As mentioned in the answer to this question:
we can't trust a LED driver / LEDs to be dimmable if it doesn't say so explicitly. However, only some companies offer explicitly dimmable LED products, while for others it's not clear whether they only make non-dimmable LED-related products, or whether they just don't bother with it and hence don't certify anything as dimmable.
My question: Suppose I have a LED driver, driving an array of LED bulbs/units/whachamacallit which take DC. Is there a way to safely (or with-low-risk) experiment with dimming it?
If so - I'm willing to get relevant custom equipment provided it's not super-expensive.
