Circadian lighting explained: bright mornings, warm evenings
Lights that change brightness and colour through the day, following natural daylight. Here's what circadian lighting is and how it works in a home.
What it does
Daylight changes from bright and cool at midday to warm and soft at sunset. Circadian lighting follows the same pattern indoors, using smart globes or fittings that can change their colour temperature and brightness on a schedule.
What it looks like at home
- Mornings: lights brighten gently before your alarm, like a sunrise.
- Daytime: brighter, cooler light for cooking, working and reading.
- Evenings: warmer, dimmer light, instead of harsh white overhead lights.
- Night: a soft, low path light for getting up without switching everything on.
Where to start
- The main bedroom is the usual first room: a gentle morning light makes a noticeable difference to waking up in a dark room.
- Living areas next, where evening lighting matters most.
- It can often reuse your existing light points, so it's mostly a change of globes, switches or fittings.
Pairs well with
Blackout or smart blinds keep streetlights and early sunrise out, so the lighting you choose is the light you get.
Revo's tipHarsh evening lights? Swap the globe you use most after dark for a warm-white one. It's a small change you'll notice straight away.
