How Do Smart Light Bulbs Work?

Ask any smart home enthusiast how they got into smart home tech, and there’s a good chance they’ll say “smart lights.” Smart lights, also known as smart bulbs or smart lighting solutions, are cost-effective and simple to set up and use, making them the perfect smart home starter.

And they come with loads of benefits. From turning on lights automatically at sunset to potentially warding off intruders, smart lights are some of the most versatile smart home products out there.

In this guide, we’ll explain how smart lights work and how you can best utilize them to make your home smarter and more secure.

How Do Smart Light Bulbs Work?

On the outside, smart light bulbs are just like regular light bulbs. You screw them into the light socket, turn on your light switch, and voila! Let there be light.

The “smart” part, however, comes from their being connected to your smartphone or tablet. This connection can be either through Bluetooth, Wi-Fi, or some other wireless technology like Zigbee or Z-Wave. Some smart light bulbs can also have a hub that bridges its connection to your Wi-Fi router and other smart home products.

Thanks to their connectivity, you can achieve a number of home automations with smart light bulbs. You can turn them on or off remotely using a smartphone app, set schedules, or even link them to another device so they turn on when a trigger occurs. For example, you can set some smart lights to turn on when your door unlocks.

How Do I Set Up a Smart Light Bulb?

Setting up a smart light bulb is simple, because it doesn’t require any heavy-duty installation like drilling or rewiring. Instructions for each bulb may differ, but generally speaking, to set up a smart light bulb:

1. Plug in the hub. If your smart bulb came with a hub, plug the hub into your router.
2. Get rid of incandescent bulbs. Remove your old bulb and screw the smart bulb into the desired light fixture.
3. Visit the app store. Download the mobile application affiliated with the brand of the bulb you purchased.
4. Connect the bulb to the app. Pair the bulb with the mobile application.
5. Name your bulbs. Label the bulbs intuitively, like “bedroom night table lamp,” so it’s clear what bulb you’re controlling in the likely event that you pair several.

Where Can I Use Smart Light Bulbs?

You can use smart light bulbs anywhere you would use regular light bulbs, but they are best suited for table lamps and fixtures that are not connected to wall switches. In those situations, a smart light switch could be a better solution, potentially. Additionally, smart bulbs might not be well suited for lights like ceiling fans, because some smart bulbs, especially those without hubs, can be bulky.

What Are Smart Light Bulbs?

Smart light bulbs are lighting devices that you can control wirelessly via a remote.1 That way, you can control them from different rooms, or even set up different combinations of lights that differ based on the time of day.

Smart light bulbs last longer than regular light bulbs2 and are more energy-efficient, too. We’ll go into more detail on that soon.

Benefits of Smart Light Bulbs

Ease of installation isn’t the only thing smart light bulbs have going for them. Other benefits of smart light bulbs include:

• Lower energy consumption: Compact fluorescent lamps (CFLs) or light-emitting diode (LED) light bulbs reduce the amount of electricity needed; they use 25 percent to 80 percent less energy than traditional incandescents.3
• Long life span: The average incandescent light bulb has a lifespan of 750 to 2,000 hours, while LED smart lights can work for up to 50,000 hours.
• Security: Many smart light bulbs have motion-detection features and will turn on if someone enters the room.
• Light customization for color and brightness: You can change the bulb color and brightness, designing different “scenes” to fit your various moods.
• Scheduling: You can set up a predetermined schedule of when lights turn on and off.

Types of Smart Light Bulbs

There is a range of smart light bulbs with varying bulb shapes and base sizes. Each bulb has a code consisting of a letter and a number like A19,4 so you’ll want to pay attention to what type of bulb is listed as compatible with your fixture, whether that’s a table lamp or ceiling fan.

The most commonly used household bulbs are the A19 and the E26.

How Much Do Smart Light Bulbs Cost?

Smart light bulb costs vary based on the brand, if it’s for indoor or outdoor, wired or wireless, has a hub or not, and if it’s a lamp. The cheapest smart bulb on the market that we found is the Cree 60W bulb, which costs $2.24, while the most expensive option, the LIFX Mini Light Bulb can cost just over $60. In our analysis, we found the average cost was about $29.

Are Smart Bulbs Worth the Money?

Though there is an upfront cost associated with making the switch from regular bulbs to smart bulbs, smart light bulbs are a money-saver in the long run. Since the smart bulbs are LED, they are highly efficient and don’t use as much energy as incandescent bulbs. Further, scheduling your smart bulbs means that the lights are never on when no one is home. And, if by chance you leave them on accidentally, you can turn them off remotely, making saving energy super easy.

And with saved energy comes saved money! Smart bulbs can last between 15 and 25 years, as opposed to incandescent bulbs which only last around a year.

However, smart bulbs use energy even when the lights are off, because they are always connected to Wi-Fi.5 If you want to experiment with smart home appliances, smart bulbs could be a good introduction to see how you like smart living.

How Long Do Smart Light Bulbs Last?

LED smart light bulbs can last for up to 50,000 hours, while compact CFL bulbs can last for up to 20,000 hours.6 Both LED and CFL bulbs last far longer than incandescent bulbs, which last a maximum of 2,000 hours.

Will Smart Light Bulbs Be Obsolete?

Light bulb technology is evolving rapidly, and Americans are getting on board. It’s unlikely that smart light bulbs will be obsolete anytime soon,7 especially because incandescent bulbs are being phased out of households.8 However, as incandescent bulbs become a thing of the past,9 now could be a good time to think about switching to smart light bulbs, if you haven’t already.

What Do I Look For In A Smart Light Bulb?

There are quite a few features and settings to consider when choosing a smart light bulb. We’ve highlighted the most important ones below:

• Does it require a hub? Not all smart light bulbs require a hub, but if the hardware is built into the bulb itself, it will have a bulkier look.
• Different colors/color spectrum: This is the fun part of smart bulbs because you can choose from the full color spectrum. That means cool vibes without having to commit to a permanently colorful lighting landscape.
• Pairing abilities: If you use Amazon Alexa, Google Assistant (Google Home), or Siri (Apple HomeKit) voice assistants, make sure the technology is voice-activated so you can control the lights with your voice. Of course, you’ll need smart speakers like the Nest Mini or the Echo Dot With Clock.
• Design: Does the bulb look traditional, especially if it is going to be visible in your lighting fixture?
• How it connects: Typically, smart bulbs connect through Wi-Fi, though there are Bluetooth, SmartThings, Z-Wave and Zigbee-compatible bulbs available.
• Size: A19 is the standard bulb shape, and E26 is the most common base size for lamps. Make sure your bulb will fit in the lighting fixture you want to put it in.
• App features: Is it easy to set up schedules and different light scenes for larger smart lighting systems? Are there ads, and is it intuitive to navigate to the parts of the app you’ll need most? Be sure to check the app’s ratings in the app store to get a sense of how current customers really feel.
• Brightness: Brightness is measured in watts, and most smart bulbs are around 60 watts.
• Cost: Obviously, the bottom line matters. However, there are lots of options to find something that fits in your budget, considering that the lower end of the price spectrum is around $2 per bulb, while the higher-end bulbs will cost closer to $60.

• Scheduling features: The ability to schedule is a huge perk of smart light bulbs, so make sure it’s easy to do so via the device’s app.
• Geofencing: Some smart bulbs can connect to the GPS in your phone, so the lighting turns off automatically when you leave the home and turns on when you enter.
• Installation process: If there is a hub, you’ll have to connect it to your home’s router. However, installing a hub should not take more than 15 minutes.

Smart Light Bulb Alternatives

While we’re big fans of smart light bulbs, there are some alternatives we wanted you to know about as well:

• Smart switches: A smart switch controls the flow of power to a certain area and replaces a traditional wall switch. It connects to the internet, and you can control it through a mobile app or a voice assistant like Google Assistant. Installing a smart light switch is more of an undertaking than installing a smart light bulb, because you’ll have to access the hardwires in your wall. However, it is still possible to do without professional help. Plus, smart switches make it possible to use smart lighting for overhead lightings like recessed lights or sconces.
• Smart plugs: Smart plugs are adaptors that plug into existing wall outlets. Then, you insert a small electronic device into those adapters. You can control the plugs via a smartphone app, turning on devices remotely even if they’re not “smart.” Smart plugs work well to control lamps that are plugged in rather than hardwired, like a floor lamp.

In Conclusion

Smart home technology is the way of the future, and smart light bulbs are a great place to start if you’ve been curious about upgrading some of your appliances. If you find they’re not for you, no worries, since starter kits are a low-stakes purchase and don’t require complicated installation.
