for others. I’m not a good judge. It was a lot of fun but also a lot of work.
LEDs: WS2815 LED strips from BTF Lighting ordered directly from China through Ali Express. I got the IP65 waterproof with 30 LEDs per meter. I wanted 12V to make the voltage drop a little easier to manage.
Controller: I bought 2 DigQuad controllers from Dr Zzzs (a youtuber in Utah). I just use the open source WLED project for the software. There are more options available now at dr zzzs for controllers now vs when I did the project, but they sell out quickly.
Power supplies: I bought 2 40A 12V Meanwell power supplies. I also bought some less expensive 5V power supplies to power the DigQuad controllers independently from the big beefy power supplies so I can keep the controllers always on and switch on tue big 12V power supplies with a relay when the lights are on (this is built into WLED, you just need to wire it up to a relay).
Aluminum Channel: I bought a bunch of v-shaped channels with a diffuser lens from Amazon. They came with brackets and screws.
Misc: I used a lot of 12 guage wire, waterproof heat-shrink butt connectors, hot glue, solder, waterproof adhesive strips, and heat-shrink tubing. Also bought 2 plastic enclosures for the controllers/power supplies and some connectors so I could unplug the controller box
The most complex parts of the project were all related to managing the power. I had to split up the install to limit the current for any given section of lights to a maximum of 10-12 amps. And I also had to hot glue power wires inside the channels along with the LED strips so I could inject power every 5 meters or so. Both of those together meant I had to run a lot wire around to each section.
The first thing I did was to install the aluminum channels. I put them on the top edge of my gutters and on the bottom edge of the soffits. Next I soldered together each individual run to the exact length, including the power injection wires. I did that at my workbench so I could test everything there before installing it. To splice together IP65 strips, you have to cut away the waterproof membrane, solder the pads together, fill the void of the removed membrane with hot glue, and then slide head shrink tubing over the splice. I would do a similar thing to solder on the power injection leads, and also solder on wire leads on both ends to connect it in the install. After that, I would install that length of LEDs in the channel, gluing the power injection wires along the sides of the channel with the LED strip. All wire connections I made with waterproof heat shrink butt connectors. Install the diffuser lens and that section is done. Connect the sections together and to the power supply/controller.
