WS2811 is the old version with external IC, it is often made to DC12v addressable strip light, has only one signal too but it is mature for many years. WS2811 LED strip is an economical addressable LED strip controlled by external IC WS2811. Each IC controls 3 LEDs, so every 3 LEDs can be cut into a pixel. Each pixel is individually addressable, which makes it very flexible in many applications.
WS2812B LED strips are DC5v individually addressable strips with IC embedded into 5050 LEDs. The built-in IC is invisible from the outside, which makes the strip stronger and more flexible, and can be applied to different types of surfaces. Each LED is cuttable as an individually addressable pixel. WS2812B LED strip has only one data signal when one pixel dies, the signal cannot pass through.
WS2813 intelligently controls the LED light source, integrating the control circuit and RGB chip in a 5050 element package. WS2813 is another DC5v built-in IC strip light. It includes an intelligent digital port data latch and signal to shape amplifier drive circuit. The main feature of the WS2813 Strip is that a broken LED will not affect other LEDs unless two consecutive LEDs are broken.
We will show the difference between WS2811, WS2812B, and WS2813 features in the form of a table, pls see below:
Table 1. Features Differences between WS2811 vs WS2812B vs WS2813 from SuntechLED
|IC||External IC||Built-in IC||Built-in IC|
|LED per meter||60 leds/m||60 leds/m||60 leds/m|
|Power consumption||14.4w/m ||18w/m||18w/m|
|Control Mode ||3LEDs group control||Individual control||Individual control|
|Wires||Positive + Negative + Single Data line||Positive + Negative + Single Data line||Positive + Negative + Single Data line|
Through the above table, we know the difference between WS2811 vs WS2812B vs WS2813, Next, let's take a look at the difference between LED voltage (5v vs 12v).
Table 2. Power Differences between WS2811 vs WS2812B vs WS2813 from SuntechLED
|voltage drop (30leds/m for example)||Low ||High||High|
The WS2811 LED chip runs on 12V. On the other hand, the WS2812B chip and WS2813 only need 5V. If you use an LED strip with a lot of LEDs, you'll see a lot of voltage drop across the strip, which means the last few LEDs on the far end of the strip will have lower voltages.
More addressable strip comparisons:
WS2811 is three LEDs controlled by one IC, it doesn't control a single LED. This means you can't control them with less than three LEDs.
On the other hand, WS2812B or WS2813 LEDs are individually controlled by IC, 1pcs IC controls 1pcs LED. If you need a control granularity of 1 LED, the WS2812B or WS2813 should be used instead of the WS2811.

IC Quantity(60leds/m for example)
|20 pcs||60 pcs||60 pcs|
The WS2811 works at 12V, so it consumes more power. The WS8212B and WS2813 can operate with significantly reduced power consumption because they operate at 5V.
Next, let's take a look at the pros and cons of WS2811, WS2812B, and WS2813, which will help us find more suitable products.
