Are grow lights harmful to humans?
At a high enough intensity, any type of light, regardless of the source has the potential to harm the eyes or skin through prolonged thermal exposure or photochemical effects of ultraviolet, blue light &/or infrared emissions.
Can LED grow lights catch fire?
Are LED Grow Lights A Fire Hazard? LED grow lights are probably the safest forms of grow lights to use because of the low heat output of these lights. The heat that they produce is not sufficient on their own to cause a fire.
Is it safe to leave LED grow lights on?
LEDs are probably the safest option for grow lights (if one of the more expensive options) because they put out a small amount of heat, at least relative to traditional halide and high-pressure sodium lights, and they also consume less power, which saves on electricity costs.
Do grow lights give off radiation?
What Types of Rays are Harmful? Artificial lights, specifically those designed for indoor horticulture, can produce harmful levels of UV, Visible and Infrared (IR) radiation. … Also common to the growing industry is Visible light, or blue light, which has been shown to cause irreversible cell damage in the skin.
Can grow lights make you sick?
Arnold Wilkins—one of the leading researchers on lighting and health—has stated that LED bulbs switch on and off hundreds of times per second. This can lead to symptoms of eye movement dysfunction, double vision, headache, dizziness and the feeling of being unwell, all within 20 minutes of exposure!
Are grow lights cancerous?
However, most UV lights will contain UVA and UVB. As you probably know, UV rays can cause skin cancer with prolonged exposure and no protection. … Exposure to UVA light has been linked to retinal damage such as cataracts. However, UVB can actually be filtered by the cornea.
Can grow lights give you vitamin D?
Sunlight spurs the production of one form of vitamin D, an essential nutrient. An alternative to getting out in the sun is to use a grow light, but only one type of grow light stimulates vitamin D production.
Are purple grow lights better than white?
White LEDs emit some far red, and so plants may be slightly taller, and some plants may flower slightly earlier, than under red+blue LEDs. … LED fixtures that emit a purplish light are usually less preferred by people, but are often the most efficient at converting electricity into light useful to plants.
