Review on 💡 WS2811 16.4ft 60LEDs/m Individually Addressable LED Strip - 5m 300LEDs Flexible Rope Light - Dream Color - White PCB Non-Waterproof DC12V: A Versatile Lighting Solution by Adam Stone

They work really well and are perfect for my project (general lighting effects). There is one WS2811 driver for every 3 physical LEDs in the chain and EVERY LED is an RBG. This means when you turn on a pixel, 3 LEDs light up. The length of the light bar for a "pixel" is about 3 inches. If you need full color and brightness control for long strings of LEDs, this strip is for you. If you need individual LED addressing, this is not for you. This product is perfect for 12v under cabinet lighting and you will have no problem with the blue tint of many 12v strips. The adhesive backing feels like real 3M (some of the other strips had trouble sticking, and it's clearly not double-sided 3M tape.
