Understanding Night Light Power Consumption: 1 Minute to Discover Energy Use of Night Lights

How much electricity does a night light use?

Many homeowners consider night lights essential for safety or ambiance, but the energy consumption of these small devices can be surprisingly low. To understand their usage better, let’s dive into the details of how much electricity night lights typically use and how this can impact your energy bill.

Most LED night lights use between 0.5 to 2 watts of power. If we take an average of about 1 watt for a standard LED night light, it translates to about 1 kilowatt-hour (kWh) of energy usage if left on for 24 hours. In contrast, incandescent night lights can consume around 4 to 7 watts, which can significantly increase energy costs over time.

Factors Affecting Night Light Power Consumption

1. Type of Bulb: As noted, LED night lights use much less energy compared to incandescent ones. If you are looking to save on electricity, investing in LED night lights is a wise choice.

2. Usage Duration: If you leave your night light on for a significant amount of time each day, even the small wattage can add up. For example, leaving a 1-watt LED night light on for 24 hours would cost you less than $1 a year, whereas a 7-watt incandescent could cost over $6 a year.

Are Night Lights Cost-Effective?

When considering placements like hallways, bathrooms, or children's rooms, the question of energy cost may arise. Fortunately, the efficiency of modern LED lights makes them a cost-effective lighting solution. Even if you decide to light several night lights around your home, their overall impact on your electricity bill will likely remain minimal.
