The Best Led Grow Lights 2018

*Updated: Best LED Grow Lights for Cannabis

What are the best LED grow lights for 2018? Overview and learn almost everything you need to know about LED Grow Lights and how to choose the best led grow light for your grow room.

When growing marijuana indoors, replicating the effect of sunlight is often the biggest hurdle. Sodium, fluorescent, and HID lamps emit too much heat, and are very power hungry.

Modern LEDs are superior in these two aspects. Check out our review list and the buying guide to learn how the best LED grow lights can improve your hydroponics/aquaponics system.

What are the factors to consider while shopping for LED grow lights?

There are three major factors you have to consider before picking an LED system for your indoor grow operation:

What are you growing?

Depending on their species and variety, plants have varying light requirements. Generally, full-spectrum light is essential for photosynthesis.

But even for this purpose, blue and red lights seem to be most important.

And plants from dry, sunny areas like the Mediterranean will need more intense light than those originating from sub-tropical or temperate regions.

Low-light plants like lettuce and herbs will need 25 watts per square feet, while high light plants like tomatoes will need at least 50 watts.

These are just ball-park figures. Different varieties will have their unique requirements.

How large is your indoor grow project?

This pretty much self-explanatory. The larger your grow area, the more LED bulbs or panels you will require.

There are a lot of options to choose from. Depending on the shape and size of your grow area, you can pick from LED tubes, panels, bars, bulbs,

What type of LEDs do you need?

There are two options: full spectrum lights, and separate vegging and blooming lights.

Full spectrum lights are all-around products that can provide adequate lighting for a plant throughout its life cycles.

But in some situations, you might be opting for a more focused approach. For example, your system may be having separate growing areas for the growing period and flowering periods.

In such conditions, you can opt for a vegging LED light for the growth stage, and blooming LEDs for the flowering stage.

Many good quality full spectrum lights these days come with programmable settings. With these, you can opt for veg or blooming light settings depending on the age of your plant.

What are some good features to look for in LED grow lights?

  • If buying full spectrum LEDs, get one with adjustable output spectrum settings.
  • If you are opting for high powered LEDs, always make sure that they have proper cooling systems (heat sink & fans on the circuit board).
  • Again for higher power systems, ensure that the circuit board is MCPCB (metal core printed circuit board).
  • Look for LED fixtures that have a constant current driver circuit to ensure proper supply of direct current at all times.

A very useful feature in this system is the ability to daisy-chain multiple panels together without using many power outlets.

As a higher watt panel, the VIPARSPECTRA LED has a cooling system with fans and an aluminum heat sink built into it.

The panel provides enough coverage over a 2×2 feet area (300W model), 3.5×3.5′ (450W model), 4×4′(600W model), 5×5′(1200W model)

The LED panels perform as expected, according to overwhelming user feedback online. They generate very little heat, and provide adequate and balanced light, for both veg and bloom stage.

  • Full spectrum; has IR, red, and blue LEDs
  • Reflector saves extra light from escaping

The California Light Works SolarSystem 550 is the top of the line LED grow light. What separates it from the competition is the fact that it has a programmable spectrum as well as the quality of the LEDs used in their led grow light systems. The higher quality LEDs produce a higher yield as well as touch some of the ideal spectrums for more potent harvests.

The Led Lights from California Lightworks are no doubt a high-end model that will deliver the quality lights that get plants to work well at all stages.

The SolarStorm is one of the two series of California Lightwork besides the SolarSystem. It is aimed at small and normal growers. This model owns a separate switch mode for veg/bloom. And another switch for the UV-B bulbs

The SolarSystem has more power and comes with programmable spectrum control, which is better suited for large and commercial production.

They have 5 bands of deep blue, blue, red, deep red, warm white, plus UV-B emitted by attached UVB T8 fluorescent bulbs. But they lack IR.

And recently, the manufacturer released the 2nd generation of this model with higher Epiled chips (5W), improved spectrum range, upgraded cooling heat sinks, and cooling fans as the company states

The panel has a rectangular shape and contains full spectrum LEDs. There are individual Epileds LED chips inside, each rated at 3W or 5W (depending on the model).

With the 300W 1st gen model, out of the 100, 86 are red LEDs, with 10 for blue light, and two for IR and UV lights. At a standard 24 inch height, this panel can illuminate a growing area of 2×2 feet.

Heat management is handled by two large fans and a large heatsink attached to the circuit board. The panel is sold with a long power cord and hangers.

The 300W panel provides adequate lighting for smaller grows. These seem to offer excellent light for both vegetative as well as flowering stages.

I would recommend the Roleadro 1st gen for its stability, and because I prefer 3W chips, which help improve light penetration for lower parts of plants.

  • Power: 9W
  • 60 blue and 165 red light

  • No display of warranty and product return policy

The list would not be complete without some sub-50W variants.

The Deckey grow light is a dual spectrum panel made up of 225 individual LEDs.

Of these 165 are red colored, while the rest (60) emit blue color light. They combine to provide the optimum level of light for plants at all stages.

The panel is square shaped, measuring 12.2×12.2 inches. As the name suggests, the LED is designed to be hung from the ceiling. This Deckey LED is rated at under 10 watts.

It can be kept at a distance between 1.6 feet to 3.2 feet. At the maximum distance, it should be able to cover 2.5 square meters or 26 square feet.

The light is fabricated from high-quality plastics. You get a rather long 1.65-meter cable along with the light. Other mounting accessories are also provided along with the package.

As for the actual performance, the Deckey is a very low powered grow light. It is not suitable for large flowering plants.

Despite being stated by the seller as a full spectrum panel, it only displays blue and red colors and is not enough for all stages of plant growth. The Deckey is only perfect for the vegging or early growing phase though.

  • Has both blue and red LEDs
  • Consumes only 9 watts
  • Complete package for easy installation
  • Underpowered for large plants
  • Not ideal for flowering stage
  • No advanced options

The UNIFUN system is more powerful than the Dewey, with a wattage of 45 watts for the panel. And like the Dewey, this one is also a full spectrum system.

The number of red LEDs stands at around 160, with about 55-56 blue LEDs. The added attraction is the presence of 8 special LEDs for UV and IR spectrum rays.

The square panel measures roughly 12 square inches in size. The maximum wattage is 45, and the light can irradiate a maximum area of 1.5 square meters.

The system has a straightforward plug and play system. As long as an outlet is close at hand, you don’t have to worry about complicated wiring systems.

The main advantage of the UNIFUN LED is that it can be used to grow a wide a variety of plants. They include both low light and high light varieties.

Best Grow Tents

But the 45-watt peak rating is too weak for the blooming or flowering stage of the plants. In the early seedling stage, this is a perfectly viable option according to expert feedback.

The light system generates very little heat. It is also very easy to install as it comes with a dedicated hanger kit.

  • Ideal for beginners and first timers
  • Suitable for small grows
  • Has both red and blue light, as well as UV and IR
  • Very easy to install
  • Too weak for the fruit and flower blooming stage
  • The construction is very flimsy
