Energy-Saving Anti Glare COB-D85 Series LED Downlight 8W

What is the COB-D85 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 requirements of European, American, and Middle Eastern markets. The COB-D85 Series 8W Anti-Glare LED Downlight is a prime example of this philosophy. It is a compact, high-performance recessed luminaire designed for commercial, hospitality, and high-end residential applications where visual comfort and color quality are paramount. Featuring a deep-recessed Chip-on-Board (COB) LED and a precision-engineered reflector, the COB-D85 delivers powerful, efficient illumination with an exceptionally low Unified Glare Rating (UGR) of less than 19, making it ideal for spaces where people work, learn, or relax. Its small Ø85mm trim and Ø75mm cutout make it a discreet yet powerful tool for architects and lighting designers aiming for a clean, minimalist ceiling aesthetic without compromising on light quality or performance. The 8W model produces up to 800 lumens, achieving a high efficacy of 100 lm/W, which supports energy-saving initiatives and compliance with stringent building codes.

Photometric and Electrical Specification

The COB-D85 series is built to specification, allowing designers to select the precise optical and electrical performance characteristics required for their project. We provide full documentation, including IES and LDT photometric files, for seamless integration into DIALux lighting design simulations.

Which spaces is it designed for?

The COB-D85 8W LED Downlight is a versatile luminaire engineered for interior spaces that demand both aesthetic subtlety and high-quality illumination. Its primary design goal is to provide excellent general lighting while maintaining a high degree of visual comfort, making it a preferred choice for specifiers and electrical contractors working on human-centric lighting schemes across Europe and the USA.

How can this downlight enhance a hotel guest room or corridor?

For hospitality environments, the COB-D85 excels at creating a welcoming and luxurious ambiance. Specifying a warm color temperature of 2700K or 3000K combined with a high CRI of >95 ensures that interior finishes and skin tones are rendered beautifully. The UGR<19 rating prevents any harsh glare, allowing guests to feel relaxed. In corridors, the 50° beam provides a uniform wash of light on the floor, improving safety and navigation. Integration with DALI or phase-dimming systems allows for the creation of different scenes, from a bright welcome setting to a subdued evening atmosphere, all from a single fixture type.

What makes it suitable for modern office and educational environments?

In offices, classrooms, and libraries, lighting must support productivity and concentration. The COB-D85 meets the stringent EN 12464-1 standard for workplace lighting, which mandates a UGR of less than 19 to reduce eye strain. A neutral 4000K CCT is typically specified to promote alertness. Furthermore, its high efficacy of 100 lm/W helps building owners reduce operational costs and meet energy efficiency targets like those outlined in the ErP directive. Lighting designers can use our IES files in DIALux to accurately plan layouts that achieve required lux levels (e.g., 500 lux on desks) and uniformity.

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

While its standard 50° beam is geared towards general lighting, the exceptional color quality options make the COB-D85 highly effective in retail spaces. By selecting a CRI>98 version, retailers can ensure that the true colors of fabrics, produce, and other goods are displayed with maximum fidelity. The deep-set, anti-glare design focuses the customer's attention directly on the merchandise rather than the ceiling, creating a more sophisticated and compelling shopping experience. The minimalist matt white or black finishes blend seamlessly into modern retail ceilings.

Installation, Control, and Compliance

The COB-D85 is designed for straightforward installation by professional contractors. It requires a standard Ø75mm ceiling cutout and is secured by two robust spring-loaded clips, ensuring a firm and flush fit in plasterboard or suspended ceilings. The luminaire connects to a remote, external driver, which simplifies maintenance and allows for better thermal management.

Control flexibility is a core feature. We offer drivers compatible with all major control protocols:

• DALI-2: For addressable, digital control in smart building systems.
• 0-10V/1-10V: For simple and reliable analog dimming.
• TRIAC (Phase-cut): For cost-effective dimming in retrofit projects using standard wall dimmers.
• Wireless: Options include Casambi (Bluetooth Low Energy) and ZigBee for app-based control without new wiring.

Compliance is guaranteed for our target markets. The entire assembly is CE marked (LVD/EMC), RoHS compliant, and meets ErP eco-design requirements, ensuring it meets all European safety, environmental, and performance standards. Our manufacturing process is ISO9001:2015 certified.

Customisation, MOQ, and Lead Time

As a manufacturer, we provide extensive customisation to meet specific project needs. Beyond the wide range of CCT and CRI options, the luminaire housing can be finished in any RAL color to perfectly match an interior design palette. Our standard finishes are Matt White (RAL9016) and Matt Black (RAL9005). You can also specify your preferred driver brand from our partners, including Tridonic, Osram, and Mean Well.

The minimum order quantity (MOQ) for a standard configuration of the COB-D85 is 100 units. For custom RAL color finishes, the MOQ is 300 units. Our typical production lead time is 20-25 working days from order confirmation to dispatch from our facility in China.

Frequently Asked Questions

Q: What is the typical Unified Glare Rating (UGR) for the COB-D85 8W downlight?

A: The COB-D85 is engineered for visual comfort. With its deep-recessed Citizen COB chip and specialized reflector, it consistently achieves a UGR of less than 19. This makes it fully compliant with EN 12464-1 standards for interior workspaces like offices and classrooms, ensuring a comfortable, productive environment. The 50-degree beam angle helps maintain this excellent glare control.

Q: Are photometric files available for lighting simulation software?

A: Yes, absolutely. We provide complete photometric data for the entire COB-D series. Both IES and LDT format files are available upon request for accurate lighting design and calculations in software like DIALux or Relux. This allows specifiers to precisely model illuminance levels, uniformity, and UGR for any project, ensuring the final installation meets the design intent within a 5% tolerance.

Q: What is the warranty period and expected lifespan of the LED?

A: The COB-D85 Series LED Downlight comes with a comprehensive 5-year manufacturer's warranty covering the luminaire and the external driver. The Bridgelux or Citizen LED chips used are rated for L80B10 at 50,000 hours, meaning they will maintain at least 80% of their initial lumen output for 50,000 hours of operation, ensuring long-term performance and reliability.

Q: Can I get this downlight in a custom color?

A: While our standard finishes are Matt White (RAL9016) and Matt Black (RAL9005), we offer custom color options to match your project's specific interior design scheme. We can produce the die-cast aluminum housing in any RAL color for a minimum order quantity (MOQ) of 300 units. Please provide the RAL code for a custom quotation and lead time estimate.
