The Smart & Green Flatball Bluetooth LED Indoor/Outdoor Lamp is soft, squat and splashy (in more ways than one). It is made out of durable and waterproof polyethylene, which means it can be used inside or outside, or even floating in the pool. It has a variety of light modes (color-changing, dimming, etc.) to create just the right ambiance. To change the color, dimming, scheduling and even have multiple products communicate with each other, simply download the Smart and Green app. Using Bluetooth mesh technology without a WiFi network, you can control various scene modes from your own smartphone.
