1.Individually Addressable: Using a programmable controller and you can led just you like. one led has own IC chip.one IC controll one led.The chip buil in led. 2.DIY: If you have a programmable controller , you can DIY your own effects 3.: Brightness can be adjusted freely.Do not stare at it for a long time, otherwise you will be when the led Brightness is the brightest. 4.Colorful: Red ,Green, Blue .Dream full color. 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 voltage: DC 5V : SMD 5050 RGB Beam Angle: 120 degree LED : 16*16 8*32 256 Pixels/8*8 64Pixels Power: 64LEDs 19.2W/ 256LEDs 75W Emitting Color: Full color (24-bit) Gray level: 64/256 Waterproof: IP30 non- waterproof Working temperature:-20Celsius~40Celsius IC: WS2812B (WS2811 IC built-in RGB chip) Precautionsp: 1.With 256 LEDs, you could use over 15A of current if you turn on all the LEDs on to white (which we really do not recommend because we ' the flex PCB can handle that much current). 2.Using voltage 5V DC. higher than 5V DC will destroy it. 3.Do not bend strip sharply. Flexible PCBs are not designed for repeated flexing 4.If you need better performance, you can use a K-1000C controller or another programmable controller. Colour:black+white Material:plastic Size:about 8x8cm Package Contents: 2 x LED Panel Only the above package content, other are not included. Note: Light and different displays may cause the color of the item in the a little different from the real thing. The measurement allowed error is +/- 1-3cm.
