Energy-efficient lighting -

While LED lamps emit visible light in a very narrow spectral band, they can produce "white light". This is accomplished with either a red-blue-green array or a phosphor-coated blue LED lamp. LED lamps last 40, to , hours depending on color. The current challenges of the LED source are a poor Color Rendering Index CRI of 65 or lower and poor efficacy, often less than 30 lumens per watt.

LED lamps have made their way into numerous lighting applications including exit signs, traffic signals, under-cabinet lights, and various decorative applications.

Though still in their infancy, LED lamp technologies are rapidly progressing and show promise for the future. For more information on LED lighting and other solid state lighting technologies visit the Department of Energy Solid State Lighting.

Rapid start ballasts are the most common type of fluorescent ballast. These ballasts offer a long lamp life at a reasonable cost. They have been used for years with lighting controls to provide energy savings.

Instant start ballasts are usually the least expensive ballasts on the market. The efficiency of instant start ballasts is higher than rapid start ballasts, but lamp life is shorter, especially when the frequency of starts is increased due to the use of controls. They are often used where energy savings is the primary goal and lights are on continuously for very long periods of time.

One advantage of the instant start ballast is that the lamps are wired in parallel, so that when one lamp on a multi-lamp ballast burns out, the others remain illuminated. Program rapid start ballasts are some of the best to use for energy efficiency and long lamp life. These ballasts are slightly more expensive than standard rapid start ballasts, but use a "gentler" starting method so that frequent starting lessens the reduction in rated lamp life.

These ballasts are recommended for smaller diameter fluorescent lamps and compact fluorescent lamps. With the right lighting controls scheme, program start ballasts can provide significant energy savings. Dimming electronic ballasts for linear fluorescent lamps usually fall into two categories.

This ballast is commonly used when the lowest light levels are not needed, or to achieve energy savings by dimming the lights when there is plentiful daylight. This ballast is used in situations where lower light levels are desired.

Electronic high-intensity discharge ballasts HID for metal halide lamps are now available for most lamps up to watts. These ballasts should improve lamp performance and offer a limited range of dimming to achieve some energy savings.

An efficient luminaire optimizes the system performance of each of its components. There are a few types of luminaires that offer opportunities for energy conservation in a lighting system design. Many of these provide indirect light to brighten the ceiling or are designed to brighten walls or task surfaces.

Most of them are fluorescent and are easily controlled for further energy savings. Some examples are shown in the table below. Energy efficient lighting can be installed in new construction, modernization, and repair and alternation projects. It is applicable to all building types and space types, particularly educational facilities , office buildings , health facilities , research facilities , warehouses , libraries , and courthouses.

There are several programs in place to provide design guidelines and recognition for energy-efficient buildings. Many of these are government-supported. Energy Star® Program : This program, supported by the U.

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.

Lighting basically has two components— bulbs and fixtures. Sometimes, these are integrated, with the fixture including a built-in light source or bulb. ENERGY STAR certified lighting products have big benefits over standard ones.

They are designed and rigorously tested to last longer, provide better light quality, offer better compatibility with other products, and have warrantees to back them up.

Make the switch to ENERGY STAR certified light bulbs, fixtures and decorative light strings like Holiday lights to cut your electricity bill and reduce your carbon footprint. It is important to be sure that the bulb you choose uses the least amount of energy to produce the maximum amount of light.

Meanwhile, your fixtures should use the least amount of energy to operate the light source in them. The easiest way to do this is to select an ENERGY STAR certified product. Find certified products using the ENERGY STAR Product Finder.
