These are cool LED light that is also a Bluetooth speaker. The thing that sets these apart from other speaker bulbs is that these bulbs communicate with each other. You connect via Bluetooth to the Mother Bulb and the Daughter Bulbs sync automatically. You can have as many Daughter Bulbs as you want on the connection, and they will all play what the Mother bulb is playing.
I have these all through my house. They are worth a look.
