Our take

The HF3520 is the long-time favourite that made wake-up lights popular: the coloured sunrise from red to yellow feels natural, there's FM radio and two wake sounds, and it's simpler and cheaper than the Somneo. It lacks the newest wind-down features, but as a straightforward, effective sunrise alarm it's a safe bet.
