I am in the process of getting the necessary hardware for my setup. I saw LED neon tubes on the BTF-Light on aliexpress and wanted to know in advance whether they make sense at all. I was planning to stick the LED strips on a frame that is slightly raised from the TV (i.e. not directly on the back). My 55" LGTV hangs about 15 cm from the wall. I would like to use SK6812-RGBNW with 60LED/m as a 5V version. As a controller, I got my own WLED-Board.
I am open to suggestions and ideas for improvement.
Edit: I see there is only a SK6812 12V on a shop called zedfy.
Edit2: Found this 12V Sk6812 with Cold-White (6000-6500k)
