LED dimmable lights in audio room?

@mijostyn.  I like that. I have a little LED spotlight next to my turntable for when I am listening to vinyl… with a switch accessible before I get to it. 

Sometimes I listen in total darkness, have black out shades on windows. Other times I use various LED light shows (consumer editions of professional light show equipment) in concert with blacked out room, I also have turntable led light, none have created any noise through system. Place your transformers in proper place, shouldn't have any problem.

I’ve got a large room I use for 2 channel listening and my office.  Aside from listening to music I’m also into photography.  I have 24x36” prints mounted as well as concert posters I have framed etc.  To light all these I installed LED track lights that are controlled by a dimmer.  
I have ZERO issues with noise on any of my circuits and can dim the lights with zero buzzing or flickering.  The key is you need to buy a good quality dimmer designed for LED.  Specifically you want an electronic low voltage dimmer.  I bought a Lutron Maestro MAEMLV-600-WH.  This is a very expensive dimmer but is the ONLY one I found that didn’t cause an audible hum with the LED track lights I installed. There also doesn’t appear to be any sort of noise on my AC feed to my equipment, whole system sounds great.

I use philips hue lights in music room no issues at all 

Not all LED lights are created equal. My kitchen LED lights creates a lot of interference with FM reception. Putting a ferrite bead on the antenna lead 100% cured that issue. I once had a multicolor LED light strip which I fooled around with- that also caused noise on all inputs.
