Introduction to Home LED Lights
If you are considering replacing your existing incandescent light bulbs or CFLs with bright LED lights, then it is a good idea to learn about pros and cons of each of these different types of home lighting products.
To start off, I would like to say that modern LED light bulbs can provide a reasonably good new light bulb replacement option. Without a doubt, LEDs offer a number of important benefits, but you may also find that CFLs, which you can now buy for around $4.00 a piece, may be more appropriate for your current situation.
What is LED Lighting?
A LED or a Light Emitting Diode is a form of lighting that is becoming increasingly popular as an environmentally preferred source of lighting in both residential and commercial buildings. A LED is a type of semiconductor that can produce light through an affect known as electroluminescence. LEDs are compact lights that do not contain filaments like incandescent bulbs, and which emit mostly light while producing very little heat as a by product of their operation. LEDs are typically small, sometimes measuring less than one millimeter square. LED lighting can take a number of different forms, using various lenses to create different lighting effects by manipulating how the light radiates and disperses.
The earliest LEDs, which were produced during the 1960s, were only capable of emitting red light, and they were typically only used as indicator lights incapable of producing enough light to light up the space. LED lights of different colors such as yellow were later obtained. Early LEDs were mainly used only as indicators in calculators, and scientific instruments, and TV remotes, and as indicator lights in automobiles and in airplanes.
A significant technological breakthrough of 1995, resulted in a bright white LED light bulb capable of lighting up the space with a light that was of adequate intensity and reasonably close to white/natural light.
Modern LEDs can produce light of all different colors (wave lengths of the color spectrum), including visible, ultraviolet and infrared light. The brightness and efficiency of LEDs has been improved significantly with the advancements in technological development of LEDs. Thus, modern LEDs are now being used not only as indicators for displays, but also as a lighting source in our homes and commercial/institutional buildings.
