For many years, the only light bulbs available were traditional, incandescent bulbs. The science behind this kind of bulb is fairly simple. An electrical current runs through the bulb. As it passes through the bulb filament, the filament releases energy in the forms of light and heat. Eventually, usually after about 1500 hours in modern incandescent bulbs, the filament breaks and the bulb must be replaced. All this has changed with the advent of LED lighting.
What is an LED light?
Light emitting diode, or LED, lights operate on a different, more complicated principle. When an electrical current travels through the diode, electrons are stimulated and release energy in the form of photons. One of the major differences between LED and incandescent bulbs is that LEDs release light with very little heat.
Lower Energy Use
It is estimated that LED bulbs use 90 percent less energy than incandescent bulbs. Because they release light without heat, they operate far more efficiently. This can make a big difference in a home or business’ electric bill over time.
The light without heat difference also gives LED bulbs a much longer lifespan than other options. Because they use energy efficiently, they do not burn out as quickly. While they will cost a little more for the initial purchase, they will save money for the consumer in the long run. Well-constructed LED light bulbs are estimated to have a useful life of 50000 hours. That number represents over five and a half years of constant lighting. Not only does this save money, but it also saves the time spent in changing light bulbs, especially light bulbs in fixtures that are hard to reach.
Because they do not depend on a fragile filament, LED light bulbs are also quite durable over time. They can be installed in fixtures with some vibration, such as a ceiling fan fixture, without issue. They operate well in cold temperatures so are an excellent choice for outdoor lighting.
As LED technology continues to improve, more options in color and style are coming onto the market. LED bulbs can be found in a variety of colors and multi-colored strings. They can be found in styles that mimic older, traditional bulbs, suitable for overhead lighting, vanity mirrors or any home fixture. More recently, color-changing bulbs have become available. In this bulb, the diode can be programmed to release photons at different frequencies, resulting in many color choices in the same bulb.
LED bulbs will become the standard for residential and commercial lighting. Their flexible, energy-efficient design will make them the lighting choice for many consumers. These bulbs will continue to produce light without heat for years to come.
