Quick Answer
The XXA-303RGBW-UCS7604 is a 30mm permanent pixel light engineered for demanding outdoor architectural installations. It features 3 × SMD5054 RGBW LEDs with dedicated warm/cool white channels, driven by the UCS7604 IC with true 16-bit (65,536-level) grayscale. Operating at DC24V, 0.96W per unit, with an IP67 rating and 4-pin M12 waterproof connectors, it delivers unprecedented color depth and reliability for large-scale facades and landscape projects.
Introduction: Why 16-Bit Grayscale Changes Outdoor Lighting
In standard outdoor pixel lighting, 8-bit grayscale (256 levels) is the norm. It works for basic color changes, but when you need smooth, cinematic fades or deep, rich color transitions, 8-bit falls short — you see "stepping" or banding.
The new XXA-303RGBW-UCS7604 solves this with the UCS7604 driver IC. By pushing grayscale to 16-bit (65,536 levels), it delivers true, professional-grade color reproduction outdoors.
But it doesn't stop at color depth. This module is built for the realities of permanent outdoor installations: IP67 waterproofing, M12 connectors, and intelligent dual-channel data redundancy to keep the show running even if a single pixel fails.
1. The Core Technology: UCS7604 Driver IC
The heart of this module is the UCS7604 — an intelligent, 4-channel LED driver designed specifically for high-end outdoor displays.
Feature | Specification |
|---|---|
Grayscale | 16-bit (65,536 levels) — true professional color depth |
Channels | 4 (R, G, B, W) with independent current adjustment |
Refresh Rate | 16kHz port refresh frequency — flicker-free for broadcast |
Data Transmission | 800K/S or 1.6M/S (optional) |
Constant Current | 0–60mA per channel, adjustable via external resistor |
Anti-Interference | Patented S-AI technology |
Fault Tolerance | Dual-channel redundant data transfer (99%+ success rate) |
Why 16-Bit Grayscale Matters
Grayscale | Levels | Visual Result |
|---|---|---|
8-bit | 256 | Visible banding in fades and gradients |
16-bit | 65,536 | Smooth, seamless color transitions |
For architectural facades, landscape lighting, and broadcast-critical installations, 16-bit is the difference between "LEDs" and "professional lighting."
2. Built for the Outdoors: IP67 & M12 Connectors
Permanent outdoor installations demand hardware that survives.
Feature | Specification | Why It Matters |
|---|---|---|
IP Rating | IP67 | Dust-tight, immersion-resistant for 30 min at 1m |
Lens | Clear lens (IP66 rated) | Optical clarity without compromising protection |
Connector | 4-pin M12 waterproof M/F | Secure, industry-standard connections |
Housing | Sealed, outdoor-rated | Withstands rain, snow, and UV exposure |
M12 Connectors: The Industry Standard
Unlike standard JST connectors, M12 provides:
Threaded locking mechanism
IP67 protection when mated
Reliable signal and power transmission
Easy daisy-chaining
3. Flexible Configuration: 10cm Spacing, 20pcs/strand
The XXA-303RGBW-UCS7604 is delivered in a standard configuration that suits most outdoor projects:

Landscape installations | 30mm size, clear lens, IP67 protection |
FAQ: 30mm RGBW Permanent Pixel Light
Q1: What is 16-bit grayscale and why does it matter for outdoor lighting?
16-bit grayscale means the LED can display 65,536 levels of brightness per color channel, compared to 256 levels in standard 8-bit systems. For outdoor architectural lighting, this eliminates visible banding and stepping in fades, gradients, and color transitions — especially important for large facades viewed from a distance.
Q2: What does the UCS7604 IC provide?
The UCS7604 is a 4-channel LED driver with 16-bit grayscale, 16kHz refresh rate, and patented dual-channel redundant data transfer. It ensures smooth color transitions, flicker-free performance, and reliability even if a single pixel or data line fails.
Q3: What is the difference between IP67 and IP66 on this module?
The module itself is rated IP67 (dust-tight, immersion-resistant). The clear lens is rated IP66 (dust-tight, powerful water jet-resistant). Combined, the module is suitable for exposed outdoor installations, including areas with rain, snow, and temporary water contact.
Q4: Can I use this module for a large-scale facade project?
Yes. The XXA-303RGBW-UCS7604 is designed for permanent outdoor installations. With M12 waterproof connectors, IP67 rating, and dual-channel data redundancy, it is suitable for large-scale architectural facades, bridges, and landscape projects. Custom spacing and strand lengths are available upon request.
Q5: What is the power consumption of this module?
Each module consumes 0.96W at DC24V. For a strand of 20 modules, total power is approximately 19.2W. The UCS7604 driver allows independent current adjustment per channel via software, giving you precise control over brightness and power consumption.
