Philips makes some of the best smart light bulbs on the planet, but they can get pretty expensive. Just one of those fancy colored bulbs costs $50. If you don't care for the color-changing bulbs, the A19 Starter Kit is $40 off at Best Buy and Amazon.
This kit has four A19 LED light bulbs and the required Philips Hue hub. That's a pretty great deal when you consider that just two bulbs without a hub cost around $30. As mentioned above, these are the plain white LED bulbs, not the fancy colored ones. They can be dimmed or turned on/off through the Hue app, or through voice commands with Alexa/Google Assistant.
If you're more in the market for light strips, the Hue LightStrip Plus is $49.99 at Amazon and Best Buy, a $40 savings over the usual price. Sadly, that product doesn't come with a Hue hub, so you'll need to get one separately (if you don't already own one). You can buy the A19 Starter Kit from the source links below.
If you do want some colored Hue bulbs, you can get a 3-pack of the 3rd Generation Ambiance bulbs for $114 from Amazon. That's a $60 savings over the usual price, and it also comes with a hub.
