#Wake up natural light alarm clock upgrade

Even at its peak, the light doesn’t quite fill the room-it’s only 130 lux, compared with our main pick’s 300 and the entry-level Philips’s 200. Rather than simulating dawn or dusk, its white light simply grows from dim to bright within a 30-minute window-no fancy color nuances, and with a less gradual change than on our other picks. We also like that you can set multiple alarms during the week and that the sunset component comes with the option of several “wind down” routines, complete with calming sounds and (if you like) visual prompts to guide you in deep breathing.

#Wake up natural light alarm clock upgrade

We think it’s the intuitive app that truly makes the upgrade worth it, allowing you to program your sunrise and sunset times and other features much more easily than navigating the buttons on the clock. It also has sensors that detect temperature and humidity, noise, and light levels (which post readings on its app), a built-in nightlight (just tap if you need it), and a USB port.

But it offers more alarm sounds and a wider range of brightness levels and programmable sunrise nuances. The Philips SmartSleep Connected Sleep and Wake-Up Light (essentially the Bluetooth-connected version of the SmartSleep HF 3650, previously called the Somneo HF3650, our former upgrade pick) has many of the same features as our main pick, including a natural, red-tinted sunrise and sunset light. It’s for anyone who is eager to use their clock as an accessory for an entire sleep ritual. This upgrade isn’t for someone who is simply looking for a sunrise alarm clock to go to bed and wake up to.
