Double head adjustable D90 Series LED downlight 2*10W

What is the D90 Series Double Head Adjustable 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 XH-PL-2*10W-AS, a core product in our D90 Series of adjustable twin-head recessed downlights. This luminaire is engineered for commercial applications requiring dynamic and high-quality accent, task, or general illumination. Featuring two independently adjustable 10W heads within a single compact housing (90x170x92mm), it offers exceptional flexibility for designers and contractors targeting precise light placement from a minimalist ceiling cutout of just 75x155mm. Its primary application is in projects across the EU, US, and Middle East where performance, colour quality, and directional control are paramount.

Photometric and Electrical Specification

The XH-PL-2*10W-AS is built to meet demanding European and North American project specifications. We provide complete IES and LDT photometric files for lighting simulation software like DIALux to ensure performance is validated before installation.

Which spaces is it designed for?

The dual-head adjustability and high-quality light output of the D90 series make it a versatile tool for lighting specifiers. It replaces two single spotlights with a cleaner, consolidated ceiling aesthetic, reducing installation time and complexity while increasing lighting design flexibility. It is ideal for spaces that benefit from layered lighting, including retail environments, hospitality venues, modern offices, and galleries.

How can it be used to highlight merchandise in a high-end retail store?

In a retail setting, the D90 downlight excels at creating powerful accent lighting. Use the narrow 15° or 24° beam angles to punch light onto specific products like jewelry, apparel, or electronics, making them stand out. With CRI95+ or CRI98+ options, colours appear vibrant and true-to-life. The dual heads allow a single fixture to illuminate two separate displays or to cross-light a single larger object, sculpting it with light and shadow to create depth and visual interest.

What makes it suitable for hotel lobbies or restaurant dining areas?

For hospitality, atmosphere is key. The D90 provides the flexibility to create it. Specify a warm CCT of 2700K or 3000K and integrate with a DALI or 0-10V dimming system to transition from bright, welcoming daytime scenes to intimate, low-level evening ambience. The low glare design (UGR<19) ensures visual comfort for guests. One head can be aimed at a table for functional task lighting, while the other can be directed towards an architectural feature or artwork, creating a sophisticated, layered environment from a single fixture point.

Can this fixture provide effective task lighting in an office or gallery?

Absolutely. In modern office breakout zones or collaboration areas, the D90 can provide focused task lighting, delivering over 500 lux on a tabletop when required. Using a neutral 4000K CCT creates a productive environment. For art galleries, the fixture's high CRI and range of beam angles are critical. The 355° rotation and 30° tilt on each head allow for precise aiming to perfectly frame artwork, while the ability to specify museum-grade LED chips (CRI98+) ensures faithful colour representation without damaging IR or UV radiation.

Installation, Control, and Compliance

Installation is streamlined for professional contractors. The fixture requires a rectangular cutout of 75x155mm and is secured by robust, pre-installed spring clips suitable for plasterboard ceilings. The luminaire is powered by a remote, constant current driver, allowing for easier maintenance and thermal management. We offer comprehensive control protocol support, including standard mains TRIAC dimming, 0-10V analog, and DALI-2 digital addressable control. For smart building projects, wireless options like Casambi (Bluetooth Low Energy) are available upon request. All configurations are CE and RoHS certified for the European market and comply with ErP directives. Our manufacturing process is ISO9001 certified, guaranteeing consistent quality.

Customisation, MOQ, and Lead Time

As a lighting manufacturer, we specialise in customisation. Beyond the standard Matt White (RAL9016) and Matt Black (RAL9005) finishes, we can produce the D90 series in any RAL colour to match your project's interior design palette. CCT, CRI, and driver brand can all be specified to meet exact performance or budget requirements. The minimum order quantity (MOQ) for this series is typically 100 units. Standard production lead time is approximately 15-25 working days, depending on customisation complexity and order volume.

Frequently Asked Questions

Q: What is the warranty period for the D90 2x10W downlight?

A: We provide a comprehensive 5-year warranty on the complete luminaire, including the ADC12 aluminum housing, LED chips, and the specified external driver from brands like Tridonic or Osram. This warranty covers defects in materials and workmanship, ensuring long-term reliability for your commercial project. Our L80B10 rating guarantees at least 80% lumen maintenance after 50,000 hours of operation.

Q: What is the range of colour rendering and colour temperature available?

A: You can specify CCTs from a very warm 2700K up to a cool daylight 6500K. For colour-critical applications like retail or museums, we offer high colour rendering options including CRI>90, CRI>95, and CRI>98. All options maintain excellent colour consistency with a rating of SDCM <3, preventing noticeable colour shifts between fixtures.

Q: Are there different dimming protocols supported?

A: Yes, the fixture is highly compatible with modern control systems. We can supply drivers for leading-edge/trailing-edge (TRIAC) dimming, 0-10V analog dimming, and DALI-2 digital control for individual addressing and scene-setting. For retrofit or wireless projects, we also offer solutions compatible with Casambi Bluetooth mesh and ZigBee 3.0 systems upon request.

Q: How much can each head be tilted and rotated?

A: Each of the two 10W heads is independently adjustable for maximum flexibility. They can be rotated horizontally through 355 degrees and tilted vertically up to 30 degrees. This wide range of motion allows you to precisely direct two beams of light from a single ceiling position, perfect for accenting, wall-washing, or cross-lighting objects.
