LED Ceiling Light with Low UGR, CRI90, and Tunable White for Office and Commercial Spaces

The Quad Pixel Recessed luminaire is purposefully designed for today’s high-performance lighting environments, where visual comfort, reduced contrast, and advanced glare control are essential. With its finely tuned light distribution and side-lighting technology, Quad Pixel enhances the ceiling plane, creating a soft and seamless transition between fixture and surface. This leads to calmer visual surroundings and improved luminance ratios, all without relying on pendant fixtures.

At just 78 mm in recessed depth, Quad Pixel is ideal for shallow ceiling spaces. It features a high color rendering index of CRI 90 as standard, ensuring superior light quality, while offering an optional Tunable White range (2700–6500K) for dynamic ambient adjustment. Its efficient glare control system maintains a Unified Glare Rating (UGR) of 16.7 and limits maximum workstation luminance to 2799 cd/m²—comfortably below the 3000 cd/m² guideline. The luminaire's luminance contrast against ceilings is also kept minimal, with a typical luminance ratio around 1:25, enhancing visual ease for office or task-heavy environments.

Quad Pixel installs with the same ease as standard LED panels and is designed for modern modular ceilings. Its integrated base plate can be fitted directly between ceiling grids without the need for tools. The supplied driver—available with or without a connection cable—sits outside the luminaire body, and installation depth can be reduced to 57 mm with a side-entry cable option if required.

Crafted from partly recycled injection-moulded ABS/PC and featuring a frosted PMMA acrylic light cone, aluminium LED brackets, and steel framing, Quad Pixel is both durable and sustainable. The high-quality microprismatic diffuser, enhanced with BrightView optic film, ensures even light distribution and exceptional glare suppression. This louvre system delivers a 75° medium beam, ideal for a variety of commercial and institutional spaces.

Lighting control options include a standard flicker-free LED driver with amplitude modulation and Constant Lumen Output (CLO), supporting dimming from 10–100%. For intelligent control, Quad Pixel is available with Organic Response, a wireless system with PIR sensors that enable autonomous, energy-efficient lighting. Luminaires communicate via infrared and radio signals to adapt in real-time based on occupancy—potentially reducing energy consumption by up to 80% compared to traditional systems.

Quad Pixel includes a 2-meter, halogen-free 5G cable and can also be configured with a quick connector or Organic Response plug as needed. The integrated LED light source is available in 3000K or 4000K, with an exceptional rated lifetime of L100 100,000 hours. For the Tunable White version, the rated life is L100 50,000 hours.

Weighing just 3 kg, Quad Pixel is also supported by an Environmental Product Declaration (EPD) currently in development, detailing the luminaire’s life cycle impact. For those seeking a recessed lighting solution that pairs contemporary aesthetics with high visual performance, smart control, and environmental consciousness, Quad Pixel is a stand-out choice.
