‘Wake-up lights’ are alarm clocks that use light, rather than noises, to awaken sleepers. Because the circadian rhythm controlling our sleep cycles corresponds to natural light and darkness, the light method is fairly effective for most; the method is particularly popular with sleepers who find waking up to an alarm unpleasant. Most wake-up lights mimic natural sunrise by gradually becoming brighter until the preset wake-up time. The lights are usually yellow and/or white, but some models offer a wider light color selection.
Like standard alarm clocks, wake-up lights also come with adjustable volume, snooze functions, and multiple preset options. Some offer AM/FM radio as well. In most cases, the light timer is also adjustable; this enables owners to program the light for up to half an hour or longer before waking. Many wake-up lights are backed by both sleep trials and warranties. The average model costs about $40 to $50, but products range anywhere from less than $20 to more than $150.

Not everyone wants to begin the day with a noisy alarm clock ringing in their ears. There are all sorts of alternatives emerging on the market, and one popular option is a “wake-up light.” A wake-up light is a type of alarm clock that uses light rather than sound to stimulate sleepers to wake.
These light-based alarm systems work with our body’s natural wake-sleep or circadian rhythm, making it easier to drift off to sleep and then wake with ease in the morning. Please read on to learn more about Tuck’s top picks for wake-up lights, how wake-up lights work, and important considerations for buying them.
Today, more and more sleepers are moving away from traditional alarm clocks. For many years the market supported loud, jarring sounds as the only way to wake you up on time. However, these loud noises can feel more disruptive to one’s natural sleep cycle than helpful. There are a few sound reasons to consider a wake-up light as an alternative to traditional alarm clocks.
Light affects your circadian rhythm: There are multiple cues on which your body relies to signal its sleep and waking rhythms. One of them is light. At one time, early man only functioned when natural light was available, and then slept once the sun went down. Thanks to artificial light sources, modern humans can function well into the night, often at the expense of our circadian rhythms.
By using a wake-up light to drift off to sleep and wake in the morning, you’re doing the work of resetting your body to respond to light as a cue that it’s time to go to bed or time to wake up.
Wake-up lights aren’t disruptive or jarring: You want to start off your day feeling well-rested and prepared. A loud noise will make you feel startled and disoriented. But wake-up lights seamlessly ease you into a conscious state.
Some lights are multi-functional: In addition to functioning as an alarm, some wake-up lights can be used as reading lights, nightlights, or even as a substitute flashlight.
It’s a simple way to improve sleep hygiene: Developing proper sleep hygiene, or good habits and behaviors you use to prepare for bed, is fundamental for getting a good night’s sleep. By setting up and using a wake-up light every day, you also work in an important nighttime habit that will let you get the right amount of sleep each night.
Our bodies operate on an internal clock that controls the circadian rhythm. During dark periods, the brain releases more melatonin, a hormone that makes us feel tired. This is why most adults feel sleepy at night and more alert in the morning. Circadian rhythm also explains why people tend to feel more tired during the winter and fall, when daylight is less prominent.
Traditional alarm clocks may be effective for many sleepers, but the harsh, loud beeping associated with most models can make waking up more of a chore. Sleepers are more likely to hit their snooze button or sleep in if the alarm goes off but they still feel tired. By simulating natural light, wake-up light alarms help sleepers feel more alert when they awaken. Most clocks will produce light roughly 30 minutes before the audio alarm goes off.
Wake-up lights sold today may have up to 20 brightness different settings, though most have between three and 10. Light brightness is measured in ‘lux’ units. Most wake-up lights offer settings of at least 200 to 230 lux, which is comparable to a low-lit office. Some models provide up to 10,000 lux, which is comparable to outside light on a bright day.
Other features and functions of some wake-up light alarms include the following:
Here are a few variables to keep in mind when shopping for a new wake-up light and comparing different brands and models.
