The Electric Sky 300 is designed to cover a grow area of 3 by 6 feet. Like any LED grow light worth your money, it offers wideband spectrum, enough to cater to your cannabis growth needs from seeding to harvest. Those aren’t the only reasons I vouch for this product, however. Here’s a closer look:

Features

Dual Direction Linear Optics

The Electric Sky 300 uses revolutionary technology to direct light away from your eyes and onto the plants (where it is needed most). It has a large footprint to distribute the illumination evenly across the tent. The ripple effect is that your cannabis grows uniformly with no dead or burned out zones. Be sure to hang the light at a height of 12 to 15 inches for the best results.

Super Silent Operation

Indoor growing means that you can place your tent anywhere — including your balcony, garage or any other space. You should, therefore, choose a lamp that is reasonably quiet — and that’s precisely what you get with the Electric Sky 300. It comes with full-body heat sinks that remove unwanted noise and heat. Growers say that this unit is barely warm even after hours in operation.

Fast Results

The Electric Sky 300 thrives on efficiency. It works really well for blooming and vegetative growth phases while using half the energy compared to HPS and standard lights. No more scaling power bills.

VIPARSPECTRA has perfected the art of making stellar LED grow lights for more than 10 years. The innovation embodied in their lamps is incredible, and this lamp is evidence enough. It will make a great choice if you’re a medium-sized or commercial grower.

Features

Wide Coverage

The VIPARSPECTRA PAR1200 is one of the most powerful grow lights on this list. It will provide coverage of areas 4 by 4 feet for the vegetative phase (at the height of 40 inches) and 3.5 by 3.5 feet during flowering (at the height of 36 inches). More than that, it uses a mere 534 watts of power, with a performance equivalent to that of a 1000 watt HPS model.

Perfect PAR/Lumen Output and Coverage

Remember when I said that the best LED grow light is all about providing enough lighting throughout the entire growth period? Well, the PAR 1200 design enables it to offer illumination based on the phase of growth your cannabis is going through at any particular time. That’s what I like to call a “hang and forget” type of light – literally.

Dimmable Function

Sure, the VIPARSPECTRA PAR1200 provides full band spectrum – but it makes it even more exciting. Tucked at the back of the light is a switch that allows you to fiddle with the illumination to match your plants’ needs at a specific time – whether vegetative or flowering.

The King Plus 1200w is a well-thought-out LED grow light. First, it consumes about 235 watts of power per hour. Now that’s an energy efficiency level any grower will appreciate, especially if you’re a starter with a limited budget for utility bills. Here’s what else makes it worth your consideration:

Features

Super Bright Illumination

The King Plus 1200w uses 10-watt double chips. What this means is that this light is brighter (and more efficient) than the standard 5-watt and 3-watt LEDs. By extension, you don’t have to worry about this unit’s ability to provide illumination for your marijuana.

Full Spectrum

Yes, the King Plus 1200w is the only light you’ll need to install in your tent. Its band of light includes white, red, blue, yellow, UV and IR. Of course, this is the closest you can get to natural sunlight. Plus, this is what your herbs require for all growth stages.

Efficient Cooling System

The King Plus 1200w has a 3.0 mm thick LED board (in comparison to 1.6 mm with standard lights). It also has glass convection with fans for efficient heat dissipation. Moreover, the diodes work separately, so this prevents the entire lamp from breaking down in case one or two bulbs burn out.

The Advanced Platinum P600 is an excellent LED grow light if you have the money to splurge on it. With the lofty price tag comes a five-star performance to match. Ideal for commercial growers, this thing offers 2 to 3 times the light intensity when compared to most models – and that’s not even the best part:

Features

12-Band Spectrum

Unlike most lights in its category, the P600 offers up to 12-band spectrum with IR and UV depths. Now for those who may not be aware of it, this is the most efficient and complete spectral output that you can get with any light. The ripple effect is better growth and a bumper harvest.

Selectable Veg/ Bloom Switch

You can determine how the P600 works based on the growth stage of your plants. This lamp comes with a built-in switch that allows you to toggle between vegetative and flowering settings conveniently. Meanwhile, the four-speed quiet fans combine with the upgraded aluminum cooling sinks to keep the heat at bay.

The SS550 by California Lightworks is a high-end unit, and arguably one of the best LED grow lights for cannabis in medium to large-scale farming scenarios. More than that, it is also one of the most powerful models in its class. Here’s a closer look:

Features

High Power LED Emitters

The SS550 SolarSystem comes with 88 high power LED emitters with a combined nominal power of 440 watts. This output level makes it suited for commercial cultivation of marijuana. Keep in mind that you need a powerful lamp to give the best possible results if you’re cultivating cannabis on a large scale.

Supplemental UV-B Bulbs

Like most models on this list, the SS550 SolarSystem allows you to move between veg and blooming settings easily. That way, you can obtain a lush growth. It is the ability to optimize the light intensity with greater precision that makes this lamp genuinely unique. More specifically, you can turn on the supplemental UV-B mode to develop higher potency a couple of weeks before harvest time.

90 Degrees Jewel Optics

The SS550 SolarSystem doesn’t have secondary optics. Instead, it touts 90-degree jewel quality optics for better canopy penetration. Further, its high photosynthetic photon flux (PPF) ensures that the light reaches the intended parts without wastage. And in terms of coverage, this unit can cover a grow area of 3 by 3 feet.

One of the best 1000 w LED grow lights on the market, the iPlantop comes with 2pcs certified cooling fans, with thermal silicone to keep it cool and quiet. It has 2mm holes on the panel for superior heat convection and dissipation. What does this tell you? Well, implies that you can leave the light running for hours without worrying that it will harm your plants.

Features

Daisy Chained Design

The iPlantop is a perfect option if you’re running a greenhouse or large grow tents. It allows you to connect more than one light at the same time to give you maximum coverage of 42 by 42 inches during the vegetative stage and 65 by 65 inches for blooming.

Triple Chips LEDs

The iPlantop uses upgraded, much brighter triple LED chips. Of course these are more efficient than single or dual chips and are scientifically designed to provide a balanced PAR/Lumen output. The long and short of it is that this lamp emits wavelengths that mimic natural sunlight with minimal adjustment.

Double Veg/Bloom Channel

The iPlantop goes beyond providing illumination during vegetative and blooming stages. It also promotes germination and photosynthesis, allowing your plants to develop foliage quickly. Besides, this beast can run for 14 hours per day, a handy function during flowering.

The best LED grow light doesn’t have to cost you hundreds of dollars. This one by BESTVA is one of the cheapest units on the market and a good choice for small tents. Make no mistake about it though – the affordability does not in any way mean that you’re compromising quality. We dissect its positive features here:

Features

Brand Exclusive Technology

The BESTVA 3000W uses 10 watt dual chips that make it remarkably brighter and more efficient than the standard 5 and 3-watt LEDs. For starters, this is the highest PAR/Lumen output per LED that you can find on the market.

Wideband Spectrum

The BESTVA emits light at an output of 1800 watts. It will provide enough illumination for your veggies, herbs, cannabis and other indoor plants, at all growth stages, all the way to harvesting time. How about the cooling system? Well, this lamp sports an aluminum panel and glass that allows it to operate at a temperature 60 degrees lower than other most units.

Its performance compares to that of 1200-watt HPS lamps.

You have got to love the Roleadro Galaxyhydro. A mid-priced option, this light offers up to 50,000 hours working time or an equivalent of 6 years on the job. Indeed, it is not the most durable unit on this list, but it isn’t the most expensive either, so it makes a good bargain especially if you’re on a tight budget.

Features

Intensified Spectrum

The Roleadro Galaxyhydro comes with up to 200 pcs of high powered 10 watt diodes, specially designed for flowering and initial growth stages. Reviewers say that this light improves foliage in two weeks, setting up your plants for a bumper harvest.

Timer Function

The Galaxyhydro is one of the few LED grow lights with a timer cord. In essence, this means that you can customize how it works, enabling you to leave it turned on for hours with minimal supervision. It is essential to note however, that this lamp doesn’t support daisy chain connections.

UV Function

The Galaxyhydro UV wavelength stops growth and spread of bacteria that may harm your plants’ development. It also provides the IR wavelength to encourage the vegetation and flowering phases of growth. The ripple effect is a better environment for more yields.

Reading through the LED grow light reviews is one of the easiest ways to know what to expect with a specific unit.

VIPARSPECTRA makes a return to my best LED grow light collection, this time with the TC1200. With a work time rating of over 10 years, this is one of the most durable models you can buy. It works for small and commercial growers alike. Here’s what makes it stand out when pitted against the closest competition:

Features

Perfect PAR/Lumen Output

Okay, here is the thing – a good LED grow light should provide a PAR output that matches your grow area. In other words, you’re better off with a lamp designed to deliver the best balance of wavelength in proportion to the size of your tent, and that’s what exactly what you get with this unit. Think of it as a way to help you achieve your maximum harvest.

Automatic Timer

You can leave the VIPARSPECTRA TC1200 running for hours with zero human attention. Sure, you can get that with most lights, but this one does you one better – it switches off automatically – so you only need to set the work time via the integrated timer. It also has a dimmable function to enable you to program Veg/Bloom brightness individually.

Large Coverage

The VIPARSPECTRA TC1200 1200w will give you a vegetative coverage of 4.5 by 4.5 feet hanging at a height of 32 inches, and 3.5 by 3.5 ft. coverage during flowering, swinging at a height of 24 inches. It consumes 530 watts of power, a performance that equals a traditional 1000 watt HPS.

The G8LED 900 deserves mention among the top rated LED grow lights. Ranked as the best LED grow light 2021 by HIGH TIMES magazine for two years in a row (2016 and 2017), this unit is on another level in every sense of the word.

The Marshydro Reflector 960W is a small LED grow light suited for beginners or people who don’t have a lot of money to spend. Despite the no-frills design, this is a full spectrum model with a switch to alternate between veg and bloom modes. That way, you can use it for your flowers, vegetables, and aquatic plants. Here’s what caught my eye:

Features

Unique Reflecting Blades

The Marshydro Reflector 960W uses special reflecting blades to help bring down consumption. When working at an optimum output, this lamp can give you the same results as a standard 1200 to 1300 watt HID light.

Safety-Oriented Design

First of all, this light is super easy to use – just plug it in and switch on. More than that, it uses a revolutionary design that separates the built-in circuit board and heat sink. The idea is to prevent damage of internal components in case of short circuit. Add the high-speed heat dissipating fans and what you get is an LED grow light that works perfectly without making any noise.

Auto Flower System

While the Marshydro Reflector 960W will provide lighting for all growth stages, it switches to the flowering system automatically when your plants start to bloom. It will provide coverage of 4 square feet and can handle the growing needs of many indoor plants including pepper, fruits, and marijuana.

The Phlizon 600W is yet another brilliant pick for budget growers. Its performance equals that of a 600- watt HPS at a consumption of 180 watts. With such a capacity, this unit can handle a grow area of 2 by 2 feet hanging at a height of 24 inches.

Features

No-Reflector Design

The one thing that makes the Phlizon 600W truly unique is the no reflector design. What this implies is that while this lamp isn’t so pleasing to the eye, it is heat resistant. Most units using the reflector design melt and get destroyed if a short circuit occurs or if the temps inside your grow tent hit anything above 80 degrees Celsius. Of course, this superior design translates to durability and by extension value for your money.

8-Band Spectrum

While the Phlizon 600W doesn’t offer the broadest spectrum, the 8-band wavelength is enough to promote your plant’s growth. It provides the universal red and blue IR with a white UV to enable your plants to develop resistance against diseases and encourages cell division.

Double Switch

Moving from vegetative to blooming stages shouldn’t be much of a problem thanks to the strategically placed switch. As for the penetration, you can hang this light at 90 or 120 degrees depending on what you’re growing. Its illumination extends up to 30 inches below the canopy.

Apollo Horticulture thrives on the simplicity of its LED lights. The company invests in research too, ensuring that their lamps can meet the demands of a modern grower. This unit is the brand’s most sought after in its line including six other models. Here’s a closer look at this unit:

Zero Heat Emission

You can suspend the Apollo Horticulture 700W considerably closer to your plants. In fact, this is one of the few LED grow lights that you can hang lowly inside your tent without having to worry that you might damage your plants, making it ideal for H2O and hydroponic systems as well as greenhouses.

Super Easy Installation

To get the most out of your LED grow light, you must install it correctly. Now this can be a challenge especially if you don’t know how to mount the light. On that front, the Apollo Horticulture 700W scores brilliantly. You don’t require balance to fix it into place. It even comes with aluminum hangers so you can start to use it right out of the box.

Impressive Durability

The Apollo Horticulture 700W doesn’t fall into the category of “premium LED grow lights.” It is a simple lamp with a minimalist design. Its durability, however, is quite something. This thing can last up to 50,000 hours or an equivalent of 5 to 7 years!

The MORSEN 3000W wraps up my Best LED Grow Lights roundup. This unit is for anyone looking for a versatile lamp that can handle the demands of various indoor plants, whether you’re talking about succulents, fruits, vegetables, flowers or cannabis. But versatility isn’t the only reason it appears on this list.

Features

Advanced Full Spectrum

The MORSEN 3000W comes with super bright 300pcs, 10-watt dual-band chips. More specifically, it has 236 red, 40 blue, and 16 white diodes. It also touts 4 infrared and 4 ultraviolet diodes, giving you perfect wavelengths for all growing stages including seeding, flowering and germination.

High Efficiency

The MORSEN 3000W can replace a traditional 3000-watt HPS lamp. But, that’s not the most exciting part. It also will provide the same performance while consuming as little as 560 watts of power! Other notable highlights include low noise operation and isolated power supply.

Why Do You Need The Best LED Grow Lights?

Sure, there are many types of lights for cannabis cultivation, but LEDs stand out. In fact, there is enough evidence to show that LEDs work better than any other type of grow lamps. To get the best possible harvest, you must create a perfect environment in which your plants can thrive. In essence, this means that the temperature inside your tent has to be just right – with no overheating. Top rated LED grow lights come with an integrated cooling system to control heat levels. Now this is an essential factor, mainly because you may have to keep the lights turned on for hours depending on the growth stage of your plants.

And, speaking of lighting hours, you might have to switch on your lights for up to 14 hours at a time. One of the primary reasons you’re better off with LED grow lights is their ability to save you money. More specifically, these lights consume less than 75% of the power used by other types of lighting. The long and short of it is that LED grow lights don’t use a lot of electricity and could very well be your best bet to cut down utility costs, — whether you’re a small scale or commercial farmer.

The best LED grow lights should provide illumination during the entire growth period. That means that when you install the lamp inside your tent, you don’t have to change it until harvest time. More than that, you can shift from one wavelength to the other based on the current growth phase. That way, you can be sure that your marijuana will progress through seeding, flowering, and vegetative stages correctly. Think of this as a way of helping you increase the harvest without spending too much. So there is more than one reason you should consider using LED grow lights over any other type .

Why use LED grow lights?

Of course, there are many types of lights for cannabis that you can hang inside your grow tent. But, before you opt for any other kind, kindly consider the following benefits of LED grow lights:

Energy Efficiency – You don’t have to worry about inflated power bills with LED lights. Many models use 70% to 90% less energy than standard lamps do. In fact, growers eager to save money are now shifting from HPS to the lower consumption LEDs. Indeed, these savings translate to more money in your pocket.

Durability – LED grow lights will last and last. Most units offer anywhere between 50,000 to 100,000 hours of working time. Now that’s up to 11 years of lighting. The only caveat is that you must ensure that you’re operating your lamp at an ambient temperature of preferably 25° Celsius and below.

Instant Light – You don’t need to expend much effort to get your LED grow lights to work. Just hang your unit above your plants, plug it into the power supply, switch it on and you’re good to go! Most units come with a steel hanger so you can position your lamp correctly after unpacking.

Full Growth Cycle – Any LED grow light worth your money should last throughout all the growth phases of your crops. It should provide enough lighting during the vegetative and blooming stages. That way, you don’t have to change the lights every time your plants transition from one phase into another.

Safe Lighting – LED grow lights don’t emit UV rays that can fade materials inside your tent. They don’t generate infrared either, a fact that helps keep insects and bugs away. By extension, this means that you will not have a lot of cleaning and maintenance to do inside and outside your tent.

Environmentally Friendly – RoHS certified LED lights don’t pollute the environment. You can hang them inside your tent without fear of damaging the local environment or humans and animals nearby.

Popular LED Grow Light Brands

Best LED Grow Light 2021 – Buyer’s Guide

Before you spend your money on any LED grow light, you need to ensure that it offers what you’re looking for. In other words, for you to enjoy the benefits of LED grow lights, you must choose the right model. Here’s a checklist and rundown of key considerations. Ask yourself:

Is the Light Sturdy Enough?

You may know how to choose the best grow tents, but you won’t reap the harvest you deserve if you pick the wrong light. At the very least, you need to be sure that the lamp you choose can serve you well for a couple of years. Imagine spending hundreds of dollars for an LED grow light, only to have it break down a few weeks later.

Any light worth your money should last for 10 years or more. The reality of it is that if you select a good model, you can concentrate more effort on other essential aspects of your plants’ growth, such as watering and so on.

Is the Brand Reputable?

As described above, some brands are better than others – that’s just how it is, even with other products. So check to see if the makers of the light that you plan to buy have created a good name and reputation within the industry. Check what real users have to say about the brand’s lights and their functions. Keep in mind that like most indoor grow equipment, what you see is what you get with LED lights.

Is the Light Energy Efficient?

At times, you may have to leave your LED light turned on for hours. In essence, this means that you will have to spend money on electricity. However, you don’t have to leave a hole in your wallet to sustain lighting in your grow tent. Good LED grow lights provide the illumination required without scaling up your utility bill.

Also, check to see if the light’s output is enough for your needs. Choose a model that has a capacity of 1000 watts or more. The more powerful a light is, the better the outcome will be (depending on the size of your tent of course).

How About Cooling Ability?

One of the mistakes to avoid when using LED grow lights is not ensuring that the temperature inside your tent remains constant. So pick a unit that has an excellent internal cooling system to help regulate the heat. You don’t want to burn your plants in the name of providing lighting for them.

It is always wise to invest in a model with a reasonable output – again, to match the size of your tent. Remember, while a lamp with higher output is powerful, it is likely to burn out more quickly. Replacing diodes now and then may prove to be expensive in the long run. You’re better off with an LED grow light that emits less energy and has an aluminum sink for heat dissipation.

Does the Light Have a Semiconductor Chips?

A semiconductor chip works by converting electricity to light. It is also critical for determining the wavelength. Look for a unit with 3-watt chips at the very least. Anything less than this may translate to insufficient illumination.

What am I Growing?

The LED light that you choose has to be suitable for the type of plants you’re growing. Sure, you can hang any model inside your tent, but some have special functions that cater to specific needs of certain plants. Make sure that you settle for a lamp that can provide the right wavelength for your plants as per their relevant growth phase.

How Big is My Tent?

When you grow weed hydroponically, you have to ensure that you develop an ideal environment for the plant to flourish. One of the easiest ways to do so is to use an LED grow light whose output is enough to provide enough illumination for your tent’s size. Measure the size of your garden even before you go scouting for lighting. Most indoor growing guidelines recommend that you find a unit that can offer at least 32 watts of power for every square foot, if you’re growing cannabis.

Does the Light Offer a Full Spectrum?

You need an LED grow light that can provide illumination for all growth stages. It has to emit different wavelengths for processes such as photosynthesis, flowering and so on. That way you don’t have to keep changing the lamp at the various growth stages.

What are Growers Saying About the Light?

The best LED grow light has lots of positive vibes from growers. In fact, at times all you need to do is to read LED grow light reviews to know what to expect with a specific model. Of course, you’re better off with a unit that has attracted high ratings and good feedback remarks from users. Make sure that you investigate the downsides of each model as well to understand the shortcomings of the light you plan to purchase.

Conclusion

LED lights are the new indoor growing phenomenon as marijuana legalization continues across many states and Canada. With this new commercial marketing wave comes the need to be careful when choosing your light so that you can set yourself up for the best possible harvest. I trust that this write-up has served its intended purpose – which is to showcase the best LED grow lights on the market and most importantly, help you narrow down your options.

At the rate these lights keep hitting the market, it is very likely that I will have to keep adjusting this list from time to time. So if I see any new model that I think needs to be included in this roundup, you will be the first to know. As stated earlier, I aim to make this guide a comprehensive resource for all things LED grow lights and cannabis. Feel free to reach out if you have any questions about the models featured here and I’ll be glad to get back to you as soon as possible. That’s all for now. Happy growing!
