IP67 Outdoor 40mm 2W RGBW LED Point Light Source Featuring 48V DMX Control for Hotel Facade Eave Decoration

IP67 40mm RGBW 4-in-1 LED Point Light Source — Professional Architectural Pixel Lighting

The ELP-P40RGBW-DMX48 is a purpose-built architectural-grade LED point light source designed for permanent outdoor installations on hotel facades, building contours, eaves, and landmark structures. By combining RGB full-color capability with a dedicated high-CRI white LED in a single SMD5050 package, it solves the industry problem of weak, tinted whites that plague standard RGB-only pixel lights.

Technical Specifications

Why RGBW Over Standard RGB?

Conventional RGB point lights mix red, green, and blue to approximate white — resulting in a bluish or greenish cast that looks unprofessional on high-end architectural projects. The ELP-P40RGBW-DMX48 integrates a dedicated 4th white channel, delivering true warm white (3000K), natural white (4000K), or cool white (6000K) illumination. During the day or for corporate branding scenarios where pure white is required, the difference is unmistakable.

Key Features

• True RGBW 4-in-1 LED Engine: SMD5050 package with independent R, G, B, and W channels. Achieves 16.7 million colors plus pure white — ideal for both dynamic color shows during holidays and clean architectural white for daily hotel operations.
• 48V Safe Low-Voltage Architecture: Operating at 48V DC rather than 12V/24V enables significantly longer cable runs with minimal voltage drop. One power supply can drive more pixels, reducing installation complexity and cost on large building facades exceeding 100 meters.
• DMX512 + SPI Dual Protocol: Native DMX512 support integrates directly with professional lighting consoles (Madrix, MAD Mapper, Resolume). Also compatible with SPI protocols (WS2811, UCS2904) for simpler controller setups. Each pixel individually addressable for video-grade effects.
• IP67 Fully Sealed Construction: Die-cast aluminum base with UV-stabilized PC lens, sealed with automotive-grade silicone gasket. Survives heavy rain, snow accumulation, and coastal salt spray. Tested to IP67 standards — protected against dust ingress and temporary immersion.
• 40mm Form Factor — The Sweet Spot: Large enough for visibility at 50+ meters on building facades, yet compact enough for dense pixel grids (down to 50mm pitch). Ideal pixel size for architectural contour tracing where the light source should be visible but not obtrusive.
• UV-Stabilized Optics: The PC lens incorporates UV inhibitors that prevent yellowing over years of sun exposure — a common failure point on cheaper point lights that turn cloudy within 12-18 months.
• Daisy-Chain Wiring: 3-pin waterproof connectors on each pixel enable plug-and-play cascading. Each connector junction is itself IP67-rated, eliminating the need for field-sealing or heat-shrink tubing during installation.

Applications

Hotel Facade & Building Contour Lighting

Trace the architectural silhouette of hotels, office towers, and commercial buildings with individually controllable pixels. During business hours, run warm white static mode for elegant corporate presentation. After dark, switch to dynamic RGB color sequences synchronized to holidays, events, or brand colors.

Eave & Roof Edge Decoration

The 40mm diameter and 48V power system make this point light ideal for eave perimeter installations. The compact size integrates cleanly with architectural lines without detracting from the building's daytime appearance.

Christmas & Holiday Lighting

Program festive red-green-gold-white sequences across entire building faces. The RGBW chip's dedicated white channel produces brilliant, true white for snowflake effects and winter themes that standard RGB pixels simply cannot match.

Bridge & Landscape Accent

Weather the harshest outdoor conditions with IP67 protection and -30°C to +60°C operating range. Suitable for bridges, park landscapes, waterfront promenades, and public art installations.
