Grille LED Downlight D330 Series 2*20-2*30W Supplier

What is the D330 Series Grille 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 D330 Series Grille LED Downlight, a premier architectural lighting solution designed for discerning specifiers and contractors in the EU, US, and Middle East. This dual-head recessed luminaire combines powerful, efficient performance with a sophisticated, low-glare aesthetic. Engineered with two individually adjustable light sources, the D330 series delivers a total power output ranging from 40W (2x20W) to 60W (2x30W), making it ideal for applications demanding high-impact accent lighting or functional ambient illumination from a discreet source. The deep-recessed design, coupled with a precision-engineered black baffle, minimizes glare and ensures a Unified Glare Rating (UGR) of less than 19, promoting visual comfort in commercial settings. Constructed from robust ADC12 die-cast aluminum for superior thermal management and durability, the D330 is the definitive choice for high-end retail, corporate headquarters, and hospitality projects where quality and performance are paramount.

Photometric and electrical specification

The D330 Series is engineered to meet rigorous international standards, offering extensive customization to match precise project requirements. Full IES and LDT photometric files are available for integration into DIALux Evo and other lighting design software, ensuring accurate project simulation.

Which spaces is it designed for?

The D330 Series excels in commercial environments where the quality of light directly impacts customer experience, employee productivity, and brand perception. Its dual-head, adjustable design allows a single fixture to perform multiple tasks, such as simultaneously highlighting merchandise on a display and contributing to the general circulation path lighting. For a luxury retail store, a configuration of 3000K, CRI95+ D330s with 24° beams can be used to create dramatic focal points, achieving illuminance levels of over 1500 lux on displays while maintaining comfortable ambient light. In a corporate boardroom, a 4000K, UGR<19 version provides crisp, clean light for video conferencing and task-oriented activities.

How can this fixture achieve low glare in an office or retail environment?

The primary method for achieving its excellent low-glare rating (UGR<19) is its physical design. The LED light sources are deeply recessed within the housing, shielding the high-intensity chip from the normal field of view. This is enhanced by a matt black internal baffle that absorbs stray light and prevents distracting reflections. This design philosophy directly addresses the requirements of standards like EN 12464-1 for lighting of workplaces, ensuring visual comfort for employees and customers, even with powerful outputs of up to 7,800 lumens per fixture.

What are the options for creating dynamic lighting scenes in a hotel or gallery?

For dynamic environments, the D330 Series offers extensive control flexibility. When specified with a DALI Type 8 (DT8) driver, the luminaire can provide Tunable White (TW) or Dim-to-Warm (DTW) functionality, allowing operators to shift the color temperature from a warm, intimate 2700K to a cool, functional 6500K. This is ideal for hospitality spaces that transition from daytime business use to evening social functions. For more theatrical effects in galleries or event spaces, the RGBW version controlled via DMX allows for a full spectrum of color mixing and scene-setting, all managed through a centralized building management system.

Can the beam be adjusted to highlight specific products or architectural features?

Yes, adjustability is a core feature. Each of the two light heads can be individually tilted up to 30° and rotated 355°, providing precise directional control. Furthermore, the beam angle itself is not fixed. The D330 uses an interchangeable lens system, allowing contractors to switch between a tight 15° spot for highlighting small objects, a versatile 24° or 38° beam for accenting artwork and displays, and a wider 60° flood for wall washing or broader ambient lighting. This flexibility allows for on-site refinement of the lighting scheme without replacing the entire fixture.

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

Installation of the D330 Series is straightforward for qualified electrical contractors. The luminaire requires a rectangular ceiling cutout of 320x160mm and is secured by robust, spring-loaded mounting clips suitable for various ceiling thicknesses. All drivers are external and come with plug-and-play connectors for simplified maintenance.

Control system integration is seamless. We offer drivers for all major protocols:

• DALI-2: For certified interoperability in large-scale, intelligent commercial projects with digital dimming, scene recall, and energy monitoring.
• Casambi (BLE): Ideal for wireless, app-based control in retrofits, showrooms, or spaces requiring easy reconfiguration. Each fixture becomes a node in a robust Bluetooth mesh network.
• 0-10V: A reliable and cost-effective analog dimming solution for standard commercial applications.

All configurations are fully compliant with EU regulations, bearing the CE mark (LVD/EMC), RoHS certification for hazardous substance restrictions, and ErP directive compliance for energy efficiency. We provide comprehensive IES and LDT photometric files for all standard configurations to support your lighting design process in DIALux or other professional software.

Frequently Asked Questions

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

A: The D330 Series comes with a comprehensive 5-year warranty. This covers both the LED module and the external driver against manufacturing defects and failure under normal operating conditions. It guarantees the luminaire will maintain at least 80% of its initial lumen output for 50,000 hours of use (L80B10), ensuring long-term performance and peace of mind for your project.

Q: Can I get this fixture with a specific driver brand not listed?

A: Yes, we frequently accommodate customer-specified components for project orders. While our standard offerings include premier brands like Tridonic and Osram, we can source and integrate drivers from nearly any major manufacturer. For projects requiring over 100 units, we can facilitate the procurement and testing of your preferred driver to ensure full compatibility and performance.

Q: How is the color consistency (SDCM) maintained across a large order?

A: We guarantee superior color consistency by using LED chips binned within a 3-step MacAdam ellipse (SDCM < 3). This tight tolerance ensures there is no perceptible color difference between any two fixtures in an installation. For large orders of 200+ units, we secure single-bin chip sourcing from suppliers like Bridgelux and Citizen to maintain this consistency across the entire production run.

Q: What is the typical lumen output for the 60W, CRI90 version?

A: The 60W (2x30W) D330 model configured with a 4000K CCT and a high CRI of 90+ typically delivers a system lumen output of approximately 6,600 lumens. This results in a strong system efficacy of around 110 lm/W. The exact output can vary by about 5-8% depending on the selected beam angle and CCT, with warmer CCTs having slightly lower output.
