Smacen 12-Pack UV Black Light Fairy Lights – 7ft Copper Wire, 20 LEDs for Parties

Turn ordinary spaces into glowing scenes

Smacen 12-pack UV Black Light Fairy Lights offer a localized, magical glow that’s perfect for adding depth to any event or display. Each string runs 7 feet along a slender silver-colored copper wire, housing 20 LEDs that emit a UV wavelength in the 395–405 nm range. In a dark room, fluorescent materials like body paint, posters, fabrics, and decor take on a vivid blue-violet shimmer, helping speakers, performers, and guests notice key details without washing the space in ambient purple light.

Crafted for flexibility and reliability, the copper wire is bendable, so you can shape arches, frames, or drape backdrops to suit your design. Every string ends with a white battery case that holds two CR2032 batteries, making setup quick and portable. The copper wire is IP65 waterproof, enabling indoor or sheltered outdoor use, while the battery box is not waterproof, so avoid submersion or heavy moisture exposure.
