Whether or not a grow light is dangerous is completely based on how someone is working around it. There’s a mountain of scientific evidence that demonstrates the danger of UV, visible and infrared (IR) radiation. Extreme amounts of all three can be produced by modern grow lights. But understand this: Grow lights are amazing tools that are vital to our industry and community. But like any tool, it’s the responsibility of the user to operate it safely and protect themselves. If you bang your thumb while hammering a nail, who do you blame for the injury? Grow lights are designed specifically to maximize plant responses in a minimal amount of time, and they are amazing at that job. It is up to all of us to properly educate and protect ourselves accordingly.
