Quality of Light
At MARK Architectural Lighting, we define quality of light as being humancentric, sustainable, and intentional. It must be welcoming and enhance the human experience, it must be operationally efficient and environmentally friendly, and it must achieve the design intent as defined by the architect or designer.
Bright light energizes us. Softer diffused light helps us relax and be intimate. Vivid lighting sets energy, tone, and color.
Experience and Spacial Perception
Quality lighting helps improve alertness, focus and response, and it improves visibility in work environments, so work is more accurate, and we feel safer.
Performance and Task Visibility
The relationship between artificial lighting and human physiology — alertness, sleep, immune function and more — is becoming increasingly clear.
Well-being and Visual Comfort
High quality light is
Humanistic needs dictate how light is defined and often measured. It shapes what we see and how we interact with and understand a space. The effects of lighting on people in the spaces is being explored in ways we never thought possible 20 years ago.
INTENTIONAL
High quality light is the paintbrush of the architect and designer. It is used to create emphasis and deliver intentional aesthetics, realizing the artistic vision for a space. An artist must have a broad selection of brushes and colors to unleash their full potential.
Quality lighting can be playful and impactful. Luminaries can illuminate architecture while receding to the background, or they can become a part of the architecture itself.
Compliment Architecture
MARK Architectural Lighting offers solutions that allow designers to fine tune illumination layers, to enhance architectural features, and to realize their vision.
Enhance Aesthetics
Safety needs are met in a variety of ways with quality light. Distributed emergency lighting enables entire fixtures to provide emergency functionality, using less energy and providing a well-lit space when needed.
Safety & Security
Quality lighting solutions must evolve and support the development of building codes and standards for constructing environmentally friendly and healthy spaces.
SUSTAINABLE
Providing transparency regarding the materials that make up our luminaires provides our community with the knowledge necessary to make informed decisions. Learn more: Sustainable Design

HUMANCENTRIC
Color Rendering Index grades how accurately a light sources renders color compared to a full-spectrum reference light source. Sunlight CRI = 100
Spectral Power Distribution analysis allows for critical evaluation of light quality by measuring key performance attributes of light source color.
Color Rendering
Analytics Include:
Spectral graphs, exact CCT coordinates and CRI values, DuV, R values, melanopic ratios, and fidelity, gamut, and hue indexes.
MARK Architectural Lighting provides a complete package of sphere IES TM-30 test data to support critical evaluation of color rendering.
The Illuminating Engineering Society has published TM-30-18 to update and expand tools for specifiers to evaluate color performance.

We live in a digital world—and lighting is not an exception. eldoLED® proprietary driver technology creates seamless transitions for flicker-safe deep-dimming, stabile consistent color while dimming, and facilitates embedded lighting control solutions.
LED drivers matter. Quality of light starts with how light is generated, emitted and controlled from the source.
High quality digital LED light sources must provide:
Dimming and Flicker
Wired or wireless control
Simplified code compliance
BACnet BMS integration
Network firmware updates
Advanced scheduling
Future-proof design
MARK Lighting provides a superior quality of light experience through embedded nLight network control solutions. Benefits include:
Embedded controls create a smarter lighting solution that is more adaptive and responsive to its environment.
Embedded Controls
Flicker-safe illumination complying with IEEE 1789 green ‘safe zone’ criteria at all levels
Smooth and efficient dimming to 0.1% while following a natural dimming rate
Consistent chromaticity across the entire dimming range
MARK Architectural Lighting solutions feature
eldoLED Hybrid Hydradrive Technology.
The transition to embedded controls has been fueled by the need for smarter, more sustainable buildings. The result is a simplified approach to design, simplified installation, and fewer inter-operability challenges.
