Night-lights are as much for adults as they are for children. Whether you have to wake up in the middle of the night for a sleepy newborn, have a child who’s afraid of the dark, or need a low-wattage light to illuminate a hallway at night, night-lights have myriad uses. These lights cast a soft glow that is easy on the eyes and, for some people, aids sleep.

If you’re in the market for a night-light, the good news is that you have many to choose from. You should consider the type you’ll need — some night-lights project light, some are portable, and some require a socket to plug in. Also consider the bulb, including the type, wattage, and color.

Regardless of your needs, we at BestReviews are here to help. Take a glance at our product guide below, so you can pick the best night-light for you. Check out our favorites, too. Before long, with the help of a gentle light, you’ll be able to sleep soundly.

These days, night-lights come in all kinds of variations. Some of them include the following:

Plug-in: This type is probably what comes to mind when you think of a night-light. The light is attached to a simple two- or three-pronged plug. Access to a working electrical outlet is necessary for plug-in night-lights to work. It’s not uncommon to find a plug-in with a built-in sensor that automatically switches the light on when it’s dark and off once the sun rises.

Soft: Soft night-lights are essentially plush toys with a dim built-in light. This type is made for cuddling and is an excellent option for children who are scared of the dark. You can also put a soft light in a crib to comfort a baby to sleep.

Projection: These night-lights shine an image, like the moon and stars, on a bedroom ceiling or wall. These are popular with youth and children. Some kids’ lights project animals or cartoon characters. Additionally, there are projection night-lights for babies that emit soft music. The main drawback with a projection light is that the distance from the light to the ceiling or wall must be just right or the projected image will be distorted.

Portable: These night-lights run on batteries or are charged via USB, so they can operate anywhere. Portable night-lights are a great option for travel. They’re also pretty handy for camping, kids’ forts, or any other play activities that would benefit from soft light.

Brightness: As far as night-lights go, brightness is a deal breaker or maker. A night-light that’s too bright might disrupt sleep, defeating the whole purpose of buying one in the first place. At the same time, a light that’s too dim may not be bright enough for you to see by in the middle of the night. To test if the night-light is too bright, try it in the dark. Turn your head in the light’s direction and close your eyes. If you can still sense the light’s glow with your eyes closed, it’s too bright.

Light color: Blue and white light can actually disrupt your sleep pattern. This is because your body naturally associates those colors with daytime. The best color choice for a night-light is warm, such as orange, red, or yellow. Some people believe that red light most closely imitates the light a baby perceives in the womb. For infants, it’s especially important to find a soft red light.

Lampshade: Some night-lights come with a lampshade, which can be a nice decorative touch. A lampshade can also dim a light that’s otherwise too bright.

Night-lights are quite affordable, costing anywhere from $4 to $40, with most in the $4 to $25 range.

Inexpensive: The vast majority of nightlights that cost under $10 are simple plug-ins. The cheapest are LED and manual and have one light setting. You’ll find more white lights at this price, although there are a few models that change color. If you care about décor, you can easily find night-lights that come in cute shapes like stars or clouds.

Mid-range: Night-lights that cost between $10 and $25 have more options for the color of the light. There are many motion-activated night-lights in this range. You can also find some impressive projection lights at this price point.

Expensive: There’s really no need to spend more than $25 on a night-light, but if you’re itching to splurge, you can find some cute soft night-lights. There are also a few night-lights with elaborate lampshades at this price.

• Look for a night-light that’s cool to the touch for a toddler’s room. If the light will go in a small child’s room, a night-light bulb that doesn’t get hot reduces the possibility of burned fingers. Otherwise, just remember to unplug the light in the morning.
• Never use night-lights outdoors. They pose a hazard if they get wet. If you want to use a portable night-light for camping, be sure to keep it away from liquids.
• Guard against fire. If you’re worried about flammability, opt for a cooler, low-wattage LED night-light.

At BestReviews, we’re confident in all the night-lights we recommend above. If you’re searching for more options, though, we also favor the Athena Futures Moon Lamp. Users love the appearance of this simple, beautiful light that’s shaped like the moon. It looks great in any room, no matter the décor, and it includes several light settings, including amber. The lamp can operate with a remote or by touch, and charges via USB port or plugs in. It arrives in a cute box, too. We also like the GE Vintage LED Night-Light. This plug-in light is best for a hallway or entryway, office, or bathroom. Buyers love the aesthetic and the automatic sensor that turns it on at dusk and off at dawn. The warm white light is bright enough for late-night bathroom trips.

Q. Is there a difference between a night-light for a child and one for an adult?
A. Differences between the two are mostly a matter of style. Night-lights marketed for adults are more sophisticated and simple in style. Children’s night-lights may have playful designs or come in the shape of a toy.

Q. Are night-lights bad for you?
A. Opinions on this are divided, but those who claim night-lights are harmful blame a specific type of light bulb. Blue and white light inhibit the production of melatonin, a hormone that helps regulate sleep. If this is a concern, try to find a night-light with a warm-hued bulb or one that comes with color options.

Q. Can I leave a night-light on all night?
A. As long as your night-light isn’t near a curtain, bedding, or anything else that’s flammable, night-lights are fine to leave on during the night. Once it’s daylight, remember to unplug the light from its socket or turn it off. And always follow the manufacturer’s instructions.
