A sunrise alarm that brightens over 30 minutes so you wake gradually instead of to a harsh buzzer. Especially welcome on dark winter mornings.
A sunrise alarm that brightens over 30 minutes so you wake gradually instead of to a harsh buzzer, and it doubles as a bedside lamp. Best for someone who dreads dark winter mornings, though it's pricey for what is mechanically still an alarm clock.
Best for someone who wakes groggy on dark winter mornings and wants a gentler, gradual start
What earns it the pick
- A colored sunrise that brightens from dim red to warm white over 30 minutes
- A matching sunset fade to wind down at night
- Five natural wake sounds plus FM radio, with tap-to-snooze
- Doubles as a dimmable bedside reading lamp
The honest catch
What we’d want you to know before you buy.
- Expensive for an alarm clock
- Heavy sleepers may still need the backup sound, since the light alone may not fully rouse them
- This HF3520 model uses physical buttons with no app or smart-home connectivity and offers only a handful of wake sounds plus FM radio
It eases you out of sleep with gradual light instead of a jarring buzzer, which is easier on dark mornings.
