Top 10 Best LED Grow Lights 2021 – Reviews and Comparison

Top 10 Best LED Grow Lights

Grow lights are very new to the scene but they are also becoming more popular among the masses because of their efficiency and are very easy to use. These lights are useful at all growth stages of a plant and can generate more light per wattage as compared to the HID or fluorescent lighting. They also run cooler which reduces the power costs and any danger of producing flames in your greenhouse. Some of these grow lights come with little built-in fans, and they don’t need any additional ventilation.

There are plenty of choices available on the market when it comes to LED grow lights, but not all of them offer exceptional quality and optimal results. We have developed this guide to provide you with information on how to choose the best LED to grow lights for your growing room.

At 15.7” x 6.7” x 2.3”, it is smaller than most LED grow lights, which does affect the PAR and coverage area of this model. However, it is important to note that at 24 inches of height its PAR value is 260 which is ideal for germination in most plants. Das for coverage, depending on the setting, the Phlizon will cover between 2 ‘x 2’ and 3’ x 3’ of the crop area.

Pros

    • The use of full-spectrum makes it effective
    • Dual Chip LEDs
    • Ensures safety in terms of heat management
    • The Dual-switch feature caters to different stages of growth

Guide on Choosing the Best LED Grow Lights

Why do you need these LEDs?

These are capable of generating more light as compared to the HID and fluorescent lighting. Furthermore, these lights also run cooler as compared to traditional lighting. These lights are highly efficient in energy conservation, and they don’t contribute to increasing the indoor temperature of your greenhouse. Some of them are equipped with internal fans to keep them cool, and you don’t need proper ventilation.
When buying an LED grow lamp, you must also understand that the recorded wattage implies that you can replace it with a traditional light. For example, if the recorded wattage of an LED lamp is 300W, then this means that this lamp can replace a 300W conventional light while the original wattage will be around 140W.
The LED grow bulbs have small diodes with different wavelengths of colors, and they are instrumental when it comes to energy efficiency. However, there are different kinds of LED grow lights available on the market, and you need to choose only those that offer optimal productivity. Therefore, there are some critical points that you need to consider before buying an LED. All LED lights are not the same, and you need to understand your preferences and requirements as a grower too.

Eco-friendly

LED lights are 100% recyclable, and they are very eco-friendly. Furthermore, they don’t come with any toxic substances or elements such as mercury that are used in the traditional light bulb. These lights are 80% more efficient as compared to conventional sources. 

Longevity

LED lamps offer durability and endurance, and it is one of the most significant merits of this lighting option. These lights don’t use much energy and are highly efficient. These lights are capable of lasting more than 50,000 hours which means that you don’t have to do much when it comes to maintenance.

Ease of installation

These lights are very easy to set up because you only need to set them up and then plug them in to turn them on. The installation of the conventional lighting options has more complications when it comes to installation.

Generates less heat

The LED lights are known to produce less heat as compared to the traditional lighting options because it doesn’t consume much wattage. Less temperature is more suitable for plant growth, and it limits the risk of burning or drying out.

Small in size

These lights are small as compared to the traditional lighting options which make them very portable. These lights come in different size options that make them very versatile. Even if you have the smallest plant growth, you will find an LED light suitable for your needs.

Important points to consider before purchasing a top quality LED grow light

  • Choosing the best grow light depends upon your requirements and your budget. If you have a small-scale growing operation, then you should opt for a more affordable option and a bulb that is less wasteful. For commercial purposes, you need top-quality and highly durable light that is used in a professional environment.
  • You need to understand that there are different spectrums for different stages of plant growth. If you are growing a plant from seed to flower, then you will need a full-cycle LED grow light. The blue and red spectrum lights are useful if your plant has already germinated in natural light.
  • You should understand the needs of your plants. Some plant types need high light while others are good with low light as well. Check to see if your plant is sensitive to bright lights. If they are, then you shouldn’t spend money on lamps that will burn or dry out your plants.

LED Grow Lights FAQs

Q: What is an LED grow light and how does it work?

It is uniquely suited to plant growth, which is why they are mostly used as an alternative to sunlight for indoor crops. They do this by emitting light of the particular wavelength that is ideal for the growth of the respective plants. They are suspended on top of plantations where the area they cover can be adjusted by adjusting their height.

Q: Will Grow Lights help my crops grow better?

Yes. These lights give you much more control by allowing you to choose what spectrum you would like the output to be in based on the crop you are growing as well as the stage of growth it is at. As such they produce what is known as Photosynthetically Active Radiation that is meant to actively stimulate photosynthesis. On the other hand, conventional lighting systems tend to throw generic artificial light on the crop, which is undesirable for plant life. Secondly, unlike other lighting systems, LED grow lights also have low radiant temperatures, and therefore do not interfere with the microclimate that you create for your crop.

Q: Are LED grow lights durable?

Some studies show that LED lamps differ from other light sources HID or High-Pressure Sodium lamps, in terms of longevity, by a factor between five and six. To put that into perspective, the average LED lamp lasts for about 50, 000 hours, while an average HPS lamp lasts for about 10,000; never mind the output losses that occur in HPS lamps over time. To put that in an even clearer perspective, the average LED lamp will not need a replacement for more than six years, and in cases of good maintenance, this number can even go up to eight or nine.

Q: Can LED lights damage my crop?

No. One of the greatest fears about growth lights is that they might damage crops due to the heat they supposedly produce. For starters, LEDs, in and of themselves, do not get burning hot as HID systems do. In fact, at full intensity, they are merely warm and can easily be touched.

To add to that, almost all LED grow lights on the market these days employ sophisticated heating controls that not only limit their heat production but also make sure that ambient temperatures are maintained. Measures like using built-in thermal controls and heat sinks are all proven ways of reducing heat emission by LEDs to a practically negligible level.

Q: What is Lumen Output and how does it affect the functioning of my LED grow light?

The Lumen Output of any LED grows light is the measure of light it produces. More often than not, power output and Lumen output are correlated. High power output will mean a higher lumen output. However, scientifically, Lumen is the measure of the intensity of light that falls on the human eye. In simple words, it is the measure of the amount of light we see and not the amount of light that is being produced. In reality, the parameter that you should be paying more attention to is the aforementioned Photosynthetically Active Radiation or PAR produced by a grow light.

Conclusion

Having an indoor growing room will need a good amount of your time and money, therefore; you need to plan your expenses accordingly. There are a variety of points you must consider before you make your purchase decision.

You need to consider the type of plant you are growing, the size of the operation, its cooling requirements, and various other factors. Therefore, you need to think about your light carefully and according to your growing project.

There are plenty of options available on the market, but you have to keep an eye on your requirements and budget and spend accordingly. LED grow lights can help in saving energy and cost and these lights are better suited for any project as compared to traditional lighting options.
