Amazon currently has the Philips Hue colored A19 60W Smart Bulb on sale for just $38.97. That's a great price for an individual bulb, considering these usually go for around $49, taking about $10 off of the regular price.
The Philips Hue White & Color Ambiance bulb is a standard A19 smart bulb from Philips, which will work in most light sockets in your home. It's a great smart bulb to pick up since you'll be able to use it in just about any lamp or light socket, and it is also capable of doing millions of different colors. So you can put this in the lamp by your bed and have it do all kinds of different colors. The Philips Hue bulbs are all controlled by its Android and iOS apps, but it also works with Amazon Alexa, Google Assistant and Apple's Siri assistants, so you can use your voice to control the lights. Now remember, this bulb is only worth picking up if you already have the Starter Kit from Philips Hue. The reason for that is because it needs to connect to the Philips Hue Bridge, which is included in the starter kit, but can also be picked up individually for $49.99. Otherwise, this is a great way to add to your Philips Hue collection and make your entire home smarter.
