1 This is a really bizarre idea – a power-efficient lightbulb that, for some reason, also has a Bluetooth speaker built into it.

To be fair, the sound quality from the JBL speaker isn’t too bad at lower levels, so the Pulse might be a handy way of sending toddlers off to sleep at night – and you can use the iOS app to gradually lower both the music and the light until the little ‘uns drop off.

Unfortunately, the compact little speaker struggles at higher volumes, and can’t really handle anything more than low-level background music. Cliff Joseph

The Pulse might be handy for the kids’ bedroom, but it’s no replacement for a conventional Bluetooth speaker system.
