The fifth-generation Echo Dot With Clock is almost identical in appearance to the fourth-generation model. It’s a slightly squat 3.9 x 3.5-inch sphere (HD), available in light blue or white. The sphere is divided diagonally, with the top and front half covered in a mesh fabric and the bottom and back half enclosed in matte plastic. At the top of the globe, four rubber buttons protrude from the fabric. Around the flat base runs a ring of light that glows blue when you interact with Alexa, focusing a particularly bright spot to indicate the direction from which it registered the command. Philips Hue smart has simplified lighting by adding a White Ambiance bulb with warm white to cool daylight to give you the right light for everyday tasks. Use Bluetooth for instant lighting control in a room, or connect to the Hue Bridge (sold separately) to unlock all the smart lighting features. Use the Hue Bluetooth app to control your Hue smart lights directly in a single room of your home. Control your lights hands-free and with your voice! With simple voice commands, you can control multiple lights in a room or just a single light. Easy 2-step installation. Connect to your Wi-Fi, screw in your Hue Smart Bluetooth lamp, and download the Hue Bluetooth app to connect directly to your new lamp. Make your day easier and more enjoyable with four preset light recipes designed specifically for your tasks: Energize, Concentrate, Read and Relax. The two cool light scenes, Energize and Concentrate, help you get going or focus in the morning, while the warmer light scenes, Read and Relax, support pleasant reading or calm a busy mind. With a Hue Bridge, you can control up to 50 smart lights in your home.
