SK6813 LED Strip works for engineering lighting projects in complex environments, serving in the field of dynamic LED control and high-precision display. As a built-in IC, SK6813 can achieve individual pixel control. With dual-signal transmission (DAT&BAK), SK6813 LED strip light has stronger anti-interference ability and long-distance data transmission capability. SK6813, GS8208 and WS2815 are the most popular in engineering lighting.

Adopting fine PWM modulation technology, SK6813 supports 256-level grayscale adjustment to ensure smoother color transition. It supports RGB and RGBW modes and has a built-in constant current driver circuit that automatically adjusts the current to provide more precise brightness control. SK6813 IC operates at a low voltage of 5V, but it can also be applied in a 12V LED light strip with an external step-down circuit to convert 12V to 5V. Nowadays, SK6813 LED strip is widely used in advertising displays, stage lighting, architectural lighting, and other fields, providing flexible control options and excellent display effects.

SK6813 VS SK6812

1.SK6813 has two signal lines, equipped with breakpoint-resume function. SK6812 usually adopts single signal transmission.

2.SK6813 has a higher refresh rate, perfect for complex dynamic lighting display. The refresh rate of SK6812 is lower, suitable for simple dynamic display effect.

3.SK6813 is usually seen in 5V and 12V light strip. While the SK6812 is typically used for 5V, 12V and 24V strips.

What is WS2813 LED strip?

WS2813 is the upgraded version of WS2812B. Like WS2812B, the WS2813 is packaged in an SMD5050 RGB/RGBW LED and is driven by 5VDC. Single LEDs can be cut and each LED is individually addressable. We offer 30, 60, 96, and 144 LED densities for WS2813 LED strip lights.

WS2813 VS WS2812B

In terms of communication, WS2813 is upgraded to dual signal transmission, and the transmission continues at the signal breakpoint. When a single pixel LED is damaged, it does not affect the overall color display, unless two consecutive LEDs are damaged. More reliable use and less subsequent maintenance trouble.

WS2813 has a better color display and higher transmission rate (2000Hz) than WS2812B, without flicker in the camera shooting.

WS2813 has a reset time of 250μs (WS2812B - 280μs), allowing LEDs to work better at lower frequencies and in cheaper microcontrollers.

WS2813 LED strip can work simultaneously with WS2812B LED strip (note the pins) and is compatible with Arduino, Raspberry PI development boards, and dream color addressable LED controllers to achieve beautiful colors.

WS2818 is an upgraded version of WS2811, featuring redundant signaling that significantly enhances the stability of IC-controlled LED strip lighting systems. WS2818 LED strip uses 12V DC as its operating voltage, and its 8-pin IC is externalized to 5050 RGB LEDs, each WS2818 IC is capable of controlling three LEDs simultaneously. A data transfer rate of 800Kpbs and a refresh frequency of up to 2KHz/s enable WS2818 12 volt addressable RGB LED strip to respond smoothly and quickly to the controller's SPI signals for complex, dynamic pattern synchronized displays.

Compared to 5V WS2813 and WS2812B, the WS2818 raises the voltage to 12 volts and is able to support strip runs up to 5 meters with the same specifications. WS2818 LED 12V light strips, while not carrying over the individually addressable feature of 12V WS2815, are more cost-effective than WS2815 RGB in most animated effects lighting scenarios. Browse our products for your project now.

TM1914 and TM1934 are 4 pin addressable led strip IC chips, with redundant data signals, compatible with 12 and 24 volt operation, capable of data rates up to 800kbps and PWM frequencies up to 666Hz. As a fixed IC chip outside the LED package, a single TM1914 or TM1934 simultaneously controls all LEDs in a single cut-out zone, with RGB/CCT/White color programming via an SPI-compatible controller. 

As non-individually addressable LED strips, TM1914 and TM1934 have their color presentation directly influenced by the number of ICs on the flexible PCB strip. A higher number of ICs significantly enhances the delicacy and richness of the color display, resulting in superior lighting effects for interior and exterior projects.

The signal integrity of the TM1914 and TM1934 4 wire led strips is maintained over longer distances when compared to the 12-volt DC-driven WS2815, SK6813, WS2818, GS8208 and 5-volt low-voltage-driven WS2813 led tape strip lighting. Our 24V RGB TM1934 4 prong led strip can expand up to 20 meters 65.6 feet away with a single-ended signal input. Pick up your order now!
