cfls vs incandescent 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
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
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
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
Color
  • Kelvin (K)
  • More yellow-colored – lower K number
  • Whiter- or bluer-colored – higher K number

tips for using cfls
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
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.

  • ENERGY STAR Website www.energystar.gov
  • KY Division of Waste Management 502-564-6716
  • County Solid Waste Coordinator
proper disposal
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
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
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.
