Bonoch \ok-to-wake\” Smart Nursery Light Review: Soothing Sounds And Light For Sleeping And Waking”

by -149 views

Every bit a health journalist, I’ve followed developments in light therapy over the past decade and a one-half. For this guide, I interviewed 2 sleep researchers and three lite scientists virtually the usefulness of sunrise simulators for everyday wakefulness, and I consulted with several colleagues as well equally my husband, all of whom have been using wake-up alarm clocks for more than a year.

If it’southward difficult for you to wake up in the morning, or if yous find it harder equally the days grow darker in the fall and winter, a sunrise alert may help you experience less groggy. Biologically, people are wired to wake up as the sun rises, and wake-up-calorie-free alert clocks are designed to simulate that result, starting with a dim light that builds upwards to the brilliance of a brilliant spring day over the course of about thirty minutes. (Withal, if you have trouble getting out of bed, a dedicated wake-up alarm clock probably remains best.)

You might be wondering how a sunrise alert works, considering that your eyes are airtight when y’all sleep. It turns out that your optics are not simply for seeing but also for adjusting your biological clock (only as your ears aren’t only for hearing but too for helping y’all maintain your balance). Inside the retina are calorie-free-sensitive cells that detect light changes at dawn and sunset, sensing low-cal even if your optics are closed. Once detected at dawn, light of sufficient intensity helps to suppress your levels of melatonin. This may make y’all feel less tired.

You don’t really need a special clock to wake yourself upward with light—whatsoever ol’ lamp with a timer volition exercise. The simple introduction of bright light itself may be helpful to beat out jet lag, but there’south something about the gradual reveal of light that makes these clocks more appealing to folks who aren’t morning people, who despise the jolt of a conventional alert, or who demand aid rolling out of bed during darker fall and winter mornings. 1 pocket-sized study that asked subjects to do math bug and go biking after waking up suggests that dawn simulation could be useful for reducing sleep inertia and getting your daytime on. Preliminary studies suggest that it can lower the risk of heart attacks (PDF).

Sunrise alert clocks may be helpful for people with seasonal affective disorder or a clinically diagnosed example of delayed slumber-phase syndrome. Merely you tin can’t rely on these clocks solitary as treatment. The typical treatment for SAD is bright-light therapy, which requires a medical-grade device that shines 20 to l times brighter calorie-free than what these alarms provide. A severe case of DSPS requires a regimen prescribed by a sleep medico.

Finally, proceed in mind that a sunrise alarm clock might not be a practiced idea if yous sleep with a partner on a different schedule. Unless they’re blest with the gift of sleeping through anything, those accepted to sleeping in will take to get with the earlier program, clothing a sleep mask, or wake upwards before.

Information technology’due south hard to test lights without having them in hand, so we started out past picking clocks that met the post-obit criteria, with the virtually important ones upward top:

Good full general appearance:
You can’t aid but detect the device on your nightstand, so information technology’due south preferable to have something that can hold its ain in a well-kept bedroom. We set out to notice a dependable clock that about people would be happy to display on their nightstand.

Substantial weight:
Yous can swat an alarm clock effectually quite a bit as y’all’re half-consciously trying to hit the snooze button.

Unobtrusive time display:
Given that the all-time sleep happens in a dark room, it’s not helpful if the clock’s numbers are flashing in your face. We favored clocks that let y’all adjust the brightness of the numbers.

Pleasant alarm tones:
Although low-cal is the principal method of waking yous up, these clocks as well feature an audio alarm, which kicks in at the height of the light’s brightness. Some weeks y’all may simply feel like waking upwardly to the sound of waves crashing on a beach. And other times you may exist in a birds-in-the-forest sort of mood. Nosotros favored clocks with a multifariousness of sounds to choose from.

Backup alarm:
For those occasions when you ambitiously set the warning at five a.m. to become stuff done—only to deeply regret it when the alarm actually goes off—a second alarm tin bear witness useful for setting a more humane time.

Power-backup capabilities:
It’south a shame to miss an of import event (a job interview, a flight to a wedding) considering the power blows out. We wanted clocks that prevented this from happening.

Nosotros ended upward choosing four Philips models, likewise as the Lumie Bodyclock Active 250 and the hOmelabs Sunrise Warning Clock. Each model earned a spot on my nightstand for at to the lowest degree a 24-hour interval. I noted how I felt with each alarm in the morn, and I compared the clocks next in late-sunset fashion to appraise the dash of their colors. I also listened to each alarm tone and radio to evaluate the option and sound quality.

Our pick

The Philips Wake-Up Light HF3520 offers the best features at the most reasonable price. It’s the to the lowest degree expensive alarm we’ve found that offers a realistic, ruby-red-tinted dawn and dusk simulation, which feels more than natural and may piece of work better than white light at helping you experience less groggy. Information technology also offers thoughtful extras such as v alert tones, a good radio, and a backup alarm; plus, it looks sleeker and feels sturdier than similarly priced and cheaper models.

The HF3520 and Philips’southward two premium models, the SmartSleep HF3650 and HF3670 (our upgrade pick), are the merely Philips alarms that offering a red-light component in their simulation, and science suggests that this approach may be more than than a gimmick. A 2015 PLoS Biology study on mice suggests that the more than natural the light, the more effective information technology is at shifting the internal circadian clock. Humans aren’t mice, of grade, merely the concept is rational, said Dan Oren, Physician, associate adjunct professor of psychiatry at Yale University, in an interview.

In any instance, being a light sleeper, in my testing I’d wake up not also long after the low-cal show kicked in, and I did appreciate the warm ruby-red hue of this model over the simple orangish ane of the Philips HF3510, the clock that’s the next level down in the line. The feel was like enjoying skilful gelato every bit opposed to frozen yogurt—they’re both tasty, but the latter is missing a little something-something.

We liked waking upwardly to the red-infused sunrise of both the Philips HF3520 (left) and the Philips SmartSleep HF3670 better than we did the less-nuanced lights in the cheaper clocks.

I appreciated that red tone fifty-fifty more than, though, as it appeared in the faux sunset. (The dusk in the model the side by side level down looked more orange than red.) I liked the way it made my room await as I was getting set up for bed; at times, the consequence was even enough to entice me to shut down my laptop. As with simulated dawn, more research is needed to prove the benefits of a imitation sunset, but information technology’s reasonable to remember that it may assist you get on a better sleep cycle, said Oren. Any calorie-free at night can suppress melatonin, but dimmer, longer-wavelength lights (such every bit the ruby-red of the HF3520) suppress it less. So when you program a imitation sunset, you’re allowing your torso to feel sleepy as it naturally should—in turn, y’all go to bed earlier, you become more sleep, and ultimately you get upward more than easily when the fake dawn kicks in.

With the tap of a button, the clock can likewise work equally a lamp.

We like that the numbers on the clock dim when the room dims, just as with the SmartSleep. Darker rooms foster more restorative sleep. With the cheaper models, yous have to arrange the effulgence yourself. Our pick isn’t every bit brilliant as the SmartSleep, however—its maximum intensity is 300 lux as opposed to 315 lux (a measure of lite intensity equally picked up past your retina). Just that isn’t a large deal. “We don’t have any data that this small-scale difference would be noticeable,” explained Kathryn Roecklein, PhD, associate professor of psychology at the University of Pittsburgh, in an interview.

The speaker on the back of the Philips HF3520 sounds meliorate than those of the cheaper clocks nosotros tried, and simply as proficient as the one on Philips’s premium model.

For those days when you’re actually wiped out and you need the sound of an alarm to nudge you awake, the clock has five alarm tones you tin cull from: yoga-ish music with chirping birds, chirping just, chirping with a cuckoo, gentle piano music, and ocean waves with seagulls. The Philips model that’s the adjacent level downwardly has merely three choices (piano music, plain chirping, and chirping with the cuckoo), and non the best of the bunch, in my opinion. There’s also a radio, which sounds equally good every bit on our upgrade pick, the Philips Somneo, and can serve as an alarm tone besides. If these sounds don’t go you upwardly, yous can besides set a backup alarm. To snooze an alarm, all you take to do is touch on the clock anywhere—a convenience that’due south unique to this model.

The orb-shaped Philips HF3520 (left) has a simpler blueprint, just still offers plenty of features. (On the right is the Philips Somneo, our previous upgrade choice.)

The glossy orb pattern is arguably as attractive as that of the more expensive Philips models, and it’due south definitely an upgrade from the plasticky designs of the lower-end choices. What’s more, its shape (a sort of a sideways cone) and weight keep it from toppling over.

This clock officially retails for $140, about $60 less than the top-tier Philips models. Just expect around the major retailers, including Amazon, and chances are good that you’ll find it discounted to around $100 or less. That’s a bully deal, especially when you consider that the light-simulation part of the ii clocks is substantially the aforementioned. This clock is missing certain bells and whistles of the premium model—a phone charger, an aux cable and port to play music from your phone over the alarm’s speaker, a midnight light, and actress sounds—but we didn’t miss them enough to exist willing to pay $60 to $100 extra for them.

The solid, orb-like shape of the HF3520 made it hard to lift away from the nightstand when I was dusting. Although the rear extension makes information technology more stable, that also means you can’t align the clock against a wall. Nosotros preferred the doughnut-like shape and flattened back of the Philips Somneo.

Equally with all Philips models, the LED in the HF3520 tin’t be replaced when information technology goes out, so yous’ll have to supersede the entire clock (unless the LED fizzles earlier the ii-year warranty is up). Yet, every bit Philips’due south product development team wrote to the states, the clocks are “tested to last for vii years with regular utilize.” One Wirecutter colleague has used hers for half-dozen years, and it’south still working.

Upgrade selection

Overall, our wake-up experience with the Bluetooth-continued Philips SmartSleep HF3670 felt no different from the ane we had with our main pick. But if you like the convenience of programming your alarms via an intuitive app, setting multiple alarms during the week (including a very loud, very bright get-upward-or-else ane), customizing your sunrise themes, and using the clock as a calming tool for falling comatose, you may detect the Philips SmartSleep HF3670 to be worth the extra cost. It as well offers some other special features, similar temperature, humidity and light sensors, and the power to log your sleep and wake up times in the app, only these are merely nice-to-haves. (The SmartSleep HF3670 is the updated model of our previous upgrade pick, the Somneo HF3650.)

The SmartSleep’s SleepMapper app makes navigating the clock’s functions intuitive. With information technology, you lot can program wake-up alarms for every day of the week (equally opposed to just ii in the HF3520) and designate wind-down times, along with corresponding brightness levels, alarm sounds, radio stations, and the volume. You can also do all this directly with the buttons on the clock, simply that’s a lot of settings and a lot of buttons, which can get frustrating.

The SleepMapper app will ask yous to create an business relationship to apply information technology, but it’southward not required. The privacy policy says the app does collect data about how you employ the SmartSleep clock (for example, your warning settings and tones) and other information (like sensor readings and Wi-Fi data). Philips states that the app volition ask for your consent before this information is collected, and that the information may be used for sleep-related research. You should review the app’south privacy policy for more than information.

Besides 3 actress alarm sounds (think current of air chimes and yoga music), college maximum brightness (315 instead of simply 310 lux), and the added bister nuances in the light, you can choose from four sun “themes,” such every bit a pink “Caribbean” sunrise versus the frostier “Nordic” one. Honestly, I was besides sleepy to appreciate any of the extras above, but the so-called Power WakeUp warning commands attention. For the mornings you admittedly must be upwards by a sure time (like for a 4 a.m. flight), y’all can programme information technology to go off after your regular alert. When your tough-love moment arrives, the device flashes urgently like risk lights and emits a sound like a car that won’t start— right next to your bed. After turning in at ii a.1000. 1 nighttime, I pressed snooze iii times in the forenoon, just the noxious noise finally sent my heart racing and jolted me up from bed. What can I say? It works.

If y’all need assist decompressing at dark, the Philips HF 3670’southward upgraded wind-down feature provides a benefit that our main pick’s sunset doesn’t. Every bit the calorie-free dims gradually according to your set up time interval, over the form of, say, fifteen or thirty minutes, you can choose from seven “wind-down” programs to go with information technology, complete with animate exercises and relaxation sounds. For three days, I programmed ten minutes of ocean waves before bed—and I always fell comatose earlier it stopped. Of course, you might not be into this sort of thing, or y’all could simply pair the sunset feature on our principal choice with white-racket motorcar, slumber-tracking app, or meditation app. Just we appreciate the virtue of a streamlined sleep tool.

The Philips HF3670 has sensors in the back to discover your room’s temperature too equally its humidity, light, and noise levels. (Don’t worry: It doesn’t actually heed in; it just reads decibel changes.) You can cheque the app to discover out whether you need to make any changes appropriate for sleep. My room was also brilliant until I close off the lights. Information technology was likewise besides dry out, too noisy (considering of my noisy heating unit), and likewise warm. I haven’t yet tested the accuracy of the sensors’ readings, only they seemed generally on the mark—yous just demand to walk into my bedroom to know information technology. More helpful are the solutions the clock offers, like its calming wind-downwardly sounds that mask the racket I endure from my heating unit.

The HF 3670 also has a USB charging port, an on-demand nightlight, the ability to record your wake and sleep times in the app, an easier-to-maneuver donut shape, and an arguably more stylish look. You also tin tape your bedtime and wake time by borer a push button in the app. We considered these features to be “prissy-to-haves” merely not on their own worthy of the higher price.

hOmeLabs Sunrise Alarm Clock

A no-frills wake-up calorie-free

This sunrise alert’s low-cal simulation isn’t as soothing or radiant equally that of more than expensive wake-up lights, but its alarm sounds, dimming capabilities, and radio make it improve than some models that price twice as much.

If you lot’re curious how a wake-up light might help but you’re not set up to bet a lot of money on it, the hOmelabs Sunrise Warning Clock may be worth a try. The white lite it uses for dawn and dusk feels less soothing than the ruddy calorie-free of the Philips offerings. And its flyweight feel, plasticky appearance, and tinny sound make it seem cheap. But it comes with features you lot typically find in high-cease clocks, and that makes this model the best budget pick.

Rather than simulating dawn or dusk, its white calorie-free simply grows from dim to bright within a 30-minute window—no fancy color nuances, and with a less gradual alter than on our other picks. Even at its elevation, the light doesn’t quite fill the room—information technology’s only 130 lux, compared with our main pick’due south 300 and the entry-level Philips’s 200. (We found similar flaws in the other under-$50 wake-upwards lights nosotros tried.) You can also pair the low-cal with one of its vii alarm tones (virtually as many as on the Somneo at a fraction of the cost), including the radio. The radio and its alert rendition of Pachelbel’s Canon sounds tinny compared with our more than-expensive picks, and the time display is less subtle, but set information technology to the bird chirping and ocean waves and plough the brandish off, and y’all should be fine. Unlike with the Philips clocks, both the light and the audio stop (instead of just the sound) when you hit snooze; at least i online reviewer disliked this, though my hubby actually preferred it. I woke before long later the alert, but presumably deeper sleepers have noted that the sound alert shuts off also before long. On the plus side, you lot can use the clock as a reading light and programme it to dim as you wind downward and go to bed. Just for fun, you can also conform it to glow in one of six different Gatorade-similar colors in the nighttime—only just the white calorie-free works as an alarm low-cal.

Our budget selection from hOmelabs can work as lamp too.

With the included bombardment, the hOmelabs alarm goes off even if the power conks out. In the Philips line, only the far more expensive Philips Somneo and HF3520 do that, and none of that company’s midtier alert clocks we tried betwixt $50 and $100 offer fill-in power. A rubberized foundation keeps the hOmelabs clock from slipping off the nightstand despite its low-cal weight, and it comes with a 30-calendar month warranty if you register the product—the coverage is six months longer than that of the other models we tried.

Compared with the many other depression-priced sunrise alarms that look the same on Amazon, the hOmelabs Sunrise Alarm Clock—with more than four,800 reviews at this writing—stood out. hOmelabs customer service helped us resolve a battery question with a quick call, and responded to an emailed question nearly the clock’s lux value inside a few days.

Although information technology took a couple of weeks before nosotros could get more data about hOmelabs (it turns out that a holding company is behind hOmelabs), we decided we were okay with that, given that the clock costs less than a date night at the movies and, if yous buy it on Amazon and determine y’all don’t like information technology, you tin can return it within xxx days. Since this guide first published, in late 2018, I’ve been long-term testing this clock in my son’s room, and it has held upward well so far.

Flip the Casper Glow Light to turn information technology on and off, twist information technology to adapt the light, and jerk it to turn on the night-light.

Video: Sarah Kobos

In Jan 2019, Casper introduced the Glow Light, a lighting device that doesn’t quite fit into whatsoever category—the visitor simply calls the 3-by-5-inch cylinder “a magical light for better slumber.” Nosotros found information technology fun and piece of cake to use, just overpriced.

As with a sunrise warning clock, you tin can plan the Glow Light to burnish and dim gradually to ease y’all into waking up and going to bed, but different our existing picks it has no clock and no audio alert. Similar to the Philips Hue Go, which is essentially an ambient-lighting device, the Glow Light is portable and programmable via a smartphone just provides far fewer options and can’t connect to other smart devices, such every bit Alexa-based devices.

Notwithstanding, nosotros dear that the Glow Light is pleasingly intuitive—and it beats deciphering an teaching book and fumbling for buttons in the night. Twist it to adjust its brightness. Flip information technology to turn it off (or on again). Wiggle it to summon a night-calorie-free. Unlike the Philips Hue Become, which looks like a bowl and begs to be held with 2 hands, the Glow Light is shaped to grab and become, which fabricated it and then useful in my household. Come up dusk, I’d identify it on my son’s nightstand so that 30 minutes of reading became 30 minutes until the light went out. Later I’d movement it to my living room, where I similar to read earlier bed, and then onto my nightstand for waking me up in silence the next morning. Its lantern-similar nighttime-light came in handy the time my son yelled for me from his room at 4 a.thousand., likewise equally when he needed a lamp for his pillow fort. Once yous live with the Glow Lite, you might find other uses. Jeff Chapin, Casper founder and product designer, told me that new moms accept used it for center-of-the-night feedings. If Casper’s simple tactile arroyo appeals to you, and you have a flexible budget, the Glow Lite may be worth trying (information technology has a thirty-night gratuitous trial).

Yet, assuming you need an warning because yous have a difficult time getting out of bed, you’d get more for your coin with a defended clock. (I get up early and easily, so when the Glow Calorie-free brightened, I woke upwardly and enjoyed the silence. Only my husband, a heavy sleeper, consistently slept through it.)

If you lot tin wake upward with just a light, using a smart bulb (see below) or fifty-fifty the Philips Hue Go would be more cost constructive. The Hue Go, which nosotros also tried, currently costs around $80, merely you need to purchase a Hue Bridge (to connect to your router), which means paying another $60 to take total reward of it. That brings it up to the Glow Light’due south price range but allows you lot to accept reward of the Hue Go’s additional features as well as to add smart bulbs to the rest of your business firm (see below).

You tin can find a few dawn-simulating apps on iTunes and Google Play, but they tend to garner mixed reviews and emit meager lite compared with a clock or other dedicated device (run into below). As John Hanifin, PhD, banana professor of neurology at Thomas Jefferson University in Philadelphia, explained in an interview, information technology’s preferable to accept a “bedroom-filling” light—and that’s hard for these apps to do, though on the nights I tried them (and when I set them before than I’d comfortably wake up), they did the job of nudging me awake. Nosotros haven’t constitute one all the same that we’d recommend (peculiarly since the costless versions oft come up with also many ads).

If you lot want to experiment with your smart-habitation devices and lighting, you could attempt a smart seedling (such every bit from Philips Hue or LIFX), said Grant Clauser, Wirecutter’s senior editor covering the smart-habitation beat out. Equally with the not-clock wake-up lights, this approach works best if you’re confident virtually getting up without the help of a only-in-case warning tone (though yous can utilize a regular alarm clock or your phone as backup, of course). LIFX’s bulbs tin can even mimic the nuanced colors of the ascent and setting sun. You tin can employ a smart bulb with a regular lamp and control information technology with an app or smart speaker such as an Amazon Echo or Google Nest. The price range for smart color-adjustable bulbs lies betwixt $35 and $50; white ones are typically under $20. Liam McCabe, Wirecutter’due south senior author for appliances, uses a LIFX bulb and likes that information technology doesn’t take upwards his limited nightstand space and helps him feel “similar I’m waking up on my ain rather than being jolted awake.” Although he has overslept a few times, he has three backups on the mornings he can’t hazard that: “my wife’south warning, my daughter crying, and my wife shaking me awake when all else fails.”

iHome Zenergy Dream Mini: Nosotros beloved this clock’s sound quality and solid, compact feel, merely it was designed more for people who have trouble falling asleep than for those who have bug waking upward. Like the Philips upgrade selection, the iHome offers an extensive wind-down program, notwithstanding costs about a quarter of the price. Y’all can customize a range of relaxation routines using a combination of xvi sounds (melodies, nature sounds, heartbeat, a “4-vii-viii” breathing meditation, and more) and 10 light options (including various colors, pulse, and off). Pressing the “Zenergy” button calls upward your routine to help yous sleep. Nonetheless, with a lite that’s dimmer than whatsoever of the others in this guide, the iHome isn’t a very good wake-up clock.

La Crosse Technology C85135 Mood Calorie-free and Nature Sound Alarm Clock: This clock is around the aforementioned cost every bit our budget pick, but information technology doesn’t give off as much light and its customer service isn’t as responsive. Most of the La Crosse’southward attributes are more dainty-to-haves than wake-upwards essentials, including its conspicuously labeled, intuitive-to-set buttons and a USB port (and then you can charge your phone and listen to a personal playlist). It’s handy that the display shows the appointment, too. Unfortunately, the light isn’t and so much a gradually swelling sunrise as information technology is a lamp with a brightening switch that turns itself on in stilted increments. The sound warning—a choice of five not-always-calming nature options (bounding main waves merely also a thunderstorm), plus a buzzer—grows quite loud, but the highest brightness level barely fills the corner of the room, permit lone the whole space. In that location are seven colour options to play with but the sunrise works only with white.

La Crosse Engineering science C80994 Soluna Lite Alert Clock: This clock is a chip more expensive than our budget choice and the C85135 Mood Calorie-free, but whether that extra money buys you an enhanced wake-upwardly experience is debatable. Instead of soothing rain, ocean waves, or chirping birds, the Soluna offers only 1 alert selection: a tinny-sounding melody that evokes a current of air-up music box. It gets frighteningly louder for five long minutes following the designated wake-upwardly fourth dimension, unless y’all close it off. As with all the nether-$100 non-Philips sunrise alarm clocks we tested, the calorie-free’due south maximum brightness levels aren’t listed. (Unlike hOmelabs, La Crosse didn’t reply to our emails). The wake-up light doesn’t mimic the colors of sunrise, despite the clock’s 20 “mood-light” options (including scarlet and orange), nor does it fill the room. A simulated-dusk and guided-animate light are among the low-cal-mode options, but because each puzzlingly includes a distracting blueish and purple, we didn’t necessarily find them relaxing or sleep inducing.

Lexon Miami Sunrise Simulator Alarm Clock: The wake-upwards feature on this elegant half-orb resembles the Philips clocks more than the other nether-$100 options in this guide. Instead of a one-dimensional white, its sunrise emerges with a pale orange, though its hue is less saturated than that of the Philips. Instead of reaching its brightest acme in awkwardly distinct “steps,” the lite swells gracefully and smoothly to a vivid white. Vi pleasant tones (pianoforte music, a babbling beck) sound off when the light is at its brightest. The clock’s biggest drawback, though, is that the light isn’t as robust as that of all the Philips options, which is essential to helping you feel awake. As well, snoozing and shutting off the alarm tin be a challenge—the “buttons” are in the back and not raised, making them difficult to navigate when y’all’re half-awake.

Lumie Bodyclock Active 250: If Lumie’due south models sold more widely in the United states, information technology would be Philips’southward competitor. Nosotros like how seriously this company takes its science, and how it shares its findings in dawn-simulation research. Rather than using an LED, the Bodyclock Active 250 employs a bulb (included) that at the designated time emits an estimated maximum 500 lux at 12 inches away. In our tests, the lite fabricated the clock feel hot, an issue I didn’t feel with whatsoever of the Philips models. On the plus side, this clock also has power backup, a simulated sunset with relaxing sounds, and five alarm tones, plus a radio. But considering the price (typically $140) and its express accessibility in the U.s., we concluded that the Philips HF3520 was a better pick for most people, at least in the short run (see Flaws only non dealbreakers).

Philips SmartSleep Sleep and Wake-Up Light HF3650: Previously called the Somneo, this model is essentially our electric current upgrade pick, the HF3670, but without Bluetooth connectivity (and thus the ability to control the clock’s settings from an app.) It has one less wake-up sound and relaxation audio than the HF3670 and only one sunrise to choose from (every bit opposed to four). Because the HF3650 typically costs the same as the HF 3670, our upgrade selection, when the latter is on sale, but has fewer features, we think you’re amend off going with the HF3670.

Philips Wake-Upward Light HF3510: This model is one level below our choice in the Philips lineup. Information technology’s a fine wake-up low-cal, with the aforementioned shape as the HF3520, simply it has a matte finish that doesn’t wait as luxe. It as well omits a second warning, offers but three natural wake-up sounds (piano music, chirping with cuckoo, and plain chirping), and lacks the soothing ruby-red in its simulated orange-dominant dawn. At $100 currently, this model’s cost is similar to our option’s frequent on-auction toll, yet it falls brusk.

Philips Wake-Upwards Lite HF3500: Philips’south entry-level clock looks much sleeker than our budget pick and the La Crosse models. Its sunrise also starts off with more warmth and brightens gradually to 200 lux (70 more than that of our budget option, the hOmeLabs Sunrise Alarm Clock) to more effectively fill a room. However, at about $50, it’s ordinarily more than twice the toll of the hOmeLabs notwithstanding has fewer features. The biggest dealbreaker for usa is that instead of multiple alarm tones, it offers just a “gentle” beep, which, in fact, sounds nigh as soothing as being in a infirmary. As with the other under-$100 models listed in this guide (except for the Zenergy), it felt flimsy, besides.
