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.

This is the among the best selling LED Grow Light online, and also gets stellar ratings. This is not only because it is budget-friendly, but it does satisfy most small to medium growers' needs. The Roleadro has a 300W, 600W rated LED panel. 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 2x2 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.

- Wide spectrum light
- Ideal for small grows and beginners
- Large fans and heat sink
- Superior output for flowering plants
- No switch for power control.

Deckey Full Spectrum Hanging LED Grow Light
Grow Light Specs
- Very inexpensive
- Suitable for beginners
- Power: 9W
- 60 blue and 165 red light
- Material: plastic
- 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 12.2x12.2 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.

- Consumes only 9 watts
- Complete package for easy installation
- Underpowered for large plants
- Not ideal for flowering stage
- No advanced options
UNIFUN LED Grow Light
Grow Light Specs
- 4 color spectrum
- IR and UV included
- 1-year warranty. 30-day product return guarantee
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.
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
- Some bulbs fail with regular use
- No dimming option
