Just curious about the frequency of the diodes and do they pulse simultaneously? Quite often I can perceive flicker in moving objects indoors.

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.

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

Didn’t realize how they actually function, looks like I need some new lights.

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

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.

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