When growing plants 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:
1. 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.
2. 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,
3. 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.
What exactly is full spectrum LED grow light and why is it important?
First, you must understand the light spectrum, or color wavelengths. It is the range of light colors we see or didn’t see. Visible light that our eyes can see is between 380-740 nanometers. And similarly, the leaves of plants also enjoy these visible wavelength; the chlorophyll uses these light to manufacture food. The green light is an exception. Because chlorophyll only reflects green and they don’t absorb it, that explains why plants’ leaves are green. You can read more about these in this article.
So for the most parts, plants respond to the blue and red colors very well. These are the two most important wavelengths that plants need during their growth. Basically, plants need blue light for their vegetative phase and red light for the flowering period.
Understanding that, many grow light manufacturers have made it possible to produce the light colors plants need with their LEDs light. Many modern LED grow lights have a programmable setting to produce different color wavelengths. By this, you can control the type of lights at the different ratios for plants at different stages of growth in their life.
These types of LED lights with a very wide or full range of color wavelengths are called full-spectrum LED grow lights.
So two of the most important criteria that affect plant growth are light intensity (or the power of light output), and light colors (color wavelengths).
For light intensity, you can opt for the powerful light, but for light colors, you should choose one with a wide range of color wavelength (or full spectrum).
That’s why within the scope of this article, I’ll go into details all full-spectrum LED grow lights on the market, and help you pick the right one.

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
LED Grow Lights Buying Guide
What are LED Grow lights?
LED technology is not something groundbreaking. It has been around for decades now.
LED stands for “light emitting diode.” It is a small bulb that converts electricity into light energy. The history of LED lights stretches back all the way back to 1907.
The earliest LED bulbs in the 1960s and ‘70s were costly and used only in advanced instruments.
But in recent years, the costs have declined, and LEDs are used in everything from home lighting to consumer devices like TVs and mobile devices.
It was only a matter of time before LED panels started appearing in the hydroponics and indoor grow scene as well.
These days, LED grow lights are available in different sizes, intensities, and colors to suit various plant requirements. They are accessible for both small-scale as well as commercial productions.
What are the advantages of LED grow lights over HIDs?
Compared to incandescent lamps, LED bulbs and panels emit much less heat. This is very important for plants, as extra heat can damage your crop.
Less heat also means that you can keep the lights much closer to the plants without fear of damage to the crop. That is one less factor to worry about when planning your grow system.
Less Power Consumption
Older incandescent lights are inefficient because a lot of the energy supplied is lost in the form of heat.
But since LEDs emit less heat, less electricity is being wasted as well. If you supply the same amount of electricity to an LED and HID, the LED will provide more light.
Typically, you can expect energy savings to the tune of 25-50% from LEDs.
Compact & Space Saving
In indoor grow areas, space is a precious commodity. LED systems take much less room than HIDs, and are easier to move around and manage.
Again, since they emit less heat, they also don’t need extra cooling equipment, unlike older HID lamps. This means less clutter.
LED grow systems these days are very flexible and can often be chained together. So you might even be able to reduce the mess of extra wiring.
Better Light Optimization
Plants require different light wavelengths during various stages in their light cycle.
These days, LED lights are available in different wavelengths. Many LED grow light systems also come with the option of adjustable wavelengths (Full spectrum LED lights).
By using specific wavelengths for plants at the correct stages, you can get maximum growth with minimal wastage of input energy.
We all know about the fragility of incandescent bulbs. They have a propensity to burn out sooner or later.
LEDs are a different breed altogether. As they produce less heat, the components have less chance of burning up.
Modern LEDs often have a rated lifespan of tens of thousands of hours. So despite their higher cost, they are a more economical proposition in the long term.
