Brightech's Ambience Pro Solar Globe String Lights creates a beautiful backyard atmosphere where you can sit back, relax, and enjoy your evening. Featuring our standard high-efficiency shatterproof LED G40 plastic bulbs (with heat resistance up to 122 degrees Fahrenheit), the 12 bulbs are spaced 20-inches apart on a 27-foot rubberized flexible thin cord. Our string lights can also be combined together, with the capacity to connect up to up to 8 strands. With 6 feet from the solar panel to the first bulb and an additional 3 feet at the opposite end, our lights can offer the flexibility you need to fit the dimensions of your space. Our lights also feature a detachable solar panel with an on/off switch located on the back. The built-in photocell senses light, turning on your lights automatically at evening time so that you can enjoy your beautiful outdoor lights without any of the hassles. Our lights last 5-6 hours on a full charge. Thanks to Brightech's WeatherTite (TM) technology, these gorgeous lights are waterproof/weatherproof to a commercial grade. Include the perfect glow to your evening when entertaining your guests or add that romantic touch to your dinner date.
