Professional X5 SMD Series D230 LED Downlight 30-45W

What is the Professional X5 SMD Series D230 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 Professional X5 SMD Series D230 LED Downlight, the flagship model in our high-performance general lighting range. This luminaire is engineered for commercial, retail, and public spaces that demand high luminous output, exceptional efficiency, and reliable performance. With a powerful 30W to 45W output range and a substantial Ø230mm form factor designed for a Ø200mm cutout, the X5 D230 is the definitive solution for projects with high ceilings or ambitious illuminance targets. Its core design features a robust ADC12 die-cast aluminium heatsink for superior thermal management and a high-transmission polycarbonate diffuser that delivers a wide, uniform 120° beam angle. This makes it ideal for replacing legacy fluorescent or metal halide fixtures, offering significant energy savings and superior light quality in a modern, minimalist package. It is primarily specified for large-scale interior projects across Europe, the US, and the Middle East, including shopping malls, airports, hotel lobbies, and open-plan offices.

Photometric and electrical specification

The X5 D230 series is built to meet stringent international standards, offering specifiers complete control over performance parameters. Full IES and LDT photometric files are available for integration into lighting design software like DIALux.

Which spaces is it designed for?

As a versatile, high-output luminaire, the X5 D230 is specified by contractors and designers for a variety of demanding commercial environments.

How can this downlight provide effective general lighting in a large office or retail space?

The key advantages for large open areas are high lumen output and broad distribution. The 45W version can produce over 5,800 lumens, while the 120° beam angle ensures wide, overlapping pools of light. This allows for a greater spacing-to-height ratio, reducing the total number of fixtures required to achieve a target illuminance, such as 500 lux for an office or 750 lux for a high-end retail floor. Using our IES files in a DIALux simulation, a lighting designer can easily model a grid layout to guarantee uniformity and meet code requirements like those in EN 12464-1, minimizing both initial capital cost and long-term energy consumption.

What makes the X5 D230 suitable for high-ceiling applications like atriums or hotel lobbies?

For spaces with ceiling heights between 4 and 7 meters, raw power and thermal stability are critical. The X5 D230's 40W and 45W options deliver the necessary punch to push functional light levels to the floor. The oversized ADC12 die-cast aluminium housing acts as a highly efficient passive heatsink, drawing heat away from the Epistar SMD board and ensuring the luminaire maintains its performance over a 50,000-hour L80B10 lifespan. Paired with reliable drivers from brands like Tridonic or Osram, this downlight offers a fit-and-forget solution for facility managers, backed by a 5-year warranty.

Can the light quality be specified for color-critical tasks in showrooms or educational settings?

Absolutely. While the standard CRI>80 is sufficient for general use, we offer high-density LED boards with CRI>90, CRI>95, and even CRI>98 for applications where color fidelity is paramount. For a premium car showroom, a fashion boutique, or a museum space, specifying the CRI>95 option ensures that colors appear vibrant and true. We provide full TM-30-20 reports for these options, often showing an Rf (fidelity index) above 95 and an Rg (gamut index) near 100. Combined with a tight color consistency of <3 SDCM, an entire installation will have a uniform, high-quality appearance without any perceptible color shift between fixtures.

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

Installation of the X5 D230 is streamlined for professional contractors. The fixture requires a circular Ø200mm ceiling cutout and is secured by two robust, spring-loaded clips, ensuring a flush and stable fit in plasterboard or suspended ceilings. The external driver connects via a simple plug-and-play connector, allowing for easy maintenance or replacement without removing the luminaire itself.

Control flexibility is central to the X5 series. We support a full range of protocols:

• DALI-2: For addressable, digitally controlled lighting systems in smart buildings, offering detailed diagnostics and interoperability.
• 0-10V/1-10V: A reliable analog dimming standard common in North American and European commercial projects.
• TRIAC (Phase-cut): For cost-effective dimming using standard leading/trailing edge wall dimmers.
• Wireless: Integration with Casambi (Bluetooth Low Energy) or ZigBee mesh networks for app-based control and advanced scene-setting without new control wiring.

All variants are fully compliant with European market standards, bearing the CE mark (covering LVD and EMC directives), RoHS certification for hazardous substance restriction, and meeting the latest ErP ecodesign requirements for energy efficiency. Our factory's ISO9001:2015 certification underpins our commitment to consistent production quality.

Customisation, MOQ and lead time

We specialize in tailoring products to meet precise project needs. Customisation for the X5 D230 series includes:

• RAL Finish: Beyond our standard Matt White (RAL9016) and Matt Black (RAL9005), we can provide a custom powder coat finish to any RAL color for a minimum order quantity (MOQ) of 200 units.
• Light Engine: Specify any CCT from 2700K to 6500K, a CRI level up to 98 Ra, or advanced outputs like Tunable White, Dim-to-Warm, or RGBW.
• Driver & Dimming: Choose your preferred driver brand and control protocol to match the building management system.

The standard MOQ for this series is 100 units. Our typical production lead time for standard configurations is 20-25 working days from order confirmation. For custom RAL finishes or non-standard LED specifications, please allow for a lead time of 30-35 working days.

Frequently Asked Questions

Q: What is the luminous efficacy of the 40W, 4000K, CRI90+ version?

A: The 40W version specified at 4000K with CRI90+ typically achieves a luminous efficacy of around 115 lm/W. This results in a total output of approximately 4600 lumens. Efficacy can vary slightly based on the chosen driver and specific CCT, but we guarantee performance above 100 lm/W for all CRI90+ models.

Q: Can I get this downlight with a lower Unified Glare Rating (UGR)?

A: While the standard 120° diffuser provides a UGR suitable for general circulation areas, achieving UGR<19 for office tasks requires careful planning. We can supply this fixture with optional low-glare micro-prismatic diffusers or black anti-glare reflectors on request. These accessories can reduce the UGR to below 19 in DIALux simulations for standard office layouts with ceiling heights up to 3 meters.

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

A: We provide a comprehensive 5-year warranty on the complete X5 D230 LED Downlight luminaire, including the LED module and the external driver. This covers defects in materials and workmanship, ensuring a lumen maintenance of L80B10 at 50,000 hours under normal operating conditions. The warranty is valid for installations within the specified ambient temperature range of -20°C to +45°C.

Q: What are the minimum order quantity and lead time for a custom RAL finish?

A: For custom RAL color finishes, the minimum order quantity (MOQ) is 200 units. The production lead time for custom orders is typically 30-35 working days, which is slightly longer than the 20-25 day lead time for our standard matt white or matt black finishes. This allows for powder coating and proper curing to ensure a durable finish.
