Product Details
Why is the wire green instead of traditional copper color?
The green coating is designed to blend in with Christmas tree foliage, wreath greenery, and garlands. This makes the wire nearly invisible among the branches while the LEDs stand out beautifully.
What length of USB LED string lights do I need for my Christmas tree?
For a small tabletop tree, 5m (50 LEDs) is sufficient. For a standard 6-foot tree, 10m–20m works well. For large 7–9 foot trees or outdoor displays, the 30m (300 LED) option provides generous coverage.
Are these USB fairy lights safe to leave on overnight?
LEDs produce minimal heat and are generally safe, but we recommend using a USB timer adapter to turn them off automatically and following standard holiday lighting safety practices.
Can I use these string lights outdoors?
While the green copper wire is flexible and durable, check the product's IP rating for outdoor suitability. For outdoor use, ensure the USB connection point is kept dry and protected.
What lighting modes does the remote control offer?
The remote allows you to switch between modes such as steady glow, twinkle, slow fade, and flash effects, plus adjust brightness levels for the perfect holiday ambiance.
Can I connect multiple sets of these USB string lights together?
Each set operates independently from its own USB power source. They are not designed to be daisy-chained together. Use multiple USB ports or a multi-port adapter for multiple sets.
