X5 SMD Series D190 LED Downlight 20-30W Factory

What is the X5 SMD Series D190 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 X5 SMD Series D190 LED Downlight, our versatile, high-efficacy solution for commercial general lighting applications. Engineered for performance and reliability, this 25W to 30W recessed luminaire is designed for contractors and specifiers serving the European, US, and Middle Eastern markets. With a standard cutout size of Ø165mm, it serves as an ideal replacement for legacy CFL fixtures or as the primary illuminant in new construction projects. The X5 D190 features a wide 120° beam angle from its polycarbonate diffuser, delivering smooth, uniform light distribution perfect for ambient illumination. Its robust ADC12 die-cast aluminum construction ensures superior thermal management, guaranteeing a long operational life backed by a 5-year warranty. This series is built for customization, offering an extensive range of CCTs, high-CRI options, and compatibility with leading driver brands and control systems.

Which spaces is it designed for?

The X5 D190 excels in providing high-quality ambient light across large, open areas. Its design priorities are efficiency, uniformity, and reliability, making it a workhorse for commercial fit-outs where functional illumination is key. It is not intended for accent or task lighting where narrow, focused beams are required, but rather as the foundational layer of a lighting scheme.

How does the X5 D190 fit into general commercial lighting plans?

For a lighting designer or electrical contractor in the US or Europe, the X5 D190 is specified to achieve target illuminance levels of 300 to 500 lux for general circulation and activity. With its high efficacy of up to 130 lm/W and a wide 120° beam, fewer fixtures are needed to light a space compared to older technologies or less efficient products. This reduces both the initial capital expenditure and long-term energy costs. For a typical office corridor or hotel lobby, spacing the 30W version at 2.5 to 3-meter intervals can create a bright, welcoming environment that meets code and enhances occupant comfort.

What are the best application environments for a wide-beam downlight?

The X5 D190 is ideally suited for spaces that do not require low-glare (UGR<19) consideration for focused computer work. Its primary applications include:

• Retail: General floor lighting in supermarkets, department stores, and showrooms where broad, even coverage is needed.
• Hospitality: Lobbies, corridors, back-of-house areas, and conference rooms in hotels and restaurants.
• Corporate/Office: Corridors, break rooms, cafeterias, and open-plan reception areas. It is not recommended for desking areas.
• Education & Healthcare: Hallways, libraries, and waiting rooms in schools and hospitals.

Can this downlight support human-centric lighting specifications?

Yes. By specifying the Tunable White (TW) version of the X5 D190, designers can create human-centric lighting (HCL) systems. When paired with a DALI-2 DT8 control system, the luminaire's color temperature can be adjusted dynamically, typically from a warm 2700K to a cool 6500K. This allows the lighting to mimic the natural progression of daylight, which can help regulate circadian rhythms, improve alertness in the morning, and promote relaxation later in the day in office and school environments.

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

Installation is streamlined for professional contractors. The luminaire requires a standard Ø165mm ceiling cutout and has a shallow height of just 86mm, making it suitable for plenums with limited space. Secure installation is achieved via two robust, spring-loaded clips. Electrical connection is made to a remote driver, which can be placed adjacent to the fixture.

We offer a full suite of control options to integrate into any building management system:

• DALI-2: For addressable, digital control in modern smart buildings, offering granular dimming, scene-setting, and energy monitoring.
• 0-10V / 1-10V: A robust and widely used analog dimming protocol for simple, reliable dimming control.
• TRIAC (Phase-cut): For retrofitting into existing circuits with leading-edge or trailing-edge wall dimmers.
• Wireless: Options like Casambi (BLE) and ZigBee are available for projects where running new control wiring is not feasible.

All driver and luminaire combinations are CE marked and RoHS compliant, and our products meet European ErP directives for energy efficiency, ensuring a smooth specification and inspection process.

Customisation, MOQ and lead time

As a direct manufacturer, we provide extensive OEM and ODM customization services. Beyond the standard specifications, we can tailor the X5 D190 to your exact project needs. Customizations include specific CCTs (e.g., 3200K), alternative LED chips (Samsung, Bridgelux), or custom housing finishes in any RAL color to match brand aesthetics or interior design palettes. Branded packaging and product labeling are also available.

• Minimum Order Quantity (MOQ): The standard MOQ for the X5 series is 100 units. For fully custom RAL colors or non-standard components, an MOQ of 500 units may apply.
• Lead Time: Our typical production lead time is 15-25 working days from order confirmation to dispatch from our factory in China. Air and sea freight options are available for delivery to the EU, USA, and the Middle East.

Frequently Asked Questions

Q: What is the standard warranty on the X5 D190 and what does it cover?

A: The X5 D190 comes with a comprehensive 5-year warranty. This covers failure of the LED module and driver, as well as performance degradation beyond specified limits, such as lumen depreciation exceeding 30% (L70) within the warranty period. It guarantees peace of mind for commercial project specifiers and facility managers, ensuring a reliable and long-lasting installation.

Q: Can I get this downlight in a custom RAL color finish?

A: Yes, custom finishes are a key part of our service. While we stock Matt White (RAL9016) and Matt Black (RAL9005), we can produce the fixture in any custom RAL color. This service is typically available for project orders with a minimum quantity of 500 units to allow for a dedicated powder-coating batch. Please provide the RAL code for a quotation.

Q: How is thermal management handled in the X5 series to ensure longevity?

A: The luminaire body is constructed from ADC12 die-cast aluminum, which functions as a highly effective passive heatsink. The deep fin design maximizes the surface area for heat dissipation into the ceiling plenum. This engineering ensures the LED junction temperature (Tj) is maintained below 85°C in typical operating conditions, which is crucial for achieving the 50,000-hour rated lifespan.

Q: What is the SDCM value for the X5 downlights?

A: We guarantee a standard color consistency of less than 3-step MacAdam ellipses (SDCM <3) across all units in a given order. This tight binning ensures that there are no visible differences in the color of the white light from one luminaire to the next, providing a high-quality, uniform appearance that is essential for professional architectural lighting.
