Permanent LED lighting is a strip of individually controlled lights fixed along a roofline and left up all year. The hardware is simple to look at, but the choices behind it are not: what kind of white, how far apart the lights sit, how the controller works, and how much electricity it uses. Those choices change what the house looks like every night for years, so they are worth understanding before anyone installs anything.
This site covers the technical side in plain language:
Color temperature and RGBW. Why one white looks cozy and another looks harsh, and why a dedicated white LED matters.
Pixel spacing. What changes when the lights sit closer together or farther apart on a real house.
Controllers and apps. How schedules, presets and zones work, without tying anything to a brand.
Power use. How to work out watts and kilowatt-hours from a spec sheet, with the math shown.
Holiday preset planning. A list of holidays and color ideas to set up once and reuse every year.
The pages are written for homeowners who want to read a quote and know what it means. If a salesperson says "RGBW" or "6-inch spacing", you should be able to picture the result. If an app offers a hundred effects, you should know which few you will actually use.
Nothing here assumes a particular product. Different systems use different LEDs, channels and apps, and each page points out where that matters and what to ask.
If you are earlier in the process and want to know how an install is mounted, how Middle Tennessee weather affects it, and which questions to ask an installer, start with the companion site, Nashville Permanent Lighting Buyer's Guide.
These pages come from Permanent Lighting Solutions. Permanent Lighting Solutions is a veteran-owned installer of permanent roofline LED lighting in Nashville and Middle Tennessee. We explain the same handful of technical points to almost every homeowner we meet, so we wrote them down once, in a form anyone can use.
