Which spaces is it designed for?

The D140 Series is a highly adaptable tool for lighting designers and electrical contractors targeting premium commercial interiors. Its specification-grade features address the specific demands of various environments across Europe and the United States.

How can this downlight enhance luxury retail displays and showrooms?

For luxury retail, color fidelity is non-negotiable. The D140's high-CRI options (CRI>95, CRI>98) ensure that the colors of fabrics, leather goods, and jewelry are rendered accurately and vibrantly, influencing customer perception and purchasing decisions. The adjustable 355° rotation and 30° tilt, combined with narrow beam angles like 15° and 24°, allow for precise accenting of merchandise. This creates dramatic focal points and achieves high illuminance levels (e.g., 1500-2000 lux) on key displays, making them stand out within the ambient store lighting. The low-glare design (UGR<19) keeps the focus on the products, not the light source.

What makes the D140 suitable for creating ambiance in hotel lobbies and restaurants?

In hospitality environments, lighting must create a welcoming and comfortable atmosphere. The D140 excels here with its wide range of warm CCTs (2700K, 3000K) and Dim to Warm (DTW) options, mimicking the cozy glow of incandescent sources as they are dimmed. Compatibility with DALI-2 and Casambi control systems allows for the creation of dynamic lighting scenes that adapt from a bright, welcoming daytime setting to a subtle, intimate evening mood. The UGR<19 rating is critical in seating areas and corridors, preventing discomfort for guests and contributing to an overall sense of luxury and relaxation.

Can this fixture be used for modern office and conference room lighting?

Yes, the D140 is an excellent choice for modern human-centric office lighting. In workspaces and conference rooms, controlling glare is essential for employee well-being and productivity. The D140's design inherently delivers a UGR<19, complying with the EN 12464-1 standard for office lighting. Specifying a neutral 4000K CCT can promote alertness, while its integration with DALI-2 allows it to be part of a smart building's lighting management system, enabling daylight harvesting and occupancy sensing to reduce energy consumption by up to 60%. The adjustable nature is perfect for accenting architectural details or providing focused light over collaboration tables.

Installation, control and compliance

The D140 Series is designed for straightforward installation by professional contractors. It requires a square ceiling cutout of 115x115mm and is secured via robust, pre-installed spring clips, ensuring a firm and flush fit in plasterboard or suspended ceilings. The luminaire connects to a remote driver, which simplifies maintenance and thermal management.

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

• Wired: DALI-2 for interoperable digital control, 0/1-10V for simple analog dimming, and TRIAC for phase-cut dimming in retrofit projects.
• Wireless: Casambi (Bluetooth Low Energy) for app-based control and mesh networking, and Zigbee for integration into larger smart building ecosystems.

For project planning, complete photometric data in IES and LDT photometric files format is available on request. These files allow for precise and reliable lighting simulations in software like DIALux Evo, ensuring the final installation meets the design intent and regional lighting codes. The product is fully certified with CE, RoHS, and ErP for the European market. For US projects, we configure the luminaire with UL or ETL-listed drivers to meet local compliance requirements.

Customisation, MOQ and lead time

As a manufacturer, XHLWX excels at tailoring products to specific project needs. Beyond standard options, the D140 series can be customized in several ways. We can accommodate specific CCT requests, supply custom-painted housing in any RAL color to match brand aesthetics or interior design palettes, and integrate specialized optics or color-tuning technologies like RGBW.

Our production is geared towards project-based orders. The Minimum Order Quantity (MOQ) for the D140 series is typically 100 units. This allows us to maintain strict quality control and offer competitive pricing. The standard production lead time is approximately 20-25 working days from order confirmation to dispatch from our facility in China. We work closely with international freight forwarders to ensure timely delivery to your project site in the EU, US, or Middle East.

Frequently Asked Questions

Q: What is the rotational and tilt adjustment range of the D140 downlight?

A: The D140 Series offers excellent directional flexibility with a 355° horizontal rotation and a 30° vertical tilt. This allows for precise aiming of the light beam after installation, making it ideal for accenting specific architectural features, artwork, or retail displays. The mechanism is engineered for smooth, stable adjustment without requiring tools, locking securely in place once positioned.

Q: What is the typical lumen output for the 25W version at 4000K with CRI>90?

A: For the 25W configuration (XH-PL-25W-AS) at a neutral 4000K CCT and a high CRI of >90, the typical delivered lumen output is approximately 2,750 lumens. This is based on an efficacy of around 110 lm/W. The exact output can vary slightly based on the selected beam angle and other factors, and precise data is available in the IES files for your specific configuration.

Q: Are different anti-glare baffle colors available?

A: Yes. While the standard options are a black baffle for the lowest UGR and a white baffle for a more seamless ceiling appearance, we can provide custom finishes. For project orders, we can supply baffles in gold, silver, or a specified RAL color. This customization allows lighting designers to use the fixture's interior as a subtle design element, with a lead time extension of 5-7 days.

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

A: The D140 Series LED Spot Downlight comes with a comprehensive 5-year warranty. This warranty covers the entire luminaire, including the LED light engine and the remote driver, against any manufacturing defects or premature failure under normal operating conditions. It guarantees a lumen maintenance of at least L80B10 after 50,000 hours, ensuring long-term performance and peace of mind for your investment.
