Yes, UV has benefits for plant growth, but it can still cause damage to plants and humans if not used properly. ... Exposing plants to that much UV can quickly kill them. Growers should provide their plants with a full quality spectrum which emits the right amount of UV.

Ultraviolet light B (UVB) Ultraviolet B, which is present in natural sunlight, is an effective treatment for psoriasis. UVB penetrates the skin and slows the growth of affected skin cells.

Sun lamps can be a convenient way to achieve a sun tan when weather conditions do not permit natural sunlight exposure or the user wants a quick and easy alternative for achieving a sun tan. ... Through the use of UVA or UVB rays, sun lamps provide a relatively quick and easy tanning option.

UV light produces oxidative stress of the skin due to excessive production of reactive oxygen species (ROS), which can damage cells, causing cell aging or cancer. Antioxidants neutralize these harmful agents, but their activity decreases with organism age and metabolic state.

House plants adapt perfectly well to growing under artificial light. Incandescent lamps, however, even those offered for plants, produce light of poor quality that promotes weak, unhealthy growth. They are only good choices for house plants receiving some natural light.

Two types of UV light are proven to contribute to the risk for skin cancer: Ultraviolet A (UVA) has a longer wavelength, and is associated with skin aging. Ultraviolet B (UVB) has a shorter wavelength and is associated with skin burning.

Strong sources of long-wave ultraviolet light are used in tanning beds. Although the low-power UV-A emitted by black lights is not a hazard to skin or eyes and can be viewed without protection, powerful ultraviolet sources present dangers and require personal protective equipment such as goggles and gloves.

Luckily, “warm light” CFLs (Compact Fluorescent Lights) are okay for your eyes, as well as being much more efficient. They do emit UV rays, but a much smaller amount. You can also use LED bulbs or halogens.

Most grow lights provide full-spectrum light. Most of the light plants use is from the blue ("cool") and red ("warm") ends of the spectrum; they use little yellow and green light.

If UV lamps are used in hospitals and kitchens, they're certainly safe enough to use in the home. UV lamps, even though they use ultraviolet light, don't directly affect you. The lamp only affects whatever is directly in its line of sight. However, it is worth noting that UV lamps can impact the actual HVAC system.

Phototherapy is different, however. It employs very specific wavelengths of UV light. Furthermore, these wavelengths are different from the ones used in tanning beds. ... In contrast, tanning beds use bulbs that typically emit 95% UVA (320-400 nm) and 5% UVB (290-320 nm) light.

Tanning equipment is NOT safer than natural sun exposure. Tanning equipment usually emits higher levels of UV radiation than the UV radiation outside. Compared to the sun, sunlamps and tanning beds can emit up to 10 times more UVB radiation and on average 2 to 14 times more UVA radiation than the sun.

The only requirement is sunshine–specifically ultraviolet B rays," according to Mayo Clinic website. And just as people need vitamin D to thrive, so do plants. It makes sense, therefore, that full-spectrum light bulbs–those used in light therapy to treat Season Affective Disorder–could be used to help plants grow.

UV rays from sunbeds Sunbeds, sunlamps and tanning booths give out the same type of harmful radiation as sunlight. UVA rays make up about 95% of sunlight. ... Using a sunbed to get a tan is not safer than tanning in the sun.

In addition to heat, dart frogs need some UVB lighting to help absorb calcium and to synthesize vitamin D3. In the wild, a lot of the UVB lighting is filtered by the tree canopy, so you'll want to use a 13 watt UVB Exo Terra 100 on top of a screen to filter some of the rays.

While Ball Pythons don't need UVB to survive, UVA/UVB light has been shown to greatly improve the immune system, health, and wellness of all reptiles, both diurnal and crepuscular. Make sure to place the light over the side with the heat mat to help create that warm side of the thermal gradient.

Plants have a rhythm, often regulated by the light. If your solar lights are soft and only used for mood lighting, it should not hurt the plants. However, if they are brighter or concentrated on a certain part of your lawn, it could disrupt the plant's rhythm.
