Once you know the basic grow light metrics, you’ll feel more comfortable choosing the best lights for your vegetable garden, or small grow lights for houseplants; the opportunities for indoor gardening are endless.
What Makes the Best LED Grow Lights?
The best LED grow lights have several things in common — uniform light spectrum, efficiency, high power and reliability/durability.
Spectrum/Uniformity
The best LED grow lights have a uniform spectrum, so if you have 4 plants under your light, they will all get the same spectrum.
We’ve touched on the spectrum a bit, but it’s important to reiterate that the best spectra include not only red and blue light, but also infrared (IR) and ultraviolet (UV).
Full-spectrum LEDs allow you to use the same light from seed to harvest instead of having to change bulbs or use different grow lights to grow vegetables/flowers.
Strength
The more light the LEDs actually emit, the more yield you’ll get (in most cases). Therefore, the best LED grow lights need to be very powerful.
Efficiency
Generally speaking, LED grow lights are very efficient. However, the best LED grow lights are also often the most efficient. It is very important to operate at a high level, generate high power, and keep it low cost.
Reliability/Durability
Given the cost of LED grow lights, they need to be considered an investment. Obviously, your investment needs to last a long time to show returns.
Therefore, the best LED grow lights are reliable and durable to stand the test of time.
All the lights we will list are from the most reputable brands and include some kind of warranty. This will give you peace of mind when purchasing knowing you are protected.

What To Look For in a Good Grow Light
Before selecting a particular grow light, you must carefully examine the following characteristics:
Power
It is crucial that your grow light is energy-efficient so that you can avoid paying high electricity bills. Grow lights with a lower output wattage are cheaper to operate and don’t generate a lot of heat that could burn your plant. Keep in mind that the higher the wattage is, the hotter the grow light will get, and the more energy it will consume.
Full-spectrum
To support the growth of plants in an indoor environment it is essential to ensure that the grow light you get is capable of outputting a full spectrum of light, as this will mimic the natural light of the sun. With that said, full-spectrum LEDs are more expensive, but they do provide a full spectrum of light for optimal growth in all stages of a plant’s life.
Temperature
The temperature of your grow light is crucial, as it will directly affect your indoor plants. You will want to choose a grow light that doesn’t emit more heat than natural light. We suggest white or yellow lights for smaller plant installations in your home. Red lights may be more optimal for growing fruits in the home, as these provide the heat needed to promote the growth of more sturdy plants.
Conclusion
LED grow lights have become very popular as an effective way to provide light to plants to help them grow. These lamps provide specific light and heat to the plants, promoting their growth. The best LED grow lights can be expensive and take some getting used to. But the people who invest in them, swear by them.
