X5 COB Series D190 LED Downlight 20-30W Global Supplier

What is the X5 COB Series D190 LED Downlight 20-30W and where is it specified?

At XHLWX (led-project-light.com), a Custom Indoor LED Lighting Manufacturer based in China, we present the X5 COB D190 Series LED Downlight, a cornerstone of our architectural lighting portfolio for the EU, US, and Middle East markets. Engineered for commercial spaces that demand high performance and visual comfort, this 25W to 30W luminaire provides powerful, high-quality illumination from a discreet source. With a substantial Ø190mm trim and requiring a Ø165mm cutout, it's designed for general and ambient lighting in retail stores, corporate offices, hotels, and educational facilities. Its high-efficacy output of 100-130 lm/W makes it an ideal one-for-one replacement for legacy 2x26W PLC downlights, offering over 60% in energy savings and vastly superior light quality.

Which spaces is it designed for?

The X5 D190 is a versatile workhorse luminaire intended for professional specification in new construction and renovation projects. Its balance of high output, visual comfort, and aesthetic consistency makes it a preferred choice for specifiers and lighting designers in Europe and North America who require a reliable, certified, and customisable lighting solution.

How can this downlight achieve both high output and visual comfort in an office environment?

Achieving a productive and comfortable office environment requires lighting that is both bright and low-glare. The X5 D190 excels here by combining a powerful COB LED light source with precision-engineered optics. The LED is deeply recessed within the fitting, shielding it from direct view. The faceted reflector then shapes the light into a clean, 60° beam, minimizing stray light that causes glare on screens and surfaces. This design allows for the achievement of a Unified Glare Rating (UGR) of less than 19, compliant with the European standard EN 12464-1 for office lighting, while delivering an average illuminance of 300-500 lux on workstations.

What makes the X5 D190 suitable for high-end retail and hospitality projects?

In retail and hospitality, lighting's primary role is to enhance the customer experience by rendering products and interiors attractively. The X5 D190's key advantage is its exceptional color quality. We offer configurations with CRI values up to Ra 98, ensuring that fabrics, fresh produce, and skin tones appear natural and vibrant. For even more nuanced color evaluation, we provide TM-30 reports, with fidelity (Rf) scores exceeding 90. Furthermore, our Dim-to-Warm (DTW) option allows hotel restaurants or bars to transition from a bright 3000K to a cozy 1800K candlelight glow as the fixture is dimmed, creating the perfect atmosphere.

Can the D190 be integrated into a larger, multi-size downlight scheme?

The X5 D190 is not a standalone product but a key member of the X5 COB family. This series offers a consistent design aesthetic across four different sizes: the compact D110 (10W, Ø90mm cutout), the mid-size D145 (15W, Ø125mm cutout), this D190 model (25-30W, Ø165mm cutout), and the powerful D230 (35W, Ø200mm cutout). This family approach allows a lighting designer to maintain visual continuity throughout a project, using the D190 for general lighting in large open areas and the smaller D110/D145 for corridors, restrooms, or accent lighting, all while using the same high-quality light engine and finishes.

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

Installation of the X5 D190 is streamlined for professional contractors. The unit is designed for a Ø165mm ceiling cutout and secured with robust, pre-installed spring clips, making it suitable for both plasterboard and suspended grid ceilings. The luminaire is powered by a remote driver connected via a simple plug-and-play connector, allowing for easy maintenance and driver access from above the ceiling.

For control systems, we offer a comprehensive range of options compatible with global building management systems. This includes wired protocols like DALI-2 for addressable control, 0-10V analog dimming for simple scene-setting, and phase-cut (TRIAC) dimming for retrofit projects. We also fully support wireless control via Casambi (Bluetooth Low Energy) and Zigbee, enabling app-based control and integration into modern smart building ecosystems.

Compliance is guaranteed for European and international projects. The fixture is CE marked, confirming it meets EU safety, health, and environmental protection requirements. It is also RoHS compliant, restricting the use of hazardous materials. Adherence to the ErP directive ensures it meets stringent energy efficiency targets. Our manufacturing facility is ISO9001 certified, ensuring consistent quality control from order to delivery.

Customisation, MOQ and lead time

As a direct manufacturer, we offer extensive customisation. Beyond the standard Matt White (RAL9016) and Matt Black (RAL9005) finishes, we can provide any custom RAL color for projects with a Minimum Order Quantity (MOQ) of 200 units. We can also source specific CCTs, CRI bins, or driver brands to match a project's exact lighting specification. Our standard MOQ for catalog configurations is 50 units.

Our typical production lead time is 15-25 working days from order confirmation. Customised orders may require additional time based on component sourcing and finishing. We work closely with our logistics partners to ensure reliable shipping to Europe, the USA, and the Middle East.

Frequently Asked Questions

Q: What is the standard warranty, and what components does it cover?

A: We provide a comprehensive 5-year warranty on the entire X5 D190 luminaire. This covers the Citizen, Bridgelux, or CREE COB LED module against premature failure and lumen depreciation beyond L80B10, as well as the paired Tridonic, Osram, or Philips driver. This ensures long-term performance and peace of mind for your project investment.

Q: Can I get photometric data to use in my lighting design software?

A: Absolutely. We provide complete photometric files in both IES and LDT formats for every configuration of the X5 D190. These files are essential for accurate lighting calculations and visualizations in software like DIALux or AGi32, allowing you to model illuminance levels and uniformity for your specific space before installation.

Q: What is the maximum wattage and lumen output for this specific D190 model?

A: The X5 D190 model is available in 25W and 30W versions. At 30W, using a high-efficiency COB chip at 4000K, it can achieve a luminous flux of up to 3900 lumens. This high output makes it an excellent energy-efficient replacement for older 2x26W compact fluorescent downlights, delivering more light for less power.

Q: Are custom housing colors available for large projects?

A: Yes, customisation is a core part of our service. While matt white (RAL9016) and matt black (RAL9005) are standard, we can produce the D190 downlight in any custom RAL color for orders exceeding 200 units. This allows you to perfectly match the luminaire trim to your interior design scheme for a seamless, integrated look.
