Professional X20S-D110 Modular LED Downlight 10-25W

What is the Professional X20S-D110 Modular 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 Professional X20S-D110 series—a highly versatile and modular LED downlight engineered for demanding commercial specification markets in Europe, the US, and the Middle East. This luminaire is designed as a complete lighting solution, offering selectable power outputs from 10W to 25W within a single, consistent D110mm housing. Its primary advantage lies in its modularity, allowing specifiers to precisely tailor the light output, colour quality, beam control, and dimming protocol for each specific application, from general ambient lighting to focused accenting. With options for museum-grade CRI up to 98+, a full spectrum of CCTs from a warm 2700K to a cool 6500K, and a UGR<19 rating, the X20S-D110 is the definitive choice for architects, lighting designers, and contractors seeking performance, flexibility, and reliability in one package.

Which spaces is it designed for?

The X20S-D110's modular design makes it an exceptional tool for lighting designers working on a variety of commercial interior projects. Its ability to provide both high-quality ambient and accent lighting from a single form factor streamlines specification and installation. It is particularly effective in high-end retail, hospitality (hotels, restaurants), corporate offices, and cultural spaces like museums and galleries where light quality directly impacts experience and perception.

How can this downlight enhance a retail or hospitality environment?

For a luxury boutique or hotel lobby, the X20S-D110 delivers exceptional visual impact. By specifying a high CRI 95+ or CRI 98+ version, you ensure that textiles, materials, and merchandise are rendered with vibrant accuracy, encouraging customer engagement. The 15° or 24° narrow beam options are perfect for creating dramatic accent lighting on displays, artwork, or architectural features, achieving high lux levels (e.g., >1500 lux) on target. For general circulation areas, the 38° or 60° beams provide comfortable, uniform illumination from the same luminaire family, ensuring a cohesive aesthetic.

What makes the X20S-D110 suitable for office and conference room lighting?

In modern workspaces, visual comfort is paramount for productivity and well-being. The X20S-D110 addresses this by using a combination of a deep-set LED source and high-performance optics to achieve a Unified Glare Rating (UGR) of less than 19, complying with the European standard EN 12464-1 for office lighting. When paired with a DALI-2 driver, it can be integrated into intelligent building control systems for daylight harvesting or scene-setting in conference rooms. The flicker-free performance of premium drivers from Tridonic or Osram ensures a comfortable environment for all-day use.

Can the fixture be adapted for museum or gallery lighting specifications?

Absolutely. Museum-grade lighting requires precision and preservation. The X20S-D110 meets these needs with its CRI 98+ option and tight color consistency (SDCM <3), ensuring that artworks are displayed as the artist intended, fixture to fixture. The range of CCTs from a warm 2700K to a neutral 4000K allows curators to create the desired ambiance. Furthermore, we provide complete IES and LDT photometric files for every variant, allowing designers to run precise calculations in DIALux to verify illuminance levels and uniformity before installation, protecting sensitive artifacts from excessive light exposure.

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

Installation is simplified by a robust spring-clip mechanism designed for ceiling thicknesses from 5mm to 25mm, fitting a standard cutout of 90-105mm. The external driver allows for a lower fixture height and improved thermal management.

Control flexibility is a core feature. We offer drivers for all major protocols:

• Wired: DALI-2 (including DT6 and DT8 for Tunable White), 0-10V/1-10V, and Phase-cut (TRIAC).
• Wireless: Bluetooth Low Energy (BLE) via Casambi, as well as ZigBee, 2.4G RF, and DMX for dynamic color applications (RGBW).

The X20S-D110 is fully certified for the European market with CE (LVD/EMC) and RoHS compliance. ErP documentation is available to confirm energy efficiency performance. All products are manufactured in our ISO9001:2015 certified facility.

Customisation, MOQ and lead time

As a manufacturer, we specialise in tailoring products to project requirements. Beyond the standard options, we can provide custom RAL finishes, specific CCTs, or integrate drivers from other specified brands. The modular design allows for a high degree of customisation even on smaller project orders.

• Minimum Order Quantity (MOQ): 100 units.
• Standard Lead Time: 15-25 working days from order confirmation to dispatch.

Frequently Asked Questions

Q: What is the typical luminous efficacy I can expect?

A: The system efficacy for the X20S-D110 ranges from 80 to 130 lumens per watt (lm/W). This performance depends on your selected configuration; for example, a 20W, 4000K, CRI80 model will operate at the higher end of this range, around 125 lm/W, while a 25W, 2700K, CRI98+ version will be closer to 85 lm/W due to the nature of high-CRI phosphors.

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

A: We provide a comprehensive 5-year warranty on the complete X20S-D110 luminaire, which includes the LED module and the external driver. This warranty covers manufacturing defects and failures under normal operating conditions. The high-quality Citizen or Bridgelux LEDs used are rated for a L80B10 lifetime exceeding 50,000 hours, ensuring long-term performance and reliability.

Q: Can I get a version with Tunable White or Dim-to-Warm?

A: Yes, the X20S-D110 platform is fully capable of advanced color tuning. We offer Tunable White (TW) versions, typically ranging from 2700K to 6500K, controlled via DALI DT8 drivers. Dim-to-Warm (DTW) options are also available, which smoothly transition from a bright 3000K down to a very warm 1800K glow as the fixture is dimmed, perfectly mimicking halogen lamps.

Q: What cutout size is required for installation?

A: The X20S-D110 downlight is designed for a versatile ceiling cutout diameter ranging from 90mm to 105mm (3.5 to 4.1 inches). The luminaire's trim has an outer diameter of 110mm, which provides a clean 2.5-10mm overlap to cover any minor imperfections in the ceiling cut, ensuring a professional finish. Two robust spring clips secure the fixture firmly in place.
