Review on 🔥 BTF LIGHTING WS2812B Heatsink - 10mm x 3mm (WS2811 Compatible) by Kathleen Roy

They were perfect for my Arduino based game project. I used the FastLED library, but Neo-Pixel should work too. The individual panels (actually 9.5mm wide) are easy to tear off for more specific purposes, but I was able to stack them together to trim the panel to the required dimensions. Each LED chip can be very bright (draws up to 180mA) but is excellent for general indoor viewing at lower brightness settings. Have been using it for a few months with no problems.
