The best smart light bulbs represent a foundational piece of any connected home setup. Most options go well beyond simply turning on and off with a voice command. Many smart bulbs will let you control the color or temperature of the light, to swiftly switch from a romantic pink glow to neutral white and back again. Voice assistants can even control some models, so you can say, “Siri, make the lights green in the living room,” then sit back and watch the magic happen. Most smart bulbs work just fine with existing fixtures, but you’ll want to choose the specific features that match your needs and space. And because LED lights have greater lifespans and energy efficiency and produce fewer emissions, making them a far more environmentally beneficial choice than incandescent lighting, using them is smart in more than one way. With a huge assortment of smart lights on the market, that can be tricky. That’s where this list comes in.

How we selected the best smart light bulbs

To find the best smart light bulbs, we first eliminated any models that would require more than a simple turn of the wrist to install, which means screwing, mounting, or multi-step installation. However, we did include one option for a complete smart bulb starter kit that consists of a hub, just in case you want to get a jump start on upgrading all the bulbs in your home. We also ensured that each bulb we selected had basic smart capabilities such as timers, color adjustment, and on/off scheduling. From there, we looked at bulbs with voice-assistant capabilities, special features like music sync and away from home control, as well as the ability to group bulbs together for scenes and presets. The writers and editors at Popular Science have also tested some of the options in real-world settings.

Things to consider before buying a smart light bulb

Simply put, a smart light bulb relies on a built-in internet connection to communicate with an app or voice assistant to control its LED array. Choosing a smart light bulb shouldn’t be an arduous task, but the sheer number of options and the technical language describing each unit’s specifications can make shopping difficult. We’ll break down the features you should look for before purchasing and explain a few of the most common terms while we’re at it.  

Efficiency, wattage, and lumens 

A typical incandescent light bulb has roughly 1,200 hours of life in it, operates around 60 Watts, and costs approximately $1 per bulb on average. While 1,200 hours seems like a long time, smart LED bulbs blow them out of the water with a 25,000-hour lifespan on average, operating at just 10 Watts. LED bulbs do cost more, about $8 a bulb, however with more longevity and less power usage, you can save money in the long run.

When shopping for efficient smart bulbs, you’ll frequently come across the terms Lumens (LM) and Watts (W). As you can probably guess from the above description, Watts measures energy consumption, a unit of power. The higher the number, the more energy the bulb uses.  For example, a 120W bulb uses exponentially more energy than a 10W bulb. Lumens describe the bulb’s brightness and, similar to Watts, the higher the number, the brighter the bulb. While Lumens and Watts measure different things, you can find a rough corollary between the two; in an incandescent bulb, 900LM typically requires 60W. In an LED / fluorescent bulb, 900LM requires just 15W of power. 

New, smart light bulbs emphasize lumens and come with an updated label developed by the Federal Trade Commission, so if you’re shopping in person, you can compare the Brightness in Lumens, Estimated Yearly Energy Cost, Life Expectancy, Appearance, and Energy Used. Many packages still offer an equivalent brightness rating in watts to make the transition simpler for people who spent decades buying incandescent bulbs.

Color 

If you’ve ever grabbed a selection of new bulbs only to screw them in and realize they give off a bright white tone reminiscent of a DMV waiting area rather than a cozy, warm living room glow, then you know how important it is to select the right color or hue. While Lumens measure brightness, they don’t measure whiteness; for that, you’ll need to look at the bulbs Kelvin (k) rating. Kelvin describes color temperature; 1000k is a reddish glow, 1900k is similar to a candle burning, 2700k is a warm white glow, 4000k is a neutral white, and 5700k is a cool, bright white similar to direct sun. The Kelvin scale goes all the way up to 10000k, which is a white, almost blue color. 

Beyond whiteness, many smart bulbs come with a host of other customizable color options that span the entirety of the rainbow. Some bulbs will quickly change via remote control, and others can be timed to change throughout the day; the possibilities are endless with literally millions of color options. Just keep in mind that oscillating color doesn’t always mean the bulb is capable of dimming, so just check the specs if you have a dimmer dial or switch attached to your fixture. 

Connectivity

You can still flick smart light bulbs on and off with a switch, but their real draw comes from their connectivity with an app or voice assistant. Before buying, consider your dream light switching system and shop accordingly. If you’re hoping to use a voice assistant like Siri, Alexa, Google Assistant, etc., make sure the bulb is compatible with your chosen platform. Similarly, if you want to control the bulb with your phone but don’t want to abandon a traditional switch completely, look for a bulb that comes with a wall-mounted button or think about purchasing an additional smart bulb dimmer. You should keep in mind that you’ll only be able to control the bulb remotely if the light switch has been turned on; it needs continuous power to perform any of its tricks (including turning off and on). 

Finally, many smart bulbs will require a special hub to enact voice-assistant control and additional features. Make sure you read the fine print if you’re thinking of purchasing to see what features are controlled directly from an app and what might need additional connectivity support. 

Special features 

Most smart light bulbs will come with an array of colored light to choose from, and all of them will have options for connectivity and control, but there are a few more unique features to be aware of.

Scheduling/timers will allow you to turn your lights on, off, or change color over a period of time or during a particular time of day. Some lights can even track when your phone leaves or returns home and turn off or on accordingly using location sensors and geofencing capabilities. 

If you really want to go above and beyond with smart light bulb special features, look for a Bluetooth or Wi-Fi-capable model that will allow you to sync with the music playing from your phone or computer. Lights will flash in time with the beat creating the perfect atmosphere for a raucous party or setting the mood for a lo-fi study session.

FAQs

Q: Do smart bulbs use electricity when off?

Yes, smart bulbs do use electricity when they are off. They are referred to as vampire devices because there is still a steady course of electricity they feed off of, even in standby mode. This is because the bulb is controlled by your phone or remote, as opposed to a direct switch, and in order to respond to on / off commands, the unit will need to draw from an electric current. However, smart bulbs are energy efficient, so even though they need a steady source of electricity, a few bulbs will only cost you a few cents per billing cycle

Q: Which smart light bulbs last the longest?

The smart bulbs that last the longest will have roughly a 25,000 – 50,000 hour lifespan, which is roughly equivalent to 18-28 years of normal use. There are more than a few models that will last this long, including the Philips Hue. Even the bulbs with a shorter lifespan still last 15,000, a substantial upgrade from the incandescent bulb’s 750 – 2,000 hour span. Of course, variables can come into play such as temperature and the condition of the electrical system in your home. 

Q: Can you control smart bulbs away from home?

Yes, many smart light bulbs can be controlled when you’re away from home. Most units are operated via an app and additional hub, so as long as the Wi-Fi in your home is on and functional and you have access to the app itself, you shouldn’t have a problem controlling them remotely. Many apps will even let you go room by room, so you can turn the lights on in the living room without any changes in the bedroom. Some will also come with “Vacation Mode,” randomly toggling certain lights on and off to give the illusion that someone is home, deterring intruders.  

Final thoughts on picking the best smart light bulbs

The best smart light bulbs will elevate your at-home lighting from mere on/off adjustments to custom lighting designed specifically for you. Before buying, check the bulb’s specs to ensure compatibility with your devices, including voice assistants, and check to see if you’ll need an additional hub for maximum control over special features. Smart bulbs are an easy, convenient way to have some fun while advancing the functionality of your lights.
