Do Smart Bulbs Use Electricity When Off

Smart bulbs have become increasingly popular in recent years due to their convenience and ability to be controlled remotely using a smartphone or voice assistant. But have you ever wondered what happens when you turn off your smart bulb? Do smart bulbs use electricity when off, or not?

In this article, we will explore the answer to this question and discuss the various factors that can affect a smart bulb’s standby power consumption. By the end of this article, you’ll have a better understanding of how smart bulbs work and how to minimize their energy usage.

How do Smart Bulbs work?

Do Smart Bulbs Use Electricity When Off

Smart bulbs are a type of light bulb that can be controlled remotely and turned on or off using a smartphone or voice assistant. They typically use Wi-Fi or Bluetooth technology to connect to your home network and receive commands from a corresponding app or device.

When you turn on a smart bulb using the app or voice assistant, it sends a signal over the Wi-Fi or Bluetooth connection to the smart bulb, activating it to produce light. When you turn off the smart bulb, the process is reversed and the light is turned off.

Smart bulbs often have additional features such as the ability to dim the light, change the color temperature, or set a schedule for the light to turn on and off automatically. These features are made possible through the use of specialized software and firmware that runs on the smart bulb itself, as well as on the device or app that is used to control it.

Do Smart Bulbs Use Electricity When Off?

Yes, smart bulbs do use a small amount of electricity when they are turned off. However, the amount of electricity used is typically very minimal and is not likely to have a significant impact on your energy bills.

It’s a common misconception that electronic devices, including smart bulbs, completely shut off and stop using electricity when they are turned off. In reality, many electronic devices continue to draw a small amount of power even when they are turned off, a phenomenon known as standby power consumption.

Standby power consumption refers to the energy that an electronic device uses when it is turned off or in a low-power state, but still connected to a power source. Standby power is necessary for certain functions, such as maintaining the device’s internal clock or allowing it to be turned on or off remotely.

Smart Bulbs Use Electricity When Off

One research by ScienceDirect found that a smart LED bulb that was turned off used about 0.2 watts of power. This is a very small amount of electricity compared to the approximately 60 watts that a traditional incandescent bulb uses when it is turned on.

It’s worth noting that the amount of electricity used by a smart bulb when it is turned off can vary depending on the specific model and features of the bulb. Some smart bulbs may use slightly more or less electricity when they are turned off.

Tips for Minimizing Energy Usage of Smart Bulbs

There are several steps you can take to minimize the energy usage of your smart bulbs:

Use energy-efficient bulbs

Look for smart bulbs that have an Energy Star rating or are advertised as energy-efficient. These bulbs are designed to use less energy and have a lower standby power consumption.

Unplug or use a power strip

When you’re not using your smart bulbs, consider unplugging them or using a power strip with an on/off switch to easily cut power to multiple devices at once. This can help reduce standby power consumption.

Use smart scheduling

Many smart bulbs come with scheduling features that allow you to set the bulbs to turn on and off automatically at certain times. This can help reduce energy usage by ensuring that the bulbs are only on when needed.

Use dimming and color temperature features

Some smart bulbs allow you to adjust the brightness and color temperature of the light. Using these features can help reduce energy usage by allowing you to use less light when it’s not needed.

Keep software and firmware up to date

Regularly updating the software and firmware on your smart bulbs can help improve their energy efficiency and reduce standby power consumption. Check with the manufacturer for information on how to update your smart bulbs.

By following these tips, you can help reduce the energy usage of your smart bulbs and make a positive impact on the environment.


In conclusion, the question of whether smart bulbs use electricity when turned off is essential for consumers looking to optimize energy efficiency in their homes. While smart bulbs offer advanced features such as remote control, scheduling, and voice command capabilities, they do require a small amount of electricity to maintain their connectivity and responsiveness even when not actively illuminating. This “vampire” power, also known as standby power, enables the smart bulb to receive signals from a network connection, such as Wi-Fi or Bluetooth, allowing it to react to user commands instantaneously. Although the amount of power consumed in standby mode is relatively low, typically a few watts, it can add up over time and contribute to overall household energy usage, especially when multiple smart bulbs are installed.

Furthermore, understanding and managing the standby power consumption of smart bulbs can lead to more effective energy use without sacrificing the convenience and benefits of smart home technology. Consumers can look for smart bulbs that are specifically designed to minimize energy use when off, or they can use smart home hubs that centralize connections and potentially reduce the need for each bulb to maintain individual network connectivity. Additionally, integrating smart power strips or energy monitors can provide homeowners with precise control and real-time data about their energy consumption, helping them make informed decisions about when and how to use their smart lighting to best effect. By considering these factors, users can enjoy the full benefits of smart bulbs while also aligning with energy-saving practices that reduce costs and environmental impact.
