Halloween is a holiday that screams for LED light bulbs

Back in the day, glow sticks were the best Halloween accessory. You could toss them in your jack-o’-lantern to give it a sickly green tinge or use it as a somewhat weak flashlight while trick or treating. But technology has evolved way beyond the glow stick’s short-lived chemical reaction. These days, smart LED light bulbs and strips can cast an eerie glow on command. LED light makers know this, and they’re taking full advantage this Halloween. Sengled’s combo bulb and speaker, Pulse, can sync up with Pandora or Spotify to dim or darken in time to the playlist. Up to eight bulbs can plunge your house into blackness in response to cues from the music, like Pandora’s Spooky Symphony channel.
