Review on BTF-LIGHTING WS2812B RGB 5050SMD Individual Addressable 16.4FT 60Pixels/m 300Pixels Flexible Black PCB Full Color LED Pixel Strip Dream Color IP30 Non-Waterproof for LED Screen, LED Wall - DC5V by Andrew Kamkoff

Honestly I can't say enough about BTF and their customer service. I've been ordering 2812B strips for a long time and I love the result. I had other customized strips that had an issue and BTF responded and replaced them immediately. Amazing customer service. I use 2812B strips for NeoPixel lightsaber blades. As a power source I use a KeepPower 18650 15A battery connected to an Arduino/Teensy 3.2 board. I've also tried it with the Spark Color 2, Nano Biscotte V4 and Prizm 5.1 controllers, worked with other high-capacity batteries. All were compatible with dozens of previous builds made by me and other members of my Saber build team. I have another SK6812 strip that works great so I bought this one. I make custom lightsabers (yes, Star Wars lightsabers). Me and a few dozen other people who are members of an online club assemble blades from polycarbonate tubes and LED strips are inserted into the tubes. Boards. We take two LED strips and place them back to back, connect them in parallel and then place resistors between the data panel and the adapter board. I've had the best results with 2812B strips. I hope all of this helps you decide which strips to buy. I have received many compliments on the brightness of these strips, thanks to BTF. Many of us in the group tried different strips. And some have proven they don't work. These strips were very successful for many of us.
