How much electricity will LED grow light cost? Many people wonder if LED grow lights can really save us a lot of daily electricity. LED grow lights will indeed cost you less on your electricity bill. As we talked about before, LEDs are more efficient and cost-effective than HIDs and CFLs, learn more about LEDs, HIDs, and Fluorescents.

If you are planning to invest in a batch of grow lights for your growing space, in addition to the cost of purchasing the grow lights, you need to factor in the operating costs, as well as the electricity the grow lights will cost. 

How to calculate the electricity cost of LED grow lights?

First of all, you need to know that the wattage of the grow light determines the amount of electricity you use. The higher the wattage of LED grow lights, the more power it consumes. The steps to calculate the electricity bill are：

1. Daily Power Consumption (kWh) = Power Consumption (kWh) x Number of Hours (h)
2. Electricity Cost ($) = Power Consumption (kWh) x Electricity Rate ($)

Please note that electricity costs are calculated in kilowatts per hour, so remember to convert the power unit to kilowatts when calculating kilowatt hours, otherwise you will get the wrong data.

Take Bestva BAT 600W LED grow light as an example, its actual power is 650W±5%, we take the value of 650 watts for calculation, first convert 650 watts into 0.65 kW, assuming that the LED grow light runs 18 hours a day. Then multiply these two numbers to get the daily power consumption.

That is: 0.65KW ✖️18h=11.7KWh

Next, you only need to know your electricity rate to calculate the electricity cost for LED grow lights. let's continue.

In 2022, the average electricity price in the United States will be 14.92 cents. You can enter your zip code to see actual electricity rates in your state: https://www.saveonenergy.com/electricity-rates/

So the daily electricity bill for LED grow lights is 11.7KWh✖️$0.1492=$1.75

We can know that the electricity cost is $52.50 for a month and $630 for a year.

Of course, this is just the electricity bill for one LED grow light. If you invest in 10 LED grow lights, then you need to multiply the number by 10 on this basis, that is, you need to pay $6,300 in electricity bills per year. And the number of LED grow lights you need to buy depends on the size of your space. 

Let me show you the estimated cost of electricity for Bestva LED grow lights:

How to save on electricity bills?

Run your grow lights during the time of day when your electricity bills are the cheapest. Some energy companies offer time-of-use plans that charge you based on the time of day you use the electricity. Fees are lower during off-peak hours and higher during peak hours. The exact peak and off-peak hours vary by provider, but off-peak hours tend to be at night or noon, while peak hours occur in the morning and evening.

Choose a more affordable electricity supply company. If your country/state has multiple electricity providers, different electricity providers have different pricing. You can check which price is more attractive. When considering a supplier, you should pay attention to this: fixed rate or variable rate? The fixed price remains stable for the duration of the contract, and the variable rate may change from month to month.

Choose high-quality LED lights to save electricity. LED grow lights consume far less power than an equivalent HID lights. In other words, LEDs use far fewer inputs for the same output.
