Smart bulbs are a popular way to turn your home into a smart home. They connect to your device or hub via Wi-Fi or Bluetooth, allowing you to automate and control your lights remotely, and have the potential to save you money on utilities. According to a 2021 U.S. Department of Energy guide, smart bulbs use significantly less energy and can save an average of $225 per year. That seems like a good deal, especially considering rising utility costs.
That being said, there are plenty of reasons to stick with traditional light bulbs. They may be more energy efficient and seem convenient, but they have many drawbacks and reasons to worry. In some situations, they can cause more trouble than they’re worth, and there’s definitely something to be said for reducing the number of smart devices we have rather than adding more. From cost to safety, here are four reasons why you might want to skip smart bulbs altogether.
Smart bulbs are more expensive
Even though smart bulbs can save you money in the long run, that doesn’t change the fact that they have a much higher cost of entry. Each usually costs around $20, and if you want color-changing bulbs, you’re looking at upwards of $40 each. Adding motion sensors that turn lights on when you’re in the room and off when you leave adds another $25 or more per sensor. Compare this to LED bulbs, which are typically sold in packs where each bulb costs around $1.
There are much cheaper smart bulbs available, for around $5 each, but that doesn’t change the fact that the transition is going to be expensive. You’ll need to replace all the bulbs in the rooms you want to connect, which will be especially expensive if you live in a larger home. After all, it defeats the purpose if only part of your room can be controlled from your phone or smart home hub.
Smart bulbs can last for years, even more than a decade, just like LED bulbs. You may find the upfront costs worthwhile given the long-term savings, especially since you shouldn’t have to replace them very often, but price is far from the only reason to avoid smart bulbs.
They are less reliable than stupid light bulbs
Getting used to smart light bulbs can be difficult because the muscle memory of flipping a switch is hard to shake. However, your switch must still be on for smart bulbs to work. You can install smart switches, which are better than smart bulbs for automation in some ways, but that still leaves the problem of your light fixtures relying on a network connection. This is less of an issue with Bluetooth bulbs, which you can still control as long as your phone or tablet is working, but if you have Wi-Fi bulbs or those that connect to a hub via standards like Matter or Zigbee, they will disconnect if your connection is weak or lost. Some users have also reported problems getting their smart bulbs back online after power outages.
Smart home devices connected to a hub like Google Home or Amazon Echo are also vulnerable to any outages or issues with the service itself, like the one that affected many Google Home users in early 2026 for about 48 hours. Although your lights will usually operate manually even if there are connectivity issues, the problem remains that smart bulbs are not as reliable as normal bulbs which will continue to do exactly what you expect them to do as long as they have a power source and do not need to be replaced.
Privacy and security concerns
It may seem silly to worry about someone hacking your light bulb, but it’s much more serious than it seems. It’s not just that a hacker can turn your lights on and off: it could compromise your entire network. Several researchers have shown that smart bulbs are vulnerable to hackers, making them an attack surface that could be used to infect your network with malware and access your private and sensitive information. There are ways to protect your smart home from hackers, but it will still be a risk that doesn’t exist if you stick to regular light bulbs.
Even if hackers fail to reach them, your smart bulbs can still be used to collect data about you. Like everything else with an internet connection, telemetry data, usage patterns, and other information can be gleaned from your smart home devices. Using them therefore means creating more potential privacy issues in your home.
Additionally, you can also opt for the features currently offered by technology companies. Google recently introduced the MCP (Google Home Model Context Protocol) server, which allows AI agents to analyze and control your smart home. This is an optional feature limited to Premium Advanced subscribers, but it’s an example of the slippery slope that building a smart home can present when it comes to privacy concerns. Of course, all your other connected devices are also prone to the same issues, but it can be harder to justify taking that risk for something as basic as the light bulbs in your home.
Not everything has to be smart
Along the same lines, it is more than reasonable to ask why everything needs to be interconnected and online. In the case of smart bulbs, the obvious advantage is remote control. But smart bulbs aren’t just vulnerable to the same outages and bad actors as the rest of your smart devices: They compete more for bandwidth, which adds even more strain on your network. This also means that they are not ideal in homes without a strong and stable wireless signal.
We are constantly at the mercy of digital platforms and internet connectivity, and it’s no surprise that many are device fatigue. There has been a small resurgence in retro gadgets and analog technologies such as cassette tapes and “dumb” phones, due, at least in part, to frustrations with AI. Much of this comes from Generation Z, who are questioning the purpose and impact of the ubiquitous technologies that have accompanied their entire lives.
That’s not to say that anyone expects things like smartphones, social media, and chatbots to disappear, but it does put into perspective how absurd it is that “My light bulb is offline” is a legitimate phrase in the 2020s. While smart bulbs can save energy and help automate your home, they have obvious downsides that, depending on your perspective, might outweigh the benefits. At the very least, smart bulbs are a solution to something that wasn’t actually broken to begin with.
