I took a look at those, look nice but my head is spinning.
DiodeLED is what I use to.In my view one of the best sources right now is DiodeLED. Very high quality. It takes some study to learn their different types and colors of tape, tracks and diffussers but for a quality job it is worth the effort. See here: diodeled.com
One thing you need to be careful about in an application like this is that it is designed so that the light bleeds out above the molding rather than casting a sharp edge of light that looks sorry. Also be careful to design for max lengths that do not exceed class 2 limits. Often have to break it up into multiple drivers driven by one dimmer.
The double sided tape works very well in 90% of my applications. However DiodeLED has tape fasteners that hold the light in place.It does, but if it doesn't, contact cement works very well. I even use it to affix wiring under cabinets.
I believe the image in the above post is from a project by Troyer Builders of New Orleans:How can I find more photos of this home? We’re building and I love the layout. Is this something you found on google or do you know the builder?
