Before you buy an LED grow light, there are a few things to consider. It's important to know what kind of grower you are: whether you're an indoor hobbyist or looking for the most efficient and cost-effective solution possible. Knowing what size your area is will help with picking out the right bulb, too. There are many LED grow lights on the market that offer improved light spectrums and higher yields with better coverage than ever before so don't be afraid to shop around when finding the perfect fixture for your indoor garden.

LED (light-emitting diode) grow lights have become a standard for serious growers. They are ready to plug-and-play, can produce high yields with incredible energy efficiency, and last a long time without losing lumens while traditional or HID bulbs may need yearly replacement as they start to lose their brightness.

But one of the biggest reasons LED grow lights have become the choice for serious growers is the spectrum of light they produce. Full spectrum LED grow lights can make a huge difference in helping your plants grow to their full potential and yields. Red & blue spectrums are crucial, but infrared and ultraviolet spectrums are helpful and even essential depending on what stage of growth your plants are in since different wave lengths are needed to be taken into consideration to ensure maximum growth.

You’ll also want to consider how big of a footprint you need your LED grow light to cover. Every LED grow light will have an amount of space it can cover effectively, so it’s important to measure your grow space and the potential area your plants will cover as they grow very carefully. Then you can research and read reviews like this one for LED lights can actually cover the space you need efficiently and effectively.

Yet another thing to take into consideration when choosing the best LED grow light for you is durability and efficiency since it isn’t unusual for an LED grow light to run for 12-18 hours a day. When researching LED lights be sure to note the total output. The more light an LED light actually gives off, the bigger yields you should get, so choose the most powerful LED grow lights (within reason) for your grow space.

So as you can already see, it’s not enough for an LED grow light to be popular on Amazon; it has to be the best for your needs and your indoor garden. Our experienced staff of experts have done a comprehensive review of the available grow lights for 2021 and recommend these as the best LED grow lights option out there!

The NextLight Mega LED grow light is ideal for those who want to cover a large area with an efficient, but powerful LED grow light. The “Mega” in the name doesn't refer to its size; rather it's called "Mega" because of how much power and coverage this panel provides you!

The NextLight Mega doesn’t have separate settings for vegetative and bloom/flower cycles. It has the same coverage area as 1000W HPS, but with better spectrum giving it one of the largest coverage areas in its class! With 1650 umols per second and 2.6 PPF per watt efficiency, this might be your best bet when deciding on what LED to purchase next time you need more grow lights!

This powerful grow light emits a full spectrum, bright white light that's more like the sun so you can expect tighter internodal spacing and better overall quality. NextLight's full spectrum is easier on the eyes and delivers you plants the same sun-like qualities they love without the high energy requirements and increased heat.

The Mega Pro includes an onboard dimmer that allows you to dim the light to 0%, 25%, 50%, 75%, 100% or set to EXT for external use with NextLight Control Pro or NextLight Adapt Pro controllers.

The HLG 650R is a powerful, top rated LED grow light that can produce some of the highest yields possible for your growing environment. The 650R draws 630 watts from the outlet - enough to flower a 5' x 5' area or veg a 7' x 7' area. With its convenient dimmer, it can drop down to 60 watts as needed and thanks to this same feature you get increased control over how far above ground level your plants are being grown at different stages in their life cycle.

The HLG 650R's Samsung LM301H LEDs are capable of emitting 4000K spectrum with an incredible 1770 umol/s total output, and don't forget that this model also has maxed out blue and red wavelengths - all at hundreds of dollars less than comparable models on the market!

The Horticultural Lighting Group 650R was engineered specifically for those who want maximum plant growth without breaking your wallet. This innovative design features cutting edge LED technology from Samsung which gives off intense blue as well as maximized red wavelength making it more efficient than ever before and perfectly suited for professional horticulturalists as well as amateurs and enthusiast’s home gardens.

The Grower’s Choice ROI E720 LED grow light delivers efficient, high-quality results, offering some of the best coverage we've seen for a 5' x 5' grow space. The ROI E720 features 8 LED bars and provides excellent efficiency, distribution, and quality components! The integrated drivers make this fixture easy to set up - just unfold it, hang it up and plug it in.

When you want the best possible for your plants, Grower's Choice is the way to go. The GC-3K Full Spectrum LED diode provides an ideal spectrum that will bring both vegetative and flowering growth to new heights with efficiency comparable only by industry giants. Utilizing Osram 660 nanometer chips for peak photosynthesis, plants get exactly what they need to grow big and beautiful while having an array of diodes that can rival any other brand. From initial vegetative growth all the way through flowering stage, this light will be sure your plants are getting just what they need in order to thrive well into maturity.

The ROI-E720 can save as much as 40% on energy and can be dimmed to have just the right light output you need for your grow operation. With its full PAR spectrum coverage, it provides better canopy lighting than a typical HID fixture would provide meaning higher yields and healthier plants!

The optional, but highly recommended Grower's Choice Master Lighting Controller gives you the ability to set your own light cycles, for example. Settings such as these are great if you want more control over how much light your plants get and when they get it.

The Mars Hydro FC E4800 could be the best LED grow light in its class for those looking to maximize yields with an efficient light that provides more than enough light. It also allows growers a variety of control options with its adjustable bars that spread out the diodes along each bar from side-to-side to provide better distribution of light. The design was carefully crafted with smart choices like high diode counts which are then distributed evenly throughout the fixture so there's no wasted space - this innovative yet affordable LED grow lights will save you time and money!

The Mars Hydro FC series are the first bar array fixtures with adjustable bar positions. This is a feature that growers have been wishing for because many bar fixtures create hot spots in the middle - which means you get less light at one end and more on another, so it's more challenging to grow plants evenly without touching each other. But now, thanks to these new bars from Mars Hydro (which can move anywhere along their frame), this problem doesn't exist anymore! The arrangements suggested by Mars Hydro include two different configurations: One moves the bars away from the center towards both ends while still providing full coverage across all three sections; and another configuration pulls back some of those outside.

The FC E4800's LED driver mount is a sleek and elegant fixture, designed with durability in mind. It consists of two aluminum frame pieces that are light weight while providing stability at the same time. The driver mount has an adjustable width so that you can properly position the LEDs anywhere within its reach without worrying about them hanging out from their designated spot too much - even though they provide plenty of cable lengths should you ever need to do some repositioning.

One reason for the FC E4800's high efficiency is because it uses more diodes than most other lights. FC E series fixtures were made with 2016 diodes - so at 480 watts, there's about 4.2 watts per diode in the FC E4800! 3 diodes per watt is typically considered to be a good density. Some grow lights use fewer than 2 diodes per watt so the FC E4800's density is excellent by comparison, even including diodes with 5 different spectra. The full spectrum diodes are a mix of 2800-3000K 4800-5000K. They also include UVA diodes near 410nm, red diodes at 665nm and far-red diodes around 740nm.

The Mars Hydro FC E4800 LED Grow Light is designed for the highest yields of any compatible LED grow light. The foldable design allows it to be compact and easy to install, while its sturdy construction lets you know that this product will last a long time!

Innovation is the key to success, and Black Dog PhytoMAX-2 1000 Full Spectrum Plant LED grow light is no exception. The PhytoMAX-2 1000 offers bright, high-powered light to a footprint of 8' x 8' (vegetative) and 6.5' x 6.5' (flowering). It has an unprecedented size for any LED grow light on the market which almost guarantees healthy yields with its 5-watt diodes and impressive heat management capability.

The Black Dog PhytoMAX-2 1000 LED grow light distributes its light evenly throughout the coverage area so plants at the edge are able to receive just as much light as those located near its center unlike many traditional fixtures that create hotspots at the center of their coverage area while outer areas get less energy.

The Black Dog LED PhytoMAX-2 uses the highest quality top-bin LEDs that use 5 watts of electricity evenly. This helps to eradicate leaf burns and hot spots common in other less powerful lights, all made possible by a carefully designed layout with each diode providing its own uniform light for your plant’s optimal growth.

Using too much power to light up the LED of an indoor grow lamp reduces its lifespan. The Black Dog LED PhytoMAX-2 takes care of excess heat that it produces by transferring some into a heatsink, which allows for more efficient lighting and longer lasting LEDs.

The Black Dog LED PhytoMAX-2, with its proprietary Phyto-Genesis Spectrum, is designed to encourage plants to grow healthier and more disease resistant. This spectrum also contains UV-A light to help in increasing your plant’s production of trichomes but does not emit UV-B rays like other parts of the spectrum (near infrared - NIR). UV-A light increases levels of desirable, medicinal plant compounds without emitting any harmful ultraviolet radiation and boosting photosynthetic efficiency by making it easier for plants to absorb sunlight.

Additionally, the Black Dog LED PhytoMAX-2 features a single spectrum eliminating plant shock that happens when changing from blue LEDs to red LEDs and features one of the biggest heatsinks in the industry, which helps heat dissipate quickly and effectively.

The Black Dog LED PhytoMAX-2 is one of the most impressive grow lights on the market. This revolutionary LED grow light will make your plants thrive, keeping up their growth and development until they are ready for harvest.

The HLG 300L V2 BSpec LED Grow Light from Horticulture Lighting Group has an improved design for even more light coverage, making it a no brainer for this best grow lights of 2021 list. The 300L V2 BSpec is excellent for vegging but not suitable as a full growth cycle or flowering light. For a companion flowering LED with high PAR values, check out the HLG 300L V2 RSpec!

The HLG 300L V2 BSpec is an efficient grow light that features 2 high-efficiency QB 288 V2 Quantum Boards with 544 top-bin Samsung LM301B LED’s and 32 Osram deep blue diodes. The 300L V2 BSpec consumes only 250 watts but produces just as much lighting power as any standard 600-watt HPS system with no heat buildup from lower quality LEDs & ballasts; making them one of the most cost-effective units on the market today. The bulb life span on this product lasts for 50,000 hours before replacement which saves you time maintaining your lamps.

The 300L BSpec produces perfect full spectrum light but adds an extra boost in blue light that makes it dialed in especially for vegging. 3500K is ideal because of its abundance of red and orange, which are utilized during flowering to produce higher yields. The additional 470nm blue diodes provide a vegging boost that maximizes growth before the final flowering stage begins with lower wattage than other LEDs while producing even more quality harvests!

What are Quantum Board LED Grow Lights? It is no surprise that grow light technology evolves with time and Quantum Board LED Grow Lights are a perfect example of this. Quantum Board lights are basically diodes attached to a board that allows for a fix to the one big problem COB lights have - limited spectrum (a common issue among other types as well). The broad spectrum offered by quantum boards helps to ensure plants receive all the light and nutrients needed to thrive, making it an excellent option for growing things like medicinal herbs or vegetables without any need for extra heat sinks!

The NextLight Veg8 Pro is a high efficiency LED grow light that will keep your plants healthy and thriving. The Veg 8 Pro comes with the power to outperform any typical fluorescent 8 tube T5, saving you time and money by eliminating the need to replace bulbs often or worry about excessive heat.
