As of July 31, you can get a four-pack of Kasa smart light bulbs for just $24.99. That’s $15 off the listing price and breaks down to about $6.25 per bulb. It's also the lowest price we've seen on these bulbs, according to CamelCamelCamel.

If you haven’t heard of smart bulbs, let us introduce you to the future of lighting. The Kasa smart light bulbs (4-pack) do so much more than turn on and off. They can cycle through 16 million colors, be set to a specific hue, and even turn on and off via voice commands (with a compatible device like an Amazon Echo or Google Home).

The best thing about these bulbs is that you don’t need a smart home hub to use them — all you need is a WiFi connection and the free Kasa app. Once you've installed the app and connected the bulbs, you’re ready to go.

With the app, you can set schedules for when the lights turn on and off, dim them, and group multiple bulbs together. Plus, they come with a two-year warranty if anything goes wrong.
