LED grow lights are becoming increasingly popular as people look for more energy-efficient ways to grow plants indoors. But one question people often have about LED grow lights is whether they use a lot of electricity. How do you find out the answer to this question? In this blog post, we’ll explore the answer to the question: do LED grow lights use a lot of electricity? Stay tuned to learn more!

Do Led Grow Lights Use A Lot Of Electricity?

Led Grow Lights Use A Lot Of Electricity

LED grow lights have become popular in recent years because they are more energy efficient than traditional grow lights. You and your plants will benefit from LED lights because they use less electricity and produce fewer emissions of heat. Some people, however, remain dubious about the amount of electricity LED grow lights consume.

The truth is that LED grows lights use far less electricity than traditional grow lights. A single LED light can replace an entire fluorescent light fixture, using about one-tenth the amount of electricity. LED grow lights can save you a lot of money on your electricity bill.

Not only are LED grow lights more energy efficient, but they also produce less heat. This is important because high temperatures can damage plants and reduce their yields. LED grow lights produce very little heat, so you can keep your plants healthy and productive all season long.

How Much Electricity Does Led Grow Lights Use?

Electricity Does Led Grow

Several types of lighting can be used to grow plants in a controlled environment, whether that’s inside or outside. Grow lights are a popular option for plants that need more light than what can be produced by traditional artificial lights.

A wide variety of LED grow lights exist, each of which consumes a different amount of power. Ordinary incandescent light bulbs use about 20 watts per hour (W/hour), while high-intensity LED grow lights use about 100 W/hour. So if you were to turn on one high-intensity LED grow light for eight hours per day, it would use approximately 800 W over a month. Using just one high-intensity LED grow light will significantly reduce your electricity bill.

Traditional grow lights use a lot of electricity, but LED lights to use a fraction of that. For example, a 1000-watt HPS light will use about 1,000 kilowatt hours of electricity per year. At the same time, an LED grows light of the same wattage and will use only about 100 kilowatt hours. To put this into perspective, LED grow lights are up to ten times more energy efficient.

What Are The Benefits Of Using Led Grow Lights?

Benefits Of Using Led Grow Lights

There are many benefits to using LED grow lights over traditional grow light technologies, some of which include:

Energy Costs

LEDs use significantly less energy than other types of grow lights, meaning you’ll be saving money on your electricity bill.

Environmental Impact

LED grows lights use much less energy than traditional HID or fluorescent lighting, meaning they have a smaller environmental impact.

Growth Rates

With faster growth rates, you can prepare your plants for harvest sooner and avoid wasting time and resources.

Longer Lifespan

It is possible to save money over time by using LEDs instead of other grow lights because they last longer before needing replacement.

Faq About Led Grow Lights Use A Lot Of Electricity

Are Grow Lights Expensive To Run?

It depends on various factors, including the grow light’s wattage, the use hours, and the electricity cost in your area. However, grow lights are generally more expensive to operate than traditional incandescent or fluorescent lights. This is because growing lights emit more heat and require more energy to power them.

How Much Does It Cost To Use A Grow Light?

The price of electricity varies depending on where you live. In some areas, it costs more than 10 cents per kilowatt hour; in others, the cost is closer to 5 cents. If a grow light uses 1000 watts of electricity, it would cost between $10 and $20 to run it for a month.

How Many Watts Does Led Grow Lights Use?

LED grow lights consume less power than other grow lights, making them more energy-efficient. A typical LED grow light uses around 50-70 watts of power, compared to the 400-1000 watts that traditionally grow lights use. This makes LED grow lights more cost-effective in the long run, using less electricity and generating less heat.

How Long Do You Keep A Grow Light On?

The length of time that a grow light is kept on depends on the type of plant being grown, the growth stage, and the light’s intensity. Generally speaking, plants need between 12-16 hours of light per day to grow optimally. Some plants, such as succulents, can tolerate lower light levels and don’t need as much light as other plants.

Is It Okay To Leave Led Lights On All Night?

Avoiding LED lights all night is generally recommended, as they can produce significant heat. This heat can cause discomfort and, in some cases, overheating. Also, leaving LED lights on for an extended period can reduce their lifespan.


The amount of electricity used by LED grow lights depends on several factors such as the size of the grow area, the wattage and number of LED lights used, the duration of usage, and the electricity rates in your area. Compared to traditional HID or fluorescent grow lights, LED grow lights are generally more energy-efficient, as they produce less heat and use less electricity to produce the same amount of light.
