D28 Series 18V Magnetic Low Voltage LED Track Light 3W

What is the D28 Series 3W Magnetic Low Voltage LED Track Light and where is it specified?

At XHLWX (led-project-light.com), a Custom Indoor LED Lighting Manufacturer based in China, we engineer architectural lighting solutions for discerning specifiers. The D28 Series 3W Magnetic Low Voltage LED Track Light is our most compact and versatile accent lighting fixture, designed for seamless integration into 48V magnetic track systems. With a miniature profile of just 28mm in diameter and 60mm in length, this 3W spotlight delivers precise, high-quality illumination without visual clutter. Its key feature is the magnetic base, allowing for tool-free installation, repositioning, and removal anywhere along the track. This flexibility is invaluable for dynamic environments like retail displays, galleries, and exhibition spaces. Architects, lighting designers, and electrical contractors specify the D28 for projects demanding a minimalist aesthetic, superior light quality (CRI up to 95+), and reliable performance backed by a 5-year warranty. It is the ideal choice for creating focused drama and highlighting key features in high-end commercial, hospitality, and residential interiors across the EU, US, and Middle East.

Which spaces is it designed for?

The D28's blend of miniature form, magnetic flexibility, and high-quality light makes it a powerful tool for layered lighting schemes. It excels in applications where objects and displays require focused attention and where the lighting system itself needs to be discreet and adaptable.

How can it be used for accent lighting in high-end retail?

In a luxury boutique or for high-value merchandise like jewellery, the D28 provides the perfect solution. A narrow 15° beam angle can be used to create dramatic, focused highlights on a specific product, drawing a customer's eye. Specifying a high CRI95+ model at 4000K ensures that the colours of fabrics, leathers, and gemstones are rendered with maximum accuracy and vibrancy. The magnetic track system allows staff to easily reconfigure the lighting layout to match new collections or store plans without needing an electrician, providing significant operational savings and flexibility. A well-designed scheme can achieve UGR<19, ensuring a comfortable shopping experience without distracting glare.

What makes it suitable for museum and gallery lighting?

For museums and galleries, light quality and control are paramount. The D28 series delivers on both fronts. Its <3 SDCM color consistency ensures that all fixtures in a gallery emit visually identical light, crucial for uniformly illuminating large artworks. The availability of high-fidelity options (TM-30 Rf>90) guarantees that the artist's original palette is perceived correctly. When integrated with a DALI-2 control system, each 3W spotlight can be individually dimmed down to 1% to meet strict conservation standards, which often specify lux levels below 50 lux for sensitive materials. Our comprehensive IES and LDT photometric files allow curators and designers to model these scenarios accurately in DIALux before installation.

Can it be integrated into modern hospitality and residential projects?

Absolutely. In hotels, restaurants, and high-end homes, the D28 provides elegant and functional accent lighting. Use a series of 3W spots with a 38° beam angle over a dining table or along a corridor to create pools of warm, inviting light (2700K or 3000K). The minimalist design of the fixture and track, especially in matt black, blends seamlessly into contemporary ceilings. With control options like Casambi (Bluetooth Low Energy), homeowners or staff can adjust scenes and dimming levels directly from a smartphone or tablet, offering an intuitive and modern user experience. Its low voltage (48V DC) operation also adds a layer of safety.

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

The D28 fixture is part of a complete 48V magnetic track ecosystem, which includes surface-mounted, recessed (trim/trimless), and pendant track profiles. Installation of the light head is exceptionally simple: it clicks into place magnetically and is secured with a small locking tab, forming both a mechanical and electrical connection. No tools are required.

Control is handled at the system level via the 48V DC driver and appropriate interfaces. We support a full range of protocols:

• DALI-2: For addressable digital control, allowing individual dimming and scene-setting for each light head. Ideal for commercial and museum projects.
• 0-10V / 1-10V: A simple and robust analog dimming solution for global control of all fixtures on a circuit.
• Wireless (Casambi, Zigbee): By using a compatible wireless driver or gateway, the system can be controlled via Bluetooth or Zigbee mesh networks, perfect for retrofits or smart home integration.

All system components are compliant with European standards, including CE (LVD/EMC), RoHS (Restriction of Hazardous Substances), and ErP (Energy-related Products), ensuring market access and safety. Our manufacturing facility is ISO9001 certified, guaranteeing consistent quality control.

Customisation, MOQ and lead time

As a manufacturer, we offer extensive customisation. While Matt White (RAL9016) and Matt Black (RAL9005) are standard finishes, custom RAL colors for the fixture housing can be accommodated for project orders exceeding 500 units. You can specify any combination of CCT, CRI, and beam angle to meet your project's exact photometric requirements. The minimum order quantity (MOQ) for the D28 series light head is 100 units. Standard configuration orders typically have a lead time of 20-25 working days from confirmation to dispatch.

Frequently Asked Questions

Q: What is the complete system needed to run the D28 track light?

A: To operate the D28, you need the 48V magnetic track rail (recessed, surface, or pendant), a 48V DC constant voltage power supply (e.g., from Mean Well or Tridonic) appropriately sized for the total wattage, the D28 light heads, and any required connectors or end caps. The driver converts your mains AC power (e.g., 230V) to safe, low-voltage 48V DC for the track.

Q: Can I get different CCTs and beam angles on the same track?

A: Yes, that is a primary advantage of the system. You can freely mix and match fixtures. For instance, you could place a 3W D28 spot with a 15° beam at 4000K to highlight a product, right next to another 3W D28 with a 60° beam at 3000K for general ambience. The magnetic connection makes this repositioning and swapping instant and tool-free.

Q: What is the typical lumen output and efficacy for a high-CRI model?

A: Performance depends on the specific LED chip. For a typical 3W D28 fixture specified with a premium 3000K, CRI95+ chip, you can expect a lumen output of approximately 210-225 lumens. This results in a fixture efficacy of 70-75 lm/W. A standard CRI80 version at 4000K could deliver a higher output of around 270 lumens, achieving an efficacy closer to 90 lm/W.

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

A: We provide a 5-year warranty on the D28 LED track light. This warranty covers defects in manufacturing, materials, and workmanship under normal use and service. It guarantees against premature failure and ensures LED lumen maintenance will not fall below L80B10 at 50,000 hours, meaning at least 90% of the fixtures will retain at least 80% of their initial brightness after 50,000 hours of operation.
