D90 Series Surface Mounted Modular LED Pendant Light 10-30W

What is the D90 Series Surface Mounted Modular LED Pendant 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 in the EU, US, and Middle East. The D90 Series Surface Mounted Modular LED Pendant Light is a prime example of this commitment, offering a highly versatile and specification-grade luminaire for commercial and hospitality interiors. This cylindrical pendant, with a diameter of 90mm and a length of 190mm, is designed for projects requiring precise optical control, exceptional colour quality, and seamless system integration. With selectable power outputs ranging from 10W to 30W, it can be adapted for general, task, or accent lighting roles. Its modular design philosophy extends to optics, drivers, and colour rendering, making it a single-product solution for diverse applications, from a boutique hotel lobby to a corporate headquarters. The core of the D90's value proposition is its customisability, backed by robust engineering and premium components from world-leading suppliers.

Which spaces is it designed for?

The modularity of the D90 series allows it to be specified in a wide range of commercial environments where performance and aesthetics are equally important.

How can the D90 Series enhance a retail or hospitality environment?

In retail and hospitality, lighting directly influences customer experience and sales. The D90 pendant excels with its high-CRI options (up to CRI 98+ and high TM-30 Rf values), which render colours of merchandise, food, and decor vividly and accurately. Use the narrow 15° or 24° beam angles to create dramatic accent lighting on displays or tables, drawing attention to key areas. For hotels and restaurants, the Dim-to-Warm (DTW) option allows the ambience to transition from a bright, welcoming 3000K to a cozy, intimate 1800K candlelight glow, perfect for evening service. Suspended in clusters over a bar or reception desk, they create a modern, high-end focal point.

What makes this fixture suitable for modern office and co-working spaces?

For modern workplaces, visual comfort is non-negotiable. The D90 Series can be configured with optics that achieve a Unified Glare Rating (UGR) of less than 19, complying with the EN 12464-1 standard for office lighting. This minimizes eye strain for employees working on screens. Its versatility is key: use the 38° or 60° beam angles for focused general lighting over collaboration zones or breakout areas. When integrated with a DALI-2 control system, the fixtures can support daylight harvesting and scene-setting in meeting rooms, contributing to both employee well-being and energy savings under ErP guidelines.

Can this pendant be used for museum or gallery accent lighting?

Yes, the D90 is an excellent tool for museum and gallery lighting designers. The primary requirement here is exceptional colour quality and precise control, both of which are core strengths. The CRI 98+ option ensures that artwork is displayed with the highest possible fidelity. The tight 15° beam provides precise 'punch' to highlight sculptures or individual paintings from a distance without spill light. Furthermore, the availability of brand-name drivers like Tridonic ensures smooth, flicker-free dimming down to 1%, which is critical for conservation and for creating dramatic visual hierarchies within an exhibition space.

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

The D90 is a surface-mounted pendant, designed for straightforward installation onto a standard ceiling junction box. The luminaire is supplied with a colour-matched canopy and an adjustable suspension cable (standard length 1.5m, customisable).

Control system integration is seamless. We offer drivers for all major protocols specified in the EU and US:

• DALI-2: For addressable, intelligent lighting systems offering two-way communication and advanced control.
• 0-10V / 1-10V: A reliable and widely used analogue dimming standard.
• Phase-cut (TRIAC): For retrofit projects using standard leading/trailing edge wall dimmers.
• Wireless: We offer Casambi (Bluetooth Low Energy) and ZigBee options for simplified installation and flexible app-based control.

All configurations are CE marked, fully RoHS compliant, and designed to meet the latest European Ecodesign (ErP) regulations, ensuring your project meets all legal and environmental standards.

Customisation, MOQ and lead time

As a manufacturer, we specialise in tailoring products to project requirements. For the D90 Series, customisation options include non-standard CCTs, special housing finishes (any RAL colour), and specific driver or LED chip combinations not listed as standard.

The Minimum Order Quantity (MOQ) for standard configurations is 50 units. For customisations such as a unique RAL colour, the MOQ may increase to 200 units. Our typical production lead time is 20-25 working days from order confirmation to dispatch. For large or highly customised orders, please consult our team for a detailed project timeline.

Frequently Asked Questions

Q: What is the typical lumen output for the 25W version at 4000K?

A: The 25W D90 pendant with a standard CRI 80+ chip at 4000K CCT typically delivers an output of approximately 3,125 lumens from the luminaire. This equates to a high efficacy of 125 lm/W. Specifying a higher CRI of 95+ will slightly reduce the output to around 2,500 lumens, a common trade-off for superior colour quality. Exact figures are available in the IES file.

Q: Can I specify a custom RAL colour for a large project?

A: Absolutely. We can produce the D90 series in any custom RAL colour to match your project's interior design scheme. A minimum order quantity of 200 units typically applies for custom powder coating. This process may add approximately 5-7 working days to the standard production lead time. Please provide the specific RAL code when requesting a quotation for accurate pricing.

Q: Is the Dim-to-Warm (DTW) option compatible with standard TRIAC dimmers?

A: Yes, our Dim-to-Warm (DTW) functionality is available with TRIAC (phase-cut) dimmable drivers, making it suitable for both new builds and retrofits. The DTW technology smoothly transitions the colour temperature from 3000K at 100% brightness down to a very warm 1800K at minimum brightness, perfectly mimicking the behaviour of a dimmed incandescent lamp. We can provide a list of compatible dimmer models.

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

A: The D90 Series comes with a comprehensive 5-year warranty. This warranty covers the failure of the LED module (defined as lumen depreciation below 70% of initial output or catastrophic failure) and the LED driver. It assumes the product is operated within its specified environmental conditions (IP20, indoor use) and for a maximum of 4,500 hours per year. The external finish is covered against manufacturing defects.
