There are many light bulbs out there that give off Ultra Violet (UV) radiation; however, LED light bulbs are not one of them. This is one of the biggest selling points and most desirable qualities that people consider when switching from CFL bulbs to LED bulbs. Most people who use CFL bulbs have started doing so because of the money savings that are involved with lighting their home with a less energy consuming bulb.
LED Lights of the Past
At one time LED lights could only be seen on things like remote controls, microwave ovens, telephone systems, and other electronic devices. They had never been considered sufficient for use as a home or office light bulb. In past years, LED technology was very basic, and most people never even considered the idea of creating lights that could replace incandescent bulbs. Some of the earlier models of LED light bulbs failed, leaving scientists feeling discouraged. Complaints about LED lights being too dim or dimming in a short period of time, forced researchers to work even harder.
Modern LED Technology
In the 1990s developers began working on LED lights, and inventing new and exciting ways to make them brighter. In recent years, breakthroughs in LED technology have allowed scientists to perfect LED light bulbs to make them a better alternative lighting source for both homes and offices. Now, LED light bulbs are seen in stores everywhere as a safe alternative to incandescent, as well as CFL, light bulbs. While UV radiation is a major concern, the fact that CFL bulbs contain Mercury is also a concern that is turning a lot of people away from them, and causing them to switch to the newer LED light bulbs.
Effects of UV Radiation
Ultra Violet light is a portion of the light spectrum that is generated by the sun. In normal everyday activities, a small amount of this light is required for people to survive. The sun provides essential nutrients such as vitamin D. With that said, over exposure to the sun has been associated with a number of problems, from severe sun burns to skin cancer. Fluorescent tubes and CFL light bulbs also produce these harmful rays, however, since the ones coming from the bulbs are artificial sources of light there are absolutely no health benefits found in them. Instead, they have been determined to cause such problems as damage to the eyes and skin cancer.
Perhaps in the years to come, LED light bulbs will become the only source of artificial light that people use. It may take some time for the general public to realize the many advantages of LED light bulbs, and how superior they are in terms of safety, durability, and energy conservation. However, the best way to start is one home at a time. It is very important for the public to be aware of things that can be potentially dangerous to their health, as well as to the health of the people they love. Perhaps doing something as simple as changing the way we light our homes will be the one thing that truly makes a difference.
