Best LED Grow Light Reviews 2017

There is no shortage of LED grow light reviews and buyer's guides scattered across the web.  Most are designed to help you on your journey of purchasing a new lighting solution for your indoor garden, but few encompass everything you truly need to consider before making your next purchase. 
Due to the explosion of the hydroponics industry over the last decade, there has been an increasing number of new manufacturers entering in the marketplace.  This has caused the market to become saturated with low quality LED lighting systems.  

Purchasing one of these low quality LED lights can end up costing you thousands in lost yields and unmeasurable amounts of stress.  This doesn't mean that choosing the perfect LED for your indoor garden has to be a stressful situation and by sticking with a reputable brand, you are guaranteeing yourself a certain level of quality.

The Advantages of a LED Grow Light

LED lighting systems are quickly replacing their outdated HPS and MH counterparts.  The reasons for this are simple.  One main reason is the fact that LED lighting is far more efficient than outdated high output lighting systems and switching to one can save you thousands in lighting bills.  Led technology has continued to improve and over the last 5 years LED lighting systems have now surpassed all other forms lighting for use in indoor gardening applications.  With the advent of full spectrum lighting solutions LED manufacturers now have the ability to more closely mimic the rays from the sun.  This gives your plants access to the light spectrum needed to create more energy during photosynthesis, resulting in higher yields and quicker growth rates.  Let's examine what makes LED's a smart choice.

Compact Design

LEDs are much smaller than HID lighting systems.  This means you can mount them in tighter spaces without restricting the height your plants can grow.  An average LED light is around 4" - 6" thick.  Compared to your average HID hood, this is a drastic reduction.  This also allows for growing on shelving systems and in grow cabinets.


Energy Efficient

There is no comparison to LED lighting in terms of energy efficiency.   A HID lighting system can use 3 times as much electricity to produce the same amount of usable light found in a full spectrum LED system.  This is because of the different ways these devices produce light.  A LED does not require a filament or a gas to be heated and as result, it requires much less energy to function properly.


Lower Temperature

One of the biggest advantages LED lighting systems have brought to the world of indoor gardening is their low operating temperatures.  A LED light can run cool enough to touch.  This opens up a lot of options in regards to where you grow and how tight of a space you grow in.  LED grow lights can function in cabinets, shelving systems, and closets without cooking your garden.   Heat is also one of the main contributors to odor.  If your grow room reaches 85 degrees your plant's oils are going to become agitated and produce more odor.


Most LED lights are rated around 100,000 hours of use. Whereas your average HID is rated around 20,000 hours of use.    This means you will go through 5 HID bulbs for every LED burn out you encounter.  HID bulbs lose their effectiveness after a couple grows, while LED lights are still in perfect condition.


How to Choose the Perfect LED Lighting System

Let's take a moment to examine how to choose the perfect LED for your needs.  LED lights allow you to grow in tight spaces without turning your indoor garden into an oven.  You will still need to evaluate the total amount of space you have to grow in and match your LED size accordingly to avoid over spending on more light than you need.  Choosing a light that is slightly bigger than your needs can give you the ability to upgrade your total grow space without having to reinvest into an additional light.  In most scenarios, you will need approximately 32 watts per 1 sq ft of grow space.  Here is a helpful table to use so you can get the perfect fit every time.

Garden Square Footage


2 sq ft (2x1) 64
4 sq ft (2x2) 128
6 sq ft (2x3) 192
9 sq ft (3x3) 288
12 sq ft (3x4) 384
16 sq ft (4x4) 512
20 sq ft (4x5) 640
25 sq ft (5x5) 800
30 sq ft (5x6) 960
Once you know what size LED fits your needs, you are ready to get started examining the quality and effectiveness that your potential light offers.  To do this you will need to check a combination of factors.  Each of these factors plays a crucial role in determining the overall performance of your LED lighting system.

The Right Spectrum

Your LED's light spectrum plays an important role in initiating your plant's life stages.  In most cases a multi- spectrum light can be ideal since it allows for you to effectively grow in both flowering and vegetative states.  An adjustable spectrum is the best option because it allows you to focus your LED on the best possible option to facilitate your plant's growth.

Blue Lights
When you plant is in a vegetative state it will require cool colors rated above 5000K.  This part of the lighting spectrum helps your plant's ability to produce leaves and roots during the vegetative stage.  If you are looking for a LED to use in your mothering room, a blue LED is an excellent option to invest in.
Red Lights
Colors under 3000K are considered "warm" colors.  Warm colors such as reds, help to induce flowering in your plants because they mimic the fall sun more closely.  A red LED can help your plant convert into flower production quicker and this can make your plants produce higher yields.
Ultra-Violet / Infrared
If you have the ability to purchase a full spectrum light, you should definitely consider this option.  Ultraviolet and infrared spectrums increase your plant's growth potential by helping to ensure your plants are getting the light they need to increase the energy production from photosynthesis.

Cooling Systems

Your LED light will need some sort of cooling system to help dissipate the heat produced and channel it away from your canopy.  The most common cooling systems found in LEDs incorporate fans and a heatsink to keep your lights a moderate temperature.  The more fans the better.  LED's do not radiate a large amount of heat and the added circulation helps your lights to run more efficiently.

High Temp Circuits

High-temperature circuits can withstand the heat produced by your LEDs better.    Metal core printed circuit boards (MCPCB)are specifically designed to handle prolonged periods of exposure to high heat.  This style of circuit board will add extra years to the life expectancy of your LED.

Heat Sink

When it comes to determining the quality of your LED's heat sink, it is all about the number of fins.  Single finned heat sinks can get hot enough to wear on your circuits and this can result in your LED bulbs burning out prematurely.  By utilizing a multi fin design air can circulate more effectively throughout the heat sink.

Constant Current Drivers

These drivers convert the electricity from your AC (alternating current) outlet to DC (direct current) in order to supply your LED with a constant energy source to sustain power.  This driver needs to be able to regulate the current levels reaching your LED circuits to ensure they do not spike or drop.  If you purchase a LED with a low quality constant current driver, you LED chips are going to burn out much faster.

LED Grow Lights – Advanced Technology

Before the age of LED lighting, most growers were forced to use expensive high output lighting systems.  Not only were these lights far more expensive to operate but they also increased the setup costs of a hydroponics grow significantly due to the fact they not only required the purchase of an expensive light, hood, and ballast, but they also required you to invest into a high-end ventilation system.  This was considered necessary to keep your gardens temperature from becoming too hot for your plants.
Making the switch to LED lighting just makes sense and with all of the new and innovative LED lighting systems to choose from, you are sure to find one that meets your budget and quality standards.  Newer LED lights incorporate space aged full spectrum technology to increase your PARs and give your plants exactly what they need to succeed.  Not all LEDs are created equal and choosing a LED that is low quality can result in you finding yourself with burnt out bulbs and reduced yields.  Avoid this by sticking to one of these proven LED lighting systems below.
