Fantasia Fairy Light Strings have very tiny and brilliant dual color white & warm white LED's on extra small diameter wire that has been silver plated. The 36 LED's are about the size of a grain of rice and are spaced approximately 2” apart. The silver wire adds to the ambience and light reflection. These decorative light strings can be submerged in water from the silver wire on. A battery holder is included. As an option, these can be powered by our ADAP-LLAS1000 plug-in regulated adapter set on 4.5V (sold separately). Uses 3 x AA batteries (sold separately).
