DC48V Low Voltage LED Linear Light Diffuser Version 10-30w

What is the DC48V Low Voltage LED Linear Light Diffuser Version and where is it specified?

At XHLWX (led-project-light.com), a Custom Indoor LED Lighting Manufacturer based in China, we present the DC48V Low Voltage LED Linear Light Diffuser Version, a core component of our versatile 48V magnetic track lighting system. This luminaire is engineered to deliver seamless, homogeneous general illumination, serving as the foundational ambient light layer in sophisticated architectural spaces. Unlike spotlights that create focused accents, the diffuser module provides a broad, soft wash of light, enhancing visual comfort and creating a sense of openness. Available in 10W, 20W, and 30W configurations corresponding to lengths of 300mm, 600mm, and 900mm, it allows for flexible and scalable designs. The housing is crafted from high-grade ADC12 die-cast aluminum for superior thermal management and durability, finished in a minimalist matt white or black to integrate discreetly into any ceiling design. It is the preferred choice for specifiers seeking high-performance, low-glare general lighting within a flexible, low-voltage track infrastructure.

Which spaces is it designed for?

The modularity and high-quality light output of the DC48V Linear Diffuser make it suitable for a wide range of commercial and hospitality applications where both aesthetics and visual performance are paramount.

How can this linear module improve visual comfort in modern offices?

In office environments, achieving optimal visual conditions is critical for productivity and well-being. This linear diffuser is engineered to help lighting designers meet the stringent requirements of standards like EN 12464-1. When integrated into a ceiling grid, its wide 120° distribution provides excellent ambient illumination, capable of delivering a uniform 300-500 lux on task surfaces. The key advantage is its low glare output, which can achieve a UGR<19, minimizing eye strain for employees working on screens. Paired with a Tunable White (TW) option and DALI control, it can support human-centric lighting strategies, mimicking natural daylight cycles to enhance alertness and comfort.

How does it enhance product presentation in retail and gallery settings?

For high-end retail, showrooms, and galleries, color accuracy is non-negotiable. With a standard CRI of >90 and options for >95, this luminaire renders textiles, cosmetics, and artwork with exceptional fidelity. Unlike multiple spotlights which can create competing highlights and harsh shadows, the linear diffuser provides a soft, foundational layer of light. This reduces specular reflections on glass displays and shiny merchandise, creating a more sophisticated and pleasant shopping experience. Its minimalist form factor ensures the focus remains on the products, not the light source, complementing modern retail architecture.

What is the best way to use it for hospitality wayfinding and ambient lighting?

In hotels, reception areas, and lounges, creating a welcoming atmosphere is key. The DC48V Linear Diffuser excels at this, particularly with warm color temperatures of 2700K or 3000K. In corridors, it can be used to create continuous, uninterrupted lines of light that serve as an intuitive wayfinding element, guiding guests seamlessly through the space. When integrated with control systems like DALI-2 or Casambi, staff can easily trigger pre-programmed scenes—brighter and more energetic during daytime check-in, softer and more intimate in the evening—enhancing the overall guest experience.

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

Installation is a simple, tool-free process. The module's adapter clicks into the DC48V magnetic track, establishing both a secure mechanical and electrical connection. This flexibility allows fixtures to be easily repositioned, added, or removed as spatial requirements change.

We offer a comprehensive range of control options to meet any project specification:

• DALI-2: The gold standard for commercial lighting control, offering individual addressing, group control, status feedback, and guaranteed interoperability. Ideal for integration into building management systems (BMS).
• Casambi (BLE): A powerful wireless mesh solution controlled via Bluetooth Low Energy. Perfect for projects where running new control wiring is impractical, offering intuitive app-based control, scene setting, and scheduling.
• 0-10V: A robust and widely understood analog dimming protocol for simple, reliable intensity control.

All versions are fully compliant with European Union directives, including CE for electrical safety (LVD) and electromagnetic compatibility (EMC), RoHS for hazardous substances, and ErP for energy efficiency. Complete IES and LDT photometric files are available for import into DIALux, Relux, and other lighting design software, enabling precise project planning and compliance verification.

Customisation, MOQ and lead time

As a manufacturer, we offer extensive customisation to meet specific project needs. While Matt White (RAL9016) and Matt Black (RAL9005) are standard stock finishes, we can produce the housing in any custom RAL color for projects with a Minimum Order Quantity (MOQ) of 100 units. Special requests for specific CCTs, CRI >95, or specific Tunable White ranges can also be accommodated.

The standard MOQ for this product series is 50 units. Standard orders typically have a production lead time of 15-25 working days from drawing approval to dispatch from our facility. Customised orders may require additional time for material sourcing and production setup.

Frequently Asked Questions

Q: What is the primary advantage of the diffuser version over a track spotlight?

A: The diffuser version provides wide, uniform general illumination with a 120° beam angle, ideal for ambient lighting and reducing shadows. Unlike spotlights which create focused accent light, this linear module is designed for visual comfort and delivering even lux levels across a space, often achieving a UGR well below 19.

Q: Can I mix this 600mm linear module with 150mm spotlights on the same track?

A: Absolutely. The DC48V magnetic track system is fully modular. You can combine linear modules of 300mm, 600mm, and 900mm with any of our spotlight or wallwasher modules. Simply ensure the total wattage of all fixtures does not exceed the capacity of the 48V power supply, which typically ranges from 100W to 300W.

Q: Is there a maximum length for a single continuous track powered by one driver?

A: To avoid significant voltage drop and ensure consistent light output, we recommend a maximum continuous track length of 5 meters (approx. 16.4 feet) per single power feed. For longer runs, the track must be powered from the center or with multiple power feeds. Our technical team can provide a layout plan for your specific project.

Q: Does this linear light support human-centric lighting applications?

A: Yes, we offer a Tunable White (TW) version specifically for human-centric lighting. This option allows the color temperature to be dynamically adjusted, typically from a warm 2700K to a cool 6500K. This feature, controlled via DALI DT8, can help synchronize lighting with natural daylight patterns to improve occupant well-being.
