Get Glowing with UV Lights

A common sight at party halls, dance floors, and bowling lanes, UV lights make white clothing glow, changes the appearance of skin, and emits a deep-blue haze while glowing. These are known as “black lights” and are ideal for livening up the party. However these lights have many other uses that are more practical, and can be highly beneficial to dermatologists and their patients, crime scene investigators, and air conditioning manufacturers.

The Light of the Party

Dance floors and night clubs often used UV lights or “black lights” for their ability to give “glow” to clothing and skin, and to provide an atmospheric, dark-blue haze. Additionally, many of these can be programmed to turn off and on rapidly, which produces a strobe-like effect. This is popular with dance clubs and at many large gatherings where a party-type atmosphere is desired. Additionally, these same lights used for parties also attract insects due to their blue tint. The main reason for whites and certain colors or clothing glowing under UV lights is due to certain phosphorous properties present. For instance some clothes washing powders use phosphorescent chemicals to make white clothing whiter.

CSI: Crime Scene Investigation

UV lights are commonly used in real life by investigators and pathologists to get more detail from the crime scene than can be seen by just looking at the area with the naked eye. Even with a modern-day black light, investigators can detect dried bodily fluids such as semen, blood, and saliva. These fluids will glow when exposed to ultra-violet light, and will provide information regarding where fluids landed on the surface, and how much of the fluid is on the floor. The orange glasses often seen on TV crime shows block 99% of normal light in the area, and this highlights any glowing substance.

Air Cleaning Service

Air cleaners are becoming a more common sight in families’ homes, and these machines claim the ability to remove harmful viruses and irritating pollen molecules roaming the air around the house. Chances are the machine cleaning the air inside the air cleaner itself is an ultra-violet light. UV lights convert pollen, spores, and airborne pathogens into harmless byproducts when shone at an intense level of 240 to 280 nm. UV has also been proven to remove carbon monoxide from the air, however, the amount of light intensity necessary for this is not yet practical for home use.

Skin and UV Lights

Hospitals often provide UV rooms in which patients are exposed to UV rays for therapeutic purposes. This process is called phototherapy, and regular sessions of this have been shown to cure such skin diseases such as psoriasis, vitiligo, and eczema. Phototherapy requires no use of medication – the light itself is enough to cure most skin problems. Although there is no evidence that cancer is linked to use of UV light, hospitals recommend staying away from natural UV sources when receiving phototherapy to reduce skin redness or the possibility of developing cataracts.

Overall, the use of UV lighting offers a variety of benefits, from curing skin diseases to air cleaning and even curing nail gels.
