WS2815 vs SK6812: Key Differences
Here are the main differences between these two LED strips:
The primary distinction between the SK6812 and WS2815 is their color range. The SK6812 not only offers RGB color but also single-white, dual-color temperature, and RGBW compatibility. In contrast, the WS2815 provides RGB colors and separate whites, such as color temperatures of 3000K and 6000K.
The conventional SK6812 uses a single data line for signal transmission and lacks a resume function. However, recent models of RGBW/RGB LED strips with the SK6812 feature a resumable version. The WS2815 utilizes dual data lines for signal transmission, with a break-continuation function.

The SK6812 boasts higher brightness levels, capable of producing up to 100 lumens per watt (lm/W), compared to the WS2815’s 80 lm/W maximum output. This makes the SK6812 ideal for applications that require intense illumination.
Common Advantages of WS2815 and SK6812
Both the WS2815 and SK6812 share some key benefits:
High Color Accuracy and Consistency
As individually addressable LED strips, both the WS2815 and SK6812 deliver accurate color reproduction, often resulting in more vibrant and bold colors compared to non-individually addressable LED strips.
Minimal Voltage Drop
If you need long LED strip runs, consider the DC12V WS2815 or the 12V/24V SK6812 LED strip. Both options have low voltage drops and can maintain consistent brightness over extended distances.
