Factors To Consider When Choosing LED growing Lights?

You may be thinking— “Aren’t all grow lights basically the same?” but this is not necessarily true. When you are purchasing grow lights for the first time, or even replacing old ones, you should look for these key features or characteristics when considering one light over another. These points will help you conclude which is right for your specific case.

Full Spectrum

This is the first feature you should consider. Plants are not only need red and blue spectrums, but also infrared and ultraviolet rays. So, the full spectrum LED grow lights will give higher yield than the others

Shape of the Light

LED grow lights are available in a variety of shapes from panels to saucer shape and even light bars. It is best to consider where you will be setting up your indoor growing space and this will assist in deciding which shape is suitable for you. Smaller lights are great for smaller space but also for setting up in scattered patterns, whereas a panel light covers longer stretches of space.

Hours of Burn Time

Not all LED lights burn at the same rate. You should always check to see what the estimated life expectancy of each light is prior to purchasing. A higher dollar amount does not necessarily mean you are getting the best value or the best LED grow lights high times. Read the packaging to see how long you should expect to have this light before it needs replacing.

Excellent Quality Internal Chip

At the heart of every LED light is a chip which will convert your electricity into light. This chip must be of high quality to ensure there is enough powerful light to get your garden growing. A good rule of thumb is to find an LED light with a chip of at least 3 watts, so you can be sure it has enough luminosity to get the job done.

Lower Heat Generation

This is an important key feature for any LED growing lights you purchase. Some LED lights will output higher heat and create a warmer environment in doing so. In turn, you would have to cool your space with fans to have the proper growing temperature for your plants. To save yourself having this set up, it is much simpler to purchase LED lights with a low heat output. Not only will they generate less atmospheric heat, they tend to last longer since they are not burning so hot at a constant rate.

Ease of Use

Even if you are not new to indoor gardening, your time is important. The last thing you want to be doing is tinkering with your LED grow lights for hours trying to get them adjusted just right. Choose an LED light which is simple and easy to use. This means you should be able to easily set the height and intensity without much fuss.

Size of Your Expected Garden

Before purchasing any best lights for indoor growing, you must know exactly how big your indoor growing space will be. This will help you decide how many lights you will require and could sway the shape and size of LED light you choose. A great guide to how many lights you will require is:

Plants requiring higher amounts of light: around 32 watts per square foot

Plants requiring lower amounts of light: around 14 watts per square foot

Type of Grow Light


LED (Light-emitting Diode)

LED lights offer the full spectrum required for indoor plant cultivation. Compared to other grow lights, they are the most efficient in energy consumption, producing the lowest level of heat. Furthermore, LEDs have a longer lifespan compared to other grow lights. However, the light produced by LEDs is not good for your eyes.

HID (High-Intensity Discharge)

This grow light consumes way more energy than LEDs. The lifespan is considerably shorter compared to LEDs, and they produce a high level of heat. To prevent heat damage to your cannabis plants, they should be installed at a distance from the plants. There are many high-intensity discharge lights to choose from.


Fluorescent grow lights are really affordable, and they have a reasonably long lifespan. However, they will not last as long as LEDs, and they are not the best grow lights to use during the flowering stages. Like HIDs, there are so several types of fluorescent grow lights to choose from on the market.
