Aetheo · Sleep and wake
Seren.
A sunrise before your alarm, a slow sunset before you sleep, and your own music in between.
The idea
An alarm, a lamp, a sound machine and a speaker usually take up four places on the table. Seren is one, and each part works on its own.
06:08 · Before the alarm
Choose how long the sunrise lasts, from 1 to 60 minutes. The light comes on that many minutes ahead and brightens gradually. Then the alarm starts quietly and rises, or stays silent if you would rather wake to light alone.
07:15 · A shared bedside
Each alarm keeps its own time, sound, ambient light and sunrise length, so you can set one for yourself and one for someone else in the room.
22:30 · Winding down
White noise is built in, so the phone can stay out of it. Choose from ten sounds and set the volume from 0 to 30 on the unit.
23:23 · Lights down
Give the Sunset Sleep Timer 1 to 60 minutes, a sound, a colour and a starting brightness. The light dims in stages, and at the end light and sound switch off together.
Sunrise and sunset
A sunrise alarm wakes you with light first and sound second. Set the time you want to be up, then choose how long the sunrise lasts, from 1 to 60 minutes. Seren starts the light that many minutes ahead.
06:30 · Light only
With a 07:00 alarm and a 30-minute sunrise, your chosen light, warm white or one of seven colours, comes on at 06:30 and brightens gradually. There is no sound yet.
07:00 · Alarm time
It begins quietly and rises. Left alone, it rings for ten minutes and then stops by itself.
Still sleepy?
A firm tap anywhere on the casing, enough to rock it slightly. Sound and light stop and return nine minutes later. You can snooze as many times as you need.
Awake
Sound and light stop for that morning.
Set it up
Set the clock before you set an alarm. The times above are an example. Each of the two alarms keeps its own time, sound, ambient light and sunrise length. To wake to light alone, choose A-00, no sound.
The Sunset Sleep Timer is the sunrise in reverse. Light and sound run down over a time you choose, from 1 to 60 minutes, and then both switch off.
22:30 · Moon key
The moon icon shows and the timer starts with the settings it used last, so most nights one press is all it takes.
22:30 to 23:00 · Dimming
With a 30-minute timer, the light dims in stages as the time counts down, so the room grows darker gradually.
23:00 · Timer ends
There is nothing to reach for, and no light or sound left running.
Changed your mind?
The icon disappears and the light and sound go off. Any other key leaves the timer and keeps you in the mode you were in.
Set it up
The times above are an example. Each sound plays and each colour shows as you reach it, so you choose by ear and by eye. Seren keeps your settings for next time. Sound or light can be off, but not both.
How it works
Hold an alarm key, then set the time, the sound, the ambient light and the length of the sunrise. Each sound plays and each colour shows as you reach it, so you choose by ear and by eye.
The sleep timer starts with the settings you used last. Press again to stop it, or let it run until light and sound switch off.
The object
Use it as an everyday bedside light with 30 brightness levels. It returns to the mode you last used.
Choose your ambient light first: warm white or one of seven colours. Start your music, put the phone away and let it play through Seren's wireless speaker. Add a little scent from our Atmos diffuser if you like. When you are ready, press the moon key: the light dims in stages, and when the timer ends, light and music switch off.
12 cm across and 658 g. It needs one USB socket within reach.
Six brightness levels and an off setting, adjusted apart from the lamp. Choose 12- or 24-hour time.
It needs a USB supply to work and has no battery to charge. A small fitted cell only keeps the clock and settings through a power cut.
Compare
How Seren differs from waking to your phone beside an ordinary lamp.
| Aetheo Seren | Phone alarm and a lamp | |
|---|---|---|
| Waking | Light brightens first, then sound rises | Sound at the set time |
| Silent waking | Light only, if you choose | Vibration or sound |
| Evening timer | Light dims in stages, then light and sound off | Switch the lamp off yourself |
| White noise | Ten sounds built in | Usually an app |
| Your own music | Plays through the wireless speaker | The phone speaker |
| On the table | One object | A phone, a lamp and a charger |
The details
Most alarms begin with a noise. Seren begins with light, brightening gradually over the time you choose, and then adds a sound that starts quietly and rises. You can leave the sound out and wake to light alone.
The alarms, the lamp and the ten white-noise sounds all work from the unit itself, so the phone is only involved when you want your own music or podcasts.
Indoor use only. Keep dry. Do not cover the lamp or use it under bedding. Use a CE-marked USB supply rated 5 V DC, 2 A. Unplug before cleaning and wipe with a soft, dry cloth. Do not open the product.
Contains a CR2032 lithium coin cell, soldered inside and not user-replaceable. It keeps the clock and settings through a power cut and does not power the lamp or speaker. Keep away from children; if a cell is swallowed, seek medical help immediately. Not a toy. Listen at moderate volume.
The full manual, in seven languages, is on the Seren manual page.

Seren is a bedside sunrise alarm clock, lamp, white-noise machine and wireless speaker. The light brightens over 1 to 60 minutes before your alarm, and a Sunset Sleep Timer dims the light in stages before light and sound switch off.
No. The box has a USB-A to USB-C cable but no mains adaptor. Use a CE-marked USB supply rated 5 V DC, 2 A.
No. Seren works on external USB power only. A fitted CR2032 coin cell keeps the clock and settings through a power cut, but it does not power the lamp or speaker and cannot be replaced by the user.
Yes. Set the alarm sound to none and keep a light on. An alarm cannot have both its sound and its light switched off.
Only for your own music or podcasts. The alarms, lamp, sleep timer and ten white-noise sounds all work from the unit. If you pair a phone, Seren also takes the time from it.
No. Seren is set up with the keys on the unit, and has no app or voice-assistant control.
Tap the body firmly, enough to rock it slightly. Sound and light stop and return nine minutes later, and you can snooze as often as you like. A light touch will not trigger it.
The light dims in stages as the timer counts down, and at the end light and sound switch off together.
Seren is 12.03 cm in diameter, 23.99 cm high and weighs 658 g.
Delivery is free on every UK order. If it is not right for you, you can return it within 30 days.
