WS2811 vs. WS2812B: How to Choose the Right LED Strip

LED strips are increasingly popular for providing intense illumination in various settings. They can enhance focus and creativity, making them versatile for many tasks. Addressable LED strips take lighting to a new level by offering various lighting effects, such as running chases, flowing fades, meteor trails, and more. With a control system, you can even customize your lighting effects. However, many types of addressable LED strips are available, making it challenging for people to differentiate between them.

The WS2811 and WS2812B LED strips are the most popular among digital programmable LED strip lights. Yet, distinguishing between them can be difficult for many. In this article, we'll compare the WS2811 and WS2812B to help you choose the right LED strip.

Overview of WS2811

WS2811 is specifically designed for LED driver circuits, offering three output channels. It includes an intelligent digital port data latch, a signal-reshaping amplification drive circuit, and a precision internal oscillator. With a programmable constant current output drive for 12V voltage, it also features a delay turn-on function in its three output channels to reduce power supply ripple.

The WS2811 is a basic addressable RGB LED strip, which means each LED's color can be controlled individually using a data signal. This signal can come from various sources, such as the digital pin on an Arduino board or a suitable SPI RGB LED controller.

It's important to note that this data signal is a pulse-width-modulated (PWM) signal. Pulse width modulation, or PWM, is a technique used to control the brightness of LEDs. "ws2811" refers to these LEDs originating from the ws2811 driver IC.

The ws2811 LEDs are designed to be powered by DC 12V, which is a noticeable voltage difference. Even when powered by DC 12V, the WS2811 RGB LED Controller can effectively perform its function.

Among its various applications, WS2811 is commonly used in flexible LED strip lights. These strips find wide use in facade lighting, wall lighting, backlighting, holiday (Christmas, etc.), stage design, staircase, display case, ceiling, and automotive lighting.

Overview of WS2812B

WS2812B is a smart LED light source that combines the control circuit and RGB chip into a 5050 component package. These LEDs have a built-in IC for communication through a single-wire interface. Additionally, they feature a smart digital port data latch and a signal reshaping circuit for drive amplification.

Inside the WS2812B intelligent control LED light source is a package of 5050 parts, including the control circuit and the RGB chip. It has a signal-reshaping amplifier drive circuit and an intelligently-processing digital port data latch. Also built into the device are a precision internal oscillator and a programmable constant current control element. These parts work together to keep the pixel point light's color height identical.

In the data transfer protocol, there is only one NZR communication channel. After the pixel has been turned on and reset, the controller will send the data to the DIN port. The first pixel will get the first 24-bit data and send it to the internal data latch. The internal signal of the amplification circuit shapes the other data, which is then sent through the DO port to the next cascade pixel.

After the signal has been sent, it is cut down to 24 bits for each pixel. Pixels use auto-reshaping transmit technology, which means that the number of pixels in a cascade is not limited by how fast the signal can be sent. LEDs run on a low voltage, which is good for the environment and saves a lot of power. They also have a high level of brightness, a wide angle of scattering, good uniformity, low power use, and a long lifespan. The integrated control chip in LEDs is changing to become a circuit with fewer parts, less space, and an easier way to assemble it.

WS2811 vs. WS2812B: Features

WS2811 vs. WS2812B: Power

The WS2811 LED chip operates at 12V, while the WS2812B chip operates at 5V. There can be a noticeable voltage drop along the strip when using an LED strip with many LEDs. This means the last few LEDs at the far end of the strip from the control board will receive a lower voltage.

For example, if you have a strip with 30 LEDs and experience a 2V voltage drop near the end, the last few LEDs will receive around 10V if you use a WS2811 chip. This is within the acceptable range for an LED designed for 12V operation. However, if you're using a WS2812B, which operates at 5V, the voltage drop will be 3V instead of the expected 5V. This represents a significant voltage decrease.

WS2811 vs. WS2812B: LEDs Controlled

The WS2811 cannot independently control a single LED; it controls groups of three LEDs. Since it cannot control less than three LEDs at a time, it cannot control any LEDs individually. In contrast, each WS2812B can control only one LED at a time. If you require individual control over single LEDs, the WS2812B is preferable to the WS2811 due to its finer control granularity.
