Bring the changing character of natural daylight indoors with scheduled tunable-white lighting—supporting visual comfort, focus and a calmer transition into the evening.
Natural daylight changes in both intensity and colour appearance. Circadian Rhythm Control coordinates compatible tunable-white lighting to create a planned indoor light journey instead of one unchanging scene.
FIXED WHITE LIGHTING
One setting. All day.
Colour appearance remains unchanged even when the time, activity and natural-light conditions have moved on.
CIRCADIAN RHYTHM CONTROL
A lighting character that changes with the day.

01 · PLAN
Define the daily curve
Choose the times and lighting character required for the people and activities in the space.
→
02 · CONTROL
Schedule the transitions
Koolmesh commissioning coordinates gradual changes without repeated manual adjustment.

03 · EXPERIENCE
Tunable white, throughout the day
Compatible luminaires shift colour temperature and light level to suit the intended daily sequence.
Conceptual control path. Available ranges, interfaces and commissioning options depend on the selected Hytronik product, luminaire, driver and project configuration.
Application example and settings
One day. Four purposeful lighting moments.
A scheduled curve can create brighter, cooler light during active periods and warmer, softer light later in the day—while transitions remain gradual.
07:00Morning12:00Midday18:00Evening21:00Night
Cool and energising
Illustrative: 5000–6500 K
A bright morning scene can help the space feel alert, fresh and ready for active work or learning.
Bright and balanced
Illustrative: 4000–5000 K
A balanced neutral-white scene supports visually demanding tasks without making the atmosphere feel harsh.
Warm and softer
Illustrative: 2700–3000 K
Warmer light creates a more relaxed character as work winds down and evening activity begins.
Dim and warm
Illustrative: around 2200 K
A low, warm scene reduces visual stimulation where a calm late-evening atmosphere is appropriate.
These times and colour temperatures are examples, not universal recommendations. Final settings must reflect the supported luminaire range, required illuminance, local guidance, user needs, operating hours and on-site commissioning.
Brightness + colour temperature
The curve controls two lighting dimensions—not colour alone.
These Koolmesh App profile examples show how brightness and colour temperature can follow different daily paths for office and healthcare settings.
They are example profiles rather than universal project settings. Confirm available ranges and final values during product selection and commissioning.
Four key functions
From a lighting idea to a repeatable daily experience.
The value is not a single colour temperature. It is the ability to plan, commission and repeat an appropriate sequence for each space.
01 · DYNAMIC SCHEDULING
Change scenes automatically
Move from cooler active light to warmer evening light according to the project’s daily operating pattern.
ONE CONNECTED LIGHTING JOURNEY
DAILY LIGHT CURVE
Plan. Control. Repeat.
Scheduling, tunable-white output, commissioning and custom curves work together to create the intended experience.
02 · TUNABLE-WHITE OUTPUT
Coordinate colour and brightness
Control compatible lighting so colour appearance and light level work together as part of one planned scene.
03 · KOOLMESH APP
Commission without complex software
Create and adjust lighting behaviour through the Koolmesh App where supported by the selected device and system design.
04 · FLEXIBLE CURVES
Adapt the journey to the space
Use an appropriate curve as a starting point, then refine timing and output for occupancy, activities and project requirements.
Where it adds value
Designed for places where people spend long hours indoors.
The most useful curve depends on the space, the activity and how occupants use it—not simply the time shown on a clock.
01 · OFFICES
Support the working day
Create an active daytime atmosphere and a softer visual transition for late working hours.
02 · CLASSROOMS
Match learning activities
Use scheduled scenes for focused lessons, collaborative work and calmer periods.
03 · HEALTHCARE
Create gentler day–night cues
Plan comfortable changes for spaces operating beyond conventional daytime hours.
04 · WELLNESS & GYMS
Shift with the activity
Move from an energetic training atmosphere toward warmer, more restorative experiences.
