With a good discount, this is another good Amazon Prime exclusive offer for a fourth-generation Amazon Echo smart speaker that includes a Sengled Bluetooth color smart bulb. With Alexa, Echo can play music, answer questions, control your smart home devices, and buy things on Amazon, all with your voice commands. The Echo is our choice for Alexa’s best smart speaker, and while this Sengled bulb isn’t one of our choices of smart LED bulbs, we’ve recommended some of its bulbs in the past and it is a solid complement.
