The Cost of LED Grow Lights

The initial cost of LED grow lights is the only thing standing between you and a successful indoor garden. 

Generally, LED grow lights are more expensive than other grow lights, like incandescent and fluorescent lights.

Surprisingly, even though LED grow lights have a high initial cost, their durability and energy efficiency translates into significant long-term cost savings. 

Simply put, they use less energy and emit limited heat, thus lowering the overall energy costs. 

Also, the higher durability means you’ll encounter few replacement and maintenance costs. 

But you might be wondering, what’s the cost of LED grow lights? Today’s article answers this question and more to help you prepare to run a flawless indoor garden. 

Do LEDs Use A Lot of Power?

Not at all! We understand LED as energy efficient and among the least power-consuming lighting solutions.

 When you compare them with traditional incandescent, HID, or fluorescent lights, they’ll use less electricity to give you the same amount of light. 

Therefore, you end up not only paying less money for energy bills but also conserving the environment. 

However, the LED comes in different power ratings, and a powerful LED will use more power than a low-rating one. 

What Is The Cost of Buying An LED Grow Light?

The actual cost of buying LED grow lights varies considerably based on factors like wattage, size, brand, and additional features.

 But generally, expect to pay between $50 to a few hundred dollars for a high-quality LED grow light. 

The higher the coverage area and the more advanced features an LED grow light has, the higher the cost. 

To be honest, LED grow lights have a higher initial buying cost than other grow lighting options but with a lower long-term cost. 

Their high energy-saving properties and durability (low replacement) translate into lower operating costs. 

What’s The Cost of Running LED Grow Lights?

LED technology is energy-efficient, thus presenting a lower running cost than the other lighting options.

 But the exact cost of running them will depend on factors like the total electricity rate, hours in operation, and the LED wattage rating. 

We can estimate the total running cost of LED grow lights using the following formula: 

Total cost = LED wattage rating x operation length in hours x power rate in kilowatt-hours

For example, let’s assume you have a 200-watt LED grow light and decide to operate it for 12 hours daily.

 And if your power rate in kilowatt-hours is $0.12/kilowatt-hour, your total LED operating cost will be:

Total cost = 0.12/kWh x 200 Watts x 12 Hours = $2.88

This will translate into a total cost of $86.4 per month and $1036.8 per year. 

You can only realize how much energy cost you’ll be saving if you use other lighting solutions like incandescent and fluorescent grow lights. 

Factors Affecting LED Grow Light Cost

We have many factors affecting the cost of LED grow lights, and understanding them is critical to making an informed purchase decision. 

This section highlights these vital factors. 

Brand Quality

The price of LED grow lights increases with the reputation and popularity of the brand. 

Most of the time, reputable brands invest a lot of resources in quality control, research, and development leading to high-quality and excellent-performance grow lights. 

And while such high-quality lights might be expensive, their energy efficiency and low replacement cost translate into long-term cost savings. 

Size and Coverage Area

LED lights come in different sizes and coverage area specifications. 

Therefore, expect larger lights with bigger coverage areas to be more expensive than those with low coverage areas. 

But the benefit of buying a large coverage area grow light is that you won’t have to use many LED lights. 

Wattage Output

The wattage rating on an LED grow light will define its energy consumption and light output. 

Generally, a higher wattage rating translates into a high light output to your indoor plants.

 However, such lights are expensive and will also present more energy consumption. 

Spectrum and Light Quality

Manufacturers can design and tailor LEDs to emit specific light spectrums to support growth stages. 

Such LED lights with full or adjustable spectrum options are usually expensive owing to the complexity of their design and the multiple wavelengths they can support. 

Fortunately, investing in such LED lights will guarantee optimal plant light supply and, ultimately, better growth. 

Extra Features

Most manufacturers are developing LED lights with extra features like dimmers, programmable settings, and built-in timers. 

Therefore, you can use such extra features to improve your convenience and control the indoor gardening setting but at an extra cost. 

Energy Efficiency

Generally, LED grows lights are known for having a higher energy efficiency than the other options. 

But within the LED lights, some are more efficient than others, with the most efficient options costing more. 

Luckily, the most expensive LED lights also translate into higher long-term cost savings. 

Warranty and Lifespan

LED lights have a longer lifespan, which is advantageous since it means fewer replacements and maintenance. 

Also, some LEDs have a warranty covering potential issues and damages. Generally, an LED with a warranty and a longer lifespan will cost more. 

How to Lower Your Grow Light Costs

If you have just a few lights in your indoor garden, you won’t feel the weight of high energy bills. 

But when you extend your garden and increase the number of LEDs, the energy bill rises drastically. 

Below are approaches to reduce energy costs. 

  • First, check the LED grow lights you’re using, and if they’re less efficient, replace them with long-lasting and more efficient ones. 
  • Secondly, check if your locality has multiple electricity supply companies and switch to the cheapest option. 
  • Thirdly, we have some countries where electricity is cheaper during specific periods of the day. Therefore, take advantage of such provisions and use your LED lights more when power is more affordable. 
  • Moreover, running your LED lights throughout the day is unnecessary when indoor plants require only about 12 hours of light supply daily. Therefore, reduce the number of hours that your LED lights are exposed to light. 
  • Finally, use any available natural sunlight to complement your LED lights. This way, you’ll have to use little light from your LEDs. 


Are LED grow lights the best for cost saving? 

Yes! We consider LED lights the best option for cost-saving, especially when it comes to indoor gardening.

 First, these lights are more energy efficient than HID, incandescent, and fluorescent lights, thus translating into low energy consumption and high light output.

 And although their initial cost is high, their high durability and few replacements cover up for it. 

Is it expensive to run LED grow lights?

No! It’s not expensive to run LED grow lights; the only expensive thing is the high upfront cost. 

Generally, you’ll find it cheaper to operate LED lights than you would other options thanks to their high energy efficiency translating into low energy bills. 

Also, the lights provide more durability, thus presenting fewer replacements. 

How much does running a LED grow light cost a month?

We can’t place an exact value on what it’ll cost you to operate an LED grow light for a month. 

Generally, it’ll depend on several factors, including hours in operation, LED wattage rating, and total electricity rate. 

For example, if you have a 200-watt LED light operating for 12 hours at a power rate of $0.12/kilowatt-hour, expect to pay $86.4 monthly. 

Final Remarks

LED grow lights cost more than other grow light options but still present a lower operating cost. 

These lights will consume less energy than incandescent and fluorescent lights and produce more light. 

The cost to operate an LED light will depend on the operation hours, wattage rating, and electricity rate.

 And if you want to buy LED grow lights, keep an eye on the factors we have highlighted above to get the best LED at a reasonable cost.
