This smart LED bulb can be controlled from an App on your Android or iOS phone or from voice commands using your Alexa or Google Assistant. From the comfort of your seat (or from anywhere across the internet) you can easily command the light to adjust for your mood, from a comforting warm white up to a cool white for reading, etc. You can also dim the brightness without the need for an external dimmer, and set up automatic schedules using the App. Family members can be provided access to control the same devices, and multiple lights can be controlled simultaneously.Available with Bayonet or Edison Fittings, sold individually or in three packs.SL2250: Bayonet (B22), EachSL2252: Bayonet (B22), 3 PackSL2254: Edison (E27), EachSL2256: Edison (E27), 3 PackNote: 2.4GHz Wi-Fi network required.
