INDIVIDUALLY ADDRESSABLE. You can control each LED individually! Yes, that's right; this is the digitally-addressable type of LED strip. You can set the color of each LED's red, green and blue component with 8-bit PWM precision (so 24-bit color per pixel). WS2812B Led strips are work great with Arduino, FastLED library, Adafruit NeoPixel Library and Raspberry Pi.
FULL COLORFUL & HIGHEST DENSITY. 256 brightness display and full 24-bit color display. You can control each LED Pixel individually and set it to any color or animation you want. There are 144 LEDs/m and WS2811 IC is built-in 5050SMD, the highest density digital pixel led strip so far.
CUTTABLE&CONNECTABLE. WS2812B strip is made of flexible PCB material, can cut it pretty easily with wire cutters, and of course, each can be connected end to end by 3-pin JST connector easily, so you can DIY for any length you want.
HOW TO GET IT WORK: First, you will need an output is 5V power supply and controller(Both not included). Second, Connect Power and Ground from Power Supply. Third, Connect Ground and Control (data) wire to whatever you are driving the string with - Arduino, ESP8266 or any controller.
SAFETY & EASY INSTALLATION. Work under DC6V, low voltage for human safety, low power consumption, energy-saving, super-bright but running with low temperature. It comes with self-adhesive 3M tape on its back, so you can fix it on any dry and flat surface without any screws and clips.

Description

WIDELY USED.Widely used on LOGO screen, advertising board, applied to hotel, bars, wedding, party lighting and Mother's Day, Halloween, Christmas holiday lighting decor. Really good for replace the traditional neon signs.
EASY TO PROGRAM.Works great with Arduino, FastLED library, Raspberry Pi & FadeCandy etc. It can also be controlled by SP105E and other pre-programmed WS2811 controllers.

Features:
The WS2812B strip is low power consumption, Super-bright but running with low temperature. And every 5050 RGB SMD built-in one WS2811IC Chip, realize individually Addressable,
means every one led lighting effect can be controlled, each LED is programmable, with 8 bits of red, green, and blue data shifted in for 24 bit color, Strips take data in green, red, blue order.
Match use controller can appear colorful curtain-up/ flow water/raindrop/jump flash and so on hundreds of lighting effect, you can also edit animation effect by Coreldraw/Flash/LedEdit software.

Package:
1x 3.3ft WS2812B LED strip

Kindly note :
1) It comes without power supply and controller. You'll need a controller such as an Arduino to use them.
2) The work voltage of the LED string must be under 6V DC. Otherwise, it will be burnt out.
3) If you want to hook up more than one string, an external power supply is very necessary.
