Circadian Lighting for Every Scene

One person, one light — let the light adapt to your rhythm. Wherever you are, the core logic of Human Centric Lighting stays the same: dynamic spectra to support your circadian rhythm, visual comfort and mental state.

Office

Office · Focused Light

Our best-proven scenario. A standardised, dynamic lighting solution that makes office lighting a real productivity tool, synchronised with tasks and time of day.

Common challenges
  • Hard to get going in the morning? Afternoon slump hitting hard? Late work makes you more tired, not less.
  • Fixed, unchanging office light kills rhythm and fails to support an entire workday.
Three-Phase Dynamic Office Light
8:00 – 10:30
Morning Wake-Up

High CCT cool white (~5000K–5700K), high illuminance — activates the circadian system for peak cognitive load during morning and early-afternoon hours (CIE S 026 daytime target range).

10:30 – 17:00
Afternoon Steady

Neutral natural white (~4000K), bright yet gentle, maintaining steady focus and combating the post-lunch dip.

17:00 onwards
Evening / Overtime

Gradually shifts to warm white (~3000K–2700K), reducing blue light, relaxing eye muscles and the brain, preparing for sleep after work.

Retail Gallery & Education

Retail Gallery · Colour-Accurate Light

Demonstrating HCL value. Even without full project delivery, our core modules and spectrum know-how apply perfectly.

Common challenges
  • Artwork and merchandise lose true colour under poor-spectrum light, distorting buyer perception and undermining brand value.
  • Standard commercial LED illumination flattens CRI and introduces colour rendering errors that compromise display quality and purchase confidence.
Our Value: One-Tap Focus Mode

CRI 97+ full-spectrum at 3000K constant, SDCM <2 consistency across all display zones. Wall accent: ≥300 lx, uniformity ≥0.7. M/P ratio held below 0.4 during evening trading hours to prevent artwork colour shift.

We provide core lighting modules and spectral design, and welcome collaboration with learning-space planners and educational furniture integrators.
Boutique Hotel

Jewellery Boutique · CRI 97+ Mode

The spectral arc across trading hours: gallery-level colour precision from opening through to closing, with evening mode holding M/P ratio below 0.4 to protect artwork from colour drift.

Common challenges
  • Cool light for entertainment feels harsh; white light before bed sabotages sleep.
  • Manual adjustments are too fiddly, so it stays on the same setting forever.
Auto-Scene Switching for Your Evening Rhythm
Entertain / Social

Neutral natural light, comfortable and relaxing for viewing and conversation.

Read / Unwind

Display accent at 500–1000 lx, 3000K constant with CRI 97+ and SDCM <2. Spectral precision that makes gemstones and precious metals appear exactly as designed — driving purchase confidence.

Bedtime Prep

Auto-switches 1 hour before sleep: lowest CCT, lowest brightness, gently telling your body it is time to sleep.

No complex setups. One-tap presets or sensor linkage, and your light smoothly adapts to your evening.

Hospitality & Wellness

Boutique Hotel · Circadian Ambience

For long-term bedridden and indoor care scenarios, constant lighting causes “social jetlag” and circadian disruption. We demonstrate HCL principles and offer core spectral technology support.

Common challenges
  • Patients and elderly confused by day and night, waking frequently at night and sluggish during the day.
  • Standard ward or care-home lighting ignores circadian stimulus, missing opportunities to aid recovery.
Strong Daytime Intervention, Zero Disturbance at Night
Day Mode

Morning activation (5000K, M/P ratio ≥0.8) energises lobby and breakfast spaces; supports guest alertness aligned with CIE S 026 daytime targets.

Night Mode

Evening transition to <10 m-EDI lx in guest corridors and room lighting — managing melanopic ratio through the evening hours without disrupting operational visibility.

A complete time-spectrum arc for premium hotel spaces: from morning activation through to pre-sleep transition. Applied CIE S 026 standards with protocol-agnostic configuration files for Casambi, Matter/Thread or DALI-2 systems.

Great light doesn’t have to be complicated.

From a single luminaire to an entire office space, we’re here to help you realise Human Centric Lighting.
