Double head adjustable D115 Series LED downlight 2*10W

What is the D115 Series Adjustable Downlight and where is it specified?

At XHLWX (led-project-light.com), a Custom Indoor LED Lighting Manufacturer based in China, we engineer precision lighting solutions for commercial applications across Europe, the US, and the Middle East. The D115 Series, specifically the model XH-PL-2*15W-AS, is a high-performance recessed dual-head adjustable LED downlight. It combines two powerful 15W light sources in a single, compact housing, offering exceptional flexibility for accent and general lighting. Each head can be independently tilted and rotated, allowing lighting designers and contractors to precisely direct light to two different areas from a single fixture point. This reduces ceiling clutter while maximizing functionality, making it an ideal choice for sophisticated retail, hospitality, and gallery projects where adaptability and quality of light are paramount.

Photometric and electrical specification

The D115 Series is designed to meet stringent international project requirements. We provide full transparency on component and performance data, enabling accurate specification for demanding environments.

Which spaces is it designed for?

The D115 dual-head downlight's core strength is its versatility. The ability to aim two beams of light from one point solves numerous challenges in commercial interior design. It's engineered for spaces that require dynamic, multi-layered lighting schemes, such as high-end retail stores, hotel lobbies, corridors, restaurants, art galleries, and modern office environments.

How can this fixture create focused accent lighting in a retail environment?

In a retail setting, the D115 excels at creating high-impact displays. A single fixture can be used to simultaneously highlight two different product displays or a mannequin and adjacent signage. By selecting a narrow beam angle like 15° or 24° and a high-CRI option (CRI>95), retailers can render product colors with exceptional accuracy and create focal points with illuminance levels exceeding 1000 lux. The independent adjustability (355° rotation, 30° tilt) ensures that as store layouts change, the lighting can be easily reconfigured without moving the fixtures.

What makes it suitable for hotel lobbies and corridors?

For hotel common areas, this fixture provides a sophisticated, layered lighting approach from a minimalist ceiling profile. In a lobby, one head can be aimed with a wider 36° beam to contribute to the ambient circulation light, while the second head uses a 24° beam to accent a piece of art or a floral arrangement. In corridors, it can wash one wall while simultaneously highlighting room number plaques on the opposite wall. The availability of warm CCTs like 2700K and 3000K, combined with excellent glare control (UGR<19), creates a comfortable and welcoming atmosphere for guests.

Can this downlight be used for museum and gallery lighting?

Yes, the D115 is an excellent tool for museum and gallery applications when specified correctly. The key is to select the highest CRI options (CRI>98) to ensure artworks are displayed with complete color fidelity. The range of precise beam angles, especially the 15° optic, allows curators to frame paintings or sculptures perfectly with minimal light spill. Furthermore, modern LED chips from brands like Citizen and Luminus produce negligible UV and IR radiation, helping to preserve sensitive artifacts. Dimming controls allow for precise intensity adjustments to meet conservation standards.

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

Installation is straightforward for qualified electricians. The D115 Series requires a rectangular cutout of 95x190mm and is secured with spring clips. The fixture connects to an external driver, which can be placed in the ceiling void for better thermal management and serviceability. We offer a comprehensive range of control options to integrate with any building management system. This includes wired protocols like DALI-2 and 0-10V for robust, addressable control, as well as simple TRIAC dimming. For modern smart building projects, we support wireless controls including Casambi (BLE) and ZigBee. Full compliance with CE, RoHS, and ErP directives ensures the product is ready for specification in the European market, while our ISO9001 certified manufacturing process guarantees consistent quality.

Customisation, MOQ and lead time

As a dedicated manufacturer, we specialize in tailoring products to project needs. Beyond our standard matt white and matt black finishes, we can provide custom RAL color powder coating to match any interior design palette. We can also pre-configure fixtures with specific drivers and connectors to streamline on-site installation. The standard Minimum Order Quantity (MOQ) for this series is 100 units. For typical orders, our production lead time is approximately 15-20 working days from confirmation, with shipping arranged to your project location in the EU, US, or Middle East.

Frequently Asked Questions

Q: What is the typical lumen output for the D115 2x15W model?

A: The total output depends on the selected CCT and CRI. With an efficacy of 100-130 lm/W, the 30W fixture (2x15W) delivers a total of 3000 to 3900 lumens. For example, a 4000K CRI90+ version will typically be around 120 lm/W, providing approximately 3600 lumens. We provide exact photometric data for your specific configuration.

Q: Can each of the two heads be aimed independently?

A: Absolutely. This is the primary feature of the design. Each lamp head is mounted on a gimbal that allows for up to 30 degrees of vertical tilt and 355 degrees of horizontal rotation. This enables complete independent aiming, allowing you to direct light precisely where it is needed without compromise.

Q: Are there other power options available in this dual-head series?

A: Yes, the D115 (2x15W) is part of a larger family. For lower ceilings or less intensive applications, we offer the D90 Series at 2x10W. For higher ceilings or where more punch is needed, we have the D140 Series at 2x20W and the D160 Series at 2x30W. This range ensures a consistent aesthetic with scalable output.

Q: What is the warranty and expected lifetime of the fixture?

A: The Double Head Adjustable Downlight series comes with a comprehensive 5-year warranty covering the LED module and the driver. The fixtures are engineered for longevity, with a rated lifetime of L80B10 at over 50,000 hours, ensuring minimal light depreciation and maintenance costs over the lifespan of your commercial installation.
