Wall Wash-D113 LED Downlight Square 15-25W Manufacturer

What is the Wall Wash-D113 LED Downlight Square and where is it specified?

At XHLWX (led-project-light.com), a Custom Indoor LED Lighting Manufacturer based in China, we present the Wall Wash-D113 series—an architectural-grade square downlight engineered for superior vertical surface illumination. This luminaire moves beyond simple accent lighting, utilizing a precision-formed asymmetric lens to cast a smooth, even sheet of light down walls. This technique eliminates the distracting scalloping effect common with conventional downlights, creating a visually clean aesthetic that makes spaces feel brighter, larger, and more sophisticated. The D113 is designed for architects, lighting designers, and contractors in the European, US, and Middle Eastern markets who require a reliable and high-performance solution for highlighting feature walls, artwork, and vertical textures. Available in 15W (XH-DL-OR-15W-4S), 20W, and 25W power configurations, it provides the flexibility and output needed for a wide range of commercial and institutional ceiling heights.

Photometric and electrical specification

The Wall Wash-D113 is built to meet demanding project specifications. We provide comprehensive photometric data and support for lighting design software to ensure predictable, high-quality results. All configurations are subject to rigorous quality control under our ISO9001:2015 certified process.

Which spaces is it designed for?

The primary function of the Wall Wash-D113 is to enhance vertical surfaces, which play a crucial role in spatial perception and architectural definition. By focusing light on walls, you can define boundaries, guide circulation, and create dramatic focal points within a space.

How can I achieve uniform brightness on a gallery or retail feature wall?

To illuminate a feature wall in a gallery or retail environment effectively, the D113's asymmetric optic is indispensable. For a standard 3-meter (10-foot) ceiling, placing the fixtures approximately 0.8 to 1.0 meters from the wall and spacing them 1.0 to 1.2 meters apart creates a seamless wash. This setup can achieve vertical illuminance levels of 300-500 lux, making merchandise pop and artwork details vivid. Specifying a CRI95+ or CRI98+ chip ensures that colors are rendered with the highest fidelity, crucial for accurately displaying textiles, cosmetics, and art.

What is the best way to light a hotel lobby or corporate corridor?

In hospitality and corporate environments, the D113 creates a feeling of openness and luxury. By washing the main walls of a corridor or lobby, you draw the eye upward and outward, making the space feel wider and more inviting. Using warm CCTs like 2700K or 3000K enhances this welcoming ambiance. The precision optics ensure a low glare rating (UGR<19), maintaining visual comfort for guests and staff even as the walls are brightly lit. The clean, trimless appearance of the square housing integrates flawlessly into modern architectural ceilings.

Can this fixture be integrated into a smart office or school lighting system?

The D113 is engineered for full compatibility with modern building management systems. When specified with a DALI-2 driver, each fixture becomes an individually addressable node in a smart lighting network. This allows for sophisticated control strategies, such as daylight harvesting in perimeter offices or scene-setting in boardrooms and auditoriums. For human-centric lighting applications in schools or offices, the fixture can be configured with Tunable White (TW) or Dim-to-Warm (DTW) LED modules, allowing the color temperature to be adjusted throughout the day to support circadian rhythms.

Installation, control and compliance (DALI-2 / Casambi / 0-10V, CE / RoHS / ErP)

Installation of the D113 is streamlined for professional contractors. The luminaire requires a square 95x95mm cutout and is secured by durable, spring-loaded clips. The external driver is connected via a simple plug-and-play connector, allowing it to be placed remotely for easy access and optimal thermal performance.

We offer a full suite of control options to meet international standards:

• DALI / DALI-2: For addressable, digital control in commercial systems, including DT8 support for Tunable White and RGBW control.
• 0-10V / 1-10V: For reliable analog dimming.
• TRIAC (Phase-cut): For residential and small-scale commercial projects using leading/trailing edge dimmers.
• Wireless: Options include Bluetooth Low Energy (BLE) for Casambi networks and ZigBee for broader IoT integration.

All versions are fully compliant with European Union directives, bearing the CE mark (covering LVD and EMC standards), RoHS certification for hazardous substances, and ErP compliance for energy efficiency. We provide full documentation and Declarations of Conformity for project submittals. To facilitate your design process, we offer complete IES and LDT photometric files for use in DIALux, AGi32, and other professional lighting simulation software.

Frequently Asked Questions

Q: What is the recommended spacing for a continuous wall wash effect?

A: For a uniform effect on a 3-meter high wall, a common practice is to space the D113 fixtures approximately 1.0 to 1.2 meters apart on-center. They should be set back from the wall at a similar distance, between 0.8 to 1.0 meters, to achieve a smooth light gradient without hotspots or dark zones.

Q: Are specific TM-30 reports available for museum projects?

A: Yes, absolutely. For museum and gallery specifications requiring precise color rendition data, we can provide full TM-30-20 reports for our high-CRI options (CRI95+ and CRI98+). These reports detail the Fidelity Index (Rf), which is typically >92, and the Gamut Index (Rg) to ensure accurate representation of artwork. These are available with your IES file request.

Q: Can I get this downlight with an IP44 rating for a bathroom?

A: The standard Wall Wash-D113 model is rated at IP20, suitable for dry indoor locations only. While a custom IP44 version is not standard for this housing, we offer alternative wall wash solutions in our portfolio with IP44 or higher ratings suitable for bathroom zones 2 and 3. Please contact our technical team for recommendations.

Q: What is the warranty, and what does it cover?

A: The Wall Wash-D113 series comes with a comprehensive 5-year warranty. This covers defects in materials and workmanship, including the LED module and the external driver. We guarantee a lumen maintenance of L80B10 at 50,000 hours, ensuring long-term performance and reliability for your project. Complete warranty terms are available upon request.
