Plus, these bulbs come with a lot of super cool features! You can set specific times for the bulbs to turn on and off, use their "sunrise" and "sunset" modes to ease you in and out of the day, sync with your music so the lights change based on the rhythms and dynamics of your favorite songs, AND you can use your camera and photos to select the specific color you want your bulb to match.
Promising review: "I love this lightbulb! The app you download for it is very user friendly, and I adapted to it very quickly. You can adjust brightness and the color all from your phone. One of my favorite features is 'scene.' It has a variety of options like 'romantic,' 'reading,' and the coolest in my opinion: 'sunrise/sunset.' Over the span of 15 minutes, it mimics the colors of a sunrise/sunset. It goes from red, to orange, to purple, etc. It’s a very cool lightbulb and I recommend it to all of my friends." —Kristina Adamik
