D90 Series Surface Mounted LED Pendant Light 20-35W

What is the D90 Series and where is it specified?

At XHLWX (led-project-light.com), a Custom Indoor LED Lighting Manufacturer based in China, we design and produce architectural lighting solutions for professional specification in the European, North American, and Middle Eastern markets. The D90 Series is a high-performance, surface-mounted LED pendant light representing the pinnacle of versatility and minimalist design. Its clean, cylindrical form factor (D85x170mm) and robust die-cast aluminium construction make it an ideal choice for projects demanding both aesthetic elegance and technical precision. Available in a flexible power range from 20W to 35W, the D90 is engineered for applications where direct, high-quality illumination is paramount, from task lighting over workstations to dramatic accenting in hospitality and retail environments. It provides a sophisticated, modern alternative to traditional downlights, especially in spaces with high ceilings or where recessed installation is not feasible.

Photometric and electrical specification

The D90 Series is built to meet stringent European and US project requirements. Every component, from the LED chip to the external driver, can be configured to match precise lighting design criteria. We provide full documentation, including IES and LDT photometric files, for seamless integration into DIALux and other lighting design software.

Which spaces is it designed for?

The D90 Series' configurable nature makes it an exceptionally adaptable luminaire. Its primary value lies in delivering controlled, high-quality light from a discreet and modern fixture, suitable for general, task, or accent lighting.

How can the D90 Series enhance hotel lobby and restaurant lighting?

In hospitality settings, creating ambiance is key. The D90 excels at this by providing warm, inviting light. Specifying a 2700K or 3000K CCT with a high CRI (>95) ensures that interior finishes, artwork, and even food are rendered beautifully and accurately. Using a narrow 24° beam angle, you can create dramatic pools of light over individual restaurant tables, achieving intimate light levels of 300-400 lux while keeping surrounding circulation paths darker. For lobbies, a wider 60° beam can provide comfortable general illumination from high ceilings, while DALI dimming integration allows for seamless transitions from bright daytime scenes to subdued evening moods.

What makes it suitable for modern office and co-working environments?

For modern workplaces, visual comfort and compliance with lighting standards are non-negotiable. The D90 Series, when specified with its anti-glare optics, achieves a UGR<19, a critical requirement for preventing glare on computer screens as per the European standard EN 12464-1. A 4000K CCT is typically recommended to promote alertness and concentration. When suspended over collaborative zones, conference tables, or individual workstations, the D90 provides effective task lighting. Its pendant form adds architectural interest compared to standard ceiling panels, contributing to a more dynamic and contemporary office design.

How does it perform in retail and gallery applications?

In retail and gallery contexts, light is a tool to attract attention and reveal the true quality of objects. The D90's key advantage here is its exceptional color rendering capabilities, with options for CRI >98 and TM-30 metrics that guarantee colors are shown with the highest fidelity. A narrow 15° or 24° beam is perfect for creating strong accent lighting on mannequins, feature displays, or artworks, making them stand out. By arranging multiple pendants in a linear or grid formation, you can create a guided path for customers or illuminate entire walls of merchandise with focused, high-impact light, enhancing perceived value and driving sales.

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

The D90 is designed for straightforward surface-mounted installation onto standard ceiling junction boxes. Its two-part canopy conceals the wiring and driver connection, ensuring a clean, seamless finish. As a custom manufacturer, we offer unparalleled flexibility in control systems. The luminaire can be supplied with drivers compatible with virtually any modern protocol, including:

• DALI-2: For sophisticated, addressable control in large commercial projects, allowing for individual luminaire dimming, scene-setting, and energy monitoring.
• Casambi/BLE: For wireless Bluetooth Low Energy mesh control, ideal for retrofit projects or spaces where running new control wiring is impractical.
• 0-10V & 1-10V: A robust and widely used analog dimming standard for simple, reliable dimming.
• TRIAC (Phase-cut): For compatibility with leading-edge or trailing-edge wall dimmers, common in residential and small-scale commercial applications.

All configurations are supplied with CE marking, attesting to compliance with EU Low Voltage and EMC Directives. The luminaires are also RoHS compliant and designed to meet the latest ErP ecodesign requirements for energy efficiency. Our manufacturing process is certified under ISO9001, guaranteeing consistent quality control. Full IES and LDT photometric files are available for all standard configurations to facilitate accurate lighting simulations in DIALux and other platforms.

Customisation, MOQ and lead time

We specialize in tailoring products to meet precise project demands. Customisation for the D90 Series includes non-standard CCTs, specification of Dim-to-Warm or Tunable White LED modules, and custom housing finishes in any RAL color to match brand guidelines or interior design schemes. Our standard finishes are Matt White (RAL9016) and Matt Black (RAL9005).

The minimum order quantity (MOQ) for the D90 Series is typically 50 units. This allows us to optimize production and maintain competitive pricing for professional projects. For smaller sample orders, please contact our sales team. Our standard production lead time is approximately 15-25 working days from the date of order confirmation and drawing approval, with shipping time dependent on the final destination in the EU, US, or Middle East.

Frequently Asked Questions

Q: What is the warranty on the D90 Series LED pendant?

A: The D90 Series comes with a comprehensive 5-year manufacturer's warranty. This covers the entire luminaire, including the LED module and the specified driver (e.g., Tridonic, Osram). We guarantee performance to L80B10 at 50,000 hours, ensuring long-term reliability and light output for professional installations.

Q: How are the different dimming options specified?

A: Dimming compatibility is determined by the external driver. During the quotation phase, you simply specify your required control protocol—such as DALI-2, 0-10V, Casambi (BLE), or TRIAC. We will then pair the D90 pendant with a premium, certified driver from a brand like Tridonic or Osram that matches your system's needs.

Q: What are the best color rendering options for museum or gallery use?

A: For color-critical applications, we recommend specifying our CRI >98 option. This high-fidelity LED provides museum-grade color accuracy. For even greater detail, request the TM-30 report for this option, which typically shows an Rf (fidelity) value above 95 and an Rg (gamut) value over 100, ensuring vibrant and true-to-life color rendition.

Q: What is the recommended installation height?

A: For general ambient lighting using a 60° beam, an installation height of 2.8 to 4 meters is effective. For accenting a standard dining or boardroom table (0.75m height), suspending the pendant 2.0 to 2.2 meters above the floor with a 24° or 38° beam will create a well-defined pool of light achieving 300-500 lux.
