Compact Fluorescent Light Bulbs


CFLs vs. Incandescent Light Bulbs

  • CFLs last 10 times longer

  • Use roughly ¼ the energy

  • Produce 25% less heat while producing more light per watt

  • Save YOU $$$


Purchasing CFLs

  • Check the label

    • Equivalent incandescent bulb wattage

    • Where the bulb can be used

    • If the bulb is rated as an ENERGY STAR qualified bulb

    • If the bulb is “dimmable” or “three-way”

  • For photo cells, motion sensors, and electric dimmers, check with manufacturer of the control.


ENERGY STAR

  • Promotes products which are energy efficient

  • Look for ENERGY STAR logo on appliances, computers and electronics, heating and cooling equipment, lighting and fans, and plumbing equipment

  • www.energystar.gov


Types of CFLs

  • Available in a variety of styles, sizes, and wattages

    • Spiral-shaped

    • A-shaped

    • Globe-shaped

    • Tubed

    • Candle

    • Indoor reflector

    • Outdoor reflector


Color

  • Kelvin (K)

  • More yellow-colored – lower K number

  • Whiter- or bluer-colored – higher K number

Tips for Using CFLs

  • Hold CFL by ballast (white plastic part) not glass tubing

  • Keep CFLs on for 15 minutes or longer

  • If CFL is NOT marked as “dimmable” or “three-way” do NOT use in dimmable switch or three-way socket

  • Most CFLs do not work with photo cells, motion sensors, and electric dimmers – check with manufacturer of these controls

  • Place CFLs in open fixtures indoors

  • When using CFLs outdoors, check packaging labels for optimal operating temperatures, and place bulbs inside enclosed fixtures to safeguard from weather


Mercury

  • CFLs do contain a small amount of mercury

  • In U.S., major source of mercury emissions is electricity use

  • CFLs use less electricity than incandescent bulbs

  • CFLs result in less total mercury emissions than incandescent bulbs

The amount of mercury in a CFL is roughly equal to the amount of ink on the tip of a ballpoint pen.


Cleaning Broken CFLs

  • Saving Money and Energy: Compact Fluorescent Light Bulbs Publication

  • ENERGY STAR Website www.energystar.gov

  • KY Division of Waste Management 502-564-6716

  • County Solid Waste Coordinator


Proper Disposal

  • Spent CFLs should be recycled

  • For CFL recycling locations visit/contact:

    • http://earth911.com/

    • http://www.recycleabulb.com/locations/

    • Local utility company

    • County Solid Waste Coordinator

In 2008, Home Depot® launched a nation-wide campaign offering free recycling of spent CFLs. Simply bring your spent CFL to any Home Depot® location.


Advantages of CFLs

  • CFLs save energy

  • Saving energy helps the environment

  • Saving energy can save YOU money

  • CFLs have a longer bulb life than incandescent bulbs

  • CFLs produce less heat than halogen or incandescent bulbs


Disadvantages of CFLs

  • CFLs cost more than traditional incandescent bulbs.

  • Many CFLs have an initial low light output meaning that they have to warm up before they reach their full light potential.

  • When compared to incandescent bulbs, CFLs have a poorer quality color rendition. Color rendition refers to the light quality, and is defined by the U.S. Department of Energy as “How colors appear when illuminated by a light source.”

  • Incandescent bulbs project light further than CFLs.

  • CFLs contain mercury, thus they must be disposed of (recycled) properly.

  • Not all CFLs can be used in a dimmable switch or three-way socket.

  • CFLs may not work with photo cells, motion sensors, and electric dimmers.
