Tim, sounds like some very cool plans for your room. But it sounds like you have a bit of the cobblers children syndrome, being barefoot and all
You are correct that cove lighting with no apparent source is quite nice. And I’d love to know more about your new flush fixture, PM me with info if you’d like.
The EL under the valance is invisible when off (that room is so frigging dark, it’s hard to see anything
), and when on, is just a soft glow with no apparent fixture
I also use some CCFL's (2' long) in various colors to backlight artwork or custom tables elsewhere in the house, and mount them such that they are invisible, all you see is the glow.
BTW- Have some Cooper products in the house, nice stuff. When will your track heads include stuff like Z-Wave or insteon so I can individually address each head and make it do great stuff?
