Key Features

1. RGBW 4-in-1 Color – Pure White & Vivid Colors

The combination of 12 SMD2835 LEDs and 5 RGB LEDs delivers:

  • RGBW color mixing — full-color effects with a dedicated white channel

  • Pure, clean white light — no color mixing artifacts

  • Vibrant RGB colors — for dynamic pixel displays

2. Dual Control Protocol Options – SPI (TM1824) or DMX

Protocol

IC Chip

Advantages

SPI (TM1824)

TM1824

Fast data transmission, cost-effective, ideal for pixel-mapping and dynamic animations

DMX (UCS512CN)

UCS512CN

Industry-standard protocol, long-distance reliability, professional console integration

3. Single-Point Pixel Control

Each unit is individually addressable, enabling:

  • Pixel-level control — precise color and brightness per point

  • Complex animations — chasing, flowing, and gradient effects

  • High-resolution displays — ideal for video mapping

4. 75mm Diameter with 75mm Mounting Hole

The 75mm size is ideal for:

  • Large-scale facade lighting

  • High-visibility pixel displays

  • Architectural accents — where larger light points are required

5. Dual Beam Angle Options

Beam Angle

Best For

36°

Narrow spotlighting, focused accent lighting

120°

Wide flood lighting, general illumination

6. 4-Pin Connectors – Easy Daisy-Chaining

The 4-pin male/female connectors provide:

  • Simple daisy-chaining — extended runs with minimal wiring

  • Secure connections — reliable signal and power transmission

7. 256-Level Grayscale – Smooth Dimming

With 256 levels per channel, this pixel light delivers:

  • Ultra-smooth dimming — no visible step changes

  • Accurate color mixing — professional-grade transitions

  • Flicker-free performance — suitable for video recording

8. Flexible PCB Color – Black or White

PCB Color

Best For

Black

Blends into dark backgrounds

White

Reflects light for enhanced brightness
