Waking up to a blaring smartphone alarm in a pitch-black room doesn't just get your morning off to a bad start — it can trigger a state of grogginess and confusion known as sleep inertia. When we first tested the Philips SmartSleep Wake-Up Light back in 2021, we praised its ability to cure this post-sleep fog with a gentle artificial dawn. But how does it hold up years later in a market flooded with app-connected silent alarm clocks and smart lamps? After years of continuous testing, the verdict is clear: sometimes, keeping your bedroom free of apps and monthly subscriptions is exactly what your sleep hygiene needs.
The 5-year update: Durability and the "dumb tech" advantage
When we first tested the Philips SmartSleep Wake-Up Light years ago, we noted its lack of Wi-Fi and app connectivity felt like a missed opportunity. Today, in an era of app fatigue and digital clutter, its fully manual interface is actually one of its greatest strengths.
Over years of long-term testing, the built-in LED bulb (which is non-replaceable) has shown zero signs of dimming or color degradation. The light still transitions beautifully through rich red, orange, and yellow hues. Keeping your smartphone out of the bedroom is a cornerstone of modern sleep hygiene, and this clock allows you to set your schedule, adjust settings, and wind down without ever looking at a screen.
Waking up with the Philips SmartSleep
The Philips SmartSleep Wake-Up Light might take up quite a bit of space on a smaller nightstand. It's 7.5 inches high and 7.8 inches wide. It weighs 2.5 pounds and is a little on the bulky side, but the anti-slip rubbery bottom will make sure it stays in place. The front of the device is a smooth, glossy sphere equipped with LEDs that glow evenly, and the back is shaped like a glossy cone with a built-in speaker. Two different alarms can be personalized with five nature sounds and a choice of 20 brightness levels. There are a few side buttons located on the rim of the device to adjust brightness, volume, and FM radio.
The Philips SmartSleep is also meant to be used as a bedside lamp that can be switched on and off by pressing the corresponding side button. The smart snooze lasts only up to nine minutes and can be activated with a slight tap. The time display can be set to a 12- or 24-hour clock. Users can also adjust their wake-up profile to gradually brighten for 20 to 40 minutes (30 minutes by default).
Setting up my Philips wake-up lamp was easy with its user-friendly instructions. The guide provides step-by-step, illustrated instructions that I was able to follow as I configured the device. I set my weekly wake-up alarm by pressing through the soft-touch controls to select my preferred light intensity, sound level, and wake-up time. I set it to wake me up gradually over 30 minutes to the gentle sounds of "Nepal bowls." Waking up to the serene sunrise simulation with beautiful, refreshing orange-and-yellow hues and the uplifting sounds was such a pleasant experience. The Philips SmartSleep mimics one of the most invigorating and natural sunrises that I have seen in a wake-up lamp. I snoozed my alarm by tapping softly on the front of the device. (I suggest tapping on it very slightly, as too much force might cause damage to the unit.) The alarm sound stops, but the light stays on for up to nine minutes.
The Philips sunrise lamp also allows users to adjust the time display contrast — a great feature for total darkness. The display brightness automatically increases according to the amount of light in the bedroom, and it automatically dims as the room gets dark. I recommend shutting it off completely during the night. Looking at the time when you're trying to relax can cause unnecessary anxiety. Users can also create a fall-asleep profile that simulates a natural sunset. The lamp gradually dims its rich orange-and-yellow hues for five minutes to an hour. I set my wind-down profile to dim for 30 minutes with the FM radio on. The light and sound faded softly as I drifted off to sleep. After using my Philips wake-up lamp for just a few nights, I noticed that I was waking up in a much better mood and I didn't feel groggy. I felt energized by the refreshing sunrise and sounds that flooded my bedroom in the morning and sleep inertia was no longer an issue.
Cons to consider
This device is also larger than the typical alarm clock, and it's somewhat heavy to move around — not ideal for small bedside tables with limited space. The buttons on the rim that control brightness and volume are slightly difficult to navigate because of where they're located. I often struggled to find the right buttons, sometimes unintentionally increasing the volume when I meant to increase brightness.
How the Philips SmartSleep Wake-Up Light compares to the modern market
The sleep tech space has exploded recently, meaning the Philips SleepSmart Wake-Up Light now faces some stiff competition. Here's how it holds up:
| Best for | Standout feature | Sunrise transition quality | Price | |
| Philips SmartSleep Wake-up Light | Light-sensitive sleepers who need a genuinely bright, gradual wake-up cue. | Unmatched dawn simulation with 20 distinct brightness levels. | Excellent: Smooth and imperceptible. | $$$$ |
| Hatch Restore 3 | Habit-builders who want guided sleep and wake routines in one device. | Extensive library of white noise, soundscapes, and customizable light hues. | Very good: Gentle, though unlocking all features requires a subscription. | $$$$ |
| Loftie Lamp | Design enthusiasts who want a wake-up light that doubles as a bedside reading lamp. | A sleek, modern aesthetic that doesn't look like a medical device. | Good: Soft and calming, but less powerful than the Philips. | $$$$ |
| Dekala Sunrise Alarm Clock | First time sunrise alarm users who want to try the format without over-investing. | A solid lineup of basic alarm, sound, and color options for a fraction of the price. | Fair: Functional, but the light steps are less nuanced than premium models. | $ |
The bottom line
Overall, the Philips SmartSleep Wake-up Light is effective in reducing the awful effects of sleep inertia. Philips designers say they built this device based on research and science. As a sleep researcher, I always love to see products that are backed by science and contribute to healthy sleep habits. Ultimately, I recommend this device to anyone looking to improve how they fall asleep and wake up.
