D110 series Surface Mounted LED Downlight 20-35w

What is the D110 series Surface Mounted LED Downlight and where is it specified?

At XHLWX (led-project-light.com), a Custom Indoor LED Lighting Manufacturer based in China, we engineer lighting solutions for demanding architectural specifications across the EU, US, and Middle East. The D110 series is a high-performance, cylinder-style surface mounted LED downlight designed for spaces where recessed installation is not feasible or desired. Its robust ADC12 aluminum construction and clean, minimalist aesthetic make it a versatile choice for concrete ceilings, historic buildings with sensitive surfaces, or modern commercial interiors seeking an industrial-chic look. Offering a power range from 20W to 35W within a compact D110mm x H135mm housing, it provides a powerful and adaptable solution for general, task, and accent lighting. Specifiers select the D110 for its exceptional flexibility in optical control, color quality, and system integration, making it a reliable workhorse for high-end retail, hospitality, and corporate environments.

Photometric and electrical specification

The D110 series is engineered to meet stringent European and North American performance standards. All configurations are supported by comprehensive IES and LDT files for seamless integration into DIALux and other lighting design software.

Which spaces is it designed for?

The D110's architectural form factor and highly configurable performance make it an ideal specification for a range of commercial applications where ceiling voids are absent or a surface-mounted aesthetic is preferred.

How can the D110 series enhance a retail or boutique environment?

For retail specifiers, precise color rendering is non-negotiable. The D110 series excels with CRI95+ and CRI98+ options, ensuring that the colors of merchandise, from fashion to fresh produce, are rendered accurately and attractively. Use the narrow 15° or 24° beam angles to create dramatic accent lighting, drawing a customer's eye to key displays with focused light levels exceeding 2000 lux. For general circulation paths, the wider 38° and 60° beams provide comfortable ambient light. The ability to customize reflector finishes—such as gold to complement a luxury brand's interior—adds another layer of design integration.

What makes this fixture suitable for hotel and hospitality projects?

In hospitality, atmosphere is paramount. The D110 addresses this through its wide range of CCTs and advanced dimming options. Specify 2700K or 3000K CCTs for a warm, welcoming ambiance in lobbies, corridors, and lounges. The 'Dim to Warm' option, which shifts from 3000K to a cozy 1800K glow as it dims, is perfect for creating intimate evening scenes in hotel bars and restaurants. Compatibility with control systems like DALI and Casambi allows for easy scene-setting and integration into the building's automation system, while its surface-mount design is a practical solution for solid or pre-cast concrete ceilings common in modern hotel construction.

Is this downlight compliant for modern office and commercial workspaces?

Yes, the D110 is engineered for human-centric lighting in today's workspaces. To comply with the European standard EN 12464-1 for office lighting, a luminaire over workstations must achieve a Unified Glare Rating (UGR) of less than 19. By specifying the D110 with a black internal reflector and a 38° or 60° optic, this UGR<19 requirement is met, ensuring visual comfort and reducing eye strain for employees. A 4000K CCT is typically recommended for promoting alertness and productivity. Full DALI-2 compatibility, including flicker-free drivers from brands like Tridonic, enables energy-saving strategies like daylight harvesting and presence detection.

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

Installation of the D110 is straightforward. The fixture ships with a mounting plate that is secured directly to the ceiling surface (plasterboard, wood, or concrete). The main body of the downlight then twists and locks onto the plate, with electrical connections made via a terminal block.

Control system integration is a core strength. We offer a comprehensive suite of drivers to match any specification:

• DALI-2: For addressable, digital control in smart buildings (IEC 62386). DT6 (brightness) and DT8 (Tunable White) drivers are available.
• 0-10V / 1-10V: A common analogue dimming standard for commercial projects.
• Phase-Cut (TRIAC): For leading/trailing edge dimming, suitable for retrofit projects using existing wiring.
• Wireless: Casambi (Bluetooth Low Energy) for app-based control and Zigbee 3.0 for integration into larger IoT ecosystems.

Compliance is assured for EU and global markets. The D110 series is fully CE certified (covering LVD and EMC directives), RoHS compliant, and meets ErP eco-design requirements. Our manufacturing facility operates under a certified ISO9001:2015 quality management system. Full IES and LDT photometric files are available for lighting simulation in software like DIALux EVO, enabling precise project planning and compliance verification.

Customisation, MOQ and lead time

As a lighting manufacturer, we provide extensive customisation to meet specific project needs. Beyond the standard options, we offer:

• Custom Finishes: While Matt White (RAL9016) and Matt Black (RAL9005) are stock finishes, we can produce the housing in any custom RAL color for a minimum order of 300 units.
• Driver Specification: If your project requires a specific driver model from brands like Tridonic, Osram, or others, we can source and integrate it.
• Optical Variations: We can work with you on modified beam angles or unique reflector combinations for large-scale projects.

The standard Minimum Order Quantity (MOQ) for the D110 series is 100 units. For pilot projects or mock-ups, smaller quantities can be discussed. Our typical production lead time is 20-25 working days from confirmation of order details to ex-works, subject to component availability and order volume.

Frequently Asked Questions

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

A: The D110 series comes with a comprehensive 5-year warranty. This covers defects in materials and workmanship for the entire fixture, including the LED module and the driver. The warranty guarantees performance to specifications, including lumen maintenance of at least L80B10 at 50,000 hours, ensuring long-term reliability for your commercial project and protecting your client's investment.

Q: Can I get this fixture with a UGR<19 rating for an office project?

A: Yes, achieving a UGR<19 rating is possible and is a common specification for office installations. To achieve this, you must combine the deep-set black internal reflector with either the 38° or 60° beam angle optic. This configuration minimizes high-angle light, ensuring compliance with EN 12464-1 for use over computer workstations and in conference rooms.

Q: What is the difference between Dim to Warm and Tunable White options?

A: Dim to Warm technology mimics the behavior of a traditional incandescent bulb, automatically shifting the color temperature from warm white (e.g., 3000K) to a very warm, amber glow (e.g., 1800K) as you dim the brightness. Tunable White allows for independent, user-controlled adjustment of both brightness and color temperature, typically within a range like 2700K to 6500K, for human-centric lighting applications.

Q: Are custom housing colors available?

A: Absolutely. While our standard finishes are Matt White (RAL9016) and Matt Black (RAL9005), we can accommodate custom powder coating to any color in the RAL classic chart. This service is available for projects with a minimum order quantity of 300 units per color, allowing you to perfectly match the luminaire to your client's interior design palette or corporate branding.
