Which spaces is it designed for?

This luminaire is a versatile tool for creating layered, high-impact lighting schemes. Its performance characteristics make it a preferred choice for specifiers working on demanding projects in Europe and the United States.

How to achieve dramatic accent lighting in a luxury retail boutique?

The D90 10W spot is perfect for this application. Using the narrow 15° or 24° beam angle, you can precisely highlight handbags, jewelry, or apparel, creating high-contrast focal points that attract customers. With a CRI95+ chip, colours appear vibrant and true. A well-designed scheme can achieve illuminance levels of over 1500 lux on key merchandise, making products pop. The adjustable head allows for quick reconfiguration as store layouts change.

Creating an inviting atmosphere in a hotel guest room or lobby?

For hospitality, the quality of light is paramount. We recommend the 3000K CCT option with a CRI >90 and a 36° beam for a warm, welcoming, and spacious feel. The optional Dim-to-Warm (DTW) functionality, which shifts CCT from 3000K down to 1800K as it dims, mimics traditional halogen lighting, creating a cozy and intimate ambiance perfect for evening relaxation. The fixture's low UGR<19 rating ensures guests experience comfortable, glare-free light.

What is the best solution for flexible lighting in a modern art gallery or museum?

Galleries require uncompromising color accuracy and the flexibility to light rotating exhibitions. The D90 with a CRI98+ LED chip and a full set of IES and LDT photometric files allows for precise planning in software like DIALux. The adjustable head and interchangeable 15°, 24°, and 36° lenses give curators the tools they need to perfectly frame each piece. Integration with a DALI-2 control system allows for individual luminaire control and the creation of complex scenes, ensuring each artwork is rendered exactly as the artist intended.

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

The XH-PL-10W-AS is designed for straightforward installation with a required cutout of 75x75mm. It is secured into plasterboard or other ceiling materials via robust spring clips. The luminaire connects to an external driver, offering maximum flexibility in control protocols. We provide drivers compatible with leading systems including DALI-2 for granular digital control, 0-10V/1-10V for simple analog dimming, and TRIAC for retrofit projects. For wireless control, we offer solutions compatible with Casambi (BLE) and Zigbee. All our driver and luminaire combinations are fully CE certified (covering LVD and EMC directives), RoHS compliant, and meet ErP regulations for the EU market, ensuring a smooth specification and import process.

Customisation, MOQ and lead time

As a manufacturer, we thrive on customization. Beyond standard CCTs and beam angles, we offer Tunable White (2700K-6500K), Dim-to-Warm (3000K-1800K), and full-colour RGBW models. The standard housing finishes are Matt White and Matt Black, but we can provide custom RAL finishes for orders meeting our Minimum Order Quantity (MOQ) of 200 units. The standard MOQ for this product is 100 units. Our typical production lead time is 15-25 working days from confirmation of technical specifications, with shipping to the EU or US typically taking an additional 30-40 days by sea.

Frequently Asked Questions

Q: What is the warranty on the D90 LED Spot Downlight?

A: We provide a comprehensive 5-year warranty for the complete luminaire, including the LED chip and the external driver. This covers failures or significant performance degradation outside of stated specifications. Our use of world-class components from brands like Citizen, Bridgelux, Tridonic, and Osram ensures long-term reliability and peace of mind for your project.

Q: Are photometric files available for lighting design simulations?

A: Absolutely. We provide complete photometric data for lighting designers and specifiers. Upon request, we can supply both IES and LDT format files for all available beam angle options. This data allows for accurate simulation and calculation of illuminance, luminance, and UGR values in lighting design software such as DIALux, Relux, and AGI32.

Q: What is the typical UGR rating I can expect from this fixture?

A: When using the 24° or 36° lens options in a properly designed layout, achieving a Unified Glare Rating (UGR) of less than 19 is standard, making it compliant for office and commercial spaces. For applications requiring extremely low glare, such as VDU workstations, a UGR of <16 can be achieved with careful placement and the deep-recessed optic.

Q: What are the exact cutout dimensions for the 10W model?

A: The 10W D90 model, product code XH-PL-10W-AS, requires a square ceiling cutout of 75mm x 75mm. It is critical to use this dimension for a secure and clean installation. Please note that other models in the series, like the 15W D115, have different cutout requirements (95x95mm), so always verify the datasheet for the specific model being installed.
