Flicker-Free Circadian Light
Flicker-Free Circadian Light
Inspired by natural rhythms
The sunset simulation dims from 3500K warm white to 1800K deep amber before sleep, triggering melatonin production so your body actually winds down.
The sunrise simulation reverses this sequence before your alarm, priming natural cortisol release so you wake with clarity. Its wake-up light gradually illuminates 5 to 120 minutes before your alarm clock time

Light is one of the primary signals your brain uses to regulate your circadian rhythm, influencing melatonin and cortisol timing to support natural sleep and waking.

How it works
How it works
01
Before sleep
30–60 minutes before your set sleep time, the light gradually shifts from warm white to deep amber. Your body temperature drops, and you start to feel genuinely sleepy.
02
Before wake
30–90 minutes before your alarm, the light gradually brightens to help you wake naturally. When the alarm sounds, you’re already in a light stage of sleep so you feel clear, not jolted awake.
03
Over time
Over time, consistent sunrise and sunset routines can help you fall asleep faster and wake feeling clearer. Within 1–2 weeks, most users report falling asleep faster, waking less groggily, and having more energy through their shifts.

What Shift Workers Say After 30 Nights
Overall rating: 5.0 / 5 from 4 reviews.
I absolutely love my Circa lamp !The gradual sunrise effect makes waking up feel so much more natural and relaxing, especially on dark mornings here in Melbourne m. It’s easy to use, looks great, and has made my morning routine so much nicer. Definitely recommend it!
This was my bday present and I love it, specially the night light! Sunset mode is very relaxing with the difference sounds.
CircaRhythm has really helped me switch off after long days at work and relax into my night routine. Waking up gradually with light has also been amazing. I feel more refreshed and have much better energy throughout the day.
I love the sunset setting and wake up naturally with light. I don't have the phone on the bedside table any more!
Have Questions?
Your body clock runs on light. Shift work feeds it the wrong light at the wrong time, so it stops knowing when to switch off.
CircaRhythm works through the Light & Sound Reset Sequence — a timed sunset that fades the light warm and low while calming sound drops away, and a sunrise that builds light gradually before your alarm sounds. The same signals your body already knows how to read, delivered on your roster instead of the sun's.
Most alarm clocks wake you up. CircaRhythm tells your body when to sleep.
Because those fix your environment. None of them tell your body what time it is.
Blackout curtains remove light. A white noise app removes sound. CircaRhythm adds the missing signal — light and sound moving together, gradually, in the direction your body needs to go. That's why it sits alongside what you already own rather than replacing it.
If you've had partial results from everything you've tried so far, this is the piece that wasn't in the room.
That's exactly who it was built for.
Most sunrise clocks assume you sleep at night and wake in the morning. CircaRhythm assumes nothing. Two independent alarms for early and late starts, a sunrise you can set anywhere from 5 to 120 minutes, a sunset that runs up to two hours or stays on until you stop it, and a display that dims right down — or off completely — for a blacked-out daytime bedroom.
Nurses, paramedics, FIFO, police, aviation and parents of small children. Rotating rosters are the design brief, not an edge case.
The wind-down usually comes first. Most people notice they're switching off faster within the first few nights, because the sunset gives the nervous system something to follow instead of lying there tired but wired.
Body clock alignment takes longer. Give it a fortnight of consistent use — ideally across a full roster cycle — before you judge it.
That's why the guarantee is 30 nights, not seven. You need a real block of shifts to know.
No. Every function works from the device itself — two knobs, four buttons. Long press to enter a setting, rotate to choose, press to confirm.
The free Smart Life app is there if you'd rather change your alarm from bed or set tomorrow's wake-up while you're still at work. It's optional, there's no subscription, ever, and nothing stops working if you never download it.
Plug it in, set your time, set your sunset. You can be running tonight.
Then send it back.
30 nights, full refund of the purchase price. No interrogation, no hoops. We'd rather you tested it properly across a full roster cycle than kept something that didn't help you.
