Does anyone have any suggestions for lighting setup for my new insulator room. I plan to light the 3 walls of my 13X14' room. Would like to mount lights on 3 walls to full length of the bookcases. Have the bulb and diffuser info from the various ICON info but need advice on arrangement spacing etc. I remember how great Don Briel's and others rooms lighting were and don't want to make big mistakes. Any advice? Thanks in advance.
