Since you'll mostly be controlling these lights from your phone or tablet, you want to make sure that it's easy to do. If you have multiple bulbs, for instance, you'll want a companion app that lets you easily arrange them in groups, and adjust the brightness and/or color of an entire group at one time. Do you have a smart display or smart speaker? Look for a bulb that works with Alexa or Google Assistant so you can control it with your voice.
Of course, any bulb plugged into a socket can always be turned on or off by just flipping the switch. We pay close attention to how each app works, and provide a detailed overview in each review.
Smart Bulb Features
Smart bulbs offer a degree of control and interactivity you just can't get with traditional bulbs, like scheduled timers and remote control options. They're also more convenient; it's easier to tap on a smartphone screen than to get up and trudge over to a wall switch.
Aside from keeping you out of the dark, most of the bulbs listed here can be scheduled or controlled remotely, which is great if you want to save on energy costs or often forget to turn off the lights before leaving the house. Some bulbs use geofencing, which means they work with the GPS in your smartphone to pinpoint your exact location, and can automatically turn the lights on or off when you get home or leave the house. Color-changing bulbs are great for mood lighting, and some can even sync up with certain movies and TV shows.
As touched on, some bulbs hook up with Amazon's Alexa, Apple's HomeKit, or Google Assistant, so you can control your home lighting with your voice. You can also integrate some of the bulbs on this list with security cameras, thermostats, and other smart home devices. If This Then That (IFTTT) compatibility lets you create recipes that automatically cause your lights to react to certain triggers, like phone notifications or changes in weather.
Right now we don't recommend bulbs that do double-duty as a speaker, as we haven't found any particularly good ones in testing.
Do Smart Bulbs Need a Hub?
There's one more important factor to keep in mind. Some smart bulbs need to connect to your smartphone through a home automation hub like the Philips Hue Bridge. Other bulbs cut out the middleman and connect to your phone or tablet directly via Wi-Fi, while some connect with Bluetooth, but in that case, you're limited to control only when you're within Bluetooth range, which means you can't change the lights when you're away from home. Adding a hub also means spending a bit more money and requires an additional step in the installation process.
With all that in mind, we've gathered the best smart bulbs we've tested here. Depending on your needs, any of these options can help you connect your home lighting to more than just a wall switch.
