# Best Sunrise Simulator Alarm Clock 2026: The Light Nobody Measures Source: https://www.ranked10.co.uk/home/best-sunrise-simulator-alarm-clock Published: 2026-09-13 | Updated: 2026-09-13 | Prices checked on Amazon UK on 2026-09-13 A sunrise alarm clock is a light you cannot measure. Ten clocks were collected for this ranking and not one of them publishes a lux figure: not the £54.99 one with Alexa, not the £29.99 one with the deepest sample, not one. What they publish instead is counting. Seventeen atmosphere lights. Thirty soothing sounds. Eight colours. Twenty brightness levels. Fourteen lighting modes. Four alarms. Ten to sixty minutes. Every one of those numbers is about the light, and none of them has a unit — atmosphere lights are not lights, they are moods, and thirty sounds describe a speaker. There is no question a shopper can put to any of these listings that a figure here would answer: you cannot ask how bright, only how many. The house already has one article on this site where the same question is answered properly. In the SAD lamp ranking, every lamp states its output in lux at a distance — the Lumie Mini 10,000 lux at twelve centimetres, the only kind of number that makes a lamp comparable with another lamp. A therapy lamp and a bedside clock are not the same purchase: one is for sitting in front of, the other for waking gradually. But the difference between the two articles is not the product, it is the specification. Both markets sell light. One writes down what it sells. The clearest proof arrived in a single listing. The ecozy at number four, at £54.99 with app and Alexa control, advertises 17 atmosphere lights in its bullet points and, in the specification block on the same page, records its number of lights as one. Both sentences were written by the same seller, a few centimetres apart, and the brand's other listing in this ranking — number seven, the same 17 atmosphere lights bullet, £47.51 — enters seventeen in that field. One of the two numbers is right. Nothing on either page tells a buyer which, and this article will not pretend to know. The carelessness is distributed evenly across the ranking. The ARUQO at number three, which carries the best rating here — 4.9 stars from 101 ratings, 93 per cent of them five — fills its alarm clock field, a yes-or-no question, with a list of four product names, gives its theme as Christmas, Easter, Fantasy, Halloween and Love, and enters its size as S. It is also the only clock in this article that answers the question the product exists to answer: ten to sixty minutes, adjustable, for how long the sunrise takes. A ten minute sunrise is an alarm; an hour is a way of waking up without one. Nine other listings mention a sunrise mode and none names its duration. The Foryond at number two, which has the deepest sample here at 2,850 ratings, publishes two different sizes for the same object — 16 by 7.5 centimetres in one field, 23 by 6 by 21 in another — and that is a 44 per cent difference in the width of a thing you have to fit on a table. Where real quantities appear, they appear alone. Two of the ten clocks state a wattage: 5 watts on the RETEYUNG at number nine, whose specification also gives its bulb shape as A19, the code for a household screw bulb that the device does not contain and cannot replace, and 10 watts on the blonbar at number ten, which describes itself in the next field as battery powered. Three listings use a field called clock form and fill it with the word sunrise, which is a light effect and not a form of anything. Weights range from 330 grams on the lightest clock to 760 on the heaviest, a factor of two and a third, and the sizes from a ten centimetre bedside column to the 23 centimetres one listing claims for itself. The only genuinely comparable number in the whole market is a rank: the LIORQUE at number one is 149th in Alarm Clocks, and it is the only listing here that says so. The ratings tell the story of what a buyer can judge. The two best are 5.0 stars from 71 ratings and 4.9 from 101 — small samples with emphatic scores — while the clocks with thousands of buyers settle between 4.2 and 4.4, including the £54.99 ecozy at 4.2 from 2,373 and the blonbar at 4.2 from 353, whose distribution carries five per cent one-star and seven per cent two-star where the leaders sit above seventy per cent five. And the sentence that stands in for every missing lux figure came from a review of the clock at number one: the buyer calls it a great alarm clock and adds that the light could go a little brighter. That is the measurement this market does not print, written by the only person who can see it. ## The ranking ### 1. LIORQUE Wake Up Light Sunrise Alarm Clock with White Noise, 400g - Price: £29.99 | Amazon rating: 4.4 from 743 ratings - Full review: https://www.ranked10.co.uk/home/best-sunrise-simulator-alarm-clock/liorque-149 - Buy on Amazon: https://www.amazon.co.uk/dp/B0FB9CWT4D?tag=ranked10-21 £29.99, and the only listing in this ranking that publishes where it stands: 149th in Alarm Clocks. The only sunrise clock in this article that tells you what the market already thinks of it. Its specification block carries a best sellers rank: 33,600th in Home and Kitchen, and 149th in Alarm Clocks. Every other listing here sells the light by counting — 17 atmosphere lights, 30 sounds, 8 colours, 20 brightness levels — and none of those counts has a unit or a witness. A category rank is not a lux reading either, but it is a number produced by thousands of other people's purchases rather than by a copywriter, and it is the closest thing this market offers to evidence. The rest of the page is competent rather than remarkable: 30 white-noise sounds, 12 levels of adjustable brightness, a warm and cool white option and a gentle breathing light, all in a body of 400 grams with a fabric cover. Its rating is 4.4 stars from 743 ratings, which is a serious sample. What makes it first, though, is one review that says the thing this whole article is about. The buyer likes the clock, calls it great, and adds that the light could go a little brighter. In a market where not one of the ten listings publishes a brightness in lux, the only measurement of the light is a sentence from someone who owns it. At £29.99 it is also the second-cheapest clock here, and the one we would buy first: the deepest evidence of quality for the money, and a documented weakness you can decide about before you pay. Pros: The only published best sellers rank here: 149th in Alarm Clocks; 743 ratings at 4.4 stars; 12 brightness levels, warm and cool white; 30 white-noise sounds; £29.99: the second-cheapest clock in this ranking Cons: No lux figure, like every clock here; A buyer finds the light dimmer than expected; Fabric body: 400 grams, but wipe-clean only; No wattage published ### 2. Foryond Sunrise Alarm Clock, Dual Alarm, 9-Minute Snooze, 760g - Price: £34.99 | Amazon rating: 4.3 from 2,850 ratings - Full review: https://www.ranked10.co.uk/home/best-sunrise-simulator-alarm-clock/foryond-2850 - Buy on Amazon: https://www.amazon.co.uk/dp/B0FLXSH6N2?tag=ranked10-21 £34.99 with 2,850 ratings, and a listing that measures its own clock two different ways. The deepest sample in this ranking by a distance: 2,850 ratings at 4.3 stars, six times the next-largest clock here. That matters more than any feature list in a market where eight of the ten listings publish no wattage and none publishes a brightness in lux: two thousand eight hundred people have lived with this alarm in the dark, and the reviews describe a gentle wake-up, multiple sounds, and one use case worth quoting — a buyer who says it is great for night workers who use black-out blinds. That is the person a sunrise clock is actually for. The hardware is straightforward. Two alarms with a nine-minute snooze, knobs and buttons rather than an app, ten white noises, a digital display and both sunrise and sunset simulation. Its weight is 760 grams, the heaviest of the compact clocks here, and the listing gives two sizes for the same object: an item dimension of 16 by 7.5 centimetres and a size field of 23 by 6 by 21 centimetres. A clock that is either sixteen or twenty-three centimetres wide is a fitting question before purchase, and the same page produces both numbers without noticing. It comes second rather than first because the evidence is better but the light is not: 2,850 buyers cannot tell you whether the sunrise is bright enough, and the specification — like all ten here — does not say. It is the clock to buy if the alarm needs to be dependable and the app is not wanted, and at £34.99 it sits in the middle of the price range. Pros: 2,850 ratings at 4.3 stars: the deepest sample in this article; Dual alarms with a nine-minute snooze; Knobs and buttons, no phone required; Sunrise and sunset simulation; A buyer names its genuine use: night workers with black-out blinds Cons: Two different sizes published for one clock; 760 g: the heaviest compact clock here; No wattage and no lux figure; No app or Bluetooth control ### 3. ARUQO Sunrise Alarm Clock, 10-60 Minute Sunrise, 330g - Price: £33.99 | Amazon rating: 4.9 from 101 ratings - Full review: https://www.ranked10.co.uk/home/best-sunrise-simulator-alarm-clock/aruqo-10-60 - Buy on Amazon: https://www.amazon.co.uk/dp/B0H2Y5WF4D?tag=ranked10-21 £33.99 for the only published sunrise duration here — 10 to 60 minutes — and 4.9 stars from 101 ratings. The only listing in this article that answers the question a sunrise clock is bought to answer: how long does the sunrise take? Its specification says ten to sixty minutes, adjustable, and it is the single most useful number in this ranking — because a sunrise that runs for ten minutes is an alarm, and one that runs for an hour is a way of waking without an alarm at all. Not one of the other nine clocks states a duration. Several mention a sunrise mode; none says what it costs in minutes. It is also the best-rated clock here, at 4.9 stars from 101 ratings with 93 per cent of them five stars, which is a small sample and an emphatic one. The hardware matches: 330 grams, the lightest in the ranking, eight colours, twenty brightness levels, thirty sounds, and a three-level brightness control on both the lamp and the clock display. A buyer notes that it can run on batteries or be plugged in, which is the difference between a bedside clock that survives a power cut and one that does not. The page is also the worst-written in this article, and the contrast is the point. Its alarm clock field, which on other listings reads yes, contains a list of four separate product names; its theme field lists Christmas, Easter, Fantasy and Halloween for a device that simulates dawn; and its size is given as S. Somebody filled in a specification form as if it were a search index. The measurement that matters survived, which is why this clock is third rather than lower — and why, when a listing does give you a number, it is worth reading the rest of the page with a raised eyebrow. Pros: The only published sunrise duration here: 10 to 60 minutes; 4.9 stars from 101 ratings, the best rating in this ranking; 330 g: the lightest clock in this article; 8 colours and 20 brightness levels; Runs on battery or mains Cons: The alarm clock field is a keyword list, not a yes; Theme field lists Christmas and Halloween; Size given as S; 101 ratings: a small sample for a 4.9 rating ### 4. ecozy Sunrise Alarm Clock, App and Alexa, 17 Lights, 2373 Ratings - Price: £54.99 | Amazon rating: 4.2 from 2,373 ratings - Full review: https://www.ranked10.co.uk/home/best-sunrise-simulator-alarm-clock/ecozy-17-or-1 - Buy on Amazon: https://www.amazon.co.uk/dp/B09YHBRHC4?tag=ranked10-21 £54.99 with app and Alexa control, 2,373 ratings — and a listing that counts its lights twice, differently. This is the listing that contains this article's argument in a single page. In the bullet points the ecozy advertises 17 atmosphere lights, alongside 22 sleep-aid sounds and an FM radio. In the specification block, on the same page, the field marked number of lights says one. Both were written by the same seller and neither has been reconciled since, and the phrase atmosphere lights is the reason: it is not a count of lamps, it is a mood, and once a mood is put in a countable field the arithmetic stops meaning anything. The evidence that it is carelessness rather than fraud is the brand's other listing reviewed further down this ranking, which uses the same 17 atmosphere lights bullet and enters 17 in the field. One of the two numbers is right. A shopper cannot tell which, and this article will not pretend otherwise. What is genuinely specified is the software. This model is controlled by app and by Alexa, connects over Wi-Fi and Bluetooth, and runs four alarms with snooze, a sunset routine and 22 sounds including an FM radio. Its rating is 4.2 stars from 2,373 ratings — the second-deepest sample here and the lowest rating of the four leaders, which is the pattern to expect when a product asks more of its buyer: an app that must be set up, an account, a network. At £54.99 it is the dearest clock in this article by some margin, and the one to choose if the alarm should be told to change by voice from a pillow. The light is the same unmeasured gradient as everywhere else in this ranking, with one extra number attached that nobody, including its own listing, believes. Pros: App and Alexa control, over Wi-Fi and Bluetooth; Four alarms with snooze and a sunset routine; 22 sleep sounds plus an FM radio; 2,373 ratings: the second-deepest sample here Cons: Its own listing says 17 lights and one light; 4.2 stars: the lowest rating of the four leaders; £54.99: the dearest clock in this article; Set-up needs an app, an account and a network ### 5. AUYLE Sunrise Alarm Clock, LED Sunrise Simulation, 14 Light Modes, 540g - Price: £35.99 | Amazon rating: 4.3 from 166 ratings - Full review: https://www.ranked10.co.uk/home/best-sunrise-simulator-alarm-clock/auyle-led-method - Buy on Amazon: https://www.amazon.co.uk/dp/B0FJ5ZRQ24?tag=ranked10-21 £35.99, and the only listing here that describes the light by its method — LED-based sunrise simulation — instead of by a count. Among ten listings that sell the light by counting, this one describes the method. Its lighting field reads sunrise simulation, LED-based, which is the only sentence in this article that explains how the effect is produced rather than how many of something it contains. It is not a specification a buyer can compare — an LED-based gradient says nothing about brightness — but it is the honest shape of an answer, and the shape is what the other nine avoid. On the same page, in the same specification block, the light count reads one, while the bullets promise fourteen lighting modes, six solid colours and eight RGB moods. One light and fourteen modes is not a contradiction in the way the ecozy's is, but it is the same habit: a countable field filled with a number that counts something else. The rest of the clock is mid-market and sound. Thirty sounds including white and pink noise and a fan, a sleep timer, a digital display, RGB lighting and a USB port, in a body of 540 grams whose dimensions are given as about 17 centimetres square — depth, width and height, in that order, which is an unusual order to publish a size in. Its rating is 4.3 stars from 166 ratings, a modest but coherent sample with seventy per cent five-star. At £35.99 it costs more than the LIORQUE that leads this ranking and a pound more than the ARUQO, and it earns its place on the method field rather than on the price: if the reason for buying is understanding what the light does, this is the only page here that says. Pros: The only listing here that names the lighting method; 30 sounds including white, pink and fan noise; RGB lighting plus a USB port; Dimensions given as depth, width and height Cons: One light in the count, fourteen modes in the bullets; No lux and no wattage; 540 g: heavier than the leaders; £35.99: dearer than the clock that leads this ranking ### 6. APUZOM Sunrise Alarm Clock, 0-100% Dimmable Display, Linen, 480g - Price: £34.98 | Amazon rating: 4.6 from 118 ratings - Full review: https://www.ranked10.co.uk/home/best-sunrise-simulator-alarm-clock/apuzom-0-100 - Buy on Amazon: https://www.amazon.co.uk/dp/B0GS53YLS2?tag=ranked10-21 £34.98 for a linen-bodied clock with a 0-100 per cent dimmable display — a real percentage, and the only one here. The only percentage in this article, and it belongs to the display. The APUZOM advertises a clock display that dims from zero to one hundred per cent, which is a genuine scale with defined ends — off, and fully on — and it is the closest any listing here comes to treating light as something with a quantity. Note what it measures, though: the digits, not the sunrise. On this page, as on every other, the light that wakes you is a mode with three levels, while the number on the clock face is the one that gets a zero-to-one-hundred range. The listing's other unusual strength is materials. The body is given as ABS with linen fabric, two materials named where most of this market names none, and the design follows from it: a columnar lamp of 480 grams, ten and a half centimetres wide and fifteen tall, which is the smallest footprint in this ranking and the easiest to fit on a crowded bedside table. Thirty sounds, eight colours, three brightness steps, dual alarms, and a battery backup that takes one C cell — the listing says it is included, which is how a bedside clock survives a power cut and keeps the time. Its rating is 4.6 stars from 118 ratings, the second-best of the leaders, and the reviews are specific rather than enthusiastic, which is a better sign: a buyer calls it brilliant on dark mornings, and another reports that the sunrise wake-up actually works and the sound quality is good with a wide volume range. At £34.98 it is a sensible middle purchase — a small, well-described object whose one precise number describes the wrong lamp. Pros: A 0-100 per cent dimmable clock display: a real scale; Materials named: ABS and linen fabric; The smallest footprint here at 10.5 by 15 cm; Battery backup with a C cell included; 4.6 stars from 118 ratings Cons: The percentage applies to the display, not the sunrise; Only three brightness steps for the light; The sunrise duration is not stated; No app or Bluetooth ### 7. ecozy Sunrise Alarm Clock, Bluetooth Time Sync, 17 Lights, 449g - Price: £47.51 | Amazon rating: 4.3 from 621 ratings - Full review: https://www.ranked10.co.uk/home/best-sunrise-simulator-alarm-clock/ecozy-17-in-field - Buy on Amazon: https://www.amazon.co.uk/dp/B0DRW6TWXS?tag=ranked10-21 £47.51 for the ecozy that does count its lights — 17 in the field as well as the bullet — with Bluetooth time sync. The other half of the contradiction at the centre of this article. This is the same brand, the same 17 atmosphere lights promise and the same product family as the app-controlled ecozy reviewed above — and this listing puts seventeen in the number of lights field, exactly where the other puts one. Two pages, one shared marketing sentence, two answers to a countable question. Neither listing has a reason to lie: the phrase atmosphere lights simply does not define a unit, so one copywriter treated the number as a count and the other treated it as a description. If a shopper wants to know how many lamps are in the box, the honest answer is that this market cannot tell them. What this model offers instead is convenience. It pairs over Bluetooth and synchronises its clock from a phone, so the time is set by the device in your hand rather than by three buttons on a plastic case — a small feature that matters every spring and autumn, and more often than that when a power cut resets a bedside clock. There are 26 sounds across 16 volume levels, a graded red-to-warm sunrise and an equally graded sunset, seventeen atmosphere lights for mood, and a body of 449 grams. Its rating is 4.3 stars from 621 ratings, and the reviews are about exactly this: buyers describe waking naturally rather than being startled, and one calls the white noise a genuine help for light sleeping. At £47.51 it costs eighteen pounds more than the LIORQUE that leads this ranking, and the extra buys Bluetooth, seventeen lights that may or may not be seventeen, and a synchronised clock. That is a fair trade for a bedside device, and a worse one for a light. Pros: Sets its own clock from a phone over Bluetooth; 26 sounds with 16 volume levels; Graded sunrise and sunset light; 4.3 stars from 621 ratings Cons: Its twin counts the same lights as one; £47.51: £18 more than the clock leading this article; No lux figure, as everywhere here; Atmosphere lights remain undefined ### 8. AFEXOA Sunrise Alarm Clock with White Noise, 30 Non-Looping Sounds, 520g - Price: £30.58 | Amazon rating: 5.0 from 71 ratings - Full review: https://www.ranked10.co.uk/home/best-sunrise-simulator-alarm-clock/afexoa-5-stars - Buy on Amazon: https://www.amazon.co.uk/dp/B0GKFFD9FQ?tag=ranked10-21 £30.58 and the only perfect rating here — 5.0 stars, from 71 ratings — with 30 sounds that do not repeat. The only perfect rating in this article, and the reason it is eighth rather than first is written underneath it: 5.0 stars from 71 ratings, where the clocks above it carry 743, 2,850, 101 and 2,373. A perfect score from seventy-one buyers is a good sign and a thin one; the same perfection from twenty-eight hundred would decide this ranking on its own. What the sample does say clearly is that nobody who bought this clock at £30.58 has yet found a reason to complain in public, which in a market of dim lights and fiddly apps is not a small thing. Its distinguishing feature is a phrase most listings here would not bother with: thirty non-looping sounds. Every other clock in this ranking advertises thirty sounds and stops; whether those sounds loop is the difference between a white-noise machine that helps you sleep and one that begins to feel like a dripping tap by the fourth repetition. It is the kind of claim that gains nothing from exaggeration — a recording either repeats or it does not — and it is the only listing here that has thought about it. The rest of the page is standard-issue for this price: dual alarms with snooze, a digital display, adjustable brightness and volume, USB-C power and a round body of 520 grams, 21 centimetres across. One buyer's summary is the reason to consider it anyway: the buyer says it is a good alarm clock, with nice sounds to wake to, easy to set, and now they do not rely on their phone. That is the straightest statement of what this product category is for, and it comes from the cheapest listing in this article with a full score. Pros: 5.0 stars: the only perfect rating in this ranking; 30 sounds, described as non-looping; Dual alarms with snooze; USB-C power; £30.58: the cheapest clock in this article with a full score Cons: 71 ratings: the thinnest sample in this ranking; No lux and no wattage; 520 g: heavier than the smaller clocks here; No app or Bluetooth ### 9. RETEYUNG Moon Lamp Sunrise Alarm Clock, 5 Watts, 8 Lights, 969 Ratings - Price: £33.24 | Amazon rating: 4.3 from 969 ratings - Full review: https://www.ranked10.co.uk/home/best-sunrise-simulator-alarm-clock/reteyung-5-watts - Buy on Amazon: https://www.amazon.co.uk/dp/B0DCP9DB5G?tag=ranked10-21 £33.24 for one of the only two clocks here with a real wattage — 5 watts — and a bulb shape on a lamp that has no bulb. One of only two listings in this article that publishes a wattage, and the smaller of the two: five watts, for a moon-shaped lamp that also wakes you with a simulated sunrise. Five watts is a real quantity, and it is the kind of number a buyer can compare — with the 10 watt clock further down this ranking, and with the 4 watt stove fan and the 5.7 watt sibling reviewed elsewhere on this site, all of which at least agree about the order of magnitude. What it does not tell you is the one thing that matters here: how bright the light is when it reaches your eyes, which depends on the optics and the distance as much as on the power. A five watt lamp a metre from a pillow is a guess; the SAD lamp ranking on this site is where the same question is answered with lux. The rest of the specification shows the same mixture of care and copy-paste as the rest of the market. The light count is eight, which is plausible for a moon lamp with a gradient. The bulb shape is given as A19, which is the code for a standard household screw lamp — on a device whose light source is integrated and cannot be replaced, and which does not contain an A19 bulb at any point in its life. Its bullet points also contain a changelog: one of them explains that in the new version the wake-up light alarm has moved from the second alarm to the first, and asks the buyer to configure it accordingly. Two product generations described in one description, on a listing with 969 ratings and 4.3 stars. At £33.24, in a market where the light is unmeasured, a stated wattage and a stated light count are worth more than a mood: this is a reasonable purchase for someone who wants a moon lamp that also wakes them, and the honest answer for someone who wants the brightest sunrise they can get is elsewhere in this article. Pros: A real wattage: 5 W, one of only two here; A light count of 8, plausible for a moon lamp; Dual alarms with a 10 minute snooze; 969 ratings at 4.3 stars Cons: A bulb shape of A19 on a lamp with no bulb; A changelog inside the bullet points; 5 W says nothing about brightness in lux; Two product generations in one description ### 10. blonbar Alarm Clock with Wireless Charger, Wake-Up Light, 10 Watts - Price: £31.99 | Amazon rating: 4.2 from 353 ratings - Full review: https://www.ranked10.co.uk/home/best-sunrise-simulator-alarm-clock/blonbar-10-watts - Buy on Amazon: https://www.amazon.co.uk/dp/B0D5M5QKVS?tag=ranked10-21 £31.99 for a wake-up light that also charges a phone — and a 10 watt figure described as battery powered. The only clock in this article that will also charge your phone: a wireless charging pad built into the base, which is a genuinely useful idea beside a bed and the reason this listing exists at all. It also publishes a wattage of ten watts — the higher of the two real wattages here — and that is where the page stops agreeing with itself, because the same specification describes the power source as battery powered. Ten watts from a battery is not impossible in principle; a bedside device that consumes ten watts continuously from a cell is not a product anyone sells, and the field is almost certainly a mistake left from a template. It is the same fault as the A19 bulb shape on the lamp above and the solar power declared by a mains clock excluded from this ranking: fields filled with the nearest available option, never re-read. Its record is the weakest part of it. A rating of 4.2 stars from 353 ratings is the lowest in this article, and the distribution behind it is worse than the average suggests: five per cent of buyers gave it one star and seven per cent gave it two, against sixty-four per cent at five, where the leaders here sit above seventy. Cheap wireless charging pads are notorious for inconsistent coils and hot phones, and a device that combines a charging pad with an alarm and a light has three jobs to get wrong. The light itself is unmeasured, as it is on every clock here. At £31.99 it is not the cheapest way to be woken by a sunrise, and it is the only one that will also leave a phone charged on the bedside table. Buy it for the charging pad and accept the rating; buy the LIORQUE at number one for the alarm. Pros: A wireless charging pad built into the base; A real wattage: 10 W, the higher of the two here; Cheaper than the app-controlled clocks; One object instead of two on the bedside table Cons: 4.2 stars: the lowest rating in this ranking; Five per cent one-star and seven per cent two-star; Ten watts described as battery powered; Another A19 bulb shape on a lamp with no bulb ## Verdict What we would buy. The LIORQUE at £29.99 is the one we would buy, and the reason is the whole article in one line: it is the only listing here that publishes where it stands in the market — 149th in Alarm Clocks — with 743 ratings at 4.4 stars, twelve brightness levels, a 400 gram body and a buyer who tells you the light could go a little brighter. If the sunrise matters more than the alarm, the ARUQO at £33.99 is the only clock that says how long it lasts, ten to sixty minutes, and it carries the best rating here at 4.9 stars from 101. If dependability and no app are the priorities, the Foryond at £34.99 has 2,850 ratings, dual alarms, a nine minute snooze and knobs you can operate half asleep. If the light on your bedside table is genuinely part of a treatment for dark mornings, buy a therapy lamp instead and this is the wrong ranking: the SAD lamp article on this site is where every product publishes 10,000 lux at a stated distance, and it is the only place on the site where the light is a number. And if what you want is one fewer cable by the bed, the blonbar at £31.99 charges a phone on its base — accept 4.2 stars from 353 ratings, with a fifth of buyers at two stars or fewer. What the listings will not tell you. Treat every count as decoration, because none of them is a unit: seventeen atmosphere lights and thirty soothing sounds describe a mood and a speaker, and the same product can be seventeen lights on one page and one light on another from the same brand. Ask for the sunrise duration before you buy, because only one clock in this ranking states it and the difference between a ten minute and a sixty minute sunrise is the difference between an alarm and waking up by yourself. Look for a wattage if you want any anchor at all, knowing that only two of ten clocks give one and that five watts does not mean five watts of light in your eyes. Measure the space on the table, as the sizes claimed here run from a ten centimetre column to a figure of 23 centimetres for a clock whose own listing also says 16. Read the distribution and not the average, especially on the cheapest clocks with charging pads. And if the light is the reason you are reading, remember what no page here will admit: this market sells you a sunrise, and none of it will tell you how bright the sun is.
