious about the undimmed full brightness refresh rate of the LEDs.

[drum55]

If it’s constant current the “refresh rate” is infinite, or zero depending how you look at it.

Have you measured the ripple on the SMPSU output when dimming?

[shadowpho]

Isn’t that less efficient in power and can have different color?

[SPICLK2]

It has to be an SMPSU in constant current mode, not a linear power supply. I'm sure it does still affect the colour, though.
