LED Power Diode COB 12W White SMD

4 RGB LED panel with digital control to be connected in cascade to complete the reception and decoding of the data.
The light emitted is very powerful and millions of colors can be generated thanks to the RGB device. 40 LED RGB Digital Panel Adafruit Neopixel with Connectors 5050 Matrix features:
- 40 individually addressable RGB LEDs (NeoPixels based on SK6812 or WS2812B) arranged in a 5 × 8 matrix
- 24-bit color control (8-bit PWM per channel); 16.8 million colors per pixel
- The digital control interface of a single cable requires only one Arduino pin (the default pin can be customized)
- Operating voltage range: 4 V to 6 V (connected to the 5 V Arduino rail by default)

Mount LED Diode on a good heatsink, a metal plate, add some fan, this is necessary because you have to " remove "the heat from the surface of the plate so that the LEDs last longer to place a little bit of thermal silicone in each of the centers of placement of the diodes.
The thermal paste increases the thermal transfer between the diode and the metal plate used as a circuit.
Important to keep in mind the diodes generate a lot of light intensity and very concentrated.
Avoid looking directly at them once they are turned on and wear protective glasses when working with them.
Characteristic:
- Chip 28x47mil
- Voltage: 3.0-3.2V
- Current: 300mA - Luminous flux: 120-130LM
- Beam angle: 130 degrees

This chain has DC5V LEDs that have built-in logic, so it is possible to vary the colour of each LED individually.

WS2811 includes a built-in integrated inside each LED, which allows access to each pixel individually. Black background

Easy programming with Arduino, ESP32, ESP8266, etc. 

RGB LED SMD5050 WS2812B with white packaging, waterproof level IP20.
They are smart that are used to create places with decorative lighting, lighting the information screens located inside and outside facilities.
They must be integrated to be operated with the help of any type of smart strip controllers, which can be: autonomous (offline), subordinate (online), light scattering ( to create musical lights) and programmable (control). LED RGB 5050 WS2812B White features:
- Power supply: +3.7 - +5.3 VDC
- Logic input voltage: VDD-0.5～VDD + 0.5
- Operating temperature: -25 ° C - + 85 ° C
- Storage temperature: -40 ° C - + 105 ° C - 4 pins: 1- VDD: LED power supply

COB LEDs are built as a matrix of LEDs, that is, a concentration of LEDs in a silicone coated tablet.
The advantages of LED COB:
- A luminous performance of up to 120 lumens / watt (twice as much as LED SMD)
- The light intensity is greater without needing to concentrate so much the beam of light
- Greater durability
- Angle of opening up to 160ºC
- Multidirectional light
