Hidden inside every intelligent Pulse LED lamp is a high-quality JBL stereo speaker which receives the audio signal wirelessly by Bluetooth to play music radio programmes or audiobooks. Simply screw the lamp into an existing E27 light socket & download our free Pulse app onto your smartphone or tablet. You can start playing music immediately & set the brightness just as you like it. Up to eight of these lamps can be wirelessly combined to create a multi-roomed audio system. That has to sound like music to your ears!
