ART-LED DC12V WS2815 RGB LED Pixel Fairy Light String
Brand: ART-LED | Model: WS2815 | Certification: IP67 Waterproof
Product Overview
This product is a high-quality, individually addressable RGB LED pixel string light utilizing the advanced WS2815 IC chip. Operating on a safe 12V DC power supply, it features a compact pebble-like design with a 5cm pixel pitch. With an IP67 waterproof rating, it is designed for both indoor and outdoor permanent installation, offering vibrant dream-color effects for Christmas, holiday, and architectural decorative lighting. Each pixel (LED) can be controlled independently, allowing for dynamic animations and patterns.

Core Features & Benefits
-
Dual-Signal Backup (Breakpoint Continuation): Unlike traditional strips, the WS2815 has a backup data line (BI). If a single LED fails, the signal bypasses it, ensuring the rest of the string continues to function normally.
-
12V Operation: Higher voltage reduces current requirements, minimizing voltage drop over long distances. This means consistent color and brightness across the entire string without frequent power injection.
-
True Waterproof (IP67): Fully sealed in silicone, these lights can withstand temporary immersion in water, making them ideal for outdoor use in gardens, eaves, and landscapes.
-
Easy Installation & Customization: Features 4-pin connectors for easy daisy-chaining. The string can be cut to custom lengths at designated points (every 1 LED).
-
Wide Compatibility: Can be controlled by popular microcontrollers like Arduino and Raspberry Pi, as well as dedicated LED controllers (SPI, DMX decoders).
Installation & Usage Guide
Connection Diagram
The standard 4-pin wiring for WS2815 is as follows:
-
Red Wire: +12V DC (Power)
-
Black/White Wire: GND (Ground)
-
Green/Blue Wire: DI (Data Input)
-
Yellow Wire: BI (Backup Data Input)
Connect DI and BI to the same data output pin on your controller for redundancy.
Programming Example (Arduino)
Using the FastLED library, you can control the WS2815 similarly to the WS2812B:
#include <FastLED.h>
#define NUM_LEDS 40
#define DATA_PIN 6
CRGB leds[NUM_LEDS];
void setup() { FastLED.addLeds<WS2812B, DATA_PIN, GRB>(leds, NUM_LEDS); }
void loop() {
leds = CRGB::Red; // Set first LED to red
FastLED.show();
delay(1000);
}
Safety & Maintenance
-
Ensure the power supply is rated for 12V DC and has sufficient current capacity (calculate based on number of LEDs).
-
Do not power the strip while it is still rolled up to prevent overheating.
-
For outdoor installations, ensure all connections are properly sealed and waterproofed.
-
Clean the silicone surface with a soft, dry cloth to maintain light output.

Product Comparisons & Evaluations
WS2815 vs. WS2812B
The WS2815 is a significant upgrade from the popular WS2812B. The key differences are:
-
Voltage: WS2815 uses 12V, reducing voltage drop; WS2812B uses 5V.
-
Reliability: WS2815 has a backup data line for fault tolerance; WS2812B does not.
-
Current: WS2815 draws less current for the same number of LEDs, allowing for longer runs.
WS2815 vs. SK6812
While both are advanced, the SK6812 offers additional features:
-
Color Options: SK6812 comes in RGB, RGBW (with a dedicated white channel), and WWA (tunable white) variants, providing purer whites than the RGB-mixed white of WS2815.
-
Voltage Independence: SK6812 maintains more consistent color across varying voltage levels.
-
Use Case: WS2815 is favored for long, reliable outdoor runs; SK6812 is preferred for applications requiring high-quality white light or complex color mixing.
User Feedback Summary
Users praise this product for its brightness, color accuracy, and reliability in outdoor conditions. The 12V operation is frequently cited as a major advantage over 5V strips for large installations. Some users recommend adding a level shifter when connecting to 3.3V microcontrollers for optimal signal integrity.
