K-D90 Series LED Track Light 20-35W

What is the K-D90 Series and where is it specified?

At XHLWX (led-project-light.com), a Custom Indoor LED Lighting Manufacturer based in China, we engineer luminaires for the demanding European, US, and Middle Eastern markets. The K-D90 Series is a specification-grade LED track luminaire designed for applications requiring exceptional color quality, precise optical control, and long-term reliability. With a compact D90xH108mm cylindrical housing, it offers a scalable power range from 20W to 35W, making it a versatile tool for lighting designers and electrical contractors. Its core strengths lie in its modularity, allowing for customisation of CCT, CRI, beam angle, driver, and control protocol to meet the exact needs of high-end retail, gallery, hospitality, and commercial projects. The die-cast aluminium construction ensures superior thermal management, guaranteeing stable performance over its 50,000-hour lifespan.

Photometric and electrical specification

The K-D90 Series is built with premium components to meet stringent international performance standards. We provide complete photometric data, including IES and LDT photometric files, for integration into DIALux and other lighting design software.

Which spaces is it designed for?

The K-D90 Series is engineered for dynamic commercial environments where lighting quality directly impacts customer experience, perception of value, and occupant comfort. Its adaptability makes it a primary choice for retail, cultural, and hospitality sectors across the EU and US.

How can the K-D90 enhance a high-end retail display?

In high-end retail, accurate color rendering is non-negotiable. The K-D90 excels with its CRI >98 and high R9 (>90) options, ensuring that textiles, leathers, and brand colors are rendered with absolute fidelity. The narrow 15° beam angle is perfect for creating dramatic accent lighting, drawing a customer's eye to hero products with up to 3000 lux on target. The track system allows for rapid reconfiguration of displays, providing flexibility for seasonal changes without needing an electrician.

What makes this fixture suitable for museum and gallery lighting?

For museums and galleries, the priority is artifact preservation and visual accuracy. Our K-D90 fixtures with CRI >95 and a CCT of 3000K provide museum-quality light with minimal UV output. The precise optical control allows curators to achieve conservation-safe light levels (e.g., 50-150 lux) while maintaining excellent visual clarity. Using DALI or Casambi control, individual fixtures can be dimmed to fine-tune the balance of light within an exhibition, ensuring compliance with TM-30-18 standards for color fidelity (Rf) and gamut (Rg).

Is the K-D90 a good choice for modern hospitality or office spaces?

Absolutely. In hospitality, creating atmosphere is key. The K-D90 with Dim-to-Warm (DTW) technology can shift from a functional 3000K down to a cozy 1800K candlelight glow as it dims, perfect for restaurants and hotel lounges. For modern offices and co-working spaces, the 38° and 60° beam angle options, combined with a 4000K CCT and a UGR<19 rating, provide comfortable, glare-free general illumination that enhances productivity and well-being.

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

Installation is straightforward with tool-free mounting on standard 3-circuit or DALI tracks from major European brands like Global, Eutrac, and Powergear. We offer a comprehensive suite of control options to meet any project requirement. For building-wide management systems, DALI-2 drivers provide granular addressability, energy monitoring, and diagnostics. For retrofits and flexible spaces, our integrated Casambi BLE mesh drivers allow for powerful wireless control from a smartphone or tablet. Standard 0-10V and TRIAC (phase-cut) dimming options are also available for simpler installations.

All K-D90 models are fully certified with CE (covering LVD and EMC directives), RoHS (Restriction of Hazardous Substances), and ErP (Energy-related Products), ensuring full compliance for specification and import into the European market.

Customisation, MOQ and lead time

As a manufacturer, we provide extensive customisation. Beyond standard options, we can supply the K-D90 with specific CCTs (e.g., 3200K), custom RAL powder coat finishes to match brand aesthetics, and specialized optic or driver combinations. The minimum order quantity (MOQ) for standard configurations is 50 units. For custom finishes or non-standard components, the MOQ may be higher. Standard production lead time is approximately 20-25 working days from order confirmation, with shipping to the EU, US, and Middle East arranged via air or sea freight.

Frequently Asked Questions

Q: Can I get photometric data for lighting simulations?

A: Yes. We provide comprehensive IES and LDT photometric files for all variants of the K-D90 Series. These files are essential for accurate lighting design in software like DIALux or Relux. Upon request, we can typically deliver the required data files within 24 hours, ensuring your project planning is not delayed. Our engineering team can also provide support.

Q: What does the 5-year warranty cover?

A: The 5-year warranty covers the complete luminaire against manufacturing defects. This includes the LED COB chip, the driver, and the physical housing. We guarantee lumen maintenance of at least 70% of the initial output (L70B10) for 50,000 hours of operation under specified ambient temperatures (Ta 25°C). The warranty ensures peace of mind and long-term performance.

Q: What is the typical color consistency between fixtures?

A: We maintain extremely tight color consistency, guaranteeing a rating of less than 3-step MacAdam ellipses (SDCM <3). This ensures that all fixtures specified with the same CCT, for example 3000K, will have no visible color difference when installed together. This is a critical performance metric for professional applications like retail and art galleries.

Q: Which wireless dimming systems are supported?

A: The K-D90 Series offers integrated support for several wireless protocols, most notably Casambi (Bluetooth Low Energy mesh) and ZigBee 3.0. These drivers are built directly into the fixture adapter, simplifying installation. This allows for sophisticated scene setting, scheduling, and individual luminaire control from a mobile app or wireless switches, making it ideal for retrofits where running new control wiring is impractical.
