mood lighting

Room and Board has a nice selection of lighting, which you can see here. Not cheap, but nicely designed and well made. Many of their table and floor lamps have built-in dimmers, which is good for "mood" lighting.

Keep in mind that lots of folks complain that dimmers put noise on the power line, which can find its way back into the system. I myself have never noticed any degradation in sound quality as a consequence of using dimmers. YMMV.

There are many respectable solutions to choose from. Try walking through thr lighting dept at Lowes and Home depot or your favorite local lighting center. You may be interested in spot specific lighting which uses battery power and can be placed anywhere you need it as long as you have a surface to adhere it to. I have found this to be very useful in my set up, just a tap and you have instant lighting of various watts to accomodate your needs. The battery power has no ill effects on sound or powerline noise. (use rechargeable lithium batteries for value)
Great for task specific needs. Look also at track and rope lighting solutions for something different.

The glow of my Cary monoblock tubes(12), and Synergistic Research active shielding LEDs(8), is all I require, to set the mood for music listening.

Best to listen in the dark, no visual distractions. When you can't do that, just use 'peepers', like from a sun tanning room. You will be surprised what 'blackness' does.

I have four ceiling cans on a dimmer and just added some halogen track lighting specifically for my audio rack. The track lighting is on its own dimmer. When I listen to music the ceiling cans are off and I adjust the dimmer for the track lighting to match my mood.

The dimmers are on their own breaker.

Funny, I just realized that I have no room or place in my listening room for a normal lamp.

The best I've found is the Orgel Vreten floor lamp from IKEA. It's 61" high by 10" square and costs a mere $19.95. There's also a table lamp version for about the same price.

Maybe a little extreme, but LEDs are pretty cool, just updated my system in virtual systems after installing some...they look pretty cool...

I just purchased a turntable/stereo LED floorstanding light that is really nice. It's made by Koncept and it not only disapears above your rack it has adjustable light levels. Google Koncept for details. These are really nice.
