Why LED

• The U.S. Department of Energy estimates that rapid adoption of LED lighting in the U.S. over the next 20 years can:

• Deliver savings of about $265 billion. • Avoid 40 new power plants. • Reduce lighting electricity demand by 33% in 2027.

LED LIGHTING

Low-Powered LEDsLEDs used to draw attention to something, such as an exit sign, a green power button on a computer, or a red blinking light on a video camera.High-Powered LEDsLEDs used to illuminate an area. ENERGY STAR qualified LED lighting uses multiple illuminator LEDs inside a fixture to produce white light.

Poor LED lighting design

Bad design can lead to a wide range of problems, some immediately observable and some not. Poorly designed products often come with exaggerated claims while failing to deliver on the quality specifications above.

An ENERGY STAR qualified LED bulb:• Uses

ENERGY STAR LED Lighting

• Uses at least 75 percent less energy and lasts at least • 15 times longer than an incandescent bulb. • Has efficiency as good as or better than fluorescent

lighting. • Turns on instantly – there is no warm-up time. • Allows for precise placement of light due to the

directional nature of LEDs. • Produces far less heat than an incandescent, which

can reduce air-conditioning needs. • Is durable – performs well outdoors and in cold

temperatures• No Mercury• No UV rays that can damage artifacts and paintings

Energy Star LED Lighting

• Brightness is equal to or greater than existing lighting technologies (incandescent or fluorescent) and light is well distributed over the area lighted by the fixture.

• Light output remains constant over time, only decreasing towards the end of the rated lifetime (at least 35,000 hours or 12 years based on use of 8 hours per day).

• Excellent color quality. The shade of white light appears clear and consistent over time.

• Efficiency is as good as or better than fluorescent lighting. • Light comes on instantly when turned on. • No flicker when dimmed. • No off-state power draw. The fixture does not use power when it is

turned off, with the exception of external controls, whose power should not exceed 0.5 watts in the off state.

Energy Star LED Lighting

• Reduces energy costs — uses at least 75% less energy than incandescent lighting, saving on operating expenses.

• Reduces maintenance costs — lasts 35 to 50 times longer than incandescent lighting and about 2 to 5 times longer than fluorescent lighting. No bulb-replacements, no ladders, no ongoing disposal program.

• Reduces cooling costs — LEDs produce very little heat. • Is guaranteed — comes with a minimum three-year warranty — far

beyond the industry standard. • Offers convenient features — available with dimming on some indoor

models and automatic daylight shut-off and motion sensors on some outdoor models.

• Is durable — won’t break like a bulb.

• A Joint IES – ANSI committee developed the standard test procedure

• Approved method describing procedures and precautions in performing reproducible measurements of LEDs:

• total flux, • electrical power, • efficacy (lm/watt), and • Chromaticity

LM - 80

• Approved method for measuring lumen depreciation of solid-state (LED) light sources, arrays and modules

• Does not cover measurement of luminaires.

• Does not define or provide methods for estimation of life.

“Operational failure”Most light sources “burn out” (End of “Life”)Lamp life is typically

rated at 50% failure rateLEDs typically don’t fail

(no filament to “burn”)

Lighting Facts Label - FTC

• Under the new rule, the back of each package of light bulbs will have a “Lighting Facts” label modeled after the “Nutrition Facts” label that is currently on food packages. The Lighting Facts label will provide information about:

• brightness; • energy cost; • the bulb’s life expectancy; • light appearance (for example, if the

bulb provides “warm” or “cool” light); • wattage (the amount of energy the

bulb uses); and whether the bulb

contains mercury.

DOE Findings

• CALiPER Program • Solid-state lighting (SSL) technologies today are changing and

improving rapidly, and products arriving on the market exhibit a wide range of performance. There is a need for reliable, unbiased product performance information to foster the developing market for high-performance SSL products.

14

DOE Findings

• Summary Reports• DOE conducts at least two rounds of CALiPER testing each year, and

more than 300 products have been tested through the program to date. A Summary Report is published following completion of each round which provides analysis of the test results for all products included in that round. Download CALiPER Summary Reports.

• Detailed Test Reports • Detailed Reports provide extensive data on individual products tested

through the CALiPER program and are distributed in the public interest for non-commercial, educational purposes only. Detailed Report information can be accessed through an online system with both basic and advanced search options.

15

DOE Caliper Testing

• Benchmark Reports• CALiPER Benchmark Reports, published periodically, provide detailed

analysis of test results for both traditional (non-LED) and LED products for a given application, comparing a range of standard lighting measures. Download CALiPER Benchmark Reports.

qualified laboratories.
