    Coffered Ceiling Lighting

    Anyone ever install lighting to light the top edges of a coffered ceiling? Wondering what type of lighting one would use. Some type of LEDs is what I'm leaning towards. End result something like this:

    In the 'old days' (ie about 10 years ago) the answer would have been rope lights with incandescent bulbs. Infinitely dim able!

    Now, you can get LED strings with multi-color LEDs so you can pick your color. Most of these are about 3/8" wide x 16' long, with a peel-off strip on the sticky back.

    Search for >LED strip mounting channel<. There are varieties at 45* angle, a U-channel to embed in drywall (fill in that decorative expansion joint), and curved strips to gracefully light the wall. Most are aluminum; some have clear or translucent covers strips.

      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.

        Also look at GM lighting here: http://gmlighting.net/

        There are even edge-firing LED ribbons available.

        You'll need to pre-wire and coordinate with the carpenter.

            superbrightleds.com is what I’ve used. Their prices are extremely reasonable and if you send them dimensions, they’ll put together an order for you instead of you spending an hour on their website trying to figure it out.

              I'll take a look at all of the links. What is typically used to hold the strip in place? I cannot see adhesive tape lasting very long.

                It does, but if it doesn't, contact cement works very well. I even use it to affix wiring under cabinets.

                  I took a look at those, look nice but my head is spinning.

                  What color would one normally use for coffered ceiling lights, I'm thinking 2700 or 3000K.

                    For coffered lights, I'd go with a 'tunable white.' No telling what everyone will like.

                    Better, go for the color + tunable white. Mood lighting in red, green, or blue!

                    Blue-- reminds us of the moonlit night we spent on the beach in Acapulco...
                    Red-- reminds us of the lights on the cop car when they arrested us on the beach in Acapulco...

                      DiodeLED is what I use to.

                      It's a little more pricey than the other brands but it's definitely a great product.

                      A basics 100 will work for accent lighting.

                        The double sided tape works very well in 90% of my applications. However DiodeLED has tape fasteners that hold the light in place.

                            I'll take a look at that too, thanks.
