I think installing light strips is cool and convenient to create an atmosphere, but my mother thinks it is too complicated. Can anyone who has installed it tell me about the actual effect?

I installed a light strip around the ceiling of my house, but it stopped working within a year. I bought a new light strip, but recently I found that it seemed to have dimmed again. Now I don’t want to turn on the light every time. The light switch is basically useless. The trouble is that over time, dust tends to accumulate on it, and a thick layer not only affects the lighting effect, but also makes cleaning difficult.
