Naturally wake up with a colorful sunrise simulation: Like a real sunrise, the Philips Wake-up Light gradually wakes you up within 30 minutes, transitioning from soothing morning red to warm orange, and then to radiant yellow that floods your room with light. This gradual light progression promotes natural and soothing awakening. You can also choose from 20 brightness settings to customize your experience.

Natural sounds for gentle awakening: You have the choice of 6 different sounds for your wake-up, or even the option to wake up to the sound of your favorite radio show thanks to the built-in FM radio. The sound you choose accompanies the gradual increase in light for a gentle awakening.

Designed for your comfort: The Wake-up Light features soft light to guide you in the dark, display brightness that adjusts automatically based on ambient light, and a one-touch snooze function for a gentle wake-up after 9 minutes.

Proven effectiveness: This is the only wake-up lamp with clinically proven effectiveness. Philips, with over 100 years of lighting expertise, has conducted numerous independent clinical studies to prove that the Philips Wake-up Light not only helps you wake up more naturally but also improves your mood in the morning.

Naturally wake up and fall asleep: In addition to waking up gently, you can use the sunset simulation function to prepare your body for sleep by gradually reducing the brightness over a duration of your choice.

Customized to your preferences: You have the choice of 20 brightness settings to customize light intensity. The nightlight function is designed to gently illuminate the room without disturbing your sleep.

Easy to use: The Wake-up Light is easy to use with non-slip rubber feet, an alarm with a snooze function, automatic display brightness control, and the ability to set up to 2 alarms. Additionally, it features the tap-to-snooze function to activate the sound 9 minutes later.

In summary, the Philips SmartSleep HF3521/01 Wake-up Light offers you a natural and pleasant way to wake up by combining light and sound for a gentle awakening, supported by Philips' decades of lighting expertise.
