Choose if	You want a dawn-style alarm you set with buttons, with no app, Wi-Fi or subscription.	You want a sunrise alarm and sleep sounds in one clock, and you're fine setting it up in an app.
Main trade-off	It has no phone control or streaming, and the clock memory lasts only 4 to 8 hours in a power cut.	It requires Wi-Fi and an app, and Hatch publishes no lux or color temperature for the light.
Key specifications	Sunrise: 30 minutes by default, adjustable to 20, 25, 35 or 40 minutes. Light moves from red through orange to yellow. Light output: 20 levels, about 1 to 300 lux at 45 cm (17.7 in). Color about 1500 K to 2800 K, UV-free. Sounds: Five natural sounds (Forest Birds, Buddha, Yoga, Ocean Waves, Nepal Bowls) or FM radio (87.5 to 108.0 MHz). The sound rises to your chosen volume within about 1.5 minutes. Alarms and snooze: Two alarms. Tap the top to snooze for 9 minutes. A fall-asleep dimming timer of 5 to 60 minutes. App and connectivity: No app control and no smartphone audio listed. No Wi-Fi or Bluetooth listed. Doesn't charge a phone. Power: Adapter takes 100 to 240 V AC and outputs 24 V DC. Main unit rated 12 W (the product page says 16.5 W). Standby is under 0.5 W with the display at maximum and under 0.25 W with it off. Power cut: Clock time is kept for up to 8 hours (the product page says 4 to 8 hours). Longer and you reset it. Display: Four brightness levels plus off. It brightens on its own when the room is bright. Size and weight: Manual: about 20 x 20 x 15 cm and 0.76 kg. Product page: 19.2 x 19.9 x 14.6 cm and 730 g.

Warranty and returns: Two-year warranty. 90-day money-back guarantee with mailed return and refund by check.	Sunrise alarm: Light brightens from red to orange to white over a duration you choose in the app, then the alarm sound plays. Hatch doesn't publish the range of durations. Light: Brightness is set in the app. Hatch publishes no lux figure or color temperature. A bedside light button defaults to bright white at 50%. Controls on the device: Big Button (tap to snooze for 9 minutes, hold to stop, turn to change volume). Other controls are pause, a swap between up to three routines, a light button, an alarm slider and a button to pair with your phone Sounds and content: Sleep sounds, light options and the sunrise alarm come pre-loaded. Hatch+ adds more audio. It isn't a Bluetooth speaker. App and Wi-Fi: Free Hatch Sleep app for setup and changes. Hatch says Restore 3 requires Wi-Fi, 2.4 GHz only. After registration it can run phone-free. Power: Plug-in with the included cord. Hatch says to keep it plugged in. No battery is listed. Power draw isn't published.

Exact variant	US model HF3520/60 with colored sunrise, five natural sounds and FM radio	Putty, Greige or Cocoa, all $169.99 on Hatch's US store
Dimensions	Philips's manual gives the main unit as about 20 x 20 x 15 cm (7.9 x 7.9 x 5.9 in) and 0.76 kg (26.8 oz). The product page lists 19.2 cm high, 19.9 cm across and 14.6 cm deep, and 730 grams. The two sets of figures differ slightly. The page gives a 150 cm cord, and the manual gives the power adapter a 183 cm (6 ft) cord. Philips says to place the lamp 16 to 20 inches (40 to 50 cm) from your head.	Hatch's product page gives 7.24 inches long, 2.43 wide and 5.31 high, and a weight of 1.27 lb. Its help center specification page gives 7.5 x 2.75 x 5.75 inches and 19 ounces. The two sets of figures differ, and Hatch doesn't say which is current. Color is the only choice.
Installation	Nothing to install. Plug in the adapter, then use the menu buttons on the lamp to set the clock and a wake-up profile. A profile covers the wake-up time, light level, sound and volume. You can store two profiles. Philips says it is for indoor use only and not for a bathroom or near a shower. The lamp has no app, so there is nothing to set up.	Plug in the power cord and keep it plugged in, as Hatch's setup guide says. Then download the free Hatch Sleep app and follow its steps to connect the clock to Wi-Fi and register it. After that you can run routines and alarms from the buttons on the device. The box holds the clock, a power cord and a quick-start guide.
Materials	Philips doesn't state the housing material on the pages checked. The page lists a Lumiled Luxeon Rebel lamp and calls the light UV-free. The manual calls it a durable LED lamp that should last a long time, and it gives no lifespan. The base has anti-slip rubber feet. The manual says the power adapter is the only user-serviceable part.	Hatch's help center lists ABS plastic and LED lights with fabric. It doesn't name the fabric or list any certification.
Warranty	Two years from the date of purchase, per the manual and product page. Philips agrees to repair or replace a defective unit without charge. It doesn't cover accident, misuse, abuse or lack of reasonable care. It also doesn't cover damage in shipping. To start a claim you go to Philips's support site, and the manual suggests returning shipments by insured mail.	One year from registration, for the original purchaser. Hatch covers defects in materials and workmanship when the device is used as its manual describes, and the year starts when you register it in the app. Products from unauthorized resellers aren't covered. Hatch may limit how many replacements one person gets, and a replacement may be refurbished. Replacement units carry no warranty of their own. In the US you contact Hatch support within the year, and Hatch supplies a return label.
Returns	A 90-day money-back guarantee, with return shipping at your cost. Philips's user manual (copyright 2022) says to ship the unit prepaid by insured mail. You include the original sales receipt and a return authorization form, which you get by calling Philips support. It must be postmarked within 90 days of purchase. Philips says a refund check arrives 6 to 8 weeks after it receives the unit, and it may limit refunds to the suggested retail price. The product page names a 90 Day No Hassle Money Back Guarantee but doesn't print these terms.	30 days from the ship date, with free return shipping. Hatch calls this a 30-night bedside trial. The device must be bought directly from Hatch, and you start the return in Hatch's returns portal to get a prepaid label. There are no restocking fees, and the refund goes back to your original payment method after Hatch processes the device. Exchanges are only for another color of the Restore 3. A free Hatch+ trial has to be canceled through the app store, or it renews. A unit bought from a third-party reseller goes back under that store's policy.
Unresolved questions	Which studies Philips means by clinically proven The housing material Whether the light and alarm run at all during a power cut Typical daily power use, and which of the 12 W or 16.5 W figures applies Whether the 90-day guarantee terms in the 2022 manual still apply to a purchase from Philips's US store The shipping cost on Philips's US store Which size and weight figures are current, the manual's or the product page's	The sunrise durations you can choose and the light's maximum brightness in lux The color temperature of the white light Whether alarms keep running if the Wi-Fi connection drops, since Hatch says only that Wi-Fi is required Whether it has any backup battery, since the specifications list none and the setup guide says to keep it plugged in Power draw and typical use Which size and weight figures are current
