Buyer’s Guide- What is an LED Grow Light?

In essence, a grow light, in general, is an electric light source that people use to help their plants grow. These grow lights are designed in a way that they can provide a light spectrum similar to the sun or the plants’ needs, allowing for healthier growth.

Thanks to grow lights, people are able to create an indoor garden and have better control over their plants’ growth stages. It’s important to note that some plants may need a particular grow light type depending on their needs.

While there are several types of grow lights, LED lights have been proven to be the most affordable and energy-efficient ones. LED stands for “Light Emitting Diodes,” and grow lights of this kind produce much less heat and provide a much wider spectrum of lights for your plants.

People often compare LED lights with HID bulbs, which are also another popular type of grow lights. While both of them are efficient, HID bulbs require frequent replacement so that they always work correctly. On the contrary, LED grow lights can last for many years without any problems.

What Are the Different Types of LED Grow Lights?

As mentioned before, there are many types of LED grow lights on the market, and you must know which one is more suitable for your garden. We’re going to provide you with an overview of how these products work so that you can have a clearer idea of what you can work with.

Light Bars

If you’re looking to expand your lighting footprint on your garden, these may be the way to go. Overall, an LED light bar comes with a single row of LEDs in different spectrums. Most of these products feature much less energy consumption than other products, and they’re often easier to install.

However, one downside to LED light bars is that they’re not as powerful as other products. If you’re planning to buy a light bar, you may be better off using it as a supplementary light. Otherwise, you may need to buy multiple bars to assess all of your plant’s needs.

Light Panels

LED light panels are the most common product type for growers worldwide. As the name implies, these products are composed of big panels with LEDs all over them. While you typically cannot use an LED light bar as your primary light source, you can use an LED light panel as your primary light since it’s more suitable for full state growth.

Some products include a driver and heatsinks to get rid of excessive heat, which is excellent news for your indoor garden. Additionally, these products typically feature full-spectrum lighting, meaning they’re effective for both the vegetative and flowering stages of your plants.

You don’t have to worry about longevity with LED light panels since they tend to last for years (and even decades, depending on the product). However, they’re the most expensive type of LED grow light you can currently find on the market.

If you have the budget to invest in an LED light panel, we suggest you go for these since they’re the most reliable ones you can find today.

Light Bulbs

In case you’re working with smaller plants, getting an LED grow light bulb may seem like an appropriate choice for you. Keep in mind that these products often come with a single bulb, meaning you may not use it as your primary light source (unless you buy a lot of them).

Some of the benefits of LED light bulbs include that they can easily fit a standard light socket, and you can use them to customize your light spectrum a bit. However, keep in mind that you may often require more than one bulb to achieve your desired results. 

What Are the Most Common Uses for LED Grow Lights?

There are many uses for LED grow lights. While you may use them for any reason you consider appropriate, here is a list of the most common uses:

General Gardening: This is the most common application for LED grow lights. In essence, people use LED grow lights to provide a supplementary light to natural sunlight in the case of outdoor gardens. On the other hand, people with indoor gardens may also use LED grow lights to optimize growth.

Algae: Some people use LED grow lights that work for vegging to produce algae since it’s currently used to produce bio-fuel.

Urban Farming: Thanks to LED grow lights, farmers can move their operations to different areas without any problems. It’s important to note that urban areas are typically not suitable for growing food, which is why some people go for LED grow lights to make up for everything they may be missing from rural farming.

Marijuana: Many home growers have been switching to LED grow lights since they’re much more energy-efficient than other light sources, which is excellent for marijuana plants. While LED grow lights may be a significant investment at the beginning, they make up for it by providing much more efficiency to the user.

What Should You Look for In a LED Grow Light?

There are some things you must consider before purchasing an LED grow light. Keep in mind that if you don’t choose the correct product for you, your plants may not achieve proper growth, meaning you’re losing your investment.

Thankfully, it’s not hard to understand what makes a good product for you or not regarding LED grow lights. If you want to know more about how you can tell each product apart, keep reading!

Power / Wattage

Generally speaking, LED grow lights work with two different wattage types: Real wattage and theoretical wattage. It’s important to note that LEDs don’t work at their full capacity all the time since that would shorten their life span. The “Theoretical” wattage is the capacity your LEDs would run at if they were running at full capacity, whereas the “Real” wattage is the capacity they’re truly running at.

While it may seem obvious, the more light intensity you’re working with, the bigger the yield you may get. However, this factor may vary slightly depending on some other factors we’re going to mention right now.

Light Intensity

Three different factors can help you measure the quality of your light, which are:

  • Photosynthetically Active Radiation (PAR)
  • Photosynthetic Photon Flux Density (PPFD)
  • PPFD/Watt Ratio

PAR represents the range of colors and wavelengths of light that your plants use for achieving photosynthesis. Generally speaking, plants use blue wavelengths for vegetative growth and orange-to-red wavelengths for the flowering stage.

If you want your plants to grow as efficiently as possible, you must go for an LED grow light that offers as many wavelengths of light as possible. Thankfully, most manufacturers work with these kinds of light, so that shouldn’t be a problem. 

On the other hand, some products allow you to switch between the wavelengths for vegetation and flowering stages, depending on what you need; this is perfect to save energy and optimize your plants’ growth.

PPFD is the one that measures light intensity since it determines how many light photons fall into the PAR’s range. Keep in mind that light intensity is vital if you want your plants to grow efficiently, so if you’re not working with the right PPFD range, you may not achieve your desired results.


As the name suggests, your LED grow light’s coverage area determines how much it can cover while providing enough light for all the plants involved. Keep in mind that all plants need more light in their flowering stage, meaning you may need to move the lights closer to them. However, doing this process can decrease the coverage area.

Make sure you chose a product that’s suitable for your current gardening space so that you don’t run into any problems in the future.

Cooling Systems

While LED lights produce much less heat than other light sources, they can still provide enough heat to damage your plants. In essence, you must go for LED grow lights with proper heatsinks or cooling fans so that you can disperse the heat accordingly.

High-quality products often come with efficient cooling systems, so you shouldn’t worry about that. However, other products don’t have a cooling system that’s adequate to the number of diodes they have, which can make them less efficient in the long run.


While it may not seem as important as the other factors, purchasing an LED grow light with a proper warranty is vital if you want to avoid future problems. Keep in mind that if a single LED fails, you cannot replace it; you would need to replace the entire fixture. 

As mentioned before, LED grow lights are often expensive, so if you’re going to make that investment, make sure you’re getting longer warranty periods too in case something fails.


Bottom Line

Choosing your first LED grow lights can be a difficult task. However, as long as you know what your plants need to grow efficiently, you’re more than likely to make a good purchasing choice.

Remember there are many products on the market today. While you don’t have to go for the most expensive choice to get results, you must ensure you’re getting a product from a reputable brand if you want to avoid issues.
