Compact Fluorescent Light Bulbs

CFLs vs. Incandescent Light Bulbs

CFLs last 10 times longerUse roughly ¼ the energyProduce 25% less heat while producing more light per wattSave 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

Types of 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

CFLs do contain a small amount of mercuryIn U.S., major source of mercury emissions is electricity useCFLs use less electricity than incandescent bulbsCFLs 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.

Proper Disposal

Spent CFLs should be recycledFor CFL recycling locations visit/contact:http://earth911.com/http://www.recycleabulb.com/locations/ Local utility companyCounty 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 energySaving energy helps the environmentSaving energy can save YOU moneyCFLs have a longer bulb life than incandescent bulbsCFLs 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.
