I'm planning my first rgb setup for 2020 and I would like to make the lights permanently mounted. I plan to install the rgb light 'strings' behind the fascia board for uv/weather protection in CA. My question is, what is the best material to do this with? I was thinking a vinyl siding j-channel, not sure about rigidity with all lighting/wiring. It would be removable, just not removed after each season, 2-story house. 2nd question is, how much needs to protrude below the fascia board? I was planning to just let the tip of the bulb stick out. Is this enough? While here, can all the injection wire run in this channeling as well?
