Lighting Recipe Studio’s In. Licht Series Helps You Understand the Daily Rhythm of Light
The first trace of morning daylight fails to wake you.
A single desk lamp leaves you drowsy by mid-afternoon.
And at night, the blue light from screens quietly steals your sleep.
These lighting details — often overlooked — are silently writing your health report.
We spend more than 80% of our day indoors, but have you ever asked: Does this artificial light environment truly match your body’s natural rhythm?
Now, these questions no longer require guessing.
Die In. Licht series of light health measurement devices is becoming a “personal health advisor” for more and more people — helping quantify daily light exposure and optimize indoor lighting environments with evidence.
01 Invisible Influence: Your “Light Diet” May Already Be Imbalanced
“Light is not about being brighter — it must follow the rhythm of the day.”
Healthy lighting research has made one thing clear:
Light regulates far more than vision.
By shaping the body’s circadian clock, it profoundly influences our:
- energy
- mood
- sleep quality
Yet modern life often disrupts our “light diet.”
- Morning commutes through underground spaces provide insufficient activation light
- Offices with uneven lighting accelerate eye fatigue
- Evenings filled with overly bright, poorly tuned lighting or screens delay sleep onset
The core value of In. Licht is transforming these invisible influences into measurable data.
It precisely measures key parameters such as:
- illuminance
- color temperature
- spectral distribution
- circadian metrics such as m-EDI
And compares them against ideal human circadian models — clearly revealing where your light environment is out of alignment.
02 Precision Measurement: From Subjective Feeling to Data-Driven Health
Instead of relying on personal impressions like:
“Is it bright enough?”
“Does it feel comfortable?”
The In. Licht series provides objective measurement dimensions.
A portable wearable device can be carried like a badge, continuously recording all light exposure you experience throughout the day — from morning to night — generating a complete Personal Light Exposure Report.
And when connected to the Welltek OS intelligent healthy space system, its role evolves beyond a standalone device:
It becomes the “light health sensor” of the entire space.
Based on real-time data from In. Licht, the system can intelligently link with:
- curtains
- luminaires
- smart controls
Automatically adjusting indoor lighting so it remains within a healthy circadian range for each time of day.
For example:
- If morning illuminance is insufficient to provide effective activation light, the system can automatically increase full-spectrum daylight simulation lighting
- If evening color temperature remains too high, the system can shift lighting warmer — preparing the body for night mode
03 Scientific Improvement: A Personalized “Three-Phase Good Light” Plan Based on Data
“Morning activates. Daytime stabilizes. Night relaxes.”
The first step in making this scientific principle real is diagnosis — and that is exactly what In. Licht enables.
By analyzing measurement reports, you receive clear, actionable guidance:
• Morning Phase
The report may show insufficient effective morning light.
Solutions may include:
- moving breakfast closer to a window
- scheduling an automatic high-illuminance full-spectrum lamp after waking
• Daytime Work Phase
Data may reveal excessive contrast between the desk and surrounding environment — a key driver of visual fatigue.
Improvement includes:
- adding ambient support lighting
- reducing harsh brightness gaps
• Evening Wind-Down Phase
The device may capture excessive pre-sleep light exposure.
Strategies include:
- enabling night mode on electronic devices
- replacing strong ceiling lighting with softer diffuse sources
For healthy space designers, facility operators, or individuals pursuing high-quality wellbeing, In. Licht combined with Welltek OS builds a complete closed loop of:
Monitoring → Analysis → Intervention
Healthy lighting is no longer a vague concept — it becomes a measurable, verifiable, optimizable process of scientific management.
When night arrives, the In. Licht device quietly records the final data point of the day — and you are already relaxing under circadian-aligned, gentle light.
The “good light rhythm” advocated by the Good Light Group is now transforming from public science knowledge into a practical daily solution for everyone.
To understand light is to take control of light.
What the In. Licht series provides is your right to be informed — ensuring that every beam illuminating your life truly serves your health.
