LED Light Curtain Extralink 3×3 m, 300 LEDs, cold white, 5V USB – decorative string lights

Extralink LED Light Curtain 3×3 m with 300 cold white LEDs is a decorative string-light panel designed for even, low-voltage illumination of walls, windows, trees and display areas. The 3×3 metre curtain layout delivers a grid of lights that creates uniform coverage for seasonal decoration, retail displays or event backdrops. Power is supplied via a 5V USB connection, allowing safe operation from USB adapters, power banks or compatible USB outlets.

Advantages

The curtain format with 300 LEDs provides dense, consistent lighting across a 3×3 m area while keeping power consumption low thanks to the 5V USB supply. Cold white LEDs produce a crisp, neutral-white light suitable for both festive and ambient applications. The USB power option simplifies installation and makes the curtain compatible with common USB sources without the need for specialised mains adapters. The construction is intended for indoor use or sheltered outdoor locations, offering flexibility for seasonal and event decorations.

How to use

Unpack the LED curtain and lay it out on a flat surface to identify top and bottom edges. Mount the top edge to a wall, window frame or supporting structure using suitable non-damaging fasteners or hooks, ensuring the curtain hangs freely to maintain the grid layout. Connect the USB cable to a compatible 5V USB power source such as a USB adapter, power bank or USB outlet. Verify the power source provides stable 5V output and observe any controller or mode settings if present. For sheltered outdoor use, position the curtain under cover to protect connectors and the cable from direct exposure to weather.

Usage recommendations

Use a reliable 5V USB power supply rated to handle the curtain’s current draw; avoid connecting to low-capacity power sources that may cause voltage drop or flicker. For longer life and consistent performance, secure mounting points to prevent strain on the cable and avoid continuous exposure to moisture. When used outdoors, ensure USB connection and any controller remain protected from rain and condensation.
