Raise your hand if you've ever whipped out your phone to capture that rich orange of the sunset as it hit your wall just right. Sunset projector lamps deliver that photo-worthy glow at any time of day, so it's no wonder they've become super popular recently. Beyond pure aesthetics, some users also note that the sun-mimicking lights help them combat the winter blues.

Curious to try one for yourself? Here's where to find them, how to set them up, and how sleep and circadian researchers recommend using them for a sunnier disposition.

Sun projector lamps are typically small tabletop lights that have colorful LED bulbs inside. When you flip the switch, they cast a yellow-orange circle of light onto nearby surfaces. Their circular head is adjustable; you can face it at a wall, up onto a ceiling, or down at the floor.

Scroll through TikTok or Instagram and you'll get a sense of all the ways you can use these colorful lights—from setting a funky tone for photoshoots to replacing standard mood lighting. In addition to sunset tones, some lamps can also be programmed to display different color schemes.

Once you're ready to use your lamp, simply plug it into a power source and face it at the surface of your choice. Users note that its hues tend to show up best in dark rooms, so you'll want to turn off any other lights first. Moving the light closer to the wall will make its colorful circle smaller and more vibrant; moving it farther away makes it larger and more diffuse.

While there's no right or wrong time to use these lamps, many opt to turn them on for a quick mood boost on winter nights when they aren't able to go outside to watch a real sunset. Director of the Sleep and Health Research Program at the University of Arizona and Casper sleep adviser Michael Grandner, Ph.D., adds that turning them on at nightfall may also help prime your body for good sleep.

This is due to the way that light helps train our all-important circadian rhythms. To keep these internal clocks running smoothly, we should surround ourselves with bright light in the morning and darkness at night, as we would in nature.

If you're looking to use a sunset projector lamp to support your internal clock, you'll want to turn it on around when the sun outside is actually setting, to simulate the colors you'd see out in nature. "A gradual fading of light might also help as well, to simulate dusk," Grandner explains.

While Zeitzer notes that a sunset projector lamp alone probably won't have too big of an impact on your sleep body clock, if it reminds you to dim the rest of your lights and begin the wind-down process, it will be a health investment well spent.

Grandner adds that if your lamp comes with multiple color options, you can switch to its bright white-, blue-, or green-enriched hues in the morning, "since they send a 'daytime' signal to your brain. That signal, when received early in the day, can help wake you up, increase daytime energy, and even improve mood during the day."

While your local hardware store probably doesn't carry them, sunset projector lamps can be easily ordered online. Here are a few well-rated options to look into:

Sunset projector lamps are nifty little devices that can fill your home with a sun-kissed color at any time of day. Sleep experts note that they may be helpful for keeping your circadian rhythm in check, but don't expect them to have much effect on your sleep or energy levels. If it's a snooze product that you're in the market for, these science-backed options are probably better picks.
