The bottom line is that LED grow lights are no more dangerous than any other type of grow light. HPS is much more dangerous than LEDs – high heat and risk of burns, risk of broken bulbs and fires, high environmental damage due to mercury content, high carbon footprint.
Are LED grow lights bad for your skin?
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 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 LED room lights bad for your eyes?
The “blue light” in LED lighting can damage the eye’s retina and disturb natural sleep rhythms, France’s government-run health watchdog said this week. LED uses only a fifth of the electricity needed for an incandescent bulb of comparable brightness. …
Can you leave grow lights on 24 hours a day?
A: In general, you should not leave grow lights on 24/7. Plants need a light-dark cycle to develop properly. It’s believed that they truly do “rest” during periods of darkness, and probably use this time to move nutrients into their extremities while taking a break from growing.
Can LED grow lights cause cancer?
The Potential Danger of UV Light For Humans
But it isn’t only about skin care. … Likewise, most LED grow light manufacturers keep UVC out of their supplemental UV lights. 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.
Is LED light dangerous?
The AMA says that life-long exposure of the retina and lens to blue peaks from LEDs can increase the risk of cataract and age-related macular degeneration. Studies also reveal that light emitted by LEDs can cause retinal changes, if there is high exposure for even a short period of time.
Can LED lights kill bacteria?
LED light is killing bacteria, fungus and mold, and the scientific community has validated the results. … Intensities of 400 to 420 nanometers (nm) did the trick, 405 being the sweet spot for bacteria deactivation. In 2012, LED work continued with blue light disinfecting other bacteria including listeria and E. coli.
What are the best grow lights for indoor plants?
High Intensity Discharge solutions like Metal Halide (MH) and High Pressure Sodium (HPS) lights are good choices, though expensive to purchase and operate. Extremely efficient, high energy discharge throw a lot of light and the blue light of MH lights will promote vegetative growth, but produce less flowering.
Which LED light is best for eyes?
Warm light is best for the eyes. This includes filtered natural light and light produced by incandescent and LED light bulbs.
Are LED lights safe for bedroom?
By paying attention to the LED bulb specifications, and taking appropriate precautions and using some basic common sense, you can safely incorporate LED lights in your home without any negative health effects of the “blue light hazard.”
Is daylight or soft white better?
Soft white (2,700 to 3,000 Kelvin) is warm and yellow, the typical color range you get from incandescent bulbs. … Daylight (5,000 to 6,500 Kelvin) has a more bluish tone. This light color will maximize contrast for colors, making it ideal for working, reading or applying makeup.
Can you leave grow lights on 24 hours a day for tomatoes?
Scientists have found a gene in wild tomatoes that enables farmed tomato plants to be grown 24 hours a day under natural and artificial light, boosting yields by up to 20 per cent. … As a result, commercial tomatoes have to be grown under a day-night cycle in which light is limited to around 16 hours a day.
How many hours a day should grow lights be on?
Plants grown indoors require more hours of light than those grown outdoors. 14 to 18 hours of light per day is recommended for most edible species when grown under artificial lighting. Don’t be tempted to leave the lights on 24-7, however – at least six hours of darkness each day is essential to plant health.
Can plants get too much LED light?
The reality is that modern LED grow lights can produce a very high level of light and it can cause photo-bleaching and burn leaves. This depends very much on the plant, but a PPFD of 800 is enough to damage some plants.
