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.
