Which spaces is it designed for?

The X20S-D240 is engineered for professional spaces where the quality of light directly impacts experience, comfort, and commercial outcomes. Its large aperture and high lumen output make it a workhorse for general illumination in areas with higher ceilings, while its optical precision allows for effective use in more focused applications. It serves as a single, scalable solution for projects spanning from bustling retail stores and hotel lobbies to quiet office corridors and conference rooms, ensuring consistent aesthetics and performance across a facility.

How can this downlight meet high-end retail lighting requirements?

For a European retail specifier, the X20S-D240 delivers on the key metrics that drive sales. With available CRI options up to CRI98 and excellent TM-30 metrics (Rf >90), it renders the colors of merchandise with exceptional accuracy and vibrancy. Use the narrow 15° or 24° beam angles to create dramatic accent lighting on mannequins or displays, achieving focal illuminance levels well over 1500 lux. For general circulation, the 38° and 60° beams provide comfortable, uniform light with a UGR<19, ensuring a pleasant shopping experience without distracting glare.

What makes it suitable for hotel lobbies and public areas?

In hospitality design, ambiance is paramount. The X20S-D240 excels with its available Dim-to-Warm (DTW) and Tunable White (TW) capabilities. A hotel lobby can transition from a bright, welcoming 4000K during daytime check-in to a warm, intimate 2700K or even 1800K in the evening, all from the same fixture. Full compatibility with control systems like DALI-2 and Casambi allows for easy integration into building management systems for automated scene-setting. Its robust build and 50,000-hour L80B10 lifetime ensure reliability in 24/7 operating environments.

Is the X20S-D240 a good choice for modern office general lighting?

Absolutely. For a US-based contractor or specifier, this downlight meets the stringent requirements for modern, human-centric office lighting. By selecting the 4000K CCT and an anti-glare reflector, the luminaire achieves a UGR<19, complying with WELL Building standards and European EN 12464-1 for visual comfort in spaces with computer screens. Its high system efficacy of up to 130 lm/W helps projects meet strict energy codes like Title 24 or ASHRAE 90.1. It is ideal for providing general illumination (300-500 lux) in open-plan offices, corridors, and large conference rooms.

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

Designed for straightforward installation by professional contractors, the X20S-D240 features a robust spring-clip mechanism that secures it into ceiling cutouts ranging from 200mm to 230mm. The driver is supplied externally for better thermal management and easier maintenance. We offer an unparalleled range of control protocol compatibility. Standard options include 0-10V, TRIAC (phase-cut) dimming, and DALI-2 for granular digital control. For smart and wireless projects, we offer drivers compatible with Casambi (Bluetooth Low Energy), ZigBee, and proprietary 2.4G RF systems. Full IES and LDT photometric files are available for seamless integration into DIALux, AGi32, and Relux lighting design software, enabling accurate project planning. The entire system is certified to meet CE (LVD/EMC), RoHS, and ErP directives, ensuring full compliance for the European market, backed by our ISO9001-certified manufacturing process.

Customisation, MOQ and lead time

As a direct manufacturer, we offer extensive customisation. Beyond the standard Matt White (RAL9016) and Matt Black (RAL9005) finishes, we can provide custom RAL powder coating to match any interior design scheme. We can configure the luminaire with different reflector finishes (e.g., specular, matt) and a wide array of color output technologies including Single Color, Tunable White (TW), Dim-to-Warm (DTW), and full-color RGBW. Our standard Minimum Order Quantity (MOQ) for the X20S series is 100 units. Typical production lead time is 20-25 working days from order confirmation, subject to final specification and component availability.

Frequently Asked Questions

Q: What is the warranty period for this modular downlight?

A: The X20S-D240 comes with a comprehensive 5-year warranty. This covers the LED module and the driver when specified with premium brands like Tridonic or Osram. The warranty ensures performance above L80B10 for 50,000 hours, offering long-term reliability for commercial projects and peace of mind for facility managers. We provide full support from our China-based factory.

Q: Can this downlight achieve a low glare rating for office use?

A: Yes, this downlight can be configured to achieve a Unified Glare Rating (UGR) of less than 19, which is crucial for office and educational environments. This is accomplished by combining our deep-set, anti-glare reflector with specific beam angles, like 38° or 60°. This configuration ensures visual comfort and compliance with European standard EN 12464-1 for interior workplaces.

Q: How flexible is the fixture regarding the ceiling cutout size?

A: The X20S-D240 is designed for a flexible cutout diameter ranging from 200mm to 230mm. Its robust spring clip system securely accommodates this range, making it an ideal choice for both new construction and retrofit projects where existing ceiling apertures may vary. The overall fixture diameter is 240mm, ensuring a clean overlap and a professional finish.

Q: What level of color rendering quality can I expect?

A: We offer exceptional color rendering options, including CRI90, CRI95, and up to CRI98 on specific CCTs like 3000K. For museum or high-end retail applications, we also provide TM-30 photometric data, often showing Rf values above 90 and Rg values around 100. This ensures not just color accuracy but also vibrant and saturated color appearance.
