LED dimmable lights in audio room?

@ghdprentice, I do all my serious listening with the lights out. Visual distractions interfere with the image. However, It is hard to change records with the lights out. With LEDs you can put the light where you need it and avoid lighting up the whole room. The switch for the lights in my cabinet is right next to the turntable. The power supply for the lights is mounted behind the cabinet and does not cause any problems.

@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
