![]() ![]() The maximum intensity of two of the devices we tested fell around the 300 range (measured from a distance that roughly approximates what’s between a sleeper’s eyes and the nightstand where the clock would presumably sit). While we didn’t measure the light intensity in this round of testing, we found that a manufacturer’s advertised intensity can vary from clock to clock. Generally speaking, to effectively wake you up, a light should fill your room. The higher-end options tend to emit light resembling a natural dawn, incorporating more nuanced shades of yellow, orange, and red. Often called wake-up lights, these devices gradually brighten over the course of a designated window of time (typically 10 minutes to up two hours), before reaching its highest level of brightness at your desired wake-up time. With this in mind, a growing number of brands are selling sunrise alarm clocks, and we set up a test to take a closer look. Depending on the time of year, relying on the sun might mean you’ll wake up earlier or later than you want to.

These clocks wake you up with a faux sunrise, and many give you the option of replacing the jarring sounds of a typical alarm clock with pleasant wake-up tones, such as chirping birds or wind bells, or even glorious silence. Whether you struggle to get a good night’s sleep or are simply not a morning person, a sunrise alarm clock may be your new best friend. ![]() CR engineer Dana Keester evaluates the user-friendliness of a selection of popular sunrise alarm clocks. ![]()
