X5 COB Series D230 LED Downlight 30-45W Bulk Supplier

What is the X5 COB Series D230 LED Downlight 30-45W and where is it specified?

At XHLWX (led-project-light.com), a Custom Indoor LED Lighting Manufacturer based in China, we present the X5 D230 Series LED Downlight, our premier solution for high-ceiling commercial and public spaces. As the largest and most powerful fixture in the X5 family, the D230 is engineered for applications demanding high lumen output and broad, uniform illumination from a recessed source. Specified for new builds and retrofits with a Ø200mm cutout, this 30-45W downlight serves as a direct, energy-efficient replacement for legacy 70W metal halide or twin 32W compact fluorescent (CFL) fixtures. Its wide 120° beam angle and deeply recessed, diffused light source are designed to create comfortable, well-lit environments in atriums, retail stores, transport hubs, and large office lobbies across our primary export markets in the EU, USA, and the Middle East.

Photometric and electrical specification

The X5 D230 is built to meet the rigorous performance and compliance standards required by international specifiers. We provide complete IES and LDT photometric files for use in DIALux or other lighting design software to ensure your project's lighting calculations are precise and code-compliant. The table below outlines the key technical specifications.

Which spaces is it designed for?

The high output and large aperture of the X5 D230 make it an exceptionally versatile luminaire for general illumination from ceiling heights ranging from 3.5 to 7 meters. Its application is primarily in commercial, public, and institutional settings where powerful, reliable, and efficient lighting is a key operational requirement.

How can this downlight provide uniform general lighting in large retail stores or atriums?

For large, open-plan spaces like shopping mall atriums, airport terminals, or 'big box' retail stores, the D230's performance is ideal. The combination of high lumen output (up to 5,850 lumens for the 45W version) and a very wide 120° beam angle allows for a wider spacing between fixtures. For a US-based contractor or a European electrical planner, this means fewer installation points, reduced labor costs, and lower overall energy consumption to achieve a target illuminance of 300-500 lux on the floor. The recessed diffuser also minimizes direct glare for a comfortable shopping experience.

Is the D230 suitable for office and school circulation areas?

Absolutely. In modern office buildings and educational facilities, common areas like wide corridors, reception areas, and canteens require bright, welcoming, and uniform light. The X5 D230 meets these needs perfectly. Using the 4000K CCT option with CRI>80 provides a neutral, energizing light that adheres to EN 12464-1 standards for circulation spaces. While its UGR rating makes it unsuitable for direct placement over VDU workstations, it serves as the perfect ambient lighting core when paired with task lighting.

What makes this a good choice for hotel lobbies and conference centers?

In hospitality, atmosphere is paramount. The D230 can be specified with warm CCTs (2700K or 3000K) and high CRI (90+ or 95+) to render interior finishes and skin tones richly and accurately. Paired with a DALI-2 driver, lighting in a conference center or ballroom can be seamlessly dimmed down to 1% for presentations or events, then brought back to full brightness for cleaning or setup. The large 230mm diameter creates a bold architectural presence in high-ceilinged lobbies, making the lighting an integral part of the design statement.

Installation, control and compliance

Engineered for straightforward installation by electrical contractors, the X5 D230 fits into a standard Ø200mm ceiling cutout and is secured by two robust spring-loaded clips. The luminaire is powered by an external remote driver, which is connected via a simple plug-and-play connector, allowing for easy maintenance and replacement without removing the entire fixture. This separation also improves thermal management, extending the life of both the driver and the LEDs to over 50,000 hours (L80B10).

Control flexibility is central to the X5 series. We offer drivers compatible with all major protocols:

• DALI-2: For addressable, interoperable control in smart buildings, certified for the European market.
• 0-10V / 1-10V: A reliable and cost-effective analog dimming solution popular in the US.
• TRIAC (Phase-cut): For simple dimming in retrofit projects using existing wiring.
• Wireless: Options including Casambi (Bluetooth Low Energy) and ZigBee are available for projects where running new control wiring is impractical.

Full compliance with CE (LVD/EMC), RoHS, and ErP directives ensures the product is ready for specification and trouble-free import into any EU member state.

Customisation, MOQ and lead time

As a manufacturer, we offer extensive customisation to meet specific project requirements. Beyond standard CCT and CRI options, we can supply the X5 D230 with Tunable White (2700K-6500K), Dim-to-Warm (3000K-1800K), and RGBW LED arrays. While our standard finishes are Matt White and Matt Black, any custom RAL color can be applied to the bezel for orders exceeding 200 units.

Our standard Minimum Order Quantity (MOQ) for the X5 D230 series is 100 units. This allows us to maintain competitive pricing and efficient production scheduling.

Typical production lead time for standard configurations is 20-25 working days after drawing approval. Sea freight to major European or US ports typically takes an additional 30-40 days. Air freight options are available for urgent project deadlines.

Frequently Asked Questions

Q: What is the total lumen output for the 45W version?

A: The 45W X5 D230 downlight delivers a system lumen output between 4500 to 5850 lumens, depending on the selected CCT and CRI. With a high efficacy of up to 130 lm/W, it provides powerful illumination suitable for ceiling heights of 4 to 7 meters. This makes it an ideal energy-saving replacement for 70W metal halide fixtures.

Q: Are photometric files available for lighting design software?

A: Yes, comprehensive photometric data is available for all variants. We provide IES and LDT files compatible with standard lighting design software, including DIALux and Relux. This allows electrical engineers and lighting designers to accurately model illuminance levels and uniformity for their projects, ensuring compliance with local codes in Europe and the US before specification.

Q: What is the warranty period and what does it cover?

A: The X5 D230 series comes with a comprehensive 5-year warranty. This warranty covers the entire luminaire, including the ADC12 aluminum housing, finish, and the LED array against premature failure (L80B10 at 50,000 hours). It also covers the separate driver from brands like Tridonic or Osram, ensuring long-term reliability for facility managers and building owners.

Q: Can this fixture be used in damp locations like a covered outdoor area?

A: No, this downlight has an IP20 rating, which means it is protected against solid objects larger than 12.5mm but has no protection against moisture. It is designed exclusively for dry indoor environments such as offices, retail spaces, and hotel lobbies. For damp or wet locations, please consult our range of IP44 or IP65 rated downlights.
