In recent years, smart bulbs have become increasingly popular, and their appeal is easy to understand. They are user-friendly, function as promised, and serve as an accessible entry point into smart home technology. Plus, using voice commands like “turn off the lights” adds a fun, convenient element to home lighting.
Many people are curious whether smart bulbs consume more energy than standard LED bulbs. Given that they are equipped with more technology for smartphone and Wi-Fi connectivity, could they actually be less energy efficient? Let’s explore this further.
Do smart bulbs consume more energy than standard LED lights?
The short answer is yes. Smart bulbs typically use slightly more energy than traditional LEDs. While both types of bulbs consume a similar amount of energy when they’re on, standard LEDs do not draw power when turned off. In contrast, smart bulbs use a small amount of energy to remain connected to Wi-Fi or a hub.
A 2019 study indicated that even when a smart LED bulb is turned off via a mobile app, it still consumes some power. Among the 30 smart bulbs tested, 21 exhibited standby power usage of less than 0.5 watts, which aligns with guidelines set by energy efficiency programs.
How much extra energy do smart bulbs use?
Smart bulbs have minimal electricity consumption while in standby mode, although this can vary by brand and model. For instance, certain devices like the TP-Link Tapo are known to use about 0.2 watts while in standby, whereas Philips Hue has noted that many of their newer products consume less than 0.5 watts.
The yearly increase in your energy bill due to a single bulb’s standby consumption ranges from $0.35 to $1.30, depending on local electricity rates. For most people, this added cost is unlikely to deter them from switching to smart bulbs.
The US Department of Energy reports that standby devices account for approximately 5 to 10 percent of a household’s electricity use, with major culprits including microwaves, televisions, routers, and computers.
Can you save money in the long run?
Yes, you can. The extra energy consumed by smart bulbs is minimal, and the advantages they offer may well offset these costs. One major benefit is the ability to turn bulbs on and off remotely using an app or voice assistant, along with the option to schedule their operation. These features can significantly reduce the time bulbs are active. Many smart bulbs also support dimming, helping to further decrease energy usage.
Are there additional costs associated with smart bulbs?
There is one significant cost to consider that is not hidden — the purchase price of the bulbs themselves. Smart bulbs usually come at a higher price point compared to traditional LEDs. While standard LED bulbs typically range from $1.50 to $4 each, smart bulbs start around $6 and can go up to approximately $90, with the average price generally falling between $8 and $15 per bulb. Buying in bulk can help reduce the overall cost.
Do smart bulbs last longer than conventional LEDs?
Not exactly; the situation is a bit nuanced. Smart bulbs usually have a shorter lifespan compared to traditional LED bulbs, mainly due to the additional technology that can degrade over time. Standard LEDs often last between 20 to 40 years, while smart LED bulbs typically last around 15 to 25 years.
However, the advantages provided by smart technology may lead to more efficient usage over time, helping to mitigate the shorter lifespan.
