Circadian Rhythm Control - Human Centric Lighting

Let light follow your natural rhythm


Your body runs on an internal clock — and light plays a key role in keeping it in sync. Hytronik’s Circadian Rhythm Control brings the dynamic changes of natural daylight indoors, adjusting color temperature and brightness automatically from dawn to dusk to improve health, focus, and comfort.

Do you know poor lighting can disrupt sleep, reduce productivity, and cause fatigue? 

Why Fixed White Lighting Falls Short

While natural light changes, traditional lighting stays the same — and that’s where the problems start.

- In offices and classrooms, static light can cause eye strain and reduce alertness during long hours.
- In healthcare settings, poor lighting may disrupt patient sleep patterns, slowing recovery.
- In wellness and fitness spaces, mismatched lighting can hurt performance or relaxation.


If light doesn’t adapt to your rhythm, your body has to work harder to adjust — costing you energy, comfort, and focus.


How Hytronik Makes the Difference

Hytronik’s Circadian Rhythm Control is designed to bring the benefits of natural daylight indoors with dynamic tunable white lighting. The system automatically adjusts color temperature and brightness to match the human circadian cycle. Using our intuitive Koolmesh App, you can create energizing morning light, balanced midday light, and warm evening light without complicated programming.

 From Dawn to Night — A Light That Changes with You

 Just like the sun, our system shifts its tone and brightness throughout the day to match your body’s needs.

🌅 Morning (7:00 AM) – Cool, energizing white light

Start your day right with bright, cool white light (5000K-6500K) that mimics the morning sun.


- Stimulates cortisol production to boost alertness and focus
- Helps reset your internal clock for a productive day
- Creates an energizing environment for waking up and preparing for tasks

☀️ Midday (12:00 PM) – Bright, balanced light

Maintain peak performance with balanced, natural white light (4000K-5000K) that sustains energy without causing glare.


- Supports sustained attention and reduces eye strain
- Enhances mood and motivation during busy work or study periods 
- Mimics natural daylight to keep circadian rhythm on track

🌇 Evening (6:00 PM) – Warm, softer tones

Wind down with warmer, softer light (2700K-3000K) that helps your body prepare for rest.


- Encourages melatonin production for relaxation
- Reduces blue light exposure, minimizing sleep disruption
- Creates a calming atmosphere to transition from work to personal time

🌙 Night (9:00 PM) – Dim, warm light

Prepare for restful sleep with dimmed, warm amber light (~2200K).


Signals your body that it’s time to rest and recover 
- Minimizes stimulation to the nervous system
- Supports healthier sleep patterns and overall well-being

 “This daily light journey is the foundation of healthy circadian rhythm support.”
