Smart Bulb vs. Smart Switch: Illuminating Your Choices


When building a smart home, the terms “smart bulbs” and “smart switches” are often treated as interchangeable.

However, this is a common misconception. While they contribute to home automation’s convenience, the two technologies serve different purposes and require different planning strategies.

Proper planning for your smart lighting system is critical because it affects cost, electrical work needed, adaptability, and how well these devices will integrate into your existing smart home ecosystem.

This comparison aims to help you understand what each technology offers so you can make an informed decision based on your specific needs.

Smart Bulb Pros and cons


  • Cost-effective initiation:

When I first delved into the world of smart home technology, the thought of cost was a bit daunting.

However, I was pleasantly surprised to find that smart bulbs can start at as low as $10 per bulb.

This makes them feasible solutions for someone just starting out or those working with smaller setups.

  • Easy installation:

My experiences trying to install new technology have not always been smooth sailing, but the process couldn’t have been easier with smart bulbs.

It’s as simple as unscrewing and replacing the old bulb with the smart one. No extra tools are required!

  • Customization options:

As a creative individual, I loved the customization options available with smart bulbs.

They offer RGB colors and adjustable white color temperature, allowing me to modify the ambiance of my space on a whim.

Additional features: Smart bulbs include motion detection and Bluetooth connectivity, adding a futuristic touch to my humble abode.


  • Cost escalation:

While smart bulbs are relatively affordable, costs can add up quickly if you’re lighting a larger space.

When I expanded my setup to more than 5 bulbs, I realized my cost savings were dwindling.

  • Limited size and base options:

With only A19 or candle shapes, the design options were a bit limited for my taste.

  • Compatibility issues:

I found out the hard way that smart bulbs are not compatible with existing dimmer switches, leading to some unwanted flickering in my living room.

  • Stand-by power requirement:

The most surprising con was that the wall switch always needed to be ON for remote commands to work, which took some time.

smart switch pros and cons


  • Remote control for non-smart bulbs: Cost-effective for existing setups

I found it incredibly economical to use smart switches, especially when I had several non-smart bulbs already installed.

The smart switch allowed me to control these traditional bulbs remotely, saving me the cost of replacing them with smart bulbs.

  • Centralized control: Manage multiple bulbs and fixtures connected to a single switch

One thing I adore about smart switches is the centralized control.

I have several fixtures connected to a single switch, and the ability to manage all of them together has been a game-changer.

This feature makes life much easier, mainly when leaving the house or going to bed.

  • Flexibility in bulb choice: Compatible with various shapes and sizes

I love to mix and match bulb shapes and sizes for different looks and moods, which is something smart switches handle wonderfully.

Unlike with smart bulbs, I had the freedom to use any bulb I wanted without worrying about compatibility.

  • Scalability: Cost-effective for larger spaces with one smart switch controlling multiple lights

When I moved into my larger home, I found that using smart switches was more cost-effective than using smart bulbs in every socket.

With just one smart switch, I could control multiple lights, significantly reducing my expenses.


  • Electrical installation: Hands-on process, requires disconnecting old and rewiring new switch

One of the downsides of smart switches is that they require hands-on electrical installation.

I had to disconnect the old switch and rewire the new one, which was a bit intimidating and time-consuming.

  • Higher initial costs: Both for the smart switch and labor for rewiring

Even though smart switches can be economical in the long run, the initial cost can be pretty high.

I had to shell out for the smart switch and hire a professional for the rewiring, both of which made a significant dent in my wallet.

  • Limited customization: No RGB or adjustable white color temperature without a dimmable bulb

As a creative person, I found the customization options with smart switches to be somewhat limited.

I missed the RGB colors and adjustable white color temperatures of smart bulbs.

They’re only available with a dimmable bulb, an additional expense.

  • Wiring requirements: Some switches need a neutral wire, which is potentially an issue in older homes

One unexpected challenge I faced was finding that some smart switches require a neutral wire.

This was not an issue in my new home, but it could be a significant problem in older homes that lack this wiring.

Making the Right Choice

Considerations for Smart Bulb Adoption

  • Cost Sensitivity

If you’re budget-conscious like me, you’ll find that smart bulbs can be a bit pricey, especially if you’re planning to outfit multiple fixtures or rooms.

I remember when I first started looking into smart bulbs, I was taken aback by the price.

But, if you’re only looking to add smart functionality to a few lights, it might be a more economical choice than smart switches.

  • Desire for Customization Features

For those who enjoy the artistic side of lighting like I do, smart bulbs offer a level of customization that smart switches can’t match.

With smart bulbs, you control the hue, saturation, and brightness of your lights. I fondly remember hosting a party with friends and setting the mood with different colors, which was a hit!

  • Tolerance for Potential Compatibility Issues

A word of caution, though. When I started using smart bulbs, I encountered some compatibility issues with my existing fixtures that required careful consideration and, sometimes, replacements.

If you’re considering smart bulbs, make sure you’re prepared to do some troubleshooting.

Considerations for Smart Switch Adoption

  • Existing Setup and Bulbs

If you’re like me and have a home that’s already equipped with several traditional bulbs, smart switches could be a way to smarten your existing setup without having to replace every bulb.

When I switched to a smart switch, I was able to control all the lights that were connected to that switch without having to change the bulbs.

  • Scalability Requirements

Another critical consideration is the scalability of your smart home project. I found that for larger homes or rooms with multiple fixtures, smart switches were more cost-effective.

With one switch, I could control multiple lights simultaneously, while a similar setup with smart bulbs would have required multiple individual bulbs.

  • Budget Constraints and Willingness for Electrical Work

Finally, it’s important to remember that smart switches can have a higher upfront cost.

Not just for the device itself but potentially for the installation.

I had to hire an electrician to do the rewiring, which was an added expense.

So, if you’re considering smart switches, ensure you’re prepared for some initial investment and electrical work.


Reflecting on my journey, I’ve picked up a few key points about both smart bulbs and smart switches.

The smart bulbs offer convenience, allowing you to change your lighting without leaving your couch.

However, they can encounter compatibility issues, and it’s essential to be prepared for some troubleshooting.

On the other hand, smart switches require an initial investment, including possible electrical work, but can be more cost-effective for larger setups.

They allow the control of multiple lights simultaneously without changing the existing bulbs.

In the realm of smart home automation, one size doesn’t fit all. Your choice between smart bulbs and smart switches should reflect your personal preferences, existing setup, scalability requirements, and budget constraints.

It’s vital to make an informed decision based on a thorough understanding of both technologies and their pros and cons.

My personal experience taught me that it’s not always about choosing one over the other. Depending on your needs, a balanced approach might be the best way forward.

Combining smart bulbs and smart switches can help you achieve optimal home automation.

After all, the ultimate goal here is to create a living space that’s convenient, efficient, and smart, catering to your unique needs and lifestyle.

So, dive in, explore, and discover the best balance for your home!
