Circadian Rhythm Lighting
Lighting that follows the sun, the way human biology has been calibrated for millennia. The science is well established. The electrical work is what makes it real.
Your body clock is real. Your lighting should respect it.
The human eye contains specialised photoreceptors (intrinsically photosensitive retinal ganglion cells, ipRGCs) that are most sensitive to short-wavelength blue light (peak at ~480nm). These cells send signals directly to the suprachiasmatic nucleus, your brain's circadian clock, suppressing melatonin production and keeping the body in alert mode.
Standard LED downlights emit significant blue-spectrum light, right up until you turn them off at night. The result is measurably delayed melatonin onset, harder sleep initiation, and poorer sleep quality. Research published in the Journal of Pineal Research (2019) found that just two hours of evening blue-enriched light exposure delayed melatonin onset by around 30 minutes. That's not theory. That's your actual sleep schedule being shifted every night.
Circadian lighting design corrects this at the electrical level. Cool white in the morning, transitioning through warm white during the day, to amber by evening. The interactive guide below shows exactly what this means for your biology and your space.
Full Home Circadian System Design
A considered lighting plan that shifts through the day, zone by zone, space by space, so your home works with your biology, not against it.
Bedroom & Sleep Space Priority
Bedrooms, bathrooms, and lounges used in the evening, the spaces where melatonin protection matters most, prioritised first.
Smart Dimmer & Controller Installation
Automated or manually adjusted systems, wired cleanly and correctly. The electrical work done properly so the system actually performs.
Retrofit & New Build
We work with existing homes and new builds. New builds get the cleanest result. Retrofits are still very worthwhile and usually straightforward.
Fixture Selection Advice
We advise on the right colour temperature fittings for each space. Not just what to wire, but what to install in it.

Cool White
Cool white light closely mimics midday sunlight. It signals wakefulness to the brain, suppresses melatonin production, and supports focused activity. Excellent in the morning and task-based spaces.
