Energy Efficient Lighting

Looks complicated… - Identify legislation that affects lighting standards and efficiency - Identify various types of energy efficient lamps (bulbs) - Learn how to shop for lighting and understand how to read the new lighting label … but with a few tips, you can learn how to identify the correct bulb for each need in your house and you can save money!

What does all of this mean to ME?! Among other things, it set new requirements for bulbs: Sets performance standard of light output (lumen) for energy used (watts) Many light bulbs meet the new standards Some traditional incandescent bulbs do not meet the new standards There are many light bulbs that meet the new standards (including energy saving incandescent, CFL and LED), however, there are some common light bulbs that do not meet the new standards. Traditional 40,60, 75 and 100 W incandescent bulbs are less efficient and don’t meet the new standards. These give of 90% heat and only 10% light. More detail about the EISA Lighting Efficiency Standards: Appliance energy efficiency standards for boilers, dehumidifiers, dishwashers, clothes washers, external power supplies, and commercial walk-in coolers and freezers. Lighting energy efficiency standards for general service incandescent lighting in 2012 and sooner for general-service tubular fluorescent lighting and metal halide lamp fixtures. Sets performance standard of light output (lumen) for energy used (watts) Some traditional incandescent bulbs do not meet the new standards. The standards apply to the manufacture or import of bulbs There are some exceptions including 3-way bulbs, appliance bulbs, others The new standards do not affect all bulbs. Various specialty bulbs are exempt, including appliance bulbs, heavy-duty bulbs, colored lights, three-way bulbs, and others. The new energy efficiency standards will affect conventional, pear-shaped medium size screw-in, light bulbs, and some reflector bulbs like the ones we use in traditional lighting fixtures in our homes. In total there are 22 types of traditional incandescent lamps that are exempt. What does all of this mean to ME?!

Lighting Terms Lumen The unit of measure describing the quantity of light emitted from a source of light, for example, a light bulb (lamp). Watt A unit of power denoting the rate at which electricity is used. Efficiency is measured by the number of lumens per watt a bulb provides Before we go any further, we need to define some terms. Lumen is the unit of measure describing the quantity or intensity of light emitted from a source of light, for example, a light bulb (lamp). A watt is a unit of power denoting the rate at which electricity is used. Put the two together, and you get lumens per watt (LPW), also called “efficacy” (often wrongly referred to as efficiency). It is similar to “miles per gallon” for an automobile and is a measure of how effective the light source is in converting the watts or energy into light. Lumen and wattage values are specified on the lamp’s packaging, i.e., 100 watts, 1700 lumens. This helps to identify how bright or dim the lamp is, important because we may want to create a mood through lighting—we typically associate low intensity with a relaxed and intimate atmosphere. Efficiency is measured by the number of lumens per watt a bulb provides. Lumens = Brightness Watts = Energy

Lumens… the new way to shop for bulbs Lets watch a brief video from Energy.gov that explains lumens and how to shop for the right bulb for different needs in your home. http://energy.gov/public-services/homes/saving-electricity/lighting

This is what the new lighting labels look like This is what the new lighting labels look like. (Go over the 6 components) EISA: New Labels

Known as the screw-in "A"-type light bulb, standard incandescent lamps are the most common—but most inefficient—light source available. These standard incandescent lamps produce light from a tiny coil of tungsten wire that glows when it is heated by an electrical current. Larger-wattage incandescent bulbs have a higher efficacy than smaller-wattage bulbs. However, a larger-wattage lamp or bulb may not be the most energy- or cost-effective option, depending on how much light is needed. "Long-life" bulbs, with thicker filaments, are a variation of A-type bulbs. Although these bulbs last longer than their counterparts, they are less energy efficient.

Lighting Choices: CFL’s ENERGY STAR-qualified CFL’s use about 75% less energy and last 10 times longer than comparable traditional incandescent bulbs Available in range of colors including warm tones https://energy.ces.ncsu.edu/2016/02/recycling-cfl-lightbulbs/

Lighting Choices: LED ENERGY STAR qualified LEDs use 75-80% less energy and last 25 times longer than traditional incandescent bulbs More expensive, however cheaper to operate and last longer

Why is Recycling CFLs Important? Recycling prevents the release of mercury into the environment.  CFLs and other fluorescent bulbs often break when thrown into a dumpster, trash can or compactor, or when they end up in a landfill or incinerator.    Other materials in the bulbs get reused.  Recycling CFLs and other fluorescent bulbs allows the reuse of the glass, metals and other materials that make up fluorescent lights. Virtually all components of a fluorescent bulb can be recycled. Your area may prohibit disposal and/or require recycling.  Some states and local jurisdictions have more stringent regulations than U.S. EPA does, and may require that you recycle CFLs and other mercury-containing light bulbs. Visit search.Earth911.com to contact your local waste collection agency, which can tell you if such a requirement exists in your state or locality.  We are aware that the following states prohibit mercury-containing lamps from being discarded into landfills search.Earth911.com

You are bound to have questions…. This Energy.gov website (go to link on bottom of slide) is very helpful in answering questions about lighting. Lets explore this site for a moment so you are familiar with the types of resources you can find on this website. (click on 2 or 3 of the questions on the website to give the participants an idea of the resources available. Do not spend time reading the Q&As, just show that they are available and useful.) http://energy.gov/energysaver/articles/frequently-asked-questions-lighting-choices-save-you-money

Home Energy 101 Lets watch a video at Energy.gov that explains how to choose a new bulb and how the new lighting options can save energy, saving YOU MONEY.

Warm vs. Cool The color wheel Warm colors feel “cozier” and welcoming Basic “map” for color theory A circular arrangement of the spectrum Warm colors feel “cozier” and welcoming Cool colors evoke a more tranquil mood Warm vs. Cool—the Psychology of Light Warm and cool descriptions refer to the way color groups are perceived—the psychological impact of lighting. Colors and light sources from the violet/blue end of the spectrum are referred to as “cool,” and those toward the red/orange/yellow side are “warm.” www.krylon.com/color/theory/

Color Rendition Fluorescent light does not have to be “cold” Color rendition is very important. Different light sources will make colors appear differently. Incandescent lighting has been referred to as warm light. At one time, fluorescent lamps were unpopular because they were seen as cold light. This has changed, however, and fluorescent lamps are now available in many different shades of white. By varying the phosphor blend, colors can be made to vary from warm to cool and several steps in between, allowing one to select the best match for the use and physical characteristics of a space. If a space has lots of reds, oranges, yellows, or woods, one would choose a warm color; conversely, with lots of white, blues, grays, or metal, cool colors may be preferable. An in-between neutral color is also available. Fluorescent light does not have to be “cold”

Remember Key Points: Shop for lumens, not for watts Color rendition is affected by lighting, and lighting comes in various temperatures/color
