The Basics of LED Lights

Unlike traditional incandescent lamps, LEDs are not sources of white light. However, they do put out light that is monochromatic in nature, which makes them very efficient for applications that use colored lights such as exit signs and traffic lights. Even though LEDs are not sources of white light, white light is still required. White light can be created in a number of ways.

  • The hybrid method can be used, which uses monochromatic and phosphor-converted LEDs.
  • RGB systems can be used in which light is used in multiple LEDs (monochromatic such as red, blue, and green) are blended to create a white light.
  • The conversion of phosphor can be used, which converts colored light into a white light.

LED technology has the potential to create the highest-quality white light with energy-efficiency, which is the primary goal when it comes to researching and developing in the U.S Department of Energy. There are a number of white LED products that are currently available, and the list continues to grow as devices and technology are improving. While a lot of these products are similar in nature, their energy efficiency and quality tend to vary greatly. ENERGY STAR has criteria that will help consumers make wise choices when it comes to their LED lighting needs.

What Makes LED Lighting Different from the Competition?

By the year 2030, LED lighting products have the potential to cut energy use by almost 50%, which helps to save money on energy as well as carbon emissions. LED light bulbs are very small, easy to use, have a long lifespan, and hold up in hot and cold temperatures. These are just a few of the qualities that make LED lighting products so much different than everything else on the market.

LEDs have the ability to emit a certain amount of light into one direction, which decreases the requirement for diffusers and reflectors, which can lower efficiency. If you use a traditional incandescent bulb, they will emit light in a number of directions which uses a lot of energy and makes them not as useful as LED bulbs.

Are LEDs really Energy Efficient?

In order to understand just how energy efficient these products are, there are two factors that must be considered. These two factors are the overall efficiency of the LED device, and how well it is able to work with the fixture in order to provide the right amount of light for the job it is trying to perform. It can also depend on the design of the fixture. If it is designed poorly, even the highest quality LED light bulbs will not be able to work quite as effectively as with a properly constructed fixture.

How long will They Last?

A high quality LED bulb has the ability to outlast traditional light bulbs by nearly 70%. If you purchase products that are of high quality, you can expect them to last up to 50,000 hours. This is compared to the traditional light bulb that only lasts approximately 10,000 hours. This makes them extremely cost-effective. LED light products tend to cost more than the average light bulb, but costs are rapidly decreasing.
