Quick Answer
For permanent outdoor facade and eave lighting in the US and Canada, the choice between UCS2904 RGBW and WS2811 comes down to white light quality and control precision. UCS2904 RGBW adds a dedicated white channel (6000K) for pure, clean architectural white alongside full-color effects — ideal for high-end residential and hospitality facades. WS2811 offers cost-effective full-color performance for projects where white is secondary. Both are IP67/IP68 rated, operate on 12V/24V/48V DC, and support the Surplife Wi-Fi controller for smartphone-based scheduling and scene control.
Introduction: Why Permanent Lighting Is Different
Permanent outdoor lighting — installed along eaves, soffits, and facade lines — has become one of the fastest-growing segments in the US and Canadian residential and light commercial markets. Unlike temporary holiday lighting, these systems are designed to stay in place year-round, which places unique demands on the products:
Requirement | Why It Matters |
|---|---|
Weatherproofing | Must survive rain, snow, ice, and UV exposure |
Consistency | Color and brightness must remain uniform across long runs |
Control | Homeowners expect app-based scheduling, color changes, and scene presets |
Installation | Must be achievable by professional installers without excessive labor |
The three products in this guide — 30mm UCS2904 RGBW, 30mm UCS2904IC with Lens, and 35mm WS2811 — are among the most popular solutions for these requirements. This guide breaks down their differences and provides a complete installation framework.
Product Comparison: Which Kit Fits Your Project?
Feature | 30mm UCS2904 RGBW | 30mm UCS2904IC with Lens | 35mm WS2811 |
|---|---|---|---|
LED Type | SMD 5050 RGBW (6000K) | SMD 5050 RGBW (6000K) | SMD 5054 RGB |
White Channel | Dedicated white (6000K) | Dedicated white (6000K) | Mixed RGB white |
Voltage | DC12V / 24V / 48V | DC12V / 24V / 48V | DC24V / 36V |
Power | 1.2W per light | 0.96W per light | 1.5W per light |
Size | 30mm diameter | 30mm diameter | 35×30mm |
Quantity per Chain | 3pcs | 20pcs | Customizable |
Pixel Pitch | 25cm (customizable) | 20cm | Customizable |
Protocol | UCS2904 SPI | UCS2904IC SPI | WS2811 |
Waterproof | IP67 | IP67 | IP68 |
Best For | High-end facade, hospitality | Long runs, eave lighting | Cost-effective residential |
Key takeaway: If the project requires pure, high-quality white light (for architectural highlights or daily illumination), choose UCS2904 RGBW. If the project is color-focused and budget-sensitive, WS2811 delivers reliable performance. The UCS2904IC Lens Type sits in the middle — offering RGBW quality with a higher pixel density per chain for longer runs.
Installation Guide: What You Need to Know
Based on our 30mm UCS2904 RGBW Permanent Lighting Installation Guide, here is the complete system architecture.
1. Light Spacing and Layout
Parameter | Specification |
|---|---|
Standard spacing | 5 lights per meter (20cm pitch) / 3.28ft |
End-of-run handling | When the eave end is less than 1 meter, a single light can be used to prevent cutting |
Customization | Pixel pitch can be customized to match specific architectural dimensions |
2. Cable and Connector System
The system uses a modular, waterproof connector architecture:
Connector | Function |
|---|---|
Female connector | Connects to the controller |
T power connector | Provides power input for light strings |
T data connector | Splits 1 signal into 2 outputs for branching runs |
Extension connector | Connects lights from one eave to an adjacent eave |
18AWG 2pin power bare wire | Required when connecting lights experiencing voltage drop to the power supply |
3. Signal Amplifier
A signal amplifier is required when:
The controller is located far from the lights
Two lights are spaced far apart
The lights exhibit flashing issues
4. Controller Setup (Surplife App)
The system is controlled via the Surplife Wi-Fi controller (DC12–48V input, max output 480W at 48V).

Step | Action |
|---|---|
1 | Register or log in to your Surplife account |
2 | Enable Bluetooth on your phone and power on the device |
3 | Open the app, tap "Add Device" or the "+" icon |
4 | Select your Wi-Fi network (2.4GHz only) and enter the password |
5 | Configure the IC type: Select Standard RGBW Mode |
6 | Color calibration: Follow the app prompts to calibrate colors |
7 | Set the number of lights |
Setting the number of lights:
Scenario | Setting |
|---|---|
Fewer than 300 lights | Input exact count (e.g., 225 lights → first field 225, second field 1) |
More than 300 lights | Split into segments (e.g., 500 lights → first field 250, second field 2) |
5. Mounting and Track Options
The installation guide includes aluminum track profiles for clean, professional mounting:

Track Type | Dimensions |
|---|---|
Track 1 | 40×25mm |
Track 2 | 58.4×20mm |
Track 3 | Custom |
Installation Steps:
Insert the aluminum groove into position
Secure it to the wall using screws
The groove is available in customizable colors and dimensions to match the facade
Which Kit Should You Choose?
