This specific film is COB Led technology, it is RGB and its width is 10mm, the same as classic SMD films. It is easily placed in aluminum profiles, it is quite flexible and because the LEDs are covered with phosphor coating, in case you need to remove and reattach it, there is no risk of easily breaking it and not illuminating from that point onwards. If placed behind a cover, no gap is visible between the LEDs. Unfortunately, it operates at 24V dc, so if you have 12V films, like in my case, you will have to bear the additional cost for new power supplies. I use them in some DIY floor lights, which I don't have directed towards the wall as hidden lighting, but towards the room, and many times they are the main lighting of the room. They are very bright, in white they can illuminate the space quite well. Their brightness is really great.

As negatives, I would mention their high price (36.5 euros purchase price), without coming with a controller. I would also prefer the saturation of the colors (Red, Green, Blue) to be more intense, and in white (cool-warm) it seems to have a slight bluish tint. Of course, RGB films do not have separate LEDs for white light, but the previous RGB film I had, from the Sonoff company, had better color rendering for white. Despite their high price, I am absolutely satisfied with the purchase, the only question is their durability over time. If someone is thinking of installing LED films in their home, I would recommend going straight to COB films.
