FAQ:

Q: How does the Philips wake-up light alarm clock work?

A: The Philips Wake-Up Light Alarm Clock uses simulated sunlight to gradually rouse you from sleep. Thirty minutes before your desired wake-up time, the clock begins to glow, giving you the effect of waking during sunrise. You can also use this alarm clock as a reading lamp at night.

Q: What is the best sunrise alarm clock?

A: Philips SmartSleep Wake-Up Light HF3520 The best sunrise alarm clock This alarm has the most soothing simulated sunrise and sunset, which may help you feel less groggy. It has a good range of alarm sounds, a second alarm, power backup, and a sleek design.

Q: Do Philips alarm clocks stop when you hit the snooze?

A: Unlike with the Philips clocks, both the light and the sound stop (instead of just the sound) when you hit snooze; at least one online reviewer disliked this, though my husband actually preferred it. I woke soon after the alarm, but presumably deeper sleepers have noted that the sound alarm shuts off too soon.

Q: Which Philips alarms have red-light sensors?

A: The HF3520 and Philips’s two premium models, the SmartSleep HF3650 and HF3670 (our upgrade pick), are the only Philips alarms that offer a red-light component in their simulation, and science suggests that this approach may be more than a gimmick.
