If you are getting flicker I would try swapping dimmers.
Very impressed with the colo{u,}r purity
You can disconnect the transformer and power with 36v DC. Dimming works well with a PWM Meanwell dimmer (0-10v input)
If you're like me and want to avoid proprietary/locked-in stuff, highly recommend doing the 0-10v thing. Your control system is then separate from what drives the lights
On the things I have been able to measure (flicker, colour spectrum) they cost about 1/3 of lights with similar quality.
