Amazon has the Philips Hue White A19 60W Smart Bulb Starter Kit on sale today for just $55.79. That is actually a really great price for this starter kit, seeing as this particular one goes for $69 normally, and has never really dropped below $60. This is a four-pack of white smart bulbs that you can use to make your lights at home, a bit smarter.
These lights from Philips Hue are smart white bulbs, these are not the multi-colored bulbs, which is why you're getting four for just $55.79, as they are far cheaper to make than colored bulbs. These will still work with the Philips Hue app, and since this is the starter kit, you are also getting the Philips Hue Bridge, so that you are able to actually connect these to your Internet. Philips Hue also supports Amazon Alexa and Google Assistant, so you are able to control these lights with your voice, using your phone or a smart speaker in your home. Philips Hue is a pretty big ecosystem, so this is a great product to pick up, as you'll be able to add a slew of other products to your home, and still be able to control them all with your voice or with the app on your smartphone - the Philips Hue app is available on both iOS and Android.
