Ultraviolet light, also referred to as UV light, is a form of light that’s part of the electromagnetic spectrum with a wavelength ranging from 100 to 400 nanometers.

This means that its wavelength is shorter than visible light but longer than X-rays. Although UV light is invisible to the human eyes, humans can now harness their power and energy. Research has proved that people can benefit fro UV light in various ways.

Let’s look at the multiple uses of UV lamps in the commercial, industrial, and healthcare sectors.

Top 5 Uses of UV Light

1. Skin Treatment And Tanning

The indoor tanning industry commonly uses UV light as it stimulates the production of vitamin D. The light replicates the impact of sunlight on the skin and needs only about 20 minutes to tan the desired area of the body. Medical clinics use UV light therapy to cure various skin conditions. These include smallpox lesions, vertigo, psoriasis, eczema, and pruritus.

Having said that, too much exposure to UV light can cause skin cancer. So, it’s important to find the optimum amount of exposure and consult with a dermatologist annually if you’re receiving UV treatment regularly.

2. Fluorescent and Lighting

A number of substances absorb the UV light’s energy and convert it immediately into visible light. This force is called fluorescence.  For example, the ink in highlighter pens contains a fluorescent dye that enables the ink to glow strongly in the dark when a UV lamp is projected on it.

Similarly, UV lamps can be extremely handy to inspect surfaces and material. It can be used as analytical tools by detectives and authorities to check documents and forged banknotes.  Additionally, UV lamps can provide efficient lighting in offices and homes and are often used at nightclubs for effect.

3. UV Light Disinfection and Germ Control

UV lamps are an efficient and safe way to disinfect water without using harmful chemicals that cause pollution in rivers and oceans. The light actively destroys the bacteria’s capacity to reproduce. This method is way more efficient than boiling water as it can also get rid of chloramine and chlorine from waters. As a result, UV germicidal light applications are used in drinking water treatments, pools, and spas.

This application can also kill germs found on utensils, worktops, and equipment. Many commercials industries use this technique to avoid food poisoning, cross-contamination, and to increase the shelf life of fruits and vegetables to preserve their nutritional value. Most importantly, UV technology complies with FDA safety regulations and strict local codes, so it’s 100% secure.

4. UV Light Air Cleaning and Bug Eradication

Ultraviolet light is used in air purifiers to kill mold, germs, and viruses that float in the air. Many homes and organizations such as hospitals install UV light technology in their air conditioning system as a method to sterilize pathogens that can cause respiratory ailments.

UV lamps are highly useful to kill bugs indoors. Unlike humans, insects like wasps, mosquitoes, and houseflies can actually see the UV light. As a result, they are attracted to the light that’s installed in a modern bug zapper and become electrocuted once they come into contact with the electric grids.

5. Indoor Gardening

Just because indoor plants and crops don’t have access to natural sunlight, it doesn’t mean that they can’t have the same benefits as those growing outside. Indoor UV lights can create these rays artificially so that you can replicate optimal growing conditions. If used correctly, it can be extremely beneficial to plants.  It will increase their root mass, cause more branching, increase resistance to bacteria and fungus as well as improve their taste and smell.

Additionally, the production of polyphenols also helps in the production of medical cannabis and improves its medicinal properties.

UV light is extremely versatile. It’s not just for industrial and commercial appliances, but it is also benefiting people in their day to day lives.
