WS2812B vs WS2811 LED Strip Lights: A Summary

The WS2812B and WS2811 LEDs are popular addressable options, but they have distinct characteristics that cater to different applications.

Key Differences

1. Integration of IC:

• WS2812B: The IC is built into each LED, allowing for easy control of individual LEDs. Each operates at 5V.

• WS2811: The IC is external to the LED, with the ability to work at multiple voltages (5V, 12V, or 24V). Depending on the voltage, it controls a group of LEDs:

5V: One IC per LED.

12V: One IC for three LEDs.

24V: One IC for six LEDs.

Voltage and Distance

WS2811 strips can run longer distances (up to 50m for 24V) with less voltage drop compared to the 5V WS2812B strips, making them more suitable for large projects or outdoor lighting.

Power Consumption

At 5V, the power consumption is similar, but the WS2811 LEDs at higher voltages consume more power due to the larger number of LEDs controlled by each IC.

Color Options

WS2811: Available in RGB, RGB+W (white), and RGB+CCT (tunable white), offering greater versatility in color selection.

Applications

Both types are used in various formats like SMD strips, pixel panels, and modules, and can be controlled using SPI controllers or Arduino boards.

Choosing Between WS2812B and WS2811

• Individual LED Control: Go for WS2812B if you need precise control over every single LED.
• Color Options: Choose WS2811 for a wider range of color options.
• Running Length: Opt for higher voltage WS2811 (12V or 24V) for longer runs without color inconsistencies.??
• Power Consumption: Consider power usage; 5V WS2812B might be more economical for small projects.

Conclusion

Choose WS2812B for projects requiring individual LED control at short distances. Opt for WS2811 when longer runs, higher voltage options, or varied color modes are needed.
