Review – Nox Smart Sleep Light

Nox Smart Sleep Light

While I’ve written about plenty of light alarms because the concept intrigues me, I’ve not had the chance to use one yet. Someone reached out to me to try the Sleepace Nox Smart Sleep Light, and I was obviously keen to test it out. Of course, trying out a pre-order product that has to do with waking you up in the morning can be risky business for those on a schedule.

The Look

The Nox is shorter than a bedside table lamp, and doesn’t take up a lot of space width-wise. It has an opaque white casing at the top that the light is diffused through, and has light gray at the bottom. It’s very lightweight, which made me worry for a moment as devices are usually not so light unless they’re advertised that way. Once I plugged it in and started fiddling with it a bit however, my fears subsided. A bright white digital clock appeared at the bottom in the gray area, and I followed the instructions to get it working.

The only touch capacitive buttons you interact with are on each corner of the flat gray top, while a circular indent at the center is the the on/off button. Your preset options for controls are to brighten or dim the light, and raise or lower the volume of the preset music. The center button turns on and off the light and/or sound. Your only options for sound are preset, so there’s no connecting to your music library or streaming from an app through this device. In the back is a spot to plug in the cable for Nox which will need access to a wall outlet, and a USB port to charge your devices. Just above these ports are the many holes for the speaker. It’s a pretty simple design that shouldn’t clash with any existing decorum.

How It Works

If you don’t have their other device for monitoring your sleep, you can use your smartphone by laying it face down near your pillow. The sensors in your phone will give the corresponding Nox app data as to what sorts of movements your body is doing. That information is put into the app, along with info such as your sleep efficiency, body movement score, how quickly you fell asleep, what levels of sleep you were in, the temperature of the room, the humidity, noise levels, and light levels. The data is processed and displayed in an easy-to-read way, and has helped me care more about the quality of sleep I’m getting. The app is honestly my favorite part, and doesn’t necessarily require the Nox. However, lots of information such as the temperature, humidity, noise, and light levels won’t be included in the app reports without it, making it harder to discern what might be affecting your sleep. Since I always fall asleep within 3 minutes and stay asleep all night, those factors don’t influence my sleep too much. Those who do have trouble falling or staying asleep could benefit greatly from the information this device would provide though.

The first night I went through all the steps to connect my phone with the device. It was pretty easy to figure out, and gives you a lot of options to customize. You get to pick the hue of the sleep aid light from red to yellow (these are sunset colors, and help your brain wind down in the evening), the brightness of the light, whether it comes on or not at all to help you sleep, the preset music, and how loud the music is. It even has an intelligent off that will shut off the light and music when it can tell you’ve fallen asleep. There are also light options for mood lighting with bright white, a color, or a cycle of colors that you can brighten or dim as well.

Nox back


One of the drawbacks I was met with were some connection issues. There were two nights in a row I had to completely redo the pairing process (which doesn’t take long but we’re all lazy). The alarm just plain ole didn’t go off the second night, which I was running so late at that point that there’s a chance it could have been human error on my end as I may have either accidentally turned off the alarm, or didn’t wake up to the sound and light, but again, this was only once. I will say that I haven’t had connection issues since. My nit-picking in the audio department is that the speakers could have been a little better quality as they were a bit tinny sounding, and the music had a little blip at the end of some of the loops. The options for music to wake up to mostly came across as generic bouncy commercial jingles which annoyed me more than woke me up, and the few things that I could sleep to for their sleep aid sounds, like waves or rain, had the blip, which was more apparent since the tracks were so calm. It wasn’t enough to bother me as it was a pretty long loop, but it did surprise me enough once to startle me awake as I was drifting off. Notice that I only said once, but it’s something to keep in mind if you’re all about audio as you wouldn’t want to use that aspect if your standards are too high.


This device has so many functions that when it falls short in one area, something else makes up for it. It’s a $149.99 purchase, and compared with other light alarms around the same price, Nox far outplays their functionality. This is a multi-device in that it is a lamp, mood lighting, alarm, and a sleep, temperature, humidity, sound, and room light monitor. When all is said and done, it does stack up enough different variables to be worth the price. The free app is definitely worth downloading whether or not you get Nox as you only need your phone to use it and it can give you a lot of insight into your sleeping habits in an understandable way. However, Nox adds a lot to understanding your sleep patterns and the light really does help you wake up and will help spice up ambient lighting even if it’s not bedtime.
