Yes, most grow lights do come with UVB and UVA. UVB is an ultraviolet light that is beneficial for plants because it triggers natural defense systems in the plant, promoting vitamin D3 production, and increasing plant cell growth which allows for a more robust and healthy plant.
Meanwhile, UVA is an ultraviolet light that helps with photosynthesis and helps improve the overall health of the plant. In particular, UVA is used to trick the plant into thinking that it is in long days and short nights, which in turn encourages flowering.
By having both UVB and UVA, the grow lights can provide a complete spectrum of light for the plant, making for a more complete and healthy experience for the plant.

Do plants need UVA or UVB to grow?
Yes, plants need UVA and UVB light to grow. UVA and UVB light are essential for the process of photosynthesis, which plants use to convert light energy into chemical energy that their cells can use to produce sugar, carbohydrates, and other growth materials.
UVB light from the sun allows plants’ leaves to produce Vitamin D, which is essential for their growth and survival. UVA helps increase chlorophyll and carotenoids production in plant cells, resulting in increased seed germination, root growth, and flowering.
Without either UVA or UVB, plants won’t be able to produce the necessary energy to survive and grow.
Does full spectrum grow light include UV?
Yes, full spectrum grow lights usually include ultraviolet (UV) light. UV light is an important part of the light spectrum for growing plants and comes in two types: UVA and UVB. UVA is important for promoting general health and vigor while UVB helps promote the production of Vitamin D3 which aids in the proper uptake of nutrients.
While some lamps may not include any UV light, most do, as it is an important component for healthy plant growth.
Can grow lights completely replace sunlight?
No, grow lights cannot completely replace sunlight. Sunlight provides a range of natural light spectra and also has a naturally balanced combination of different light wavelengths, including UV and infrared.
Grow lights generally provide only specific wavelengths or spectral bands of light, missing out on all others. The sun also helps regulate plants’ day and night cycles via the entraining of circadian rhythms with light and dark.
Without natural sunlight, plants may not be able to obtain enough energy for key growth and reproductive activities. Grow lights can be a great supplement to natural sunlight, but cannot completely replace it.
Do LED lights produce UV light?
No, LED lights do not produce ultraviolet (UV) light. LEDs are typically designed to produce light in the visible spectrum, which is a type of electromagnetic radiation that humans can see. UV light is a type of electromagnetic radiation that is outside the visible spectrum, which means that humans cannot see it.
Some LED lights can be filtered to emit some UV radiation, but it is not the same as natural UV light and may not provide the same benefits.
Can you get sunburn from LED grow lights?
No, you cannot get sunburn from LED grow lights. This is because LED grow lights do not produce the same type of ultraviolet radiation as the sun and therefore cannot cause sunburn. However, although the risk of burning is generally low, it is still possible to get eye strain, headaches, or skin irritation from the intense light emitted by the LEDs.
It is important to use caution and make sure you are keeping at a safe distance when using LED grow lights. Additionally, in order to prevent eye strain, headaches, or other types of discomfort, you should also wear protective eyewear such as safety glasses or goggles to avoid the intense bright light from your LED grow lights.
How much UV do LED lights emit?
LED lights emit very little UV radiation, as compared to other types of lighting. The amount of UV radiation emitted from a typical LED light is usually negligible, with most of the emitted light being in the visible light spectrum.
The amount of UV emitted from an LED light will vary depending on the model and manufacturer, but typically it is less than 10%, and sometimes even less than 1%. This means that LED lights often require no special UV protective measures, unlike other types of lighting.
Additionally, some manufacturers have developed special LED technology that actively reduces any UV radiation that is emitted, making it even safer for you, your family and your environment.
Do grow lights give off radiation?
Yes, grow lights give off radiation. Different types of grow lights emit different types of radiation. For example, fluorescent bulbs emit ultraviolet (UV) radiation. High-pressure sodium (HPS) and metal halide (MH) grow lights emit visible light along with infrared radiation, while LED grow lights emit mainly visible light in the red and blue spectrum.
All of these types of radiation can have an impact on the growth and development of plants, so it is important to choose the right type of grow light for your needs. Also, it is important to make sure that you are using the grow light in the proper distance from the plants, as too much radiation can be damaging.
Does LED light tan your skin?
No, LED light does not tan your skin. LED lights are a type of lighting that is composed of several tiny light-emitting diodes (LEDs), which are electrical devices that convert electrical energy into light.
They emit light in very specific wavelengths and are used in a variety of devices. While LED light can be used therapeutically to treat skin conditions, such as acne or inflammation, it does not tan the skin.
This is because the wavelengths of the light emitted from it do not contain the ultraviolet rays that cause tanning of the skin. Therefore, it is not effective in producing the cosmetic tanning effect.
What light does not emit UV?
Many types of light do not emit UV, including fluorescent, incandescent and LED lights. Fluorescent lights are made of a type of glass that blocks UV radiation, while incandescent and LED bulbs use a material that is reflective of UV radiation.
Additionally, natural light sources such as firelight and moonlight do not emit UV either. Sunlight is the primary source of UV radiation, and these other light sources are unlikely to contain significant amounts of UV radiation.
Is LED safer than UV?
Yes, LED is generally safer than UV, primarily due to the fact that LED light emits less energy. UV lighting typically requires more energy and therefore is more likely to create harmful rays that can cause skin damage, burns, and injury to eyes.
LED light treatments use less energy, which makes them duller to the eye and less likely to create harmful rays. When used properly, LED therapies can provide great aesthetic benefits without many of the harmful side effects that are more commonly seen with UV treatments.
Additionally, LED lights don’t operate as hot as UV lamps, so the risk of burning is significantly lower. Therefore, LED is safer than UV in terms of both medical risks and the potential for skin irritation or damage.
Is LED a carcinogen?
No, Light Emitting Diode (LED) is generally not considered a carcinogen. LEDs do not emit UV radiation, and the electromagnetic radiation they emit is generally considered to be non-ionizing, meaning that it does not directly damage cells.
A review of the available scientific research does not suggest any evidence that LED bulbs are linked to cancer risk. Some researchers have suggested that there is a potential for LED to cause subtle alterations in human health, but this remains to be seen in further studies.
LEDs are also not considered to be a source of air pollution or heavy metal pollution. In summary, LED lights are considered to be safe and non-carcinogenic.
Are grow lights considered UV light?
No, grow lights are not considered UV light. Grow lights are specially designed to emit a type of light that is ideal for growing plants, and generally emit very little or no UV radiation. The blue and red wavelengths of light used in many grow lights are the ideal ones for plant growth, but those lights do not typically include UV radiation.
Even some fluorescent grow lights emit little to no UV radiation. On the other hand, some sources of artificial lighting, such as many halogen and metal halides, may emit UV light in higher amounts. However, these types of light are not typically used as grow lights, as the UV radiation they produce falls outside of the ideal wavelengths of light for promoting plant growth.
Is full spectrum UV?
No, full spectrum is not UV. Full spectrum simply means the whole spectrum of visible light from infrared to ultraviolet. Visible light includes both infrared and ultraviolet but UV is only a small part of the visible spectrum.
Full spectrum does not have the same meaning as UV and does not refer exclusively to the ultraviolet spectrum.
Can you get vitamin D from full spectrum light?
Yes, you can get vitamin D from full spectrum light. The sun is the main source of vitamin D, and when exposed to direct sunlight, the body’s natural process can produce vitamin D. Full spectrum light is believed to be a comparable source of vitamin D to sunshine.
It is important to note that the amount of vitamin D you can get from full spectrum light depends on the strength and intensity of the light. Based on research, lamps and bulbs that specialize in full-spectrum lighting have the capacity to provide an adequate amount of vitamin D.
In order to get the most effective amount of vitamin D from full spectrum light, it should be bright enough to produce 10-15 foot candles at one’s level of standing or seated position.
