N-D90 Series LED Track Light 20-25W Factory

What is the N-D90 Series 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 specification-grade luminaires for demanding commercial applications across the EU, US, and Middle East. The N-D90 Series is our flagship architectural track spotlight, designed for environments where light quality, flexibility, and reliability are paramount. With a compact Ø90mm cylindrical housing, it offers a modular power range from 20W to 35W, making it a versatile tool for lighting designers and electrical contractors. Its core strength lies in its high-fidelity light output, with Colour Rendering Index options up to CRI98+ and tight chromaticity control (SDCM<3), ensuring products, artwork, and architectural finishes are rendered with absolute accuracy. This series is commonly specified for high-end retail accent lighting, museum and gallery object illumination, and dynamic hospitality spaces requiring precise, adaptable lighting.

Which spaces is it designed for?

The N-D90's modularity makes it a powerful choice for a variety of commercial interior spaces. Its precise optical control and high-quality construction allow it to serve equally well as a primary accent light or as part of a layered, general lighting scheme.

How can the N-D90 series be used for high-end retail displays?

For high-end retail, colour accuracy and creating visual focus are critical. The N-D90 excels here with its CRI95+ and CRI98+ options, ensuring that the true colours of fabrics, leather goods, and cosmetics are rendered vividly. By using the narrow 15° or 24° beam angles, designers can punch light onto specific products, achieving illuminance levels of 1500-2000 lux on mannequins or feature displays while keeping surrounding circulation areas at a comfortable 300 lux. This contrast creates drama and guides customer attention. The luminaire's UGR<19 capability ensures visual comfort for shoppers and staff, even with high-intensity accenting.

What makes this track light suitable for art galleries and museums?

Illuminating artwork requires a delicate balance between visibility and preservation. The N-D90 series, when specified with a high-CRI (CRI>95) and high-fidelity TM-30 (Rf >90, Rg ≈100) LED chip, provides museum-grade light quality that reveals the artist's true intent. The availability of warmer CCTs like 2700K and 3000K helps create an appropriate atmosphere and, critically, the LED source emits virtually no damaging UV radiation. The range of beam angles from a tight 15° for small sculptures to a wider 38° for large canvases allows for precise framing of each piece, minimizing light spill and protecting sensitive backgrounds.

Can this luminaire adapt to changing layouts in a hotel or office common area?

Flexibility is key in modern hospitality and agile office design. The N-D90 on a track system is inherently adaptable; luminaires can be moved, re-aimed, or have their optics changed without an electrician. When integrated with advanced control systems like DALI or Casambi, the lighting can be completely reconfigured through software. This allows hotel lobbies or office breakout zones to transition from a bright, energetic daytime scene (4000K, 500 lux) to a warm, relaxed evening setting (3000K, 150 lux) automatically. The Dim-to-Warm (DTW) option elegantly mimics the warming effect of incandescent dimming, perfect for restaurants and bars.

Installation, Control, and Compliance

Designed for seamless integration into projects in Europe and North America, the N-D90 is supplied with a choice of high-quality track adapters from brands like Global, Powergear, and Eutrac, ensuring compatibility with standard 3-circuit and single-circuit track systems. The installation is a simple 'click-and-lock' process, allowing for rapid deployment and reconfiguration.

Control flexibility is a core feature. We offer drivers for all major protocols:

• DALI-2: For addressable, digital control in smart building systems.
• 0-10V / 1-10V: For simple and robust analogue dimming.
• Phase-cut (TRIAC): For retrofit projects using traditional dimmer wiring.
• Wireless: Casambi (BLE) and ZigBee options for app-based control and minimal wiring.

Full IES and LDT photometric files are available for every variant of the N-D90 series, enabling accurate lighting simulations in software like DIALux and Relux. All models are CE, RoHS, and ErP compliant, meeting all necessary safety, environmental, and energy efficiency requirements for the European market. Our manufacturing facility is ISO9001 certified, guaranteeing consistent quality control.

Customisation, MOQ, and Lead Time

As a lighting manufacturer, we specialize in tailoring products to specific project needs. The N-D90 can be customized in several ways, including non-standard CCTs, specialized CRI/TM-30 outputs, and custom housing finishes from the RAL colour chart. Our standard Minimum Order Quantity (MOQ) for the N-D90 series is 100 units. For custom RAL finishes or highly specialized LED configurations, a higher MOQ may apply. Standard production lead time is typically 20-25 working days from order confirmation. We work closely with our clients to establish a delivery schedule that aligns with their project timeline.

Frequently Asked Questions

Q: What is the typical lumen efficacy for a 3000K, CRI90+ version?

A: A typical 3000K, CRI90+ N-D90 luminaire delivers a system efficacy of approximately 95-105 lm/W. This ensures excellent performance and compliance with energy regulations like the ErP directive, balancing high-quality light output with efficient power consumption of around 25W for a 2625-lumen package. This provides powerful accent lighting without compromising energy targets.

Q: Are custom housing colours available for large projects?

A: Yes, customisation is a core service. While our standard finishes are Matt White (RAL9016) and Matt Black (RAL9005), we can accommodate custom RAL colour requests for project orders exceeding 200 units. This allows for perfect integration with your interior design scheme. Lead times for custom colours are typically extended by 5-7 working days.

Q: Which track systems are the adapters compatible with?

A: We supply the N-D90 series with adapters compatible with the most common global track systems, including 3-circuit standards like Global Trac Pro, Eutrac, and Stucchi. We also offer options for single-circuit and other proprietary systems upon request, ensuring seamless installation for both new builds and retrofits across Europe and North America.

Q: What is the warranty period and expected lifetime?

A: The N-D90 series is covered by a comprehensive 5-year warranty. The luminaire is engineered for a long operational life, with a rated lifespan of L80B10 at >50,000 hours. This means that after 50,000 hours of use, at least 90% of the fixtures will still maintain a minimum of 80% of their initial lumen output, ensuring long-term performance.
