Adjustable D90 Round LED Spot Downlight 10W supplier

What is the Adjustable D90 Round LED Spot Downlight 10W and where is it specified?

At XHLWX (led-project-light.com), a Custom Indoor LED Lighting Manufacturer based in China, we present the Adjustable D90 Round LED Spot Downlight 10W (Product code: XH-DL-10W-AR). This luminaire is an architectural-grade lighting tool engineered for precision, flexibility, and outstanding light quality. It is designed for specifiers, lighting designers, and contractors working on commercial, hospitality, and high-end residential projects across the EU, US, and Middle East. The fixture's core feature is its adjustability, allowing for 350° rotation and 30° tilt, enabling precise accent lighting that can adapt to evolving spaces. Its compact form factor, requiring only a Ø75mm cutout, makes it a discreet yet powerful solution for both new construction and retrofit applications. With exceptional color rendering options up to CRI98+ and a deeply recessed, low-glare design, it provides visual comfort without compromising on performance. To facilitate accurate project planning, full IES and LDT photometric files are available for seamless integration into DIALux lighting design software.

Which spaces is it designed for?

The D90 10W Adjustable Spot Downlight is a versatile workhorse luminaire. Its combination of a small aperture, powerful output, and high-quality optical control makes it suitable for creating layers of light in a variety of commercial environments, from focused accent lighting to comfortable general illumination.

How can this fixture be used to create accent lighting in a high-end retail boutique?

For high-end retail, creating drama and highlighting merchandise is paramount. The D90 excels here when specified with a narrow beam angle of 15° or 24°. This allows for the creation of high-contrast scenes, punching light onto mannequins, jewellery displays, or feature walls with illuminance levels exceeding 1500 lux. Specifying a high CRI of 95+ or even 98+ ensures that the true colors of fabrics, leathers, and cosmetics are rendered perfectly, directly impacting customer perception and sales. The 350° rotation and 30° tilt are invaluable for retail environments where displays change seasonally, allowing staff to re-aim lighting without tools.

What are the best practices for specifying this downlight in a hotel guest room or lobby?

In hospitality, the goal is to create a welcoming and comfortable atmosphere. For hotel guest rooms, we recommend using a warmer CCT of 2700K or 3000K. A wider 36° or 60° beam can provide soft general illumination, while a cluster of 15° versions can serve as focused reading lights above a headboard. Our Dim-to-Warm (DTW) option, which warms from 3000K to 1800K as it dims, is perfect for creating a cozy, residential feel. In lobbies, a mix of beam angles can create a sophisticated scheme: wider beams for circulation paths and narrow beams to highlight artwork, floral arrangements, or architectural details on a reception desk.

Can the D90 spot downlight achieve low glare ratings for office and educational environments?

Yes, absolutely. Visual comfort is critical in workspaces to reduce eye strain and improve productivity. The D90's optical design features a deeply regressed LED source and a standard black internal baffle, which work together to cut off stray light and achieve a Unified Glare Rating (UGR) of less than 19. This makes it fully compliant with standards like EN 12464-1 for lighting of workplaces. When used with a 4000K CCT and a 36° beam, it can provide comfortable and uniform illumination of 500 lux on desks in offices, meeting rooms, and school classrooms.

Installation, control and compliance

The D90 is designed for swift and secure installation by contractors. It fits into a standard Ø75mm ceiling cutout and is held in place by two robust spring clips. The luminaire is supplied with a remote, plug-and-play driver that simplifies wiring and can be placed in the ceiling void for better thermal management and easier maintenance access.

We offer a comprehensive range of control options compatible with global building management systems:

• DALI / DALI-2: For addressable digital control and energy monitoring in commercial buildings.
• 0-10V / 1-10V: A common analogue dimming protocol for simple, reliable dimming.
• TRIAC (Phase-cut): Suitable for leading/trailing edge dimmers, ideal for residential and hospitality retrofits.
• Wireless: Casambi (Bluetooth Low Energy) and ZigBee options are available for projects requiring minimal new wiring and smart, app-based control.

Compliance is assured with CE marking (covering LVD and EMC directives), RoHS for material safety, and ErP for energy efficiency, ensuring market access across Europe.

Customisation, MOQ and lead time

As a manufacturer, we thrive on customisation. Beyond the extensive photometric options, we offer physical customisation to meet your design intent. The standard housing finishes are a durable powder-coated Matt White (RAL9016) and Matt Black (RAL9005). For project orders exceeding 200 units, we can provide a custom finish to any RAL color code.

Our standard Minimum Order Quantity (MOQ) for the D90 series is 100 units. This allows us to maintain our quality control standards and offer competitive pricing. The typical production lead time is 15-20 working days from the confirmation of technical specifications and payment. Air and sea freight options are available globally, with shipping times varying by destination.

Frequently Asked Questions

Q: What is the standard warranty for the D90 10W LED Spot Downlight?

A: The D90 10W downlight comes with a comprehensive 5-year warranty covering the LED module and the driver. This warranty guarantees performance against defects in materials and workmanship, ensuring long-term reliability for commercial installations. Our L70 lifetime rating typically exceeds 50,000 hours, providing peace of mind for specifiers and facility managers.

Q: Can I get this fixture with a custom RAL finish to match my project's ceiling?

A: Absolutely. While our standard finishes are Matt White (RAL9016) and Matt Black (RAL9005), we frequently provide custom powder coating to any RAL classic colour code. This service is available for project orders, typically with a minimum order quantity of 200 units, to ensure a perfect match with your interior design scheme.

Q: What is the typical lumen output for a 3000K, CRI90 version?

A: For a standard 10W D90 Spot Downlight configured at 3000K with a CRI of 90+, you can expect a delivered lumen output of approximately 950 to 1050 lumens. This translates to an excellent efficacy of 95-105 lm/W. The exact output can vary slightly based on the selected beam angle optic and driver configuration.

Q: Is the driver included with the downlight, and is it remote or integral?

A: Yes, each D90 downlight is supplied with a high-quality, flicker-free external driver from trusted brands like Tridonic or Osram. The driver is remote, connected via a simple plug-and-play connector. This configuration improves thermal management for the LED chip, extending its lifespan, and allows for easier installation and maintenance access through the Ø75mm cutout.
