How Much Electricity Do Smart Bulbs Consume in Standby Mode?

Smart bulbs have become one of the indispensable technological products of homes in recent years thanks to the conveniences they offer. Users can remotely control these bulbs via phone applications, create detailed schedules, and operate them integrated with voice assistants. However, this advanced technology and continuous connectivity come with a small energy cost. While standard LED bulbs consume no electricity when physically turned off, smart bulbs continue to operate in standby mode to maintain their network connection. This situation raises questions in consumers' minds regarding how much smart bulbs will impact the electricity bill and the difference between them and standard bulbs.

It is a definite fact that smart bulbs always consume slightly more energy compared to standard LED bulbs. When illuminating a room, meaning when they are turned on, both bulb types consume a similar amount of electricity. The real difference becomes apparent when the user turns off the bulb from their phone. Even if smart bulbs stop emitting light, they draw a low level of power to remain ready for commands. An academic research study published on ScienceDirect in 2019 revealed that a significant portion of the tested smart LED bulbs exhibited a consumption of less than 0,5 watts in standby mode. Similarly, these devices that meet the requirements of the Energy Star program strive to maintain their standard mode efficiency in standby mode as well.

The issue that undoubtedly concerns consumers the most is what kind of impact this standby mode consumption will have on the annual electricity bill. According to Gelinek data and technology news, the power draw of smart bulbs in standby mode varies from manufacturer to manufacturer but is generally extremely low. A modern smart bulb consumes an average of between 0,2 and 0,5 watts of energy when turned off. This situation translates to an approximate impact of 0,35 to 1,30 dollars on the annual electricity bill when considering a single bulb. Although it shows minor variations depending on local electricity tariffs, this extra cost is negligible for most users and does not pose an obstacle to enjoying smart home systems.

When looking at the total standby mode (vampire power) consumption in homes, it is understood that smart bulbs are not the main factor to blame. According to data from the ABD Enerji Bakanlığı, all devices left in standby mode constitute about 5 to 10 percent of a home's total electricity usage. However, the largest share of this percentage belongs to larger devices that remain constantly plugged in, such as televisions, microwaves, internet routers, and computers. Therefore, although the contribution of smart bulbs in standby mode does exist in reality, it represents a very small percentage of the total hidden energy consumption in a home. If energy saving is targeted at home, focusing primarily on larger and power-consuming household appliances would be a much more logical step.

When evaluating the long-term use of smart bulbs, factors such as purchase cost and device lifespan must also be taken into account. While a standard LED bulb is offered for sale between 1,50 and 4 dollars, the prices of smart bulbs can start from 6 dollars and go up to 90 dollars. Additionally, because the Wi-Fi, Bluetooth modules, and other electronic components inside them wear out over time, the lifespan of smart bulbs remains in the 15-25 year range, unlike the 20-40 year theoretical lifespan of standard LEDs. Nevertheless, conscious use of features such as remote control, detailed scheduling, and dimming can prevent the bulb from unnecessarily turning on, enabling significant savings in the long run. As a result, although the standby mode electricity of smart bulbs may seem like a disadvantage, their potential to increase energy efficiency through the control mechanisms they provide is much higher.
