9 Fairy String Lights Under $20 for a Dreamy Bedroom

There's something about fairy lights in a bedroom that no other decor element quite replicates. They add warmth, softness, and that magical quality that makes a room feel like a retreat rather than just a place to sleep. The best part? You genuinely don't need to spend much — the most popular options on Amazon clock in well under $20 and they look just as good as anything you'd find in a boutique home store.

Whether you want to drape them over your headboard, tuck them behind sheer curtains, canopy them above your bed, or frame a gallery wall, there's a specific type of light for each effect. Here are nine worth bookmarking, organized by what you're going for.

What's the Difference Between Fairy Lights and String Lights?

"Fairy lights" typically refers to lights on a thin copper or silver wire, which makes them flexible and virtually invisible when draped. Regular string lights use a thicker wire or plastic cord, which is more visible and structured. For bedroom use, copper wire fairy lights are almost always the better choice — they disappear into whatever you're decorating and the individual LED bulbs look like tiny floating stars.

USB-powered is the way to go for bedrooms since you can plug them into a phone charger or laptop port without needing an outlet in just the right spot. Battery-operated works too but you'll be changing batteries every few weeks with regular use.

The 66-Foot Option for a Full Canopy Look

If you want to wrap your entire headboard wall, drape a full canopy above your bed, or do a sweeping arc across the ceiling — 33 feet won't be enough. The 66-ft 200 LED version of most copper wire fairy lights doubles the coverage without doubling the price. Usually under $12, it's the pick for larger rooms or more dramatic installations.

The extra length also means you can double-layer sections for a denser, more luxurious look — bunching the lights slightly instead of stretching them out evenly makes a big visual difference.

Color-Changing Lights for a Mood-Setting Vibe

Not everyone wants warm white — if you want to be able to shift the energy of your room depending on your mood, color-changing fairy lights are a genuinely fun addition. The Minetom 16-color version lets you switch between warm white, cool white, red, blue, green, purple, and blended modes from a remote. Great for reading (warm white), winding down (soft purple or amber), or just having fun with the space.

These are also a hit for teen bedrooms, dorm rooms, and any space where customization matters more than a neutral aesthetic.

Globe String Lights for a Warmer, More Structured Look

If the ultra-thin copper wire look feels too delicate for what you're going for, globe string lights give you a warmer, more substantial presence. The individual globe bulbs create defined pools of light rather than an all-over shimmer, which reads as more intentional and grown-up. Drape these across a bare wall, above a window, or along a bookshelf.

The G40 globe bulb size (about 1.5 inches in diameter) is the most popular for bedrooms — small enough to feel decorative, large enough to put out real ambient light.

A Curtain Panel of Lights for Maximum Drama

A fairy light curtain — a grid of lights on hanging strands — creates one of the most stunning bedroom backdrops you can make without any tools. Hang it behind your bed as a glowing headboard alternative, drape it from a curtain rod over a window, or create a photo-worthy backdrop. Most curtain panels are 3 feet wide by 9 feet tall and pack in 300+ LEDs.

This is one of the single highest-impact bedroom decor items under $20. The "waterfall of lights" effect is something guests will always comment on.

A Star Projector for Ceiling Drama

If you want fairy lights to go above and beyond (literally), a star projector turns your entire ceiling into a soft, moving galaxy of light. These aren't fairy lights in the traditional sense, but they create the same dreamy, cozy atmosphere and pair beautifully with string lights. Most run off USB, have auto-shutoff timers, and project rotating or still star patterns in multiple colors.

This is especially great for kids' rooms, but plenty of adults swear by them as a wind-down ritual — lying in bed watching slowly rotating stars is deeply relaxing.

Rechargeable Battery Fairy Lights for Zero-Wire Setups

One of the most common annoyances with fairy lights is the wire running to an outlet — it breaks the magical illusion. Rechargeable battery fairy lights solve this completely. They run on a built-in USB-rechargeable battery (typically 2-4 weeks per charge), so you can drape them anywhere with zero visible cords.

Perfect for wreaths, terrariums, fabric canopies, or any spot where running a cord just isn't practical. The rechargeable versions are slightly dimmer than plug-in, but for ambient accent lighting in a bedroom, the difference is barely noticeable.

Clip String Lights for Your Photo Wall

If you have a gallery wall of photos, postcards, or art prints, clip string lights let you display them AND add that warm fairy light glow at the same time. The clips are evenly spaced along the wire (typically 20-30 clips for a 10-16 ft run) so you can swap out photos whenever you want without any frames or tape.

This is one of the most versatile bedroom decor setups — it's a photo display, mood lighting, and personal expression all in one. Popular with college students but honestly just as great for any bedroom.

The Simplest Option: A 10-Pack of Short Strands for Jars and Vases

For decorating small objects — mason jars, wine bottles, vases, terrariums, or lanterns — a pack of short battery fairy light strands is the most versatile buy on this list. Get a 10-pack of 6.5-ft mini copper wire lights and you can tuck them into any vessel, layer them in a glass bowl, or stuff them into decorative lanterns for an instant glow.

These are almost always under $15 for a 10-pack, which makes them one of the best value decorative buys in the bedroom category.

Quick Tips for Bedroom Fairy Lights

• Use removable hooks (Command strips) to hang copper wire lights along a wall without putting holes in your drywall
• For a canopy effect, attach four hooks to the ceiling above your bed and let the lights drape down and outward
• Warm white (2700-3000K) is best for bedrooms — cool white or daylight looks harsh at night
• Keep lights on a timer (most remotes have one) so they turn off automatically after 2-4 hours — you won't have to think about it
• Layer two or three different types for the richest look: a copper wire base layer, a curtain panel behind the bed, and globe lights along a shelf

Fairy lights are genuinely one of the most transformative and affordable bedroom upgrades there is. Found something you love? Pin this for later so you can come back when you're ready to create your dreamy setup!
