X7-D140 Ultra Slim LED Downlight 12-15W Large Quantity Supplier

What is the X7-D140 Ultra Slim LED Downlight and where is it specified?

At XHLWX (led-project-light.com), a Custom Indoor LED Lighting Manufacturer based in China, we engineer solutions for modern architectural challenges. The X7-D140 is a prime example: an ultra-slim, high-performance LED downlight designed for commercial, hospitality, and large-scale residential projects with minimal ceiling void space. With a recessed depth of only 36mm, this 12W/15W luminaire fits into the tightest plenums without compromising on light quality or output. It requires a standard Ø125mm cutout for its Ø140mm trim, ensuring a clean and unobtrusive aesthetic. The X7-D140 is part of a versatile family that includes 5W (Ø106mm), 20W (Ø180mm), and 30W (Ø230mm) versions, allowing for a consistent design language across spaces with varying ceiling heights and illumination requirements. Its performance-driven design and large-quantity manufacturing capacity make it a staple for contractors and specifiers in the EU and US markets.

Which spaces is it designed for?

The X7-D140's combination of a very slim profile, wide beam distribution, and extensive customisation options makes it a versatile choice for ambient lighting in various commercial applications. Its value is most apparent in large-volume projects where consistency, reliability, and installation speed are paramount.

How can the X7-D140 be used for general lighting in hotel corridors and guest rooms?

In hospitality settings, ceiling void space is often at a premium due to extensive mechanical and electrical services. The X7-D140's 36mm depth is a significant advantage. Its wide 120° beam allows for greater spacing between fixtures while still achieving the required 150-200 lux levels in corridors, reducing both initial cost and installation time. For guest rooms, specifying a high CRI (>90) at a warm CCT of 2700K or 3000K creates a comfortable, high-quality environment. Integration with TRIAC or DALI dimming systems provides guests with lighting control and helps properties meet energy efficiency goals.

Is this downlight suitable for modern office and breakout areas?

For general ambient lighting in circulation zones, reception areas, and employee breakout spaces, the X7-D140 excels. Its minimalist, trimless appearance integrates seamlessly into modern office interiors. A neutral 4000K CCT with CRI>90 promotes alertness and accurate color perception. While its wide beam is not optimized for UGR<19 task areas with computer screens, it provides excellent, uniform base illumination. It can be integrated into a building-wide DALI control system, allowing for daylight harvesting and scene-setting in multi-purpose zones, contributing to WELL and BREEAM building standards.

What makes the X7-D140 a good choice for high-volume residential or retail projects?

The key benefits for large-scale developments are cost-efficiency, reliability, and speed. The X7-D140 is designed for mass production, making it a cost-effective solution for apartment buildings or retail chain rollouts. The robust ADC12 aluminium construction and 5-year warranty, backed by Samsung LEDs, minimize future maintenance liabilities. The ultra-slim profile is particularly useful in multi-story buildings or complex retail fit-outs, where every centimeter of ceiling height counts. Standard Matt White and Matt Black finishes cater to 90% of interior design schemes, while custom RAL colors are available for branded environments.

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

Installation of the X7-D140 is streamlined for professional contractors. The luminaire fits a Ø125mm cutout and is secured by two durable spring clips. The external driver architecture simplifies mains connection and allows for easier replacement or maintenance without removing the entire fixture. We offer a comprehensive range of control protocols to meet any project requirement, from simple TRIAC phase-cut dimming for residential projects to advanced digital control. Available options include DALI-2, 0-10V/1-10V, and wireless systems like Casambi (Bluetooth Low Energy) and ZigBee, enabling full integration into smart building ecosystems. The product is fully compliant with EU regulations, holding CE (LVD/EMC), RoHS, and ErP certifications, ensuring a smooth specification and inspection process.

Customisation, MOQ and lead time

As a direct manufacturer, we offer extensive customisation. Beyond the standard CCT and CRI options, we can supply the X7-D140 with specialized outputs like Tunable White (TW), Dim-to-Warm (DTW), and RGBW for dynamic lighting applications. While our standard finishes are Matt White and Matt Black, we can provide custom powder coating to any RAL colour for projects with a minimum order of 500 units. You can also specify your preferred driver brand to maintain consistency across a project. Our Minimum Order Quantity (MOQ) for the X7-D140 series is 200 units. The standard production lead time is approximately 25-35 days from order confirmation, depending on component stock and the scale of customisation.

Frequently Asked Questions

Q: What is the standard warranty and expected lifetime of the X7-D140?

A: The X7-D140 comes with a comprehensive 5-year manufacturer's warranty covering the LED module and driver. The Samsung LED chips are rated for a service life of L80B10 at 50,000 hours, which means that after 50,000 hours of operation, 90% of the fixtures will still maintain at least 80% of their initial lumen output.

Q: Can I get this downlight in a custom colour?

A: Yes, customisation is one of our core services for project clients. For orders exceeding 500 units, we can finish the downlight trim in any specified RAL colour to perfectly match your interior design palette. Standard finishes are Matt White (RAL9016) and Matt Black (RAL9005). Please allow an additional 7-10 days for custom colour orders.

Q: Is the X7-D140 suitable for bathroom installations?

A: The standard X7-D140 luminaire is IP20 rated, which certifies it for use in dry, indoor locations only. It is not protected against moisture and is therefore not suitable for any bathroom zones. For applications requiring moisture resistance, such as bathroom Zone 2, we recommend specifying a product with a minimum IP44 rating from our portfolio.

Q: What is the maximum lumen output of the 15W version?

A: The 15W version of the X7-D140 is highly efficient, capable of delivering up to 130 lumens per watt (lm/W). This results in a maximum fixture light output of approximately 1950 lumens. This peak output is typically achieved with a 4000K or 5000K CCT and a standard CRI of 80. Higher CRI or warmer CCT selections will have a slightly lower lumen package.
