THE DIFFERENCE BETWEEN UV LIGHT AND BLACK LIGHT

THE DIFFERENCE BETWEEN UV LIGHT AND BLACK LIGHT

The debate between black light and UV light is one that frequently leads to misunderstandings among customers who are looking for an appropriate answer to meet their requirements in terms of filtering and disinfecting their environment. When we think of black light, our thoughts frequently go to the rear of limousines or to dark nightclubs; we should also give an honourable mention to just about any forensic-themed crime show that is broadcast on television. However, what exactly is black light, and how is it different from ultraviolet (UV) light? Whether you're looking for a more cost-effective way to sterilise water or intending to dust for fingerprints, the moment has come to put an end to the ongoing argument between black light and UV light once and for all.

What's the Difference Between Black Light and UV Light, Anyway?

Both black light and ultraviolet light are known to emit a hue that can be described as purple or violet. However, the reason for this is more likely due to the fact that our capacity to sense colour is determined by the very narrow human visual spectrum. Both of these types of light are located just slightly outside of that spectrum, and the last colour that humans are able to differentiate in this environment is violet because our eyes have red receptors. Therefore, what is the key distinction between the two?

Light in the Dark

To put it more plainly, black light is a kind of ultraviolet light; more specifically, it is a form of ultraviolet A (UVA) light, which means that it produces ultraviolet radiation in the UVA band. In terms of the dangers posed by ultraviolet radiation, these rays provide the least risk because they have a low energy level and a long wave length. Black light is not among the forms of light that are known to cause sunburns or even skin cancer; however, staring at a black light for an extended period of time is not recommended. The types of light known to cause sunburns and even skin cancer include UVB and UVC light. Although black light lacks the potency of ultraviolet (UV) light in applications requiring sterilisation and filtration, it can make white garments appear to have a more interesting appearance in the dark.

Ultraviolet Light

On the other hand, ultraviolet (UV) light is composed of ultraviolet (UV) A light and ultraviolet (UV) B light, but not ultraviolet (UV) C light. UVC light would technically be the most destructive and hazardous of them all, but because it doesn't reach the Earth's surface and is instead absorbed by the ozone layer, it poses no threat to those of us living on the ground. The confusion between black light and UV light appears to be caused by UVA and UVB light; nonetheless, differentiating the two is not very difficult. The combined efficacy of the two enables the disinfection of hard surfaces, liquids, and even the air. This is because of the interaction between the two, but more especially the UVB rays, which have a wavelength in the middle of the spectrum and are able to do more damage to the DNA that is housed in our skin.

Filtration of Water Employing Ultraviolet Light

When UV radiation is used for sterilisation, it destroys germs in the same manner that it would damage human skin if we were exposed to it directly. The fact that these viruses, bacteria, fungi, and other undesired particles are unable to withstand the intense UVA and UVB rays is one of the primary reasons why UV light is widely used in a variety of businesses that demand safe and clean water. In these applications, the use of ultraviolet light reduces the amount of chemicals that need to be added to accomplish the same effect. This results in cheaper costs, healthier water for drinking, fish farming, and many other activities, as well as improved environmental sustainability. UV light can also kill microorganisms that cause disease in fish.
