With a single Philips Hue smart bulb, you can switch up the feel and mood of a room at any time, going from cozy to vibrant colors with just a tap on your smartphone. Right now, one of the more versatile Philips Hue smart bulbs — the White and Color Ambiance A19 Dimmable LED Smart Bulb — drops to $39.99 at Amazon. This is a match of one of the best deals we've seen this year, outside of a brief additional coupon that brought it a few bucks lower.

You'll be able to begin controlling this smart bulb using your iOS or Android smartphone right out of the box, or even with your voice if you have a separate device featuring Amazon Alexa or Google Assistant, such as the Echo Dot or Google Home Mini, along with the Philips Hue Bridge, which you'll need to purchase separately.

Using your phone and the Hue app, you'll have the ability to choose from over 16 million colors to light your bulb with, along with custom presets if you have more Philips Hue bulbs at home. This bulb is dimmable and can be scheduled to turn on or off at a specific time each day via the app, even while you're away from home.

Other Philips Hue products are on sale for Cyber Monday currently too, such as the four-pack of white dimmable bulbs for $40 and the White & Color Ambiance LightStrip+ for $60.
