Sylvania smart light bulb talks to Siri without a hub

You don't need any extra hardware to change the mood in your room.

If you've set up smart light bulbs like Philips' Hue, you've probably had to link your bulbs to a central hub -- and if you didn't, you may be making-do with only basic control. Sylvania is trying to do better. It's introducing a Smart Multicolor A19 bulb that doesn't require the hassles of setting up a hub, but can still give you advanced control through Apple's HomeKit -- and by extension, Siri voice commands. You only have to sync the Bluetooth lighting through iOS' Home app to illuminate a room.

As you might guess, Bluetooth imposes some limitations. You'll need an Apple TV or iPad to serve as a hub if you want to control the bulb when you're not within range. Still, this is potentially a wiser choice than many smart lights if you live in an Apple ecosystem and feel that a hub would only get in the way. There's no mention of pricing as of yet, but you should see Sylvania's latest bulb reach Amazon by early 2017.
