Purple and green are one of the most popular Halloween light color combinations, and with good reason: nothing creates an eerie glow like these two colors together. And our commercial grade strings and energy efficient LED bulbs combine to create a high impact, professional quality display that will deliver season after season. Opticore bulbs emit superior, vibrant light while maintaining the unbreakable, energy efficient benefits you want. Plus, these string lights are end-to-end connectable, so you can connect different lengths together up to 1,000 feet (960 max watts). Black wire disappears at night against most neutral-toned backgrounds, making it a great choice for lights any time of year. Hang these lights along the roof, across a porch or fence, or wrap them around trees for your most exciting holiday light display ever!
