The LED chip
Each light is an RGBIC-RD LED-a small chip that can be told to be any of 16 million colors, individually. The 'IC' part means each LED has its own tiny driver, so the system can run a gradient or animation that flows pixel by pixel instead of one solid color across the whole house.
The aluminum track
The LEDs sit inside a continuous aluminum channel that's screwed into the soffit substructure (same anchoring as your gutters). The track is color-matched to your trim-white, bronze, brown, or black-so by daylight you basically don't see it from the curb.
The aluminum part is rated for life. The LEDs themselves are rated 50,000+ hours, which works out to about 17 years at 8 hours a night.
The control box and app
A small weatherproof box mounted near your main electrical (usually inside the garage) sends data to every LED on the track. It connects to your home Wi-Fi and pairs with the app on your phone.
From the app you pick a scene (Christmas, Halloween, warm-white, game day) or schedule it. You can also tie it to Alexa, Google Home, Control4, or Nice Elan.
Why it survives Fresno weather
The whole assembly is rated IP67, which means dust-tight and submersible. Tested -40°F to 140°F. Engineered for the 115°F summer days and the rare Sierra winter-well outside Fresno's worst weather.
