With the increasing popularity of indoor gardening, LED grow lights have become a popular choice for providing light to plants. LED grow lights are known for their energy efficiency and long lifespan, but many people are curious about do grow lights use a lot of electricity. Understanding the energy and power consumption of LED grow lights is essential for both home gardeners and commercial growers, as it can impact both energy costs and plant growth. In this article, we will explore the energy usage of LED grow lights and provide insights on how to calculate their electricity consumption.

LED Watts VS. True Watts of a LED Grow Light

When it comes to LED grow lights, it’s important to understand the difference between LED watts and true watts. LED watts refer to the amount of power used by the LED chips in the light fixture, while true watts refer to the actual amount of usable light output produced and actual power draw by the fixture. The relationship between these two values can vary depending on the quality and efficiency of the LED chips and the overall design of the light fixture.

A high-quality LED grow light will have a high efficiency rating, meaning that it will convert a large percentage of the energy used by the LED chips into usable light output. In this case, the true watts of the light will be close to the LED watts, and the light will be more energy-efficient overall. However, a low-quality LED grow light may have a lower efficiency rating, meaning that a significant amount of the energy used by the LED chips for power draw and will be wasted as heat instead of being converted into usable light output.

It’s important to consider both LED watts and true watts when selecting a LED grow light, as a high LED wattage does not necessarily equate to a high true wattage or a high-quality grow light. Instead, look for lights with high efficiency ratings and well-designed heat dissipation systems to ensure that you get the most usable light output for your energy usage.

Electricity Usage of LED Grow Lights

LED grow lights are an efficient and cost-effective way to provide light for indoor plants. The amount of electricity used by LED grow lights depends on the true wattage of the light and the number of hours it is used each day. To calculate the true wattage, divide the listed watts by 1,000. LED grow lights consume far less electricity than other types of lighting, such as incandescent bulbs. They are also more durable and last longer than other types of lighting.

LED grow lights are a popular choice among growers because they provide good-quality light without emitting excessive heat. They also allow growers to craft proprietary light formulas or recipes to bring out the characteristics of their plants. This can be especially useful for commercial growers who want to produce high-quality crops that will sell well in the market.

In addition to being energy-efficient, LED grow lights can also reduce other costs for growers. Without harsh radiant heat blasting plants from above, growers can use less water and fertilizer. They also allow growers to produce plants year-round while keeping costs down. Overall, LED grow lights are an economical choice for indoor plant growth that provides high-quality light while reducing energy consumption and other costs.

How to Calculate Electricity Usage of LED Grow Light

To calculate the electricity usage of an LED grow light, you will need to know the wattage of the light and the number of hours it operates per day. The wattage of theLED grow light should be listed on the packaging or in the product specifications. To calculate the daily electricity usage, simply multiply the wattage by the number of hours the light operates per day.

Calculating how much electricity your grow light consume is not difficult, you only need to know two things:

  1. The actual power of the light
  2. The number of hours the LED grow light runs per day

 We will use Mars HydroTS3000 LED grow light as an example to calculate the electricity it consumes. if you have a 450-watt TS3000 LED grow light that operates for 18 hours per day, the daily electricity usage would be 8.1 kilowatt-hours (kWh) (450 watts x 18 hours = 8100 watt-hours / 1000 = 8.1 kWh).

To calculate the monthly electricity usage, multiply the daily electricity usage by the number of days in the month. For example, if the daily electricity usage is 8.1 kWh and there are 30 days in the month, the monthly electricity usage would be 54 kWh (8.1 kWh x 30 days = 243 kWh).

Mars Hydro TS3000 grow light can replace a HPS grow light. Therefore, let’s see how that compares to an equivalent 600W HPS light:

The daily electricity usage: 600 watts x 18 hours = 10800 watt-hours / 1000 = 10.8 kWh).

The monthly cost of electricity usage: 10.8 kWh x 30 days = 324 kWh

It can be seen that compared with other types of grow lights, LED grow lights will save more on electric bill and money for you.

Calculating the electricity usage of LED grow light energy and lights is important for determining the cost to run a grow light and managing energy consumption. It is also useful for comparing the electricity usage of different grow lights and selecting the most efficient option. Keep in mind that the actual electricity usage may vary based on factors such as the efficiency of the LED grow light, the temperature of the growing environment, and the quality of the electricity supply.

How to Lower Your Grow Room Electricity Cost? 

If you’re growing plants indoors, reducing your grow room electricity costs is essential to ensure that your operation is sustainable in the long term. There are several effective ways to lower your energy consumption and lower your bills. First, consider investing in energy-efficient LED grow lights.
