Frequently asked questions
Does a sunrise alarm actually work?
For most people, yes — light suppresses melatonin and advances your cortisol awakening response, so you surface from sleep gradually instead of being yanked out. The effect is strongest for people who wake before dawn or sleep in dark rooms.
HF3520 vs the cheaper JALL?
The Philips ramp is smoother (real dimming curve, not visible steps), the light warmer at low intensities, and the build noticeably better. The JALL wakes you fine at a third of the price — the Philips just does it more gently.
Can it replace light therapy for winter blues?
It's wake-up light, not a 10,000-lux therapy lamp. It helps with dark-morning grogginess; clinical seasonal affective treatment needs a dedicated bright-light box.
Is there an app or smart features?
No — and that's a feature. Alarm, light, radio, done. If you want routines, meditations, and phone control, look at the Loftie or Hatch instead.
