How this page is funded: we earn a commission if you buy through the links below, at no extra cost to you. As an Amazon Associate we earn from qualifying purchases. It does not change which products we pick or the order they appear in. Full disclosure.
How these picks were made: by comparing published specifications and clearly-credited public reporting. We do not run a laboratory, we have not measured these products, and we do not claim to have slept with them. Here is exactly how we choose.
Short answer: buy the Philips SmartSleep HF3520 if you want a wake-up light and nothing else - no account, no app, no monthly fee, and 20 light-intensity steps so you can actually find a display brightness you can sleep next to. Buy the Hatch Restore 3 if you want the whole bedtime routine in one device - wind-down content, a sound library, app scheduling - and you are comfortable that the best of the content sits behind a Hatch+ subscription. The light itself is good on both. What you are really choosing between is an appliance and a platform.
This is the comparison people type, so it is worth saying plainly what the real difference is, because it is not the sunrise. Both devices ramp light before your alarm, both do it competently, and if the only thing you want is to stop being detonated awake by a phone alarm, either one works. The divergence is in everything around the light.
The comparison
| Philips SmartSleep HF3520 | Hatch Restore 3 | |
|---|---|---|
| Sunrise | Colored sunrise simulation before the alarm | Roughly 30-minute ramp, deep orange to bright white |
| Light control | 20 intensity settings | App-set brightness and color path |
| Account required | None | Yes - the app is required for setup |
| Subscription | None, ever | Hatch+ gates the premium sound and wind-down library |
| Sound | Natural wake-up sounds plus FM radio | Built-in sound library plus alarm tones |
| Wind-down content | No | Yes - this is the main reason to pay for it |
| Doubles as a sound machine | Not really | Yes |
| Fails if your phone dies | No. It is a dial | Scheduling changes do, yes |
| Best for | Light quality with zero ongoing commitment | One device running the whole evening and morning |

The subscription question, with the actual details
This is where most of the resentment in this category lives, so here is what is genuinely behind the paywall rather than a vague warning. Hatch publishes the split itself: its own support article lists what you get free and what Hatch+ adds, and the membership page carries current pricing. A separate support article covers which sounds you can wake up to.
The honest summary: the device works without a subscription. The sunrise, the alarm and a base set of sounds are yours. What Hatch+ buys is the depth - the meditations, sleep stories, the larger sound library, the seasonal content. If you will use those, it is a content subscription and should be judged like one. If you will not, you are paying premium hardware prices for a light.
We went into this in more detail on the Hatch sound library page and the broader subscription-or-not comparison, because it is the single most common regret in this category.
On light quality, the gap is smaller than the price
Both are at the top of the consumer category, and independent measurement is the only honest way to separate them. Light-meter comparisons exist for this category - those measurements are theirs, not ours - and Tom’s Guide tests the field, as does Sleep Foundation. The consistent pattern across that reporting is that the premium units separate from the budget ones clearly, and separate from each other only slightly.
Which means light quality is probably not your deciding spec between these two. Two things that genuinely do differ:
Display dimming. Philips publishes 20 intensity settings, and that granularity matters more than it sounds. A bedside display you cannot get dim enough is a nightly light-exposure problem, and the 2022 PLOS Biology recommendations are strict about darkness at night for a reason. Hatch dims too, but through the app.
Light spread. A broad diffused source lights the room; a narrow one lights what it is pointed at. For a side sleeper facing away, room-filling beats bright - which is the whole argument on the side-sleeper page.
How each one fails
A fairer way to choose between two good products is to ask how they go wrong.
The Philips fails by being inflexible. Manual scheduling means changing a weekday alarm for a weekend is a physical operation. The sound library is small and dated. If you want a different wake-up schedule every day, you will be turning a dial every day.
The Hatch fails by being dependent. No phone, no changes. An app update can move controls you had learned. And the subscription is a recurring decision rather than a one-time one - the thing you bought gets quietly less capable the moment you stop paying, which is a worse feeling than never having had the content.
Neither failure mode is disqualifying. They are just different kinds of annoyance, and people have strong instincts about which one they would rather live with.
The third option both reviews tend to skip
If the ramp is what you care about - the duration of the sunrise, and having a matching sunset - neither of these is the specialist. Lumie publishes 15 to 90 minute sunrise and sunset durations on the Bodyclock Shine 300, with a light-sensitive auto-dimming display, which is a narrower and better-aimed set of specs than either mainstream unit offers.
The trade is availability and polish: it is a UK light-therapy manufacturer with patchier US distribution and a dated interface, and there is no app. We wrote up the Lumie separately if that sounds like your priority.
The verdict
For most buyers: the Philips. It does the thing you came for, it has no ongoing cost, nothing about it can be changed by a software update, and its display dimming is the best-published in the group. It is the lower-regret purchase.
Choose the Hatch when the sunrise is genuinely secondary - when what you want is one object that runs a wind-down, plays sound all night, and wakes you up, and when a content subscription is a thing you are happy to own. Under those terms it is the better device and the extra money is going somewhere real.
And if you have slept through a light alarm before, stop comparing lights. Neither of these will reach you, and the heavy-sleeper page is the one to read instead.

Our top pick · Sunrise quality with no app and no subscription
1. Philips SmartSleep Wake-Up Light HF3520
The reference sunrise. No account, no app, no monthly fee - a dial, twenty brightness steps, and a light that ramps properly.
- Light settings:
- 20 intensity levels
- Sunrise:
- Colored sunrise simulation before the alarm
- Sound:
- Natural wake-up sounds plus FM radio
- Account:
- None required
What it gets right
- Nothing to sign up for and nothing to update - it is an appliance
- Twenty brightness steps means you can actually find a comfortable display level
- Long-standing design with a well-understood service life
Where it falls short
- No app, so scheduling is manual
- The sound library is small and dated
- Larger footprint than the smart units
Skip it if: You want a sound machine and a sunrise in one device. This is a light first and foremost.
Pick 2 · One device for the whole bedtime routine
2. Hatch Restore 3
The most complete bedside device of the group - sunrise, wind-down, sound library and alarms in one - and the only one with a subscription attached.
- Sunrise:
- Gradual ramp beginning around 30 minutes before the alarm
- Color path:
- Deep orange warming to bright white
- Sound:
- Built-in sound library plus alarm tones
- App:
- Required for setup; premium library is subscription-gated
What it gets right
- Sunrise, wind-down and sound machine in a single footprint
- The app makes complex schedules genuinely easy to set
- The display dims properly, unlike most clock radios
Where it falls short
- The best sound content sits behind a subscription
- App dependency: no phone, no changes
- Most expensive way to buy a sunrise
Skip it if: You resent subscriptions. The Philips does the light half with no account at all.
Pick 3 · Long, slow sunrises and a proper sunset
3. Lumie Bodyclock Shine 300
The specialist's pick: adjustable ramp duration in both directions, from a manufacturer that only makes light-therapy devices.
- Sunrise:
- Adjustable duration, short through extended
- Sunset:
- Matching fade-to-dark on the same schedule
- Sound:
- Wake and sleep sounds plus radio
- Specialism:
- Light-therapy manufacturer
What it gets right
- The sunset fade is as well implemented as the sunrise, which is rare
- Duration control matters more than peak brightness for light sleepers
- No subscription
Where it falls short
- Priced with the premium units without the smart features
- US availability is patchier than Philips or Hatch
- Dated interface
Skip it if: You want app scheduling. This is a well-made physical device with physical controls.
Questions people actually ask
Is the Hatch Restore better than the Philips SmartSleep?
Not as a wake-up light. Both ramp light competently and the gap in light quality is smaller than the price gap. The Hatch is better if you want wind-down content, a sound library and app scheduling in the same device; the Philips is better if you want 20 light-intensity steps, no account and no subscription.
Does the Hatch Restore require a subscription?
The device works without one - the sunrise, the alarm and a base set of sounds are included. Hatch+ unlocks the deeper content: meditations, sleep stories and the larger sound library. Hatch publishes the free-versus-paid split in its own support documentation, so judge it as a content subscription rather than a hidden fee.
Does the Philips SmartSleep need an app?
No, and that is the main reason to buy it. There is no account, no app and no subscription - scheduling is done on the device with physical controls. The trade-off is that changing alarms is a manual operation every time, which is tedious if your schedule varies day to day.
Which one is better for a dark bedroom?
The Philips, on published specs: 20 light-intensity settings give you fine control over how dim the display gets, and a bedside display you cannot dim enough is a nightly light-exposure problem. The Hatch dims as well, but through the app rather than a dial.
Which has better sound, the Hatch or the Philips?
The Hatch, without much argument. It has a real sound library and can act as a sound machine all night. The Philips offers a small set of natural wake-up sounds plus FM radio, and it is a light first - if you want one device to do both jobs, that is the Hatch's case.
Is there a better option than either of these?
If the ramp itself is your priority, yes. Lumie publishes 15 to 90 minute adjustable sunrise and sunset durations on the Bodyclock Shine 300, with a light-sensitive auto-dimming display - narrower specs, better aimed. The costs are patchier US availability, a dated interface and no app.
