You can easily switch to your preferred light mode and brightness as desired. Once the LED copper lights are activated, press the timer button on the remote control, which will automatically turn them off after a set period (6 hours on/18 hours off). | Plug-in Fairy String Lights: Supplied with a certified 120V wide voltage power adapter, simply plug it into your outlet and enjoy, with 12V OUTDOOR LOW VOLTAGE WIRE (lower than the safe human threshold of 36V), making it safe for children and pets to touch. These lights can serve as outdoor illumination for your garden, patio, tent, and more. | Versatile Use for Indoor and Outdoor Decoration: Ideal for embellishing bedrooms, windows, flower pots, porches, proms, tents, wedding receptions, and Christmas trees, creating a romantic ambiance. Can also be utilized as outdoor lighting for gardens, patios, backyards, lawns, balconies, porches, entryways, etc. | Energy Efficient: LED fairy lights utilize LEDs (light-emitting diodes) as their light source, consuming significantly less energy compared to traditional incandescent bulbs or fluorescent lights. LED fairy lights can deliver the same or even greater brightness at a lower wattage, which reduces energy consumption considerably. This not only helps lower electricity bills but also mitigates carbon emissions. Please reach out to us if you encounter any issues with the lights.
