Yes, tabletop LED décor can be used outdoors, but it's important to ensure they are specifically designed for outdoor use. Outdoor LED décor is typically designed to be weather-resistant, capable of withstanding elements like rain, wind, and sunlight. They should be waterproof or at least water-resistant to prevent damage from moisture. It is also essential to ensure that the power source and cords are suitable for outdoor use to avoid any safety hazards. Always remember to check the product specifications before using any LED décor outdoors.
