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 featuring SMD LED technology emit superior, vibrant, radiating light and last even longer than traditional LEDs while still maintaining the virtually unbreakable, fade resistant, energy efficient benefits you want. Black wire disappears at night against most neutral-toned backgrounds, making it a great choice for lights any time of year. Create a professional quality Christmas light display this year when you hang OptiCore lights along your roof, around your trees, or anywhere around your home.
