Before You Buy a Smart Light Bulb

Smart light bulbs are great, but they are not suitable for every situation. They work well with standard light switches, but they don’t work well with dimmer switches. Lessening the electrical flow to a smart bulb—as a dimmer switch does—can cause the bulb to wear out prematurely.

Check to see whether the smart light bulb you want needs a smart home hub to operate properly. If it does, the light bulb won’t work correctly on its own. Make sure the bulb’s connection is compatible to your setup, too. Wi-Fi can connect to a range of devices, but Bluetooth, Zigbee, and Z-Wave are more limited in how they interact with smart home devices.

What to Consider When Choosing the Best Smart Light Bulbs

Before choosing the best smart light bulbs for your home, learn the most important shopping considerations and some reasons to consider switching to smart light bulbs.

Type

Smart light bulbs come in four main types based on how they connect to your smart home system and phone.

  • Zigbee and Z-Wave smart light bulbs operate on a mesh network that can use smart home devices and a central hub to boost the network signal. This means each device extends the signal strength and range of the smart home system. Z-Wave and Zigbee are less popular than Wi-Fi and Bluetooth, so you will have a smaller selection of compatible components to choose from.
  • Wi-Fi smart light bulbs connect directly to your phone through your Wi-Fi router or through a central hub. Wi-Fi is the most popular method of connectivity used by smart light bulbs. Many smart home systems, like Amazon Alexa and Google Home, use Wi-Fi to link all their devices. If a large smart home ecosystem is your goal, Wi-Fi is the best option.
  • Bluetooth smart light bulbs are inexpensive because they are not designed to communicate with a central hub. Instead, these light bulbs pair directly with your smartphone or tablet for direct control over the lighting.

Brightness

A bulb’s brightness is expressed in lumens (lm), a measurement of the total amount of light visible to the eye. The more lumens produced by a smart light bulb, the brighter the light. The average lumen output for a smart light bulb is 800 lm, but choose the lumens based on how you’ll be using the bulb. You want more lumens for outdoor lighting, fewer lumens for soft indoor lighting. Pick smart bulbs and other types of light bulbs based on your light needs.

Color

Some smart bulbs produce only white light; others can produce light in any color of the rainbow. Colored light is a good way to add atmosphere, but a bulb that can produce a lot of hues usually costs more. Both types of bulbs are dimmable.

Smart Home Compatibility

When picking the best smart light bulbs for your home, decide whether you want bulbs that tie into a smart home platform or bulbs that work directly with a smartphone. Bulbs that work directly with a phone are easier to install because you won’t have to link the bulb to a central hub. Just screw it in, download the app, and you’re ready to go.

If you’re more ambitious and want to achieve a smart home system at some point, go with a bulb that can tie into Amazon Alexa, Google Home, or Apple HomeKit. These smart home systems let you access, control, schedule, and configure all the smart light bulbs in your house from one location.

App Features

Basic smart light bulbs connect to your phone through an app, allowing you to control the bulb remotely by touching the screen. Using the app, you can schedule some smart light bulbs to turn on or off at specific times.

Some smart bulbs have built-in motion sensors that send a notification to your phone when the light is triggered, so you are aware of a possible intruder. Some smart lighting apps can use geofencing to track the GPS in your phone and turn on the lights when you are within a specific range.

Setup

It’s relatively simple to set up a smart light bulb. If it operates through your phone independent of a smart home system, just screw it in, download the app, and you’re ready to go. If you’re using it with a smart home system, most manufacturers will have detailed information on their website about how to use their product. If you are uncomfortable setting up smart light bulbs, look for a bulb that offers setup videos and tech support.

Expandability

Having a smart light bulb on your porch you can turn on as you pull into the driveway is great, but you can take it a step further by expanding your smart lighting system to include your entire home. To build a smart home system, you need smart light bulbs that can interact with each other. This allows you to turn on or off a group of lights at the same time.
