If you’ve been toying with the idea of building out the Philips Hue smart lightning setup in and around your home, today is definitely the day to do it. 4-packs of Philips Hue White A19 60W Equivalent Dimmable LED Smart Bulbs are down to just $39.99 if you’re willing to buy renewed — and there’s no reason not to since they’re guaranteed and warrantied. That’s just $10 a bulb, which matches an all-time low and is likely the lowest price you’ll ever find on these awesome LED smart bulbs.

Here’s more info from the product page:

  • Automate your lighting experience with Philips Hue and control your lights from home or away. Create light schedules from the Philips Hue App and never come home to a dark house.

  • Install the LED lights as you would install ordinary bulbs and pair them with the Hue Bridge, which allows you to control smart-bulb-equipped lamps and overhead lights via the Philips Hue App.
  • Easily expand your lighting system with accessories (sold separately), such as a Hue Dimmer Switch, Hue Tap, or Hue Motion Sensor. Pair it for automation with your existing Nest or SmartThings system.
