The Accent Lights feature “cut glass” style acrylic mini bulbs which produce a unique enhanced glow. The decorative string lights are spaced 6” apart with 12 lights per string. You can connect up to 5 strings together. (Note that red cannot be combined with white because of a voltage difference). Battery life is 20+ hours for a single string and less as strings are connected together. Ideal for table arrangements, party decor and holiday decorations.
