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.
One of the coolest features about this particular light alarm clock is that it doubles as a bedside lamp.
The way the Philips Wake-Up Light works is simple and easy. You set up your preferred wake up time for your personalized sunrise.
Before you go to sleep you can set the light, which also works as a bedside reading lamp, to dim slowly. The LEDs inside are not replaceable but are designed to last for many years.

What reviewers didn't like

Buttons are poorly positioned, pricey
Although it’s a beautiful alarm clock, it lacks multimedia/aux/USB support (although it has an FM Radio) and is not recommended for deep-sleepers or college students.
The solid, orb-like shape of the HF3520 made it difficult to lift away from the nightstand when I was dusting. Although the rear extension makes it more stable, that also means you can’t align the clock against a wall.
A bit pricey
LEDs are not replaceable. Control buttons can be fiddly
It’s a bit expensive, Round shape is fairly easy to knock over in morning confusion
