It uses double chip LEDs, which is much more efficient than conventional lights. These LEDs use two diodes which are protected by Zener protector. It prevents the diodes from burning. Another thing we loved about this light is that if one of the LED malfunctions, the whole system still works. However, it is not the same as other lights where the entire system shuts down.
As far as energy consumption is concerned, it consumes only 185 watts to provide output light 1000 Watts. This is a huge money saver when compared to HPS or MH lights. The lighting system offers full-spectrum, hence can support all stages of growth. We observed that it could cover a 3 x 3 feet area.
Another thing we loved is the controlled timer that allows you to control the lighting set up for different stages of plant growth.

Phlizon is another popular grow light that is actually very effective. When we looked at the light, it was little different than most of the lights we tested. Major difference was the absence of reflector.
Most of the grow lights are known to use a reflector to maximize the brightness or sometimes to just make them look beautiful. One thing that goes against the use of reflector is that it is non-heat resistant. If there is ashort circuit, at 80 degree Celsius there is a chance that reflector could melt.
As for the amount of energy it consumes, it consumes only 305 watts which is comparable to 800 watt HPS/MH. And the coverage area of it is around 3 x 3 ft when suspended at a height of 24 inches. Though we felt the coverage area is small, but the amount of light it offers and looking at the growth result you can hardly complain.

Most of the 1000 Watts are expensive. If you need something that doesn’t cost much that we would suggest getting Higrow Optical Lens series. We loved the way it is built. It uses a 90 degree optical lens that helps concentrate the light in much better way. Overall, it can reduce the light loss by 30 percent. It uses 200 LED lights that has 50,000 hours of life span.
It is full spectrum grow light including UV and IR to support all stages of growth. In addition, you can control the lights using veg and bloom mode during different stages.
We also loved the fact that it uses the least amount of energy to produce maximum output. It consumed only 410 watts to provide effect of 1000 watts HPS or MH lighting systems.
We tried this light for 4 x 4 ft area and we had to use two lights to provide uniform light for all the plants. The height we maintained for the light was 12 inches. We observed there was no burning.
Buyer’s Guide- What To Consider?
Growth of a plant depends heavily on the right light. All the plants has specific requirements. And the light becomes an even bigger factor when growing plants indoor. This why buying the grow light for your plants is necessary.
There are several factors that you need to know while buying the LED grow light like spacing, spectrum, light control, energy consumption, budget, coverage area etc.
Let’s look at them one by one:
1. Coverage Area
When you grow plants outdoor, you don’t have to worry about the space. But growing plants indoor is a different ball game. In outdoor, you have the tsun which provide uniform light for all the plants where as indoor its your artificial light that has to do the job.
Artificial lights have their own capacity and coverage area. Hence, depending on the coverage area, you have to buy the lighting system.
When you are looking to buy a LED grow light, you have to be sure about the coverage area. You must know the coverage area in feet. Using a measure tape, measure the area of your small plantation.
If you know the area of plantation you will be able to choose the right to grow light. Most of the manufacturer offers the rough figure on the coverage area of the particular model. You can either get one light that covers the area or you can use the combination of one or two lights to cover the area.
Again, remember the manufacturers provide rough figures, so make sure you buy the light that has 20-30 percent more coverage area than you require. A good way to know more is to consult someone who has experience with the particular model.
There is a lot of science involved when it comes to the growth of a plant. If you want your plant to have dense leaves and flowers, the right amount of different spectrum of light plays a key part. The plant not only requires right amount of white, red and blue light but also requires the right amount of infrared and ultraviolet light. This requirement of different spectrums of light depends on the growth stage of the plant.
Hence, a light has to be powerful enough to ensure that offers a wide spectrum of light for maximum growth. The most of the lights we have discussed are full spectrum light which also include infrared and ultraviolet lights.
While buying the grow lights you have to make sure that light is full spectrum and includes IR and UV. In addition, to being a full spectrum, it also has switches for different modes of growth. Using these switches you can to right spectrum of light depending on the growth stage of the plant.
We also advice you to learn about the different growth stages of plant and how it is affected by a different spectrum of light. Simple google search will help you do that.
3. Light Control
As we discussed about how the LED grow lights must have switches that allow you to switch to the right spectrum of light according to different stages of growth, the control over the amount of light also plays key factor.
Plants don’t require a particular shade of light 24 x 7. If you see the sunlight, the intensity of light changes through out the day. It is necessary for the plant to complete the cycle of photosynthesis effectively.
While growing plants indoor, the control of the intensity of light has to be done by you. Hence, the LED grow lights need to have that control to allow the plants to complete the photosynthesis cycle.
Most of the LED grow lights have veg mode and bloom mode, that allow you to control the light. Some lights may even come with dimmer to effectively switch to the right intensity of the light.
This feature is completely dependent on the grower and the kind of plant he or she plans to grow. VIPARSPECTRA UL Certified Reflector Series V300 and VIPARSPECTRA Reflector Series 600V are two great lights that provide you much better control with the light.
4. Energy Consumption
Using traditional grow lights could take a toll on your utility bills. Grow lights are used continuously for days, hence you require highly energy-efficient grow lights. And LED lights provide that efficiency.
Even though LED lights are known for their efficiency, still they use a high amount of energy. For instance, if you are looking for an output equivalent to 1000 watts, the LED lights are known to use around 600 watts for energy. The energy of 600 watts is still high. In addition to lights, there are other parts like a cooling fan that uses energy.
So overall, you require a lighting system that uses minimum energy to provide the desired output. HIGROW Optical Lens-Series 1000W is one of the most efficient lights that we tested.
When you are looking for a grow light, make sure you know how much output you desire. Once you know that you can compare the different models, that offer you the desired output with minimum input.
Like light, the temperature of the environment for plants is also crucial. Too much high temperature kills the plant and too low temperature also kills the plants. You have to maintain the the right temperature for the maximum growth of the cannabis plant or any other plant.
Any grow lighting system will produce heat. If such light is placed too close to the plant, it can burn the flowers. So to control that heat, most of the top LED grow lights use cooling fans. There can be either 2-3 cooling fans on the top. In addition to cooling fans, some models also use side vents.
During our tests, most of the grow lights were able to control the heat. However, we observed that if 2-3 lighting systems are used in combination, then an additional exhaust fans are required.
Most of the fans on our list have cooling fans. We also advise you to buy a grow light that has a well designed cooling system. And if you plan to use several lights in combination, ensure that you have an additional cooling system like exhaust fans or air condition in place to combat high temperatures.
You have to admit the fact that, using LED grow light is expensive. You not only spend money when you purchase it, but you also pay an electricity bill for the energy it consumes.
If you are on a tight budget, you have to calculate the cost as well as the energy bill. If you have only small amount of plants, you can go for the small capacity LED lights like VIPARSPECTRA UL Certified Reflector Series V300 or Advanced Platinum Series P300. These lights are not so heavy on energy bills.
However, you require a lighting system with a bigger coverage area, the budget could be an issue. You not only require a right amount of light but also that are cost-effective. For bigger coverage areas, 1000 watts are necessary. King Plus 1000w LED Grow Light is one of the most budget-friendly options that you can look for. It is all about knowing your requirements. Once you know your requirement you are in a better position to understand how much you must spend to fulfill it. You will get all types of LED lights and in different price ranges.
How We Conducted The Tests?
There are so many grow lights available in the market that buying the right grow light is almost confusing. Our aim was to give the LED grow lights that not only work but are durable and energy-efficient. We also wanted to gives lights for every kind of user because we know not all need large capacity lights or the most expensive lights.
We gathered 27 different models that were popular among the indoor growers. Our team then designed several tests based on parameters like capacity, energy efficiency, durability, coverage area, effectiveness, cooling, etc. We scored all the models based on the testes which allowed us to know the capabilities of each model.
Though the test gave us a good understanding of the lights. We wanted to know the products way a user with experience of using the product has. we also call it hands-on experience. We asked our team to handle the lights and use it the way a user does. This way they were more familiar with the process like use and installation of the light.
In addition to these, we brought in 8 experts from the grow light industry. Their expertise gave their insight on the manufacturing and several unknown facts about the models. Their expertise also helped us to design the right tests for the models.
After looking at all the information on each model of grow lights our team score the models on efficiency, effectiveness, and ease of use. This way we were able to create a list of the top LED grow lights for different types of users. Here is the table that shows how each grow light scored for the different test parameters:

1. Why LED grow lights are better than traditional HPS or MH grow lights?
There are a lot of ways to provide light to plants. But as we mentioned again and again, for the best growth of the plan right lighting system is the key. Traditional HPS and MH were really effective but the issue with HPS and MH is they use a lot of energy. In the long run you may end paying bills that may even surpass the amount you paid to buy the lighting system.LED are modern daylights that use less energy to produce the same output that HPS or MH does. Most of the manufacturers provide the stats that compare the model to the equivalent to HPS or MH lights. This stats give you a good idea of how much energy you will save with the particular model.
However, to give you a general idea with LED grow lights you you save 70 percent of the energy compared to the equivalent traditional light.
2. Which light is better for small grow room?
If you have a small grow room that consists of 5-10 pots, then a 300 or 450 watts LED grow light is perfect. Such grow lights have coverage area around 2 x 2 feet. If the coverage area is bigger than that you require grow lights of 600 watts.
3. Which color is better for the growth of the plant?
Different colors are needed for the complete growth of the marijuana plant. For instance, blue is much suited for the vegetative stage of the plant and when you combine blue and red color, it is well suited for the flowering stage. Most of the LED grow lights come with both vegetative and flowering switch that automatically switch to the right color of the LED light.
4. How many grow lights are needed per foot?
During our tests, we found that a 32 watts light per foot at a height of 18-24 inches provide perfect light to plant. YOu can keep this number while buying the LED grow light.
Growing plants indoor require a lot of knowledge, hard work, and the right tool. The LED grow light is one of the most important tools among all. Hence, you must have the right knowledge about it before you go out and buy one. In this post, we have tried to provide the right and tested information on different variants of LED grow lights that actually work. With the knowledge provided by us, all you have to do is decide what do you want to plant, what is the size of your grow room, how many plants do you own and what are your plans to expand the room in future.
Based on your requirements, you have to decide how much you can spend. The requirement and budget will help you narrow down the models that suit you. If you want more information on the model you decide to choose, always contact the manufacturer before buying.
