The Philips SmartSleep Wake-Up Light HF3520 simulates a sunrise and a sunset, which helps people wake up naturally and fall asleep more easily. Wirecutter's Phillip Zminda praised the red-tinted light for how closely it mimics natural sunlight, and the sunset function for promoting better sleep. The menu system isn't intuitive and the buttons are small, which is a problem first thing in the morning. Light sleepers who want a gentle wake-up will like it; anyone who prefers simple controls won't.
- — Gradual red-tinted light mimics natural sunrise to reduce grogginess
- — Includes sunset simulation feature to help users fall asleep
- — Tiny buttons around rim are difficult to navigate when groggy
