Ranked #4 in Best Sunrise Alarm Clocks

Lumie Bodyclock Glow 150

4.0

1 source$139as of Oct 20

The Lumie Bodyclock Glow 150 is easy to operate and gives you more sunrise options than the Rise 100, anywhere from 20 to 45 minutes. Reviewers found it simple and liked the nature sounds, but noted you have to re-enable the alarm every day and brightness adjusts only in five coarse steps. It avoids the flicker problems that affect the Shine 300, and it skips the Bluetooth streaming the Luxe 700FM offers. It suits people who want straightforward operation rather than advanced features.

Strengths

— Simple to use with intuitive navigation
— Offers more sunrise customization (20-45 minutes) compared to fixed 30-minute rise time
— Includes nature sounds alarm option

Watch-outs

— Requires manual re-enabling of alarm daily
— Does not support Bluetooth streaming

Philips SmartSleep Wake-Up Light HF3520

4.1

1 source$106.99as of Oct 20

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.

Strengths

— Gradual red-tinted light mimics natural sunrise to reduce grogginess
— Includes sunset simulation feature to help users fall asleep
