Technical Quality & Architectural Performance
At Beton Lighting, our products are engineered to strict photometric standards. Every fixture undergoes rigorous spectroradiometer testing to ensure color consistency, color fidelity, glare cut-off, and thermal longevity.
Color Temperature (CCT)
Correlated Color Temperature (CCT) measures light warmth in Kelvin (K). Tuned spectrum options span ultra-warm ambient hospitality tones to crisp neutral daylight for focus work environments. Preset spectral binning ensures precise color temperature consistency across all architectural fixtures in a project.
Color Rendering Index (CRI Ra 90+)
CRI measures how accurately a light source reveals natural colors compared to sunlight (Ra 100). High CRI Ra 90+ LED engines ensure vibrant architectural materials, textiles, and artwork without grey tinting. Enhanced R9 red spectrum values preserve natural wood tones, human skin tones, and rich interior finishes.

TM-30 & Low Glare Optics (UGR < 19)
Unified Glare Rating (UGR) quantifies visual glare discomfort. Deep-recessed dark light reflectors keep UGR below 19 to eliminate eye fatigue, backed by IES TM-30 Rf 92+ color fidelity spectrum analysis. Optically engineered baffles and cut-off angles shield direct light sources for supreme visual ergonomics in high-end spaces.
MacAdam Ellipse (SDCM < 3)
Standard Deviation Color Matching (SDCM) measures color consistency across LED chips. 3-step MacAdam binning guarantees zero visible color hue variance between fixtures installed along continuous walls, coves, and corridors.
