The Impact Of LED Grow Lights On Human Health

The rapid gain in the use of LED technology for horticultural lighting software has also raised discussions concerning the possible human health risks in comparison with legacy lighting solutions. This is due to the differences in visual appearance (color and intensities) of the lighting within such applications.

In a high enough intensity, any type of light, regardless of the origin has the potential to harm the skin or eyes via prolonged thermal exposure or photochemical effects of ultraviolet, blue light &/or infrared emissions. Shorter wavelength, high energy blue light (400nm and 500nm) can lead to retina damage through a combination of photochemical action and high intensity. Greater concentration light sources will provide more direct energy and a higher risk. By way of example, staring in a clear blue sky (scattered blue light) is a low hazard, while looking straight at sunlight can begin irreversible harm almost immediately.

Prolonged direct screening of bright light sources must always be avoided, particularly at short distances. In practice, nobody willingly spends any substantial time looking at an extreme light source. Common sense and the natural human instinctive aversion response (we instinctively closed our eyes or look away) means that prolonged direct exposure of the eye to a potentially damaging light source will be avoided.

As with other lighting technology, LED grow lights must be assessed for photobiological safety according to EN 62471 — the benchmark for photobiological safety of lamps and lamp systems. EN 62471 exposure limit classifications represent conditions under which it’s believed most people may be repeatedly exposed without adverse health consequences. It should be noted that the classification just suggests potential risk. Depending upon use, the threat may not actually become a real hazard.

When it comes to human visual perception, what is often forgotten is that “traditional” light sources were never designed or intended particularly for horticulture applications. Historically, artificial light has always been optimized for human visual benefit. Patriot LED grow lights are authentic wide spectrum lights, meaning that they contain bits of colors from the spectrum, including away from the PAR region, just like the sun. Because of this, they appear from white to soft pink that makes them nice to work under and makes identifying the color of plants beneath these simple. A cheap alternative to this, which many LED manufacturers opt for, is using red, blue and white LED chips which result in a strong, piercing pink color, disagreeable to human eyes. Concerning health consequences, Best LED grow lights are not blue dominant and therefore are categorized in the no-risk or lowest risk group.

The eye is a intricate organ that obviously strives its best to compensate for varying lighting conditions, and LED grow light spectra might not always appear “organic” to people. If lighting conditions to the human eye change (e.g. moving out of a LED lit growth environment to natural daylight), color perception might be temporarily affected while the eye adjusts. This is natural and should not be misinterpreted as potential “harm” from exposure to LED light.

In conclusion, it can be stated that commercially available LED lighting sources (for horticultural or other programs) could be considered human safe when designed, installed and utilized in compliance with the applicable standards, regulations and manufacturer’s instructions. Overall, regarding photobiological security, Best LED grow lights have similar characteristics to those of some other light technology.
