Amazon currently has a four pack of the Philips Hue white A19 bulbs available for just $39.97. That's good for $10 off of its regular price, and it also brings the price down to an all-time low.
Philips Hue bulbs are smart bulbs, so you can control these bulbs with your smartphone. These also work with Amazon Alexa and the Google Assistant. Allowing you to control them with your voice, as well as setting schedules and so much more. Keep in mind that these are the white bulbs, so there's no colors here. These will work great in most ceiling lights that you don't want to turn to turn blue or green at any point. That also explains why these are much cheaper than the regular Hue starter kit. This is a starter kit, so the Philips Hue Bridge is also included.
