retrofit MR16 GU5.3 LED spots 12VDC Constant Voltage for usage with PWM dimmer

[Gast]

Just like dimming LED strips, I would like to use PWM dimmers to dim MR16 GU5.3 LED spots.
As most of those retrofit spots now have built-in electronics to make them 'dimmable' via classic mains dimmers, they do not work for PWM dimmers.

So what I would need is simple cheap 'non-dimmable' 12V LED spots, with no built-in electronics except for converting AC To DC, that work on a 600Hz PWM DC signal.

Does anyone know which brands/types might work?

To many China no name brands out there!
Order the products you like and test them. Return them if they don't fit.
Also, in a real store it is usually no problem to buy the LEDs for testing and return them if they don't fit.

Hi Philip,

i tested a bunch of MR16 but only the Philips Master LED worked properly (no noise, dimming range OK)

Osram Parathom Pro - dimmable: noise in dimmed state
NoName - dimmable: Noise and bad dimming range
NoName - only with PWM dimmable: little noise and bad dimming range

I use the PROLED 3ch PWM Dimmer. PWM frequency is unknown.
