To wake each day in darkness is a plight you wouldn’t wish on your worst enemy, yet that’s what many of us do routinely throughout winter. Getting up in the dark decouples our life from our circadian rhythm (our body clock), with bodily processes such as cognition and metabolism put to work before they’re fully prepped.
Thank heavens, then, for sunrise alarm clocks. These “dawn simulation” devices glow with gradually intensifying brightness as your wake-up time approaches, kickstarting your circadian rhythm before you get out of bed. For many users, this results in a happier, healthier start to the day.
Not all sunrise alarm clocks are made equal – for instance, only some are bright enough to be medically certified as light-therapy devices for Sad (seasonal affective disorder) and other disorders. We’ve indicated the alarm that has this certification in its spec below.
I snuggled down with seven of the best-rated wake-up lights from Lumie, Beurer, Philips, Dreamegg, Momcozy and Hatch to find out which would make the most difference to my mornings. As a lifelong reluctant riser, I’ve found the experience of testing these devices a gamechanger – in fact, I’m now using one daily. Perhaps mornings aren’t so bad, after all …

Why you should trust me
Mornings, eh? I’ve often felt lousy first thing, after waking up to a minutes-long medley of smartphone alarms.
When, at last, I drag myself out of bed, I frequently spend the day reviewing all kinds of gadgets, from Sad lamps to electric heaters. It’s a freelance job I’ve been privileged to do since 2017 – and as we tumbled dimly into 2025, the Filter gave me one of my most quietly life-improving assignments yet: reviewing sunrise alarm clocks.
The extent to which these gadgets have improved my mornings has surprised me – although it was greater in some cases than others. Frankly, I’d like other groggy wakers to feel the same benefit, and my reviews are written and ranked with this in mind. Our favourite model will be kept for long-term testing.
Some brands did not want the sunrise alarm clocks I sourced for testing back, so those will be donated for fundraising to Cat Action Trust 1977, a small national charity dedicated to the welfare of feral cats.
How I tested
The only proper way to test a sunrise alarm clock is by using it to wake up each morning – so that’s exactly what I did.
I used each model for at least two nights, testing out multiple light and alarm sound settings, and assessing the quality of wake-up for each device. I considered the brightness of each alarm, how close the glow felt to real sunlight, and the audio quality. Above all, I reflected on how lively and refreshed I felt after waking up with each one.
Many sunrise alarm clocks also have a sundown function, so I used this where available too. I also tried using each sunrise alarm clock as a reading light, to help me finish the day – as well as start it – smartphone-free.
Some sunrise alarm clocks go even further, with additional features such as app operability, multiple alarm profiles and mood lighting. To ensure a thorough review of each sunrise alarm clock, I played around with every possible customisation option and functionality.

Lumie Bodyclock Spark 100
I woke up feeling great when I used the medical-grade Lumie Bodyclock Spark 100, which bathes the room in gradually intensifying, sun-like light for a set period before the alarm goes off.
Why we love it
The device is supposed to realistically imitate the lightening shades of a sunrise – and it does so more convincingly than any other sunrise alarm clock I’ve tested. Depending on your chosen light intensity setting, it can get very bright.
The Spark 100 also has a sunset feature that graduates through the same red, orange and white light colours used with the sunrise function, but in reverse order. After the sunset cycle, the light can either switch off entirely or remain in a gentle night-light mode, whichever you choose.
Besides performing brilliantly as a wake-up light and sunset simulator, the Spark 100 is simply a nicely designed, well-made thing. I appreciated its soft-edged yet robust construction and handy features such as the cable organisation in the base. It’s a pleasure to have on the bedside table.
Lumie is the brand that pioneered consumer-grade sunrise alarm clocks in the early 1990s and that pedigree shines through.
It’s a shame that … the alarm tone sounds piercing at the higher three of its five volume levels. I found myself settling for a 2/5 – more than loud enough to rouse this particular heavy sleeper.
Certification: UK MDR 2002 and EU MDR 2017/745 medical classification
Modes: sunrise, sunset, bedside light
Footprint: W19 x D12cm

Best sunrise alarm for late-night reading:
Philips SmartSleep
This lamp soon felt like part of the furniture on my bedside table. In typical Philips fashion, it’s a good-quality, dependable product, with a middle-of-the-road design that won’t look out of place in many bedrooms.
Why we love it
Setup is incredibly slick – I was able to set my alarm time, sound and brightness by following the simple prompts on the device’s display, without having to consult the manual. Subsequently tweaking your alarm(s) takes a bit of practice, but you’ll master all the controls you need after a few days.
The SmartSleep’s wake-up capabilities are impressive, combining brilliant light with a diverse choice of alarm sounds. It also has FM radio and 3.5mm auxiliary audio input options for the user who has tired of Alpine and gong bath soundscapes. There’s a 5V USB charging outlet at the rear of the lamp, too, which could free up a valuable bedside power socket.
I loved using this model as a reading light, as well as a sunrise alarm. Even when a bright setting is selected, the light seems relatively mellow and restful, which helped me get to sleep after reading pulpy detective novels late at night. The light can be deactivated with a press.
It’s a shame that … it costs such a lot. The SmartSleep has a hefty price to match its impressive performance.
Certification: none
Modes: sunrise alarm, sleep mode with sunset simulation, bedside light
Footprint: W22 x D12cm
Features: FM radio, AUX audio input, “RelaxBreathe” breathing exercises, adjustable sunrise duration, snooze, up to two wake-up profiles (with separate alarms)

Best sunrise alarm clock for a gentle awakening:
Lumie Sunrise Alarm
Imagine telling one of your ancestors that you were awoken this morning by your lamp, which was purring at you. I’m not pulling your leg, you might say, it’s all thanks to the Lumie Sunrise Alarm’s “kittens purring” alarm tone, which sits sweetly alongside four other natural sounds, including goats bleating and birdsong.
Why we love it
In all seriousness, this is an excellent sunrise alarm clock, and it comes at a standout price. Its sunrise light subtly brightens during the minutes leading up to your chosen alarm time, producing a lovely awakening that really did remind me of natural light.
I found it easy enough to set the Sunrise Alarm’s time and alarm, although pressing some of the buttons can be fiddly. Do keep the instruction manual handy, as there are lots of options and buttons to get your head around.
It’s a shame that … it lacks a little bedside table appeal. But having said that, this sunrise alarm clock has incredible performance for the price.
Certification: none
Modes: sunrise alarm, sunset, bedside light
Footprint: W17 x D9cm
Features: mood lighting (six colours)

Best sunrise alarm clock for couples:
Beurer Wake-up Light WL50
Thanks to its capability to save two alarms for different times (each with its own sound and light settings), the Beurer WL50 is a great choice for couples who get up at different times. That’s a rare feature in any sunrise alarm clock – let alone in such a reasonably priced model.
Why we love it
The sunrise mode itself is gentle yet effective, and it’s easy to activate the device as a reading light with a simple, groggy tap. I really liked the alarm sounds you get with the WL50 too – which is just as well, as there are only two options.
Perhaps that narrow choice of alarm tones sounds a little stingy, but it seems less so when you explore the WL50’s alternative audio options. It doubles up as an FM radio, with space to save up to 30 station presets, which you can listen to throughout the day or use as a livelier alternative to an alarm tone. Bluetooth connectivity and an AUX input expand your listening options further.
Curiously, this sunrise alarm clock can be unplugged (when fully charged) and used on the go for up to three hours. It’s hard to imagine a situation wherein this would be useful, but I appreciate the gesture.
It’s a shame that … the sound quality isn’t great (but it’s good enough for the half-awake).
Certification: none
Modes: sunrise alarm, sunset simulation, bedside light, radio/speaker
Footprint: W11 x D11cm
Features: FM radio, AUX audio input, Bluetooth audio, portable use (up to three hours), LED mood light
Brightness settings: adjustable

Best value sunrise alarm:
Momcozy Sunrise Echo
The clue’s in the name: the Momcozy Sunrise Echo comes primed with a selection of wake-up sounds intended specifically for mums, dads and their little ones. It’s also tough to topple, soft around the edges and weighs just 0.55kg.
Why we love it
I’m neither a parent nor a baby, but I can certainly hear the soothing quality in the Sunrise Echo’s 30-strong repertoire of wake-up sounds, which includes lullabies alongside the usual nature sounds and meditative drones. The sound quality is impressive, with plenty of mid-range frequencies and a touch of bass. It’s nicely balanced, and not at all jarring.
The Sunrise Echo creates a lilting light effect, rather than intensively light-therapising the sleeper as some higher-powered models do. It was easy to set up and customise the alarm using the well-labelled control buttons around the shoulder of the alarm clock. It was a little harder though, through a fug of sleepiness, to adjust the screen and light brightness via their respective dials on the rear of the device. Nonetheless, the Momcozy Sunrise Echo is an excellent, accessible option for users who don’t want a very bright wake-up.
It’s a shame that … a few nice-to-have features are absent, including FM radio and multiple alarms.
Certification: none
Modes: sunrise alarm, bedside light
Footprint: W19 x D8.5cm
Features: night light (seven colours), sleep aid sounds, digital clock display, adjustable sunrise duration
Brightness settings: 30

The best of the rest

Dreamegg Sunrise 1
Best for: soothing sleep sounds
This compact, great-looking device offers something different, with a selection of 29 ambient sounds that can be used as white noise to help you fall asleep. There are also five options for rousing you in the morning, including birdsong, a campfire crackling and, my favourite, waves breaking on a shore. For me, perhaps the only issue with this approach was that the sounds did a better job of putting me to sleep than they did of waking me up.
The Sunrise 1 is a beautifully designed alarm clock, with a softly textured front and foolproof dimmer controls on either side to adjust the light level and digital display brightness. Reluctant risers will be pleased to note there’s a prominent snooze button at the top of the device – though, personally, I’ve rarely felt the need to use this feature while testing sunrise alarm clocks.
It didn’t make the final cut because … its light is a little too dim for my taste.
Certification: none
Modes: sunrise alarm, white noise/sleep sounds, bedside light
Footprint: W15 x D7.3cm
Features: sleep sound timer, nine light colours, five wake-up sounds
Brightness settings: adjustable

Hatch Restore 2
Best for: customisation and smartphone connectivity
In some respects, this premium sunrise alarm clock has an edge over its competitors. It’s a chic, simple device, with a nicely textured front (similar to that of the Dreamegg Sunrise 1) and two unmissable buttons to activate sleep sounds or wake-up mode.
While the Restore 2 has a pleasant, moderately bright light in a nice range of colours, its sound library is the real standout here. Some of the options – all of which are configurable with the Hatch Sleep smartphone app – are beautifully textured and more lifelike than anything I heard from competing products.
The same Hatch Sleep app gives you access to additional audio content such as relaxing meditations and inspirational moments – but only if you’re willing to shell out £4.99 a month for a Hatch+ subscription. You’ll also need to buy a US-to-UK plug adaptor to use with this sunrise alarm.
It didn’t make the final cut because … the upfront cost of the product and ongoing subscription for paywalled content are off-putting.
Certification: none
Modes: sunrise alarm, white noise/sleep sounds
Footprint: W18.4 x D6.2cm
Features: paywalled content (including meditations and inspirational monologues), smartphone operability and sleep/alarm routine creation
Brightness: adjustable in-app

Do sunrise alarm clocks help with Sad?
Sad bright-light therapy involves the use of very intense light (in the region of 10,000 lux) to mimic the effects of bright sunlight. Sunrise alarm clocks tend to be far less bright than the average Sad lamp. With that said, the effect of light on our circadian rhythms has been shown to peak around the onset of dawn and early in the morning – so a mellow sunrise alarm may provide disproportionate benefits.
If you’ve been diagnosed with seasonal affective disorder and are looking for a light therapy device, it’s best to ask your GP which product to use and how to get the most benefit. Sunrise alarm clocks that are classified as medical devices (indicated below each product above) are more likely to suit users seeking a therapeutic effect than models with no medical certifications.
Why does it benefit us to wake with the sun?
Getting up in the dark can feel awful, which makes a lot of sense because our bodies require light to wake up properly.
Humans are diurnal, which means we’ve evolved to be more wakeful, energetic and capable of chasing mammoths over vast distances during daytime. When the brain recognises increasing light at dawn, it sends signals around other regions of the brain and to other organs to calibrate bodily processes including temperature regulation, hormone secretion and metabolism. And when darkness falls, the brain prepares us for sleep – a helpful effect that many of us compromise by looking at bright smartphone or laptop screens.
These effects, which repeat every 24 hours, are our circadian rhythms. That is derived from the Latin words circa (approximately) and diem (day), meaning around a day.
So, the sun is the original and best alarm clock – activating our minds and bodies with light, rather than startling us awake with sound. Think of your sunrise alarm as a plucky stand-in to rely upon during the star’s shorter winter shifts.
