WS2811 strip light is the external IC addressable pixel tape that launched firstly in the market, earlier than WS2812B, WS2813 and WS2815. It only has on data line but is stable ,  only ca be made to DC5v , technology is mature. Clients all know this and need a lot.

 

WS2811 VS UCS1903

WS2811 is clone of UCS1903 which was launched by Linesun -ic company founder is from Taiwan.

UCS1903 is the most stable.

 

WS2818 LED strip is the latest pixel strip light, with both DC12v and DC24v option. Break continue function , dual data lines. With time flowing , this IC will be more stable I think. Currently (2019.7.2), the WS2818 IC is not as stable WS2811 / UCS1903 pixel LED strip.

 

We make a table for clear comparison among IC WS2811, US1903 and WS2818 strip light.

The main difference

1. WS2818 can be made to both DC12v and DC24v, currently WS2811 / UCS1903 only made to DC12v pixel strip light

2. WS2811 / UCS1903 IC only has one data line, WS2811 programmable light has double data lines.
