Philips SmartSleep Wake-up Light HF3520/60 review
A feature-rich bedside light for sunrise waking, with radio and separate alarms.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
A bedside lamp and alarm clock in one, the Philips SmartSleep Wake-up Light HF3520/60 is aimed at people who want light to become part of waking up, rather than relying only on a buzzer. Its colored sunrise gradually brightens over an adjustable 20–40 minutes, and a sunset simulation dims the light for winding down. With two separately configurable alarms, it can suit a bedside routine that needs distinct alarm times. It is a physical, desktop-use product, not a connected sleep platform.
The waking options give this model more flexibility than a light-only alarm: choose among five built-in natural sounds or FM radio, and set light intensity across 20 brightness settings. The display automatically adjusts to room lighting, while a tap silences the alarm for a nine-minute snooze. These controls make it a practical fit for someone who wants to tailor both light and sound at the bedside. Those seeking projection features should look elsewhere; this model does not include projection rotation.
For backup, the manual specifies four to eight hours of time backup. That specification does not establish that the clock will sound an alarm during a power outage, so it should not be treated as outage-proof waking. The product is paid, and Philips offers a 90-day refund period. Documentation is the listed support channel. Choose the HF3520/60 if sunrise and sunset light, radio, and two alarms are central to your routine; consider another clock if projected time or confirmed alarm operation during an outage matters more.
