Many lighting experts will say that full-spectrum LED grow lights are the best option for growing plants because they mimic the natural light from the sun. The argument goes:

“Plants have grown under sunlight for millions of years. Why would we want to change what Mother Nature knows is best?”

Well, the team at Lumigrow contends there is no such thing as a full-spectrum LED grow light.

What is a Full-Spectrum LED Grow Light?

In a recent blog post on its Learning Center, experts from Lumigrow argue that a full-spectrum LED grow light is simply a marketing term that implies that your grow light closely resembles light from the sun. This term comes from the concept of “full-spectrum light,” which in recent years has been used to refer to electromagnetic radiation from the ultraviolet to infrared wavebands.

Over time, the term began to take on other characteristics of sunlight. The commercial lighting industry began using the name full-spectrum to sell lights that produced a Color Rendering Index (CRI) over 90. Humans perceive colors more accurately under light sources with a CRI over 90, much like how we see colors in our natural world under daylight. This was a beneficial feature for human environments such as offices, outdoor spaces, and others.

So, what is the problem with the term, and what is the best light spectrum for plant growth? Check out the complete Lumigrow Learning Center post at Lumigrow.com/learning-center/blogs/full-spectrum-led-grow-lights/.
