Which spaces is it designed for?

The X20S-D200 is engineered as a versatile tool for professional lighting schemes in a variety of commercial settings. Its combination of high output, excellent color quality, and visual comfort makes it suitable for spaces where ambient and accent lighting must perform flawlessly. Primary applications include high-end retail, hospitality (hotels, restaurants), corporate offices, educational facilities, and art galleries.

How can I use the X20S-D200 to achieve layered lighting in a retail environment?

For a dynamic retail space, the X20S-D200's modularity is key. Use the 35W version with a narrow 15° or 24° beam angle to create powerful accent lighting, punching down onto merchandise displays to achieve focal points with over 1500 lux. Specify a CRI95+ or CRI98+ chip to ensure product colors from textiles to fresh produce are rendered with maximum fidelity. For general circulation paths, switch to the 20W version with a wide 60° beam angle for comfortable ambient illumination around 300-500 lux, ensuring a smooth, layered lighting effect that guides customers through the store.

What makes this downlight suitable for high-ceiling hotel atriums or conference rooms?

In spaces with ceiling heights from 4 to 7 meters, such as hotel lobbies or large conference rooms, the 35W X20S-D200 delivers the necessary lumen package (up to 4550 lumens) to effectively illuminate the floor level. The deep-set LED source and high-quality reflector optics maintain strict beam control, minimizing light spill and glare. For conference rooms, specifying the UGR<19 configuration ensures visual comfort for seated occupants, even during presentations. The robust die-cast aluminum heat sink ensures stable performance and long life, even when operated for extended hours.

Can this fixture be adapted for human-centric lighting in modern office spaces?

The X20S-D200 fully supports human-centric lighting (HCL) strategies through its Tunable White (TW) option. By specifying a TW version, you can dynamically adjust the color temperature from a warm 2700K to a cool 6500K. This allows the lighting to mimic the natural progression of daylight, potentially improving employee alertness and well-being. Integrated with a DALI-2 control system, you can program scenes to provide cool, energizing light (e.g., 5000K) mid-day and warmer, more relaxing light (e.g., 3000K) in the morning and late afternoon, creating a more responsive and productive workspace.

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

Installation is streamlined for professional contractors. The X20S-D200 requires a ceiling cutout between 170mm and 190mm and is secured by robust, pre-installed spring clips. The external driver allows for easier maintenance and flexibility in ceiling voids. We offer an extensive range of control options compatible with global standards:

• DALI-2: For addressable, digitally controlled systems offering maximum flexibility and data feedback.
• Casambi/BLE: For app-based wireless mesh control, perfect for retrofits or spaces where new control wiring is impractical.
• 0-10V / 1-10V: A reliable and widely understood analog dimming protocol.
• TRIAC (Phase Dimming): For compatibility with leading/trailing edge wall dimmers.

The luminaire is fully certified with CE, RoHS, and ErP, ensuring compliance for projects throughout the European Union. Our manufacturing processes are certified under ISO9001, guaranteeing consistent quality control.

Customisation, MOQ and lead time

As a direct manufacturer, we provide extensive customisation. Beyond the standard options, we can supply custom RAL color finishes, specific non-standard CCTs, or pre-fit drivers from a brand of your choice.

The Minimum Order Quantity (MOQ) for the X20S-D200 series is 50 units.

The standard lead time for production is approximately 15-20 working days, with shipping time dependent on the final destination in the EU, US, or Middle East. We can accommodate urgent project timelines; please discuss your schedule with our sales engineers.

Frequently Asked Questions

Q: What is the warranty on the X20S-D200 and what does it cover?

A: The X20S-D200 comes with a comprehensive 5-year warranty. This covers the entire luminaire, including the LED chip, driver, and housing. It guarantees performance against component failure and ensures lumen output remains above 80% of its initial value (L80B10) for 50,000 hours of operation under normal conditions.

Q: What is the expected system efficacy for a 3000K, CRI90+ model?

A: For a typical X20S-D200 configuration at 30W with a 3000K CCT and CRI90+ chip, paired with a high-efficiency Tridonic driver, you can expect a system efficacy of approximately 95-105 lumens per watt. This configuration would yield a total light output of around 2850-3150 lumens.

Q: How large of a cutout is required for installation?

A: The X20S-D200 is designed for flexibility, fitting into a circular ceiling cutout with a diameter ranging from 170mm to 190mm. The luminaire's powerful spring clips will securely fasten it within this range, making it suitable for both new construction and retrofitting existing large-format downlight apertures.

Q: Can I get a sample for a project evaluation in the United States?

A: Yes, we regularly provide samples for project evaluation to architects and designers in the US and worldwide. We can ship samples via express air freight, typically arriving within 5-7 business days. Please contact our sales team to discuss your project requirements and arrange for a sample shipment.
