Find eligible commercial light fixtures. LEDs allow for dimming and color-tuning. Studies of K schools have shown these features to contribute to an improved working environment for teachers and the students. In particular, children with autism spectrum disorder were shown to benefit from additional lighting cues to transition between certain activities.

If your business serves food, heat from traditional lighting can impact food quality and freshness. Switching to LEDs can save you more than energy—it can save both product and money. You are here Home Commercial Buildings Save Energy Ways to Save Upgrade Your Lighting.

The Perks of LED Lighting With LED lighting, you can greatly reduce the electricity used by your commercial building with many light fixtures available to meet a wide variety of needs and applications. Compact fluorescent lamps CFL are often used as simple substitutes for incandescent lamps due to their significantly longer life and better energy efficiency.

Self-ballasted, "screw-in" retrofit CFL lamps are sometimes used in the energy saving retrofit market. Also, retrofit lamps cannot be dimmed. However, the performance of screw-in lamps is usually not as good as the separate lamp and ballast combination. Due to their small size, CFL lamps are used in recessed luminaires, wall and ceiling mounted fixtures, and even track lighting and task lighting.

The diffuse nature of the fluorescent lamp makes the CFL lamp a good choice for downlighting and wall lighting also referred to as "wall washing". Low mercury fluorescent lamps can be disposed of in landfills in some states.

However, many states have legislation pending that would not allow the disposal of any product containing mercury in a landfill. Specifying a low mercury product and then recycling that lamp at the end of its life offers the best environmental solution to disposal of mercury-containing lamps.

There are many parts to a standard fluorescent lamp that can be recycled, including the glass, metal, mercury, and phosphor. Inductive fluorescent lamps are white light sources with very good color rendering and color temperature properties. These lamps are energy efficient and offer extremely long life over , hours , good lumen maintenance characteristics, and instant-on capability.

The lamp enclosure is called a "vessel" and shapes vary coated on the inside with phosphor. Dimming is already available in Europe and will be available in the near future in the United States. They are powered by a small generator about the size of a fluorescent ballast attached to the lamp via a short fixed-length cable.

The generator induces a current in the lamp which causes it to glow—there are no electrodes to wear out.

The larger, diffuse nature of these sources makes them excellent for lighting larger volumes and surfaces. They are often used in place of low- to medium-wattage high intensity discharge sources because of the instant-on capability and reduced maintenance associated with the longer lamp life.

This lamp source has promising application for indoor and outdoor lighting applications. High-intensity discharge lamps HID are still one of the best performing and most efficient lamps for lighting large areas or great distances. Metal halide white light lamps are replacing high pressure sodium lamps in many outdoor applications because white light sources can be 2 to 30 times more effective in peripheral visual detection than yellow-orange sources like high pressure sodium.

Pulse initiated, or "pulse-start" metal halide lamps provide better color stability and longer life than previous technologies. PAR metal halide lamps with ceramic arc-tube enclosures are commonly used for accent lighting and highlighting in large spaces, and are now commonly used in retail applications.

The small size of the metal halide arc-tube allows for excellent optical control. However, the extreme brightness of the metal halide lamp requires careful shielding and design. Different HID metal halide lamps.

Some HID lamps called "hot restrike" are special in that they can be restarted immediately after being turned off, but if they are allowed to cool down, they will take about 15 minutes to warm up just like regular lamps.

Incandescent lamps are still used for accent and specialty lighting, where the warm color, controlled brightness, instant-on, and dimming capabilities of these sources is needed.

Incandescent lamps can provide a "sparkle" that is not characteristic of more diffuse fluorescent sources. PAR and low-voltage lamps can provide good beam control, and if dimmed, can also provide a reasonable lamp life.

However, because of their lower energy efficiency and shorter lamp life, incandescent lamps should be used carefully for lighting of specific features. Some of the most effective lighting designs balance a small quantity of incandescent accent lighting with a fluorescent ambient general lighting system.

LED lamps are the newest addition to the list of energy efficient light sources. While LED lamps emit visible light in a very narrow spectral band, they can produce "white light". The best and effective solution for energy conservation is the adoption of energy efficient lighting technologies in the lighting sector, which facilitates comprehensive redesigning of lighting and control systems.

There have been major improvements and innovations in lighting technologies which can offer a great potential for energy savings in many lighting applications such as household lighting, street lighting, hospitality and retail spotlights, office and industrial lighting, etc.

The following are the techniques or types of energy efficient lighting which are commonly practiced as energy-saving opportunities. Energy efficient lamps can deliver the same amount of lighting with greater energy saving at low cost, when compared with conventional lamps.

Traditional incandescent lamps consume a lot of energy to produce light in which 90 percent of consumed energy is given off as heat and also they consume more energy, typically times more than the actual amount to produce light.

Energy efficient lamps overcome these problems by offering many more advantages than incandescent lamps. The two most popular choices of energy efficient light bulbs include CFLs compact fluorescent lamp and LED light emitting diode lamps.

CFL lamps are miniature or curly versions of long-sized fluorescent tubes. These lamps combine the efficiency of fluorescent lighting with the popularity and convenience of incandescent fixtures. They screw in to the fixtures that allow all standard incandescent lamps, but not into standard fluorescent fixtures of long tubes.

Depending on the brand and application use, they come in different range of styles, colors and sizes. CFLs use 75 percent less energy and produce 75 percent less heat for producing the same amount of illumination as compared with incandescent lamps. They last 10 to 15 times longer and cost 10 to 20 more as compared to incandescent lamps.

These lamps are made with a phosphorous glass tube consisting of inert gas argon and mercury vapor. They use an electronic ballast to create high voltage during the starting and it can be a separate unit or permanently built in lamp.

Some special and older models of CFLs come with separate ballast while some CFLs come with inbuilt ballast. When an electric current is passed through the electrodes, the electrons that are bound to mercury atoms are excited which in turn emits ultraviolet light.

As UV light strikes the fluorescent coating, it will be converted into visible light. Comparison chart for incandescent, CFL and LED bulbs. Some of these are spiral lamps, triple tube lamps, standard lamps, globe lamps, flood lamps and candelabra lamps.

In case of replacing incandescent lamps, CFLs are chosen to match lumens that indicate the amount of light being generated as shown in figure below.

These are available in a variety of light colors such as warm white and soft white, cool white and bright white, etc. depending on the type of application. The table below illustrates a range of light colors of CFLs for specific application. LEDs are solid state semiconductor devices and are more energy efficient than even CFLs.

They produce little heat and higher quality lighting than any other lamp. At the time of inception the usage of LEDs was limited as single bulb indicators in electronic circuits.

Later a number of LEDs are clustered to develop small lamps in battery powered devices such as charging lights, flashlights, etc. Today, LED lamps are available in many new bulb styles which are bright enough to replace traditional incandescent lamps.

LED lamps use 75 percent less energy than traditional incandescent and 50 percent less energy than that of a CFL. They can last times longer compared to incandescent and up to four times longer than a CFL. Unlike incandescent and CFLs, LED lamps produce no heat and hence they are cool enough to touch.

But, these are more expensive; however, they are affordable over the long run. LEDs are made up of semiconductor materials to form PN junctions.

Whenever current flows across these junctions, it releases the energy in the form of a light.
