I'm currently playing with an idea to convert my living room and family room to LED lighting, however nothing on the market fits my needs so I'm thinking of a homebrew solution. I want to use a computer power supply or other stable 12volt source and then build a current regulator/dimmer possibly tying into X-10 control. My question is this, does anyone have any experience with permanently installed LED lighting? Is making a homebrew power supply/controller reasonable or is it more trouble than it's worth? Is this something I am going to need to rip out if I decide to sell the house? Any recommendations on circuit design? Thanks in advance!
