Fairdeer 50-Pack Fairy Lights 7ft 20-LED Warm White — Battery-Operated, 3 Modes, Waterproof Wire

Fairdeer 7ft battery fairy lights are compact, flexible warm-white string lights—each 20-LED strand runs on preinstalled LR44 batteries and offers three lighting modes for craft, jar, and event decorations.

These mini twinkle lights come in a 50-pack of identical 7-foot silver-wire strands with small battery pods already installed, so you can start decorating right away. Lightweight and bendable, each strand combines low-voltage safety, IP65 water resistance (battery pack excluded), and an unobtrusive battery box, making them useful for indoor displays, party centerpieces, and DIY projects where delicate, accent illumination is needed.

How long will each strand stay lit on the included batteries?

Each light strand includes three preinstalled 180mAh LR44 cells (540mAh total), sized and positioned to extend runtime compared with single-cell designs. Actual run time depends on the selected mode: constant lighting will use more power than blinking presets. These preinstalled batteries remove the immediate need to source replacements for initial use.

• Three LR44 cells per strand already installed for immediate use
• Mode-dependent runtimes: steady uses most power, flashing uses less
• Compact battery box for discreet placement

What lighting effects and controls are available?

Each strand offers three modes—fast flashing, slow blinking, and steady light—which you toggle with a small side push switch on the battery box. The silver-plated copper wire and warm-white LEDs create a gentle firefly-like glow suitable for ambient accents or focal highlights. Switching modes is simple and doesn’t require removing the battery housing.

• Fast flashing, slow blinking, and constant light modes
• Mini push switch on the battery pod for easy control
• Warm white LEDs for soft, neutral accent lighting

How can I use these lights for crafts, events, or outdoor displays?

The 7-foot flexible silver wire bends easily around jars, bottles, wreaths, and floral arrangements and can be wrapped or shaped without kinking. Thanks to the thin profile and small battery case, the lights tuck into tight spaces like mason jar lids or between branches. IP65-rated wire lets you use the strand in humid or splash-prone settings as long as the battery pod remains dry.

• Wrap around mason jars, vases, centerpieces, wreaths, or branches
• Thin wire hides inside decor for a floating-light effect
• Use outdoors where wiring may get splashed—keep battery pod dry

Are these lights safe and durable for repeated use?

The strands feature low-voltage construction and insulated silver-plated copper wire that runs cool to the touch, reducing heat concerns during prolonged use. The LED elements are compact and mounted along a flexible conductor that resists fatigue from gentle bending. While the wire assembly is rated IP65, the battery compartment is not waterproof—store and operate accordingly.

• Low-voltage, cool-running LEDs for safe handling
• Durable silver-plated copper wire for flexible shaping
• IP65 on the wire; keep battery pod protected from water
