Light is more than illumination — it shapes how we feel, think, and perform. The Infinity system, implemented by Light4U and based on Lumitech technology, brings the rhythm of daylight indoors. By combining Tunable White and RGB in one light source, Infinity mimics the dynamic behaviour of sunlight. It automatically adapts to time, activity, and emotion — creating light that supports people, not just spaces.
Light that follows nature
Human well-being is deeply connected to the circadian rhythm, our internal clock that reacts to light and darkness. Bright, cool light in the morning promotes alertness and focus. In contrast, warmer tones in the evening help the body relax. Infinity’s Tunable White feature recreates this natural rhythm indoors. As a result, it helps maintain balance between productivity and rest.
With a broad range from 1,800 K to 16,000 K, Infinity can deliver anything from soft candlelight to cool blue daylight. It ensures smooth transitions with MacAdam 1–2 step consistency, so shifts in tone and intensity always appear natural. In offices, classrooms, and healthcare spaces, these gentle changes support concentration, energy, and mood. Meanwhile, in hotels and homes, they enhance comfort and atmosphere — bringing natural harmony to interior light.
Tunable White with precision
Infinity uses two calibrated white channels — one warm and one cool — that blend seamlessly to achieve any desired colour temperature. Designers can adjust lighting manually or program automatic cycles that follow the rhythm of daylight. This flexibility gives full control over both aesthetics and function.
The main advantages include smooth CCT adjustment from 1,800 K to 16,000 K, a high CRI (Ra9) for accurate colour rendering, flicker-free dimming from 1–100%, and consistent colour stability across all luminaires. Together, these features make Infinity both visually comfortable and technically precise — ideal for architectural and human-centric lighting design.
Easy control and automation
Infinity Tunable White integrates effortlessly with several control systems. It supports DALI DT8 for wired installations, Casambi for wireless control, and Zigbee for smart building integration. Each option ensures easy operation and scalable control for any project size.
When installed in a DALI network, automatic circadian lighting can be achieved using the Lunatone DALI CDC. This device continuously adjusts colour temperature and brightness throughout the day, simulating the natural daylight cycle. Known as Human Centric Lighting, this approach helps create spaces that follow natural biological rhythms.
The DALI CDC communicates seamlessly with DALI DT8 Tunable White luminaires equipped with Infinity modules. It sends precise commands to ensure imperceptible transitions, creating lighting sequences based on time and location. Users can activate, modify, or pause these sequences through Lunatone’s DALI Cockpit software. Once configured, the system operates autonomously — offering time-based daylight simulation with minimal maintenance.
Infinity across luminaires
Infinity’s Tunable White technology is available across several Light4U luminaire families, ensuring consistent performance across an entire project. It can be applied in the following ranges:
- Cimbri, Baldr, Fenrir, and World recessed downlights for offices, schools, and hospitality projects;
- Sana adjustable recessed luminaires for retail and commercial applications;
- Skadi surface, suspended, and track-mounted luminaires for architectural use;
- Thor track spots designed for retail and modern office environments.
This variety enables designers to create human-centric lighting consistently across workplaces, public areas, galleries, and hotels — all using one unified Infinity system.
Human-centric light, engineered with care
Every Infinity luminaire combines optical precision with stable thermal management, guaranteeing lasting performance. Each unit is tested and calibrated in-house to maintain identical colour temperature, luminous flux, and dimming behaviour. This ensures a consistent lighting experience throughout any installation.
The result is a system that merges technical accuracy with human comfort — made for architects, designers, and engineers who value precision, well-being, and purpose in light.
The natural rhythm of Infinity
Infinity Tunable White transforms lighting from static to dynamic. It brings daylight indoors — programmable, controllable, and seamlessly integrated into architecture. From offices that enhance focus to hotels that invite relaxation, Infinity delivers light that feels natural, looks refined, and responds intelligently. When light follows life, people thrive.
