Sunrise alarms ranked by max lux at pillow distance and sunrise duration. Those are the two metrics that actually map to a wake-time phase shift.
Philips SmartSleep HF3520 (Wake-Up Light)
Highest measured lux at pillow distance (~300 lux at 20 inches) in our set and the longest programmable sunrise gradient (20-40 min). It is the clinical research reference device: Gabel et al. 2013 (Chronobiol Int) used the Philips platform for dawn-simulation trials.

Philips SmartSleep HF3520
~300 lux max at pillow distance per manufacturer spec, 20-40 min sunrise gradient, sunset wind-down mode, FM radio. The Philips platform is what most peer-reviewed dawn-simulation trials have used.
Check price · Amazon - 02 ·Best UX
Hatch Restore 2
Lower peak lux (~200 lux at pillow) but the best app-driven routine in the category. Sleep sounds, meditation library, custom sunrise/sunset. Subscription tier for extended content. For UX-first buyers who want a bedside ecosystem.

Philips HF3510
Older Philips model, lower peak lux than HF3520 but ~half the price. 30-min sunrise, FM radio, no app. The right pick if you just want the Philips sunrise curve without smart features.

Lumie Bodyclock Shine 300
Lumie is the incumbent in UK/EU clinical settings. Shine 300 offers 20-90 min sunrise (unusually long), FM radio, white noise. Peak lux in the Philips ballpark. Harder to source outside UK/EU.

Lumie Bodyclock Glow 150
Mid-tier Lumie. 20-60 min sunrise, FM radio, audio options. Solid middle option between Spark and Shine.

Casper Glow
Pick-up-and-carry lamp with a dimming curve, not a full alarm clock. No audio, no radio. Lux is modest. Works as a bedside dimmer, not a therapeutic wake-up light.

Hatch Restore (original)
Predecessor to Restore 2. Fewer features, still the Hatch app and sunrise curve. Consider only if found at significant discount over Restore 2.

JALL Wake Up Light
Amazon-category budget sunrise alarm. 30-min sunrise, FM radio, USB charging. Peak lux well below Philips/Lumie. Works as an entry-level introduction to the category.

HeimVision Sunrise Alarm
Similar bracket to JALL. Programmable sunrise, audio alarms, nature sounds. Budget pick; do not expect clinical-grade lux.

Questions logged on this protocol
Does a sunrise alarm actually shift phase?
Modestly. Peak lux at pillow distance on the best models is ~300 lux, well below the 1,000-10,000 lux range where you see robust phase-shifting. Gabel et al. 2013 (Chronobiol Int) and Terman et al. 1989 showed dawn simulation improves wake-time alertness and cortisol awakening response. Pair a sunrise alarm with a 10,000 lux light therapy lamp during the first 30 minutes after wake for the full dose.
What should I actually look for?
Three specs in order: (1) max lux at your actual pillow distance, which is rarely published, so check for third-party measurements; (2) sunrise duration options, where 20-40 minutes matches the cortisol awakening response rise; (3) a true red-dominant sunset mode (warm, <2000K) for evening wind-down. Speakers, apps, and radios are nice-to-haves; the light metrics are the primary purchase criterion.
Hatch vs Philips, which should I buy?
Philips if peak lux and sunrise duration are the priority. Hatch if the app ecosystem, sleep sounds, and bedtime routine matter more and you are willing to trade some peak lux for UX. They are targeting different buyers. Hatch is closer to a lifestyle device with a sunrise feature; Philips is closer to a circadian device with some lifestyle features.
Will it wake me up without the audio alarm?
For many people, yes: dawn simulation alone produces a gentler wake in the last minutes of the gradient as light crosses threshold for EEG arousal. Budget units and heavy sleepers usually need the audio backup. Enable audio as insurance, set to a natural sound at low volume, not a buzzer.
Can I use it for shift work?
Yes, with timing inverted to match your schedule. For a night-shift worker sleeping 10:00-16:00, set the sunrise to begin at 15:30 and peak at 16:00. The circadian signal is the light gradient at wake time, not the clock time. Combine with blackout curtains for the sleep window and blue-blockers on the morning commute home.
Do I need one if I have east-facing windows?
Probably not in summer. Natural dawn delivers 1,000+ lux by civil twilight, much more than any alarm clock. In winter, or for sleepers whose habitual wake precedes sunrise by 30+ minutes, a sunrise alarm bridges the gap. The question is whether your wake time and your local sunrise align; if they do, windows win.

The Best Time to Exercise for Sleep: Why Evening Workouts Are Mostly Fine
Regular exercise is one of the most reliable ways to sleep better, and the old warning to avoid evening workouts has largely not held up. What the research says about how exercise improves sleep, whether the time of day matters, and the one narrow exception, vigorous exercise finished right before bed, that can genuinely delay sleep onset.
How Long Does Melatonin Last? Onset, Duration, and Why Timing Beats Dose
Melatonin does not work like a sleeping pill, and its short pharmacokinetics explain why. What the research says about how fast it kicks in, how long it stays in your system, why a big dose does not last longer in a useful way, and why when you take it matters far more than how much.
The Best Sleeping Position: What the Evidence Says and Why It Depends on You
There is no single best position for everyone, but the evidence does favor some positions for specific problems. What the research says about side, back, and stomach sleeping for snoring and apnea, reflux, back and neck pain, and pregnancy, and why comfort and the position you actually stay in matter more than chasing an ideal you cannot hold.
