LED dimmable lights in audio room?

I use Philips Hue lights through Wifi in my room and haven't had any problems---they were super easy to install and give off very cool effects. 

I've used leds with both dimmers and sound activation. None of the buzzing, humming I get with dimmers and incandescent bulbs. There will be rfi emanating from transformer/power supply, move it away from sensitive audio equipment. I often take measurements with my Trifield meter, certainly many pockets of rfi, some comes from audio components. I see quite a bit from linear power supplies. As Carbonmiller stated, you'll never be rid of rfi.

The problem with dimmer switches is that they control the level using pulse wave modulation (PWM). The circuit is rapidly switched on and off to modulate the amount of power passing through. This generates a lot of radio frequency noise.

Lutron (a manufacturer of dimmer switches) has this note about using a filter to reduce RFI noise: https://www.lutron.com/TechnicalDocumentLibrary/360484.pdf

I always listen to music with the lights out… just because it allows better divorcing of the soundstage from the speakers and closer emotional connection to the music. I never thought of LED and dimmers… diodes… they sound like they would be noisy.

Carolkong, no problem at all. I use dimmable LED strip lighting in my hi fi cabinet. You can see it on my system page.
