What is a UVA bulb?

An LED UVA bulb is an LED bulb that will emit a purplish glow to produce UVA light. Since Ultraviolet light has wavelengths shorter than visible light, the beam will be invisible to the naked eye.

Are UV lamps good for your skin?

Ultraviolet light therapy can dry out your skin and cause mild irritation. In addition, long-term UV therapy presents an increased risk of skin cancer. As with any form of treatment, the potential benefits need to be weighed against the potential risks.

What is the main purpose of UVA light?

UV radiation is widely used in industrial processes and in medical and dental practices for a variety of purposes, such as killing bacteria, creating fluorescent effects, curing inks and resins, phototherapy and suntanning.

Is there UV light in a lamp?

It has already been demonstrated that all lamps emit UV radiation, whether they are quartz halogen, tungsten filament incandescent, tube fluorescent or compact fluorescent (mainly the latter). However, the plastic materials used as light diffusers could block the passage of radiation.

What’s the difference between UVA and UVB bulbs?

The difference between UVB and UVA is made by the difference in wavelengths and the energy in the photons of the light. UVA also has a longer wavelength than UVB does. Both of these wavelengths, however, are Ultraviolet, hence the UV.

Are UV lamps safe?

If not used or implemented properly, direct exposure to germicidal ultraviolet lighting can have damaging effects on both materials and people. Over exposure to UV-C lighting can harm humans in a variety of ways, such as eye and skin damage.

Does UVA or UVB cause wrinkles?

UVA rays also play a role in skin cancer formation. In addition, the UVA rays penetrate more deeply into the skin and play a greater role in premature skin aging changes including wrinkle formation (photoaging). There are approximately 500 times more UVA rays in sunlight than UVB rays.

What is the difference between UVA UVB and UVC?

UVA rays have the longest wavelengths, followed by UVB, and UVC rays which have the shortest wavelengths. While UVA and UVB rays are transmitted through the atmosphere, all UVC and some UVB rays are absorbed by the Earth’s ozone layer. So, most of the UV rays you come in contact with are UVA with a small amount of UVB.

How do I know if my light is UV?

A white sock or a piece of paper would suffice. Watch the item. If it turns a violet shade, the UV light bulb is functioning. If it remains primarily white, the UV light bulb might be defective.
