Which spaces is it designed for?

This downlight excels in environments demanding both aesthetic appeal and high functional performance. Its anti-glare properties and superior color rendering make it suitable for a wide range of commercial applications.

How can it achieve accent lighting in high-end retail?

The COB-D180 is perfect for creating powerful focal points. Using the 24° narrow beam optic with a CRI98+ chip, retailers can achieve illuminance levels exceeding 1500 lux on merchandise, making colours appear vibrant and true-to-life. The deep-recessed light source ensures that shoppers' attention is drawn to the products, not the ceiling, eliminating distracting glare and enhancing the luxury shopping experience.

What are the benefits for hotel corridors and lobbies?

For hospitality environments, the primary goal is guest comfort. The COB-D180, specified with a 3000K CCT and a 55° wide beam, provides a warm, inviting ambient light. Its UGR<19 rating is critical in preventing glare for guests moving through spaces. When integrated with a DALI-2 control system, lighting levels can be automatically adjusted to save energy during late-night hours while maintaining a safe and welcoming atmosphere, reducing operational costs by up to 60%.

Is it suitable for modern office and meeting room lighting?

Absolutely. The COB-D180 meets the stringent requirements of the European EN 12464-1 standard for office lighting, which mandates a UGR of less than 19 for workstations. Using a 4000K CCT, these downlights provide a neutral, productive light that can be planned to deliver a uniform 500 lux at desk level. We provide complete IES and LDT photometric files for all variants, enabling designers to perform precise lighting calculations in software like DIALux to guarantee compliance and visual comfort.

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

The COB-D180 series is designed for straightforward installation with a Ø160mm cutout and secure spring clips suitable for ceiling thicknesses from 5mm to 25mm. We offer a comprehensive suite of control options, including standard non-dimmable drivers and various dimming protocols such as 0-10V, TRIAC phase-cut, and DALI-2 for seamless integration into building management systems. For ultimate flexibility, we also support wireless control via Casambi (BLE) or Zigbee. All configurations are fully certified with CE (LVD/EMC), RoHS, and ErP, ensuring compliance for projects in the European market and guaranteeing safety and energy efficiency.

Customisation, MOQ and lead time

As a manufacturer, we specialise in customisation. Beyond the standard Matt White and Matt Black finishes, we can supply the COB-D180 in any RAL colour to match your interior design scheme. We can also accommodate requests for specific CCTs, drivers from preferred brands, or unique dimming solutions. The minimum order quantity (MOQ) for standard models is 50 units. For custom RAL finishes or non-standard configurations, the MOQ is typically 200 units. Standard production lead time is 15-25 working days from order confirmation, with express options available.

Frequently Asked Questions

Q: What level of color quality can I expect from the highest CRI option?

A: Our highest specification uses a CRI98+ COB chip, delivering exceptional color fidelity with an R9 value over 90, crucial for rendering reds accurately. These models also achieve outstanding TM-30 metrics (Rf ≈ 95, Rg ≈ 102), ensuring that the full spectrum of colors appears saturated and natural. This makes it a perfect choice for art galleries, museums, and high-fashion retail where color accuracy is non-negotiable. SDCM is maintained at <3 for consistency.

Q: How does the anti-glare design work and what is the typical UGR?

A: The excellent glare control comes from a combination of factors. The COB LED is deeply recessed within the housing, shielding it from direct view. This is paired with a high-purity, specular-faceted reflector that precisely controls the light beam. This design achieves a Unified Glare Rating (UGR) well below the 19 required for offices, often testing at UGR<16 in typical applications, ensuring maximum visual comfort for occupants.

Q: What is the warranty, and which premium driver brands are available?

A: The COB-D180 series comes with a comprehensive 5-year warranty covering the entire luminaire, including the LED driver. We standardise on world-class driver brands to ensure reliability and performance. For DALI or 0-10V systems, we typically specify Tridonic or Osram drivers. For TRIAC dimming, we often use TCI or HEP. This component flexibility allows us to meet specific project requirements while ensuring a lifespan of over 50,000 hours.

Q: Are photometric files available for lighting simulation software?

A: Yes, complete photometric data is available for lighting designers and specifiers. We provide IES and LDT files for every combination of power (20W/25W), CCT (2700K-6500K), and beam angle (24°/38°/55°). This enables you to accurately model the COB-D180's performance in DIALux, Relux, or AGI32, ensuring your lighting scheme meets all technical and aesthetic requirements before installation. These files are available for immediate download upon request.
