Best Overall:Philips SmartSleep Wake-Up Light4.9 Buy on AmazonBuy on Best BuyBuy on WalmartPhilips HF3520 Light Therapy Alarm Clock Review
The idea of a gentle wake-up alarm clock still has many skeptics, but the Philips HF3520 is designed to emulate the sunrise in the morning. The hope behind the Philips design is that the brain is stimulated to the point that it's telling your body “it's time to get up,"which allows for a much more natural morning experience. Gone are the days of the abrupt wake-up with blaring beeps and snooze buttons. The colored display offers a natural light experience along with five calming wake-up sounds.
If you want to combine the best of both gentle wake-up and old-school function, there's FM radio capability and a tap-to-snooze alarm clock, just in case. Additionally, the bedside light dims and it sounds gently to help you go to sleep, emulating a more natural way to enter REM sleep. With 20 total brightness settings, the lighting begins to gradually increase 20 to 40 minutes before your selected alarm time.The 7 Best Wake-Up Light Therapy Alarm Clocks of 2021
Best Smart:Lenovo Smart Clock Essential3.9 Buy on Best BuyBuy on WalmartBuy on B&H Photo VideoLenovo Smart Clock Essential Review
The Lenovo Smart Clock Essential is a Google Assistant-enabled alarm clock with a built-in speaker and nightlight. Design-wise, the compact wedge-like shape, bright LCD display, and textured fabric covering come together to provide a more contemporary and attractive spin on an old-fashioned digital alarm clock.
One drawback of the design is the limited control over the display brightness. You can request reduced intensity with a voice prompt or by enabling night mode, but our product tester found limited success with both. The nightlight, though, is more straightforward to control with a voice command or manually.
In most respects, the reliance on a smart assistant makes using this alarm clock easier and more desirable than a non-smart device. If you prefer, you'll never have to manually input an alarm, and preparing for daily routines—by asking for forecast information, changing the thermostat or lights, and getting calendar or traffic updates—is as easy as saying, “Good morning,” or your command of choice.
You can also use this smart clock as a speaker for streaming podcasts or playlists from Spotify, YouTube, and Pandora, and controlling other Google Assistant/Google Home-compatible devices throughout your home within a reliable 16-foot operating range. While it's not the most advanced smart alarm clock on the market, it's pretty clever for a very reasonable $25.
"Compared to a basic digital alarm clock, this device offers a touch of above-average functionality at a budget-friendly price."— Yoona Wagener, Product Tester

Fortunately, the display can be dimmed for added comfort, so they aren't too bright.
While the Travelwey is powered by an AC outlet, two AAA batteries provide limited power backup. If power is out, the display goes blank to conserve battery and maintain existing alarm settings. To see the current time, just tap the snooze button and you'll get 2 seconds of time shown.

The best alarm clock is the Philips SmartSleep HF3520 (view on Amazon). It's one of the best wake-up lights on the market, letting your body wake up in a peaceful, natural way withotu needing to blare an alarm. For a more traditional alarm clock, we like the Brandstand CubieTime (view on Amazon). It's not much of a looker, but it has a simple interface, backup batteries, and offers additional charging options.
What to Look for in an Alarm Clock
Display brightness and color - If you have trouble sleeping in a room with a lot of light, look for an alarm clock that has adjustable brightness controls or a dim display by default. Also keep in mind that too much blue light can make your body think that it's already morning.
Connectivity - If you're looking for a basic alarm clock, connectivity doesn't matter. But if you want a little more out of your device, some of them can stream music via Bluetooth and even connect to the Internet.
Alarm method - There's no reason to settle for a basic buzzer, unless that's what you really want. For heavy sleepers, some alarm clocks are equipped with flashing lights and loud noises, while others are designed to wake you up gently with simulated sunrises and nature sounds. If you're guilty of snoozing, you can even find ones that won't stop until you physically get out of bed.
