Wall Wash-D75 LED Downlight Round Trimless 10-12W

What is the Wall Wash-D75 LED Downlight 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-D75 LED Downlight, a sophisticated architectural luminaire designed for creating flawless vertical illumination. This 10-12W fixture, with its round trimless design (product code XH-DL-OR-10W-3RT / XH-DL-OR-12W-3RT), is engineered to be plastered directly into the ceiling, resulting in a perfectly clean, seamless finish with no visible bezel. The core feature is its specialized asymmetrical optic, which directs light sideways to wash walls evenly from top to bottom, eliminating scalloping and creating a sense of spaciousness. It is the preferred choice for architects and lighting designers in the EU and US specifying lighting for high-end retail, contemporary office spaces, hotel lobbies, and art galleries where both aesthetic minimalism and precise lighting performance are paramount. The fixture's Ø75mm cutout and 94mm height make it a compact yet powerful solution for modern interiors.

Which spaces is it designed for?

The Wall Wash-D75 is specifically engineered for applications where vertical surfaces are a key part of the design narrative. Its ability to deliver smooth, uniform light makes it a powerful tool for specifiers and contractors working on sophisticated commercial projects.

How does the trimless installation create a minimalist aesthetic?

The trimless, or 'plaster-in', design is fundamental to its architectural appeal. The fixture is installed before the final skim coat of plaster, with a perforated flange that gets covered and feathered into the ceiling surface. The result is a clean, zero-sightline aperture from which light emerges, as if from the architecture itself. This 'disappearing' fixture is ideal for luxury retail, modern homes, and corporate boardrooms where the focus should be on the illuminated space, not the hardware in the ceiling. It supports a design language of minimalism and integration.

What makes the asymmetrical optic ideal for uniform wall washing?

Unlike a standard downlight that produces a symmetrical cone of light, the D75's wall wash optic incorporates a specialized reflector and lens combination. This optical system directs the peak candlepower at an angle (typically 20-30 degrees from nadir) towards a specific surface. When placed at a calculated setback distance from the wall (e.g., 60-80cm), the light distribution spreads vertically and horizontally, creating a smooth gradient of light from ceiling to floor. This technique can achieve an average of 150-300 lux on the vertical surface, making it perfect for accentuating artwork, highlighting brand walls, or creating a brighter, more open feel in corridors.

How does high CRI and adjustable color enhance merchandise or artwork?

For applications in museums, galleries, or high-end retail, color accuracy is non-negotiable. The D75 is available with CRI values up to an exceptional CRI98+, ensuring that colors are rendered with almost perfect fidelity. Combined with high TM-30 metrics (e.g., Rf 95, Rg 101), it reveals the true saturation and hue of textiles, artworks, and luxury goods. We also offer options for Tunable White (TW) and Dim-to-Warm (DTW), allowing dynamic control over the color temperature from a warm 1800K to a cool 4000K. This flexibility enables operators to adjust the ambiance to match the time of day or the specific merchandise on display.

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

The Wall Wash-D75 is supplied with a remote driver, which simplifies installation into shallow ceiling voids and improves thermal management for the LED. It is compatible with a wide array of control protocols used across Europe and the US. We can supply drivers for DALI-2 (offering individual addressability and feedback), standard 0-10V or 1-10V analogue dimming, and wireless solutions like Casambi (Bluetooth Mesh) or ZigBee. Every configuration is designed for seamless integration into modern building management systems (BMS). The luminaire and its standard driver configurations are fully certified with CE and RoHS, and meet EU Ecodesign requirements (ErP), guaranteeing compliance for project handover.

Customisation, MOQ and lead time

As a manufacturer, we offer extensive customization. Beyond the standard Matt White and Matt Black finishes, we can provide custom RAL color powder coating to match any interior design palette. Minimum Order Quantities (MOQ) for standard configurations begin at 100 units. For custom finishes or non-standard CCT/CRI combinations, a higher MOQ may apply. Our typical production lead time for orders up to 1,000 units is approximately 20-28 working days from drawing approval to dispatch from our facility in China. We work closely with contractors and distributors to meet project timelines.

Frequently Asked Questions

Q: What is the benefit of the ADC12 die-cast aluminum housing?

A: ADC12 is a high-grade aluminum alloy known for its excellent thermal conductivity and durability. This material effectively draws heat away from the Bridgelux or Citizen LED chip, maintaining stable performance and ensuring a long L80B10 lifespan of over 50,000 hours. It also provides a robust frame for the plaster-in installation process.

Q: What is the recommended setback and spacing for these wall washers?

A: For a standard 2.8-meter ceiling, a typical setback from the wall is 60 cm to 90 cm. The spacing between fixtures should be approximately equal to the setback distance to achieve uniform coverage without dark spots or overly bright overlaps. We highly recommend running a simulation in DIALux with our IES files for precise results.

Q: What is the lumen output for the 12W, 3000K, CRI90 version?

A: The 12W version with a 3000K, CRI90 Citizen LED chip and a high-efficiency Tridonic driver typically delivers a system lumen output of approximately 1150-1250 lumens. The exact output can vary slightly based on the specific driver and optical configuration chosen, and this data is detailed in the corresponding photometric report.

Q: Is the remote driver included with the fixture?

A: Yes, each D75 downlight is supplied as a complete system with a matched remote constant current driver. When you place an order, you will specify the required driver type (e.g., DALI-2, 0-10V, non-dim), and we provide the complete, tested package with a 5-year warranty covering both the fixture and the driver.
