Philips SmartSleep HF3519 review: 300 lux, two alarms and FM radio, and the dawn without the red
Philips' mid-range wake-up light: a sunrise of 20 to 40 minutes rising from yellow to white, up to 300 lux in 20 steps, five wake-up sounds, FM radio, two alarms and a sunset to fall asleep to, in a 20 cm lamp. This review is about what a stated brightness tells you, why two alarms suit a couple, what the missing red phase means, and how much bedside the lamp needs.
