Which spaces is it designed for?

The COB-D140's combination of high-fidelity light and low-glare comfort makes it ideal for environments where people work, shop, and relax.

How can it improve visual comfort in modern office environments?

For office projects in Europe and the US, achieving UGR<19 is a mandatory requirement for workstation areas under standards like EN 12464-1. The D140 series is engineered to meet this target, reducing eye strain and improving concentration. When spaced correctly, a grid of 20W versions with a 55° beam can provide a uniform 500 lux on the task plane. The high CRI (>90) and stable color (SDCM<3) create a pleasant and productive atmosphere, while the flicker-free driver options are critical for spaces where video conferencing is common.

Is it suitable for high-end retail and hospitality projects?

Absolutely. In high-end retail, color is currency. Specifying the D140 with a CRI98+ option and TM-30 values of Rf>95 ensures that the colors of merchandise—from fashion to produce—are rendered with exceptional accuracy and vibrancy, encouraging sales. The narrow 24° beam is perfect for creating dramatic accent lighting on displays. For hotels, a warm CCT of 2700K or 3000K provides a welcoming ambiance in lobbies, corridors, and guest rooms, while the deep-recessed light source prevents uncomfortable glare for guests.

What are its benefits for museum or gallery accent lighting?

The primary concerns in museum lighting are color fidelity and conservation. The COB-D140 excels here with its CRI98+ and high R9 value options, revealing the true texture and hue of artwork. The 24° spot optic allows for precise highlighting of exhibits from typical ceiling heights. Furthermore, its compatibility with DALI and 0-10V dimming systems enables curators to set precise light levels (e.g., 50 lux for sensitive textiles) and integrate the luminaires into complex scene-setting controls.

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

Installation is streamlined for professional contractors. The luminaire fits a standard Ø120mm cutout and is secured by two robust, pre-mounted spring clips, making it suitable for ceiling thicknesses from 5mm to 25mm. The remote driver is connected via a simple plug-and-play connector.

Control flexibility is central to the D140's design. We offer drivers for all major protocols:

• DALI-2: For certified interoperability in smart building systems.
• 0-10V / 1-10V: For simple, cost-effective analogue dimming.
• TRIAC (Phase-cut): For residential and retrofit applications using standard wall dimmers.
• Wireless: Casambi (BLE) and Zigbee options are available for projects requiring minimal new wiring.

The series is fully compliant with European directives, holding CE marking (LVD & EMC), RoHS for hazardous substances, and ErP for ecodesign, ensuring it meets project specifications across the EU.

Customisation, MOQ and lead time

As a manufacturer, we offer extensive customisation. Beyond the standard options, we can provide specific CCT bins (e.g., 2200K), custom RAL powder coat finishes, or pre-configured driver settings. We can also integrate specialised optics for wall washing or asymmetric distributions for specific project needs.

• Minimum Order Quantity (MOQ): Our standard MOQ is 100 units. Smaller quantities may be possible for project samples.
• Lead Time: For standard configurations, our typical production lead time is 20-25 working days from order confirmation to readiness for dispatch from our facility in China.

Frequently Asked Questions

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

A: The COB-D140 Series comes with a comprehensive 5-year warranty. This covers manufacturing defects, premature failure of the LED driver, and lumen depreciation below 70% of initial output (L70B50) within the warranty period. It assumes operation within the specified ambient temperature range of -20°C to +45°C.

Q: Can I get this downlight with a tunable white CCT range?

A: Yes, customisation with tunable white LED chips is available for project orders with an MOQ of approximately 200 units. A typical range is 2700K to 6500K, controlled via a DALI Type 8 (DT8) driver. This allows for human-centric lighting schemes that adjust color temperature throughout the day.

Q: What is the flicker performance of the recommended drivers?

A: With our recommended premium drivers from Tridonic or Osram, the flicker percentage is typically below 3%, making it imperceptible to the human eye. We can also supply drivers that are fully compliant with the IEEE 1789 standard, ensuring a flicker-free output in the 'no observable effect' range, which is crucial for TV studios and sensitive applications.

Q: How does the anti-glare design achieve a UGR<19 rating?

A: The Unified Glare Rating (UGR) of <19 is achieved through a multi-faceted optical design. The COB LED is positioned deep within the fitting, which is the first step in shielding it from direct view. Secondly, the faceted darklight reflector is engineered to precisely control the light, cutting off beams above a 65-degree viewing angle to prevent high-angle glare.
