Then I'd like to put up about 8' of it under the bar counter on the home theater side. Each area has it's own outlet, which will be able to control power to with my home automation system.
The crown is 9/16" x 3 7/16" and will be nailed at the bottom of the ceiling tray/soffit, and I'm still figuring out what kind of backer/nailer I need to build to support it. I did do double drywall/green glue, including under the beam, as there was an air gap on one side, so there is no wood at the bottom of the beam on one side for 1 1/8", and 1/2" on the ceiling tray side, so I will need backer for both.
Both my areas will require at least 2 and possibly three 10M LED strips, and the home theater area has the outlet roughly at the 18' mark of a roughly 60' run... so I'm trying to figure out whether I can get away with one transformer or not. and then two runs - one longer than the other. So I'll have house some stuff up in behind the crown.
How wide is the gap between the crown and the wall in your case? How deep is it? I.e. how much room needed to hold all that stuff? I assume you have an extension cord running to the outlet, the transformer, the wiring and the LED strips in there.
How did you attach backer or the crown in your case? I was at first going to cut down 2x2s to the right angle, but now I'm thinking I may make a finished piece that holds it out from the wall to create some more room behind the crown.
Any wisdom for me?
My crown is actually FOAM crown molding, attached with nothing more than painter's caulk. It is stuck to the vertical wall of the soffit, so that the bottom edge of the molding is even with the lower ceiling.
I have an outlet in the wall right next to the transformer you see in my photo, but poor planning by me makes it so the outlet is just barely too low to get a grounded plug in there once the crown is attached. So, I had to buy and install a very short extension cord with a right-angle plug, which is inserted into the outlet. Then the transformer is plugged into that.
I'm afraid I can't recall the dimensions of the crown... got the biggest I could find in the foam product. The products just barely
fit in there.
By having two of the strips plugged into one transformer, I believe it is slightly underpowered, as I can see that the final LEDs in the line are dimmer than those up near the transformer. There's even a slight color variance between the beginning and the end. Not enough for me to care though, as my cost was so low. I would say you could never have too many outlets up there in that ceiling tray.
