  • Day Three: Replace your incandescent bulbs with
    compact fluorescent bulbs.

    How many light bulbs does it take to change the

    The US government's Energy Star program says that
    if every household in the nation replaced ONE
    incandescent light with a compact fluorescent
    (hereafter "CFs") bulb, it would prevent enough
    pollution to equal removing one MILLION
    automobiles from the roads.

    CFs use 66% less energy than standard
    incandescents, and last as much as ten times
    longer. But they give as much light as
    incandescents. (I have compact fluorescent bulbs
    that I installed in the year 2000 that are still

    CFs are cool to the touch, because they are not
    wasting energy making heat.

    Light energy is measured in "lumens", and the
    package of the CF bulb will say how many lumens it
    produces. A 100 watt incandescent is generally
    about 1600 lumens. A 60 watt incandescent is
    about 800 lumens. A CF bulb that produces 1600
    lumens, the equivalent of a 100 watt bulb, will
    only burn about 22-25 Watts of electricity (the
    100 watt incandescent is burning 100 watts). So
    figure a 75% reduction in energy use for lighting
    when you switch to CF bulbs.

    You can get a variety of shades of white in the
    light produced by CFs:

    Warm white -- 2700 Kelvin) very similar to
    incandescent bulb light,
    Soft white -- 3500 K, yellowish-white light,
    Cool white -- 4100 K, more pure white
    Daylight -- 6400 K, slightly bluish-white

    The Kelvin scale is used to describe the colors of
    light. The higher the number, the "cooler" the
    light (that is, the more it is shaded with blue).

    The bulbs do contain a minute amount of mercury,
    but they also reduce the amount of mercury emitted
    into the atmosphere by coal generating plants. I
    have had a few CFs go out on me, I took those with
    me on my regular trip to the Oklahoma City
    Hazardous Waste collection center and they
    accepted them.

    If you have no experience with CFs, I suggest that
    you buy a variety of bulbs with different color
    shades to their lights, and decide what works best
    for you. Generally I like the small "spiral"
    bulbs that have a blue-ish white light, but in my
    office, I have a brighter, more yellow light.

    If you don't find something you like at a local
    store, there is a very large array of CFs lights
    available on the Internet, including colors (red,
    green, pink, yellow) and black-lights.

    People sometimes say, "Don't use them in places
    where you turn the light on and off a lot, such as
    your closets." We use them everywhere, however,
    including our closets, and they work just fine.
    We also use them outside, although there is one
    caveat about that: In cold weather they take
    longer to warm up.

  • I don't think Matthew still advocates using this type of lightbulb...

    Right Matthew?
