Modular Orientable D90 Series LED Downlight 8-12W Factory

What is the Modular Orientable D90 Series and where is it specified?

At XHLWX (led-project-light.com), a Custom Indoor LED Lighting Manufacturer based in China, we engineered the Modular Orientable D90 Series LED Downlight as a versatile, high-performance lighting tool for architects, lighting designers, and electrical contractors targeting the European, US, and Middle Eastern markets. This 8-12W recessed luminaire combines a compact D90mm form factor with exceptional photometric flexibility. Its key feature is modularity; the core light engine can be paired with various trims and optics to suit projects from high-end retail and hospitality to modern offices and museums. The orientable design allows for precise aiming, making it an ideal solution for both general ambient lighting and specific accent or wall-washing applications. The fixture is designed for seamless integration into sophisticated control systems and meets stringent international quality standards.

Which spaces is it designed for?

This luminaire's modularity makes it a powerful tool for specifiers. The combination of high-quality light, multiple beam angles, and advanced control options allows it to adapt to various commercial environments demanding precision and ambiance.

How can I achieve focused accent lighting in a retail display or gallery?

For accenting merchandise, artwork, or architectural details, the D90 series excels. Specify the 15° or 24° beam angle options to create dramatic, high-contrast light shafts. Combined with a high CRI module (CRI>95) and a CCT of 3000K or 4000K, products and artworks are rendered with exceptional color accuracy and vibrancy. The orientable gimbal allows for precise aiming, ensuring light is placed exactly where needed, drawing customer attention and enhancing the perceived value of display items. For a typical retail display, aiming for 2000-3000 lux on the product is easily achievable.

What are the best practices for creating a welcoming atmosphere in hospitality settings?

In hotels, restaurants, and bars, the quality of light directly impacts guest experience. The D90 series offers several solutions. The Dim-to-Warm (DTW) option mimics the classic halogen dimming curve, shifting from 3000K at full output to a cozy 1800K when dimmed, perfect for evening ambiance. A standard 2700K or 3000K CCT with CRI>90 provides a warm, inviting, and high-quality feel. By using the wider 38° or 60° beam angles, you can create soft pools of light over seating areas, contributing to a comfortable and relaxed environment, while keeping glare to a minimum.

How does this luminaire contribute to a productive, low-glare office environment?

Modern office lighting must comply with standards like EN 12464-1, which mandates UGR<19 in task areas to reduce eye strain. The D90 series, when specified with the appropriate low-glare reflector and planned using DIALux simulation, meets this requirement. A 4000K CCT with CRI>90 is ideal for maintaining alertness and ensuring accurate color representation. Pairing these luminaires with a DALI-2 control system allows for daylight harvesting and individual control, optimizing both energy consumption and employee comfort. The flicker-free performance of our standard Tridonic and Osram drivers is critical for visual comfort in workspaces.

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

The D90 series is designed for straightforward installation with a cutout diameter of 75-80mm. It connects to a remote driver, allowing for easier maintenance and better thermal management. We offer full compatibility with a wide range of control protocols to meet any project requirement. For large-scale smart buildings, DALI-2 offers addressable control and feedback. For flexible, app-based wireless control in renovation projects or retail spaces, we offer Casambi (BLE) and Zigbee modules. Traditional 0-10V and TRIAC phase dimming options are also available for simpler installations. All our luminaires and standard drivers are fully certified with CE and RoHS markings, and our energy performance data supports ErP compliance for the European market.

Customisation, MOQ and lead time

As a custom lighting manufacturer, we offer extensive customisation. Beyond the options in the specification table, we can provide custom housing finishes (RAL colors), specific driver and chip combinations, and unique wiring solutions. The modular design allows for late-stage configuration, reducing risk for contractors.

Our Minimum Order Quantity (MOQ) for the D90 series is typically 100 units. For standard configurations, our production lead time is approximately 15-20 working days. For highly customized orders, lead time may extend to 25-30 days. We encourage you to discuss your project timeline with our sales engineering team.

Frequently Asked Questions

Q: What is the benefit of specifying CRI95+ over a standard CRI90?

A: While CRI>90 is excellent for most commercial applications, specifying CRI>95 or even CRI>98 provides superior color fidelity, essential for museums, galleries, and high-end retail. This ensures that colors, especially deep reds (R9 value >80), are rendered vividly and accurately, making textiles, artwork, and fresh produce look their absolute best. We also provide TM-30 data for a more complete color analysis.

Q: My project specifies a driver brand not on your list. Can you accommodate this?

A: Yes, this is a common request. While we standardize on Tridonic, Osram, and Mean Well for their reliability and 5-year warranties, we can source and integrate almost any driver brand you specify, including TCI, HEP, or Philips. This flexibility ensures our luminaires fit seamlessly into a building-wide specification. Just provide the driver part number, and we will confirm compatibility and pricing.

Q: How do I get photometric files for my lighting design software?

A: We provide full photometric support for designers. Complete IES and LDT photometric files for all variants of the D90 series are available upon request. These files allow you to accurately simulate the luminaire's performance in your DIALux or Relux projects, ensuring your design meets illuminance, uniformity, and UGR targets. Please contact our sales team with the specific product code (e.g., XH-CDLR-12W-ML) you require.

Q: What does the 5-year warranty cover?

A: Our comprehensive 5-year warranty covers the complete luminaire, including the LED module and the driver. It guarantees the product will be free from defects in material and workmanship. The performance warranty covers lumen depreciation (to L80B10 at 50,000 hours) and color shift (within a 3-step MacAdam ellipse). If a failure occurs within the warranty period, we will provide a replacement component or complete fixture.
