For those that are interested I found this video. There is a load more on youtube but this was the best so far. The OP sign pictured looks like acrylic with black trim cap to contain the led strips, mounted with standoffs right to the wall. I am assuming the wiring is behind the white channel to the upper right side of the sign, possible power supply tucked away in drop ceiling. My only question is how do you handle the customer being able to turn the sign on/off. Remote LEDs? [video=youtube;SaG-NQ64540]https://www.youtube.com/watch?v=SaG-NQ64540[/video]
