The 10 Best LED Grow Lights For 2020
Things to consider before buying
There are a couple of things you absolutely need to consider before choosing the best LED grow light:
1) Spacing: You absolutely need to ensure that you have an idea of the amount of space you want to cover with your LED lights. Each light has a maximum range of space that it can cover, and it’ll be important to understand the measurements of your grow space down to the centimeter. If you currently do not know what that is, you should find out now. After that is done, make sure you read reviews and feedback from others on the actual space that the LED light can cover (sometimes, products are not as advertised. shocking, I know).
2) Brand/Budget/Price: This will be important as the higher-quality lights typically yield the best results. If you are a beginner, you will likely want to start with a lower priced option to get your feet feet wet. If you are more experienced, it never hurts to go with the quality, higher-priced option. In addition, brand and quality of the light is very important. A good brand that has raving customer reviews, is almost always, a sure bet.
3) Spectrum: A full spectrum LED grow light will go a long way in terms of helping your plant growth. You’ll need red & blue spectrums, but also infrared and ultraviolet, depending on the stage. It’s important to have a powerful light, with different wave lengths to ensure maximum growth. The full spectrum yields are a bit newer to the industry, but they are certainly making headway to any good growers catalog. They run cool and don’t need any additional fans, they cost less overtime given the electrical savings, and the durability is second to none. It is highly recommended to purchase a full spectrum LED grow light. Most LED lights have a range of colors being emitted (full light spectrum) – the best lights offer the full range, including UV light.
4) Electrical Usage: Your LED lights will need to have durability and great electrical efficiency as well. A good LED light should be operating for at least 10-12 hours a day. When researching a good LED light, you’ll need to thoroughly understand what the total output is (1000w, 400w, 300w etc). The higher you go, the more powerful and more likely leads to less electrical usage (and more cost effective for you).
5) Light Control: Depending on the stage, you’ll want to ensure that your plants receive the proper amount of lighting (down to the exact hour). See a breakdown of the phases below for growing LED lights:
- Seedling Phase: 16 hours on, 8 hours off
- Vegetative Phase: 18 hours on, 6 hours off
- Flowering Phase: 12 hours on, 12 hours off
It’s extremely important that light cycles are followed to a tee as it can severely alter the growth and potency of your plants.
What else could you possibly need? Bonus:
Grow Tent: It’s definitely easier to grow when you have an enclosed environment that protects from outside forces and sunlight. You can also control the temperature a lot easier in a confined space. You may think that every grow tent is the exact same. wrong. There are different brands out there that have a higher quality tent with more openings (to provide easier access) as well as poles that are more durable. All of this matters, my recommendation for grow tent is this Apollo Horticulture Tent. This is the cream of the crop when it comes to tents. When we used this tent, we didn’t see any light come through. It’s easily accessible with access in the back and the front.
Reviews Of The Best LED Grow Lights on the Market in 2020
Editor’s Choice: BESTVA 3000W
Out of the hundreds of lights we’ve reviewed, the BESTVA 3000W definitely hits the sweet spot in terms of most bang for your buck. This light is priced modestly and runs very cool. It works great in different sized tents and the light spread is second to none.
These lights are made from China, but don’t let that fool you, they’re very powerful and work very well for any type of grow. The fans are extremely quiet. It’s recommended that during the flowering stage, you limit the use of this light to a 4×4 space in order to maximize for efficiency and light intensity. The design of this light allows for great light penetration and the set up is easy with minimal weight restrictions.
The new and improved Double Chips Series model features a veg/flower switch, so it’s better than some of the cheaper LED grow lights on the market. This LED grow light definitely shined during the flowering stage, the results that we saw were incredible. We were extremely impressed with this grow light, especially with the brightness (our plants were thriving).

Runner Up: King Plus 1200W Double Chips
These lights have great design and also have high PAR value across your canopy. King Plus is a relatively new player in the market, but they have come out swinging with this light. Featuring 10W Double Chips, which are brighter more efficient than traditional 3W and 5W LEDs, this lamp is scientifically engineered to keep the balance of the PAR & lumen output and coverage. It gives BESTVA a run for it’s money, beating it on $ / watt, but keep in mind you typically get what you pay for and you can expect the BESTVA to last longer.
Great for grow tents, a room, and greenhouses. This is also a great product for you if you want something that’s easy to install as it comes with everything you need (hangers, cords, carabiners).
Customers rave about how fast the plants grow and how potent they become. This light produces very high PAR at a very low wattage. Great for energy consumption and for the price, this light gets the job done.

Advanced Platinum Series P300 300W – Good For Beginners
For those who love the P600 but don’t have quite that large of a budget or size of a grow tent, the Advanced Platinum Series P300 is a great runner-up. This is definitely a more affordable LED grow light that offers many of the same benefits as the P600, but at around half the price.
Its coverage is about 4.5 feet by 3.8 feet at an 18-inch height, perfect for compact grow areas, or when used in combination with additional lamps for larger areas. This light panel effectively replaces a 400W HPS light, while only actually using 180 watts of power – making it an energy efficient alternative to a traditional light. It’s just perfect for the small home grower. Just as the P600 represents the higher end of the market, this is still a serious piece of equipment–practically a steal for the amazing coverage you get.
This is a system that has a great high PAR per Lumen output of any other LED grow light panel I’ve seen. What does that mean? Well it means the panel gives off about 2 to 3 times the intensity of other grow lights.
More importantly, it has an 11 band spectrum that gives your marijuana plants the most nutritional value including those needed from UV and IR. The light chips are all 3W LEDs, and as I’ve mentioned before, the best 3-watt panels have an additional lens to focus the light a bit more. This panel comes with a 60-degree lens and secondary 90-degree focusing lens to give more intensity for plant growth.
The chips in this lamp are also replaceable and another reason for the slightly higher price tag. This means you can always keep that 400-watt output, even when a chip blows. Just order the one chip and replace it when it arrives from the manufacturer. With a 5-year guarantee, PlatinumLED offers security to their customers.

Morsen 2400W Full Spectrum Panel – Highest Wattage
Morsen is a top brand and you are looking for top quality. These lights typically run bigger and more powerful than most other LEDs. These lights have low energy consumption and really run great no matter what stage of plant growth you are in.
It’s a very high quality product and trusted brand for a very good price (especially when you compare to more expensive options out there like California Lightworks). Can be used in house garden, pot culture, sowing, a greenhouse + more. This particular product comes with a free power cord and free hanging hook. The lifespan for this light is particularly long and runs >50,000 hours and you should be good to go with the 3 year warranty in case anything breaks. This is a very safe option as it is also 3x to 5x the efficiency than HID & HPS lights.

Apollo Horticulture GL60LED 180W – Most Trusted Brand
Everyone knows the Apollo brand. This LED light produces very little heat because of the compactness of the product.
The Apollo brands are typically lighter in weight and this light is easier to mount inside grow tents in particular. The price is very good for someone that isn’t looking to spend much but is looking for a recognized brand and quality.
This particular product has been known to provide great light no matter what stage you are in (veg or flower). The Apollo light will have enough lumens to do whatever your plant needs to do with little to no heat and easy installation steps for you to follow. Plants respond well and these lights consume less power with great durability.
When we tested this product ourselves, we did notice that the fan did error on the hot side (despite the fact that it has fans). This light does have a lifespan of
50,000 hours, but does lack a power switch – which can be an annoyance to some growers. What we have noticed is that this particular light is great for medium sized, simple set up.

Galaxyhydro 1000W – Low Budget Choice
The first thing comes to mind for this product is the price. For what it costs, you’re getting a great product that has high output and is durable.The intensity of the light is great especially considering it is very power efficient with great spectrum on the light. The fans on this light also help keep the temperature down dramatically and is great for a beginner indoor grower who wants to test a light at an affordable price.
The recommended height to plant distance is around 12”-50” depending on the growing stages. The item is light at around 5 pounds and is extremely bright given the size. This light may not speed up the growing pace for your plants like some of the more expensive options, but it’s perfectly serviceable.
Despite the fact that this light doesn’t offer the full spectrum setup, it is still great for growth (especially if you are a beginner doing a basic set up). You’ll need to purchase basic accessories that typically don’t come with the cheaper LED lights (timer).

California Lightworks SolarSystem 550W – Best Spectrum
California Lightworks 550W LED Grow Light definitely falls under one of the more expensive lights on our list, but this is one situation where you get the results you pay for. This particular unit comes in a bright red color – a stark change from subtly-colored light panels from other manufacturers.
The light is a bit more intense than those with 3W chips, as this uses 5W LEDs instead – 110 of them. The optics are all jewel-quality glass focused at 90 degrees. In addition, it has two 15W UV-B tubes to enhance growth at the flowering stages. This panel runs cool and quiet with its built-in fans, and it comes with a 3-year warranty. California Lightworks is always a very well-recognized brand in the LED community, so you can’t go wrong here.

Marshydro Reflector 1000W – Most Versatile
This light does not get loud nor does it get loud. When we tried this light, it exceeded our expectations, especially for an “inexpensive” light.
The brand has been around for a while hence why they are able to make the installation easy for just about everyone (they’ve been in business for over 7 years and are a well-known brand in the industry). This light was definitely one of the more energy efficient compared to some of the other lights that we tested (especially the cheaper ones). We used ours in a 3×3 canopy and it worked great as the light was able to penetrate all open space.
This light does have the switch so you can toggle between veg/bloom mode, making this one of the premier lights for compact spaces. It can also be used for medium-sized spaces, so it’s an extremely versatile. It has the full spectrum of blue, red, and white for the veg and flowering stages.

G8LED 900W MEGA LED – Best Longevity
This is a very highly lauded grow light with some of the best longevity we have seen in the LED category. G8LED has had many iterations and has been producing LED grow lights for 8 years. Many bloggers and review sites describe this light as the cream of the crop, and it has been awarded some high accolades by major publications.
These lights are for both vegetative growth and flowering and provide intense lighting for 24 square feet of canopy. The light emits low heat and requires low electricity usage. If you want to graduate from a beginner set up to a professional production, this is the perfect light for you.
You may think it is a high price tag, but the money you save through electricity costs and the durability of this light will get you a long way.
Oh and by the way? High Times rated this the best LED light of 2016.

VIPARSPECTRA Reflector-Series 450W – Best ROI For Small Grows
This is great bang for your buck. One of the lowest priced option of the bunch and great energy savings. With only 269 watts pulled from the outlet, the light is able to still give high PAR value (equivalent to a 600W HPS/MH) which will allow for very valuable savings after a few months, so you should be able to get your $ back soon.
These lights deliver 12 bands including 2 IR and 2 UV through optical lens to maximize the PAR per watt. The VIPARSPECTRA lights are great for the veg cycle and you should see results quickly with the brightness of the light. The lights themselves are very powerful, but don’t give off the same kind of heat as some of the other more expensive brands/lights on this list.

Frequently Asked Questions
How many watts per plant for LED Grow Lights?
The amount of watts per plant will depend on how you pack your and train your plants, determining how many square feet each plant takes up. As a rule, you’ll get the best yields with about 35 watts per square foot for LED, and 45 watts per square foot for HIDs. Keep in mind, this is that actual wattage pulled from the wall, which for led grow lights is usually a lot less than what the light is labeled. For example, an LED light that is labeled as 300W will typically pull only about 180W from the wall. Below is quick guide as a rule of thumb.
Watts per plant for growing with LEDs:
|Plant Size||HID-Equivalent Watts Per Plant|
|1 sq ft||35 W|
|2 sq ft||70 W|
|4 sq ft||140 W|
How far should LED Grow Lights be from plants?
While LED lights don’t run as hot as HIDs, they still put out a very high intensity of light which is great for yields but can also cause light burn for your plants if you’re not careful. To avoid light burn you want to make sure your grow light fixtures are far enough above the top of your plants’ canopy.
LED grow light distance from plant:
LED grow lights of different power ratings will perform best at different distances. Lower-powered lights such as a 250 watt LED grow light should be kept 12-24 inches above the top of the canopy. Mid-range lights such as a 600 watt or 900 watt LED grow light should be 14-36 inches from the top of your plants. High-powered lights such as a 1500 watt, 2000 watt or 3000 watt LED grow light should be raised to 24-36 above the canopy. Follow the chart below as a general rule of thumb. If in doubt, always keep LEDs further away.
LED grow light distance chart:
|LED Wattage||HID-Equivalent Wattage||Distance from top of canopy|
|250 W||150 W||12 – 24 inches|
|450 W||270 W||14 – 30 inches|
|600 W||360 W||14 – 36 inches|
|900 W||540 W||16 – 36 inches|
|1500 W +||1000 W +||24 – 36 inches|
What are the pros and cons of LED Grow Lights vs. HPS?
There’s a lot of debate among growers about whether HID lights (HPS and Metal Halide) are better or worse than LEDs. The truth is, one isn’t holistically better than the other, it just depends on your needs and priorities for your grow. Take a look at the comparison table below to help you understand what type of lighting is best for your grow.
Comparison of LED Grow Lights vs. HPS:
|LED Grow Lights||HPS Grow Lights|
|More energy efficient. LED grow lights can produce as much as twice the light output for the same power consumption.||Less energy efficient. HPS lights consume more energy than LEDs to produce the same light output.|
|Longer lifespan. LED bulbs last longer than HIDs meaning you have to replace them less often.||Shorter lifespan. HPS lights diminish in intensity faster than LEDS, and need bulbs replaced every 12 – 18 months.|
|Low heat output. LEDs run colder than HPS and require less ventilation maintain healthy grow room temp.||High heat output. HPS lights run hot and often require additional ventilation to maintain healthy grow room temp.|
|Good for closet or beginner grows. LEDs typically come as compact, all-in-one fixtures, making them better for small spaces and closet or tent grows.||Good for large or professional grows. HPS lights provide high-intensity/high-yields and versatility to swap out bulbs with MH to change spectrum between veg and flowering.|
|Higher up-front cost. LEDs typically cost more up-front, but save money in the long run due to longer lifespan and lower energy consumption.||Lower up-front cost. HPS lights are typically cheaper watt-for-watt, but this gap in cost has been closing.|
|Harder to shop for. The quality and specs of LEDs vary highly across manufacturers, requiring more research when you shop.||Easier to comparison shop. HPS lights have been around longer and are more standardized across manufacturers.|
For each light we reviewed above, there’s several comparable models from the same manufacturer that scale up or down in terms of wattage. If you like one of those lights, but the wattage on the one we reviewed just isn’t quite right for your grow, check the reference list below to see if there’s a model that better fits your needs.
