The Smart & Green Vessel 2 Bluetooth LED Indoor/Outdoor Lamp is a smooth, rounded version of the original Vessel. Apart from the updated design, this Vessel features the same tough, light-diffusing polyethylene body and convenient, retractable wood handle for easy carrying. A great piece to take wherever you need extra color and character. 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.
