The Philips Hue 3-bulb starter kit is on sale for $129.99 at Best Buy. It's $40 off Best Buy's usual price and about $30 off what it goes for at other retailers like Walmart (when it's in stock at all).

This is one of Best Buy's 4th of July deals. The larger sale continues all weekend and has dozens of ways to save on all kinds of tech. Check out our roundup of the full sale and look for big deals like $1,000 off TCL's latest and greatest 65-inch 4K Roku TV.

This kit includes three bulbs, a Philips Hue Hub, and a smart dimmer switch, which are all the things you'll need to start using smart lights. The hub is essential to the Philips Hue ecosystem. You'll need to connect all your bulbs to the hub to control them, and then you can easily connect the hub to your already existing smart home for some added control. The Hub itself is normally a $60 investment if you don't already have it anyway, and the dimmer switch regularly sells for $20 or more. So you're basically getting the three smart bulbs for $50 with this deal, which isn't bad at all.

To make these bulbs work, simply replace existing lights with the included A19 bulbs. The A19 fits in regular lamps and is probably the one you need the most. You'll have access to over 16 million color options, plus multiple different white lighting schemes. Thanks to the 3rd-generation technology, you'll find far more rich colors than previous versions of this kit.

Control the lights with your smartphone and a free app, or your voice and Amazon Alexa or another voice assistant. Each bulb lasts for over 25,000 hours, meaning that you'll save money compared to the costs of replacement bulbs before even factoring in the energy-saving LEDs that should lower your monthly power bill.
