To better understand the differences between these two LED strips,  let’s examine their key features.

SK6812 LED Strips

The SK6812 is a variant of the WS2812B and shares many similarities with its predecessor. However, it offers improved performance, particularly in terms of voltage drop sensitivity. The SK6812 maintains consistent color and brightness across a wide voltage range, making it a reliable choice for various applications.

WS2815 vs SK6812: Key Differences

Here are the main differences between these two LED strips:

LED Color

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.

Break Continuation

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.
