This 4-pack of Philips Hue white A19 dimmable LED smart bulbs has dropped to $39.99 on Amazon. That's $10 off its regular price. While this only matches a low we've seen a few times before, the pack has only dropped to this price once since last year's Black Friday shopping season.

Add these four bulbs to your smart home. If you're already a part of the Philips Hue ecosystem, then having four extra bulbs should be an easy addition to your home. If you aren't, you will need the Philips Hue hub to connect these bulbs to each other and your voice assistant system of choice. You can get the hub on its own (refurbished) or as part of one of many Philips Hue starter kits. The hub can control dozens of Philips Hue devices at once, so you can always expand later if you want.

Once connected through the hub, you can also connect the hub to your Amazon Alexa, Apple HomeKit, or Google Assistant smart home. Then you can turn these bulbs on and off with your voice, set them into groups, and more. Use the Philips Hue app on iOS or Android to turn the lights on and off, dim them to the desired level, set schedules, and more. These are standard white A19 light bulbs that are 60W equivalents.
