A sunrise alarm that brightens over 30 minutes so you wake gradually instead of to a harsh buzzer. Especially welcome on dark winter mornings.

Quick verdict

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.

What earns it the pick

  • A matching sunset fade to wind down at night

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
Why it matters

It eases you out of sleep with gradual light instead of a jarring buzzer, which is easier on dark mornings.
