    I just installed a couple of these in my lamp. I had two lamps on a floor lamp in my living room. That, and the windows is my only source of lighting in here. The 2 60-watt bulbs were fine in the summer when there was lots of light but it has been so dark in here and the two bulbs just weren’t making it bright enough to see clearly, It doesn’t help that my new keyboard is black. The keys are a lot harder to see (and no I can’t type without looking)

    So I installed 2 13-watt incandescent bulbs into two of the fixtures.

    WOW what a difference. With just 1 bulb lit the room is so much brighter. I don’t even have to use the second bulb.

    Added bonus:

    • It doesn’t cost as much in energy to use over its lifetime.
    • It costs more to buy but lasts for years
    • It doesn’t heat up the lamp fixture which is metal and I have to be careful of not touching the metal when I turned of the lamp with the old bulbs

    Compact Fluorescent Light Bulbs

    If every American home replaced just one light bulb with an ENERGY STAR, we would save enough energy to light more than 2.5 million homes for a year and prevent greenhouse gases equivalent to the emissions of nearly 800,000 cars.

    Earning the Government's ENERGY STAR

    ENERGY STAR qualified CFLs:

    • Use at least 2/3 less energy than standard incandescent bulbs to provide the same amount of light, and last up to 10 times longer.
    • Save $30 or more in energy costs over each bulb's lifetime
    • Generate 70 percent less heat, so they're safer to operate and can cut energy costs associated with home cooling.
    • In addition to other quality requirements, must turn on instantly, produce no sound, and fall within a warm color range or be otherwise labeled as providing cooler color tones.
    • Are available in different sizes and shapes to fit in almost any fixture, for indoors and outdoors.

    Where to Use CFLs:

    • To get the most energy savings, replace bulbs where lights are on the most, such as your family and living room, kitchen, dining room, and porch.
    • Some CFLs have trouble operating in enclosed fixtures. Check the CFL's packaging for any restrictions on use.

    How to Choose the Right Light:

    Matching the right CFL to the right kind of fixture helps ensure that it will perform properly and last a long time. Read the packaging to be sure that the type you choose works for the fixture you have in mind. For example:

    • If a light fixture is connected to a dimmer or 3-way switch, select CFLs that are labeled for this use
    • For recessed fixtures, it is better to use a 'reflector' CFL versus a standard-shaped bulb.
    • Choose the color that works best for you. For example, while most CFLs are created with warm colors for your home, you could choose a cooler color for task lighting.
    • To get a CFL with the right amount of light, choose one that offers the same lumen rating as the light you are replacing. The higher the lumen rating, the greater the light output. Use the table below to see how lumens can generally be compared.

    Remember, saving energy prevents pollution. When you use less energy at home, you lessen greenhouse gas emissions in our atmosphere. Every CFL can prevent more than 450 pounds of emissions from a power plant over its lifetime.

    i've replaced every bulb in da house with these things. between my s.i.l. and us, i think the whole house is changed over except for outside lights. if you really want some savings (energy) look into led relacements. thats l.e.d. (light emitting diode) even less than florecents for energy consumption.

    Every light fixture in my mobile home has/uses CFL lights - but not just any CFL - I have had to look for the ones that have a 'blue hue' to them - as opposed to the 'orange' CFL's.

    The blue ones are marketed as 5500k - or somesuch. These output a softer more relaxing - to the eyes - light. The orange ones are more harsh - and actually hurt my eyes to use.

    The electric bill has dropped as a result - and the heat from the lighting in the summer has also dropped to negligible amounts.

    My wife - when I first met her - seemed to think I was a bit wacky - and eccentric - with my 'preaching' flourescent lighting - but she has been 'converted' - and fully supports my eccentricity with CFLs.

    I am also working on LED lighting - as we have made several LED products where I work (as far back as 2002), and I am looking to place a solar panel outside to recharge a battery - and attach several high-powered LEDs to it - placing them off-grid - using the battery to power them - and recharging the battery in the day time, from the sun.

    The light from the LEDs that I am going to use rivals that output by the CFLs - and uses a bit less power. The most difficult part of the equation is dissipating the heat that the LEDs generate - and I believe that I have figured that one out. *wide grin*

    Hey Jim,

    Just wondering if you could give me a very rough guesstimate of a percentage difference of heat output between CFL and LED vs. standard bulbs? I'm not sure if I'm asking that right, so I'll try for an example:

    Lady Lee said: Generate 70 percent less heat, so they're safer to operate and can cut energy costs associated with home cooling.

    So if that figure is correct, and a CF generates 70% less heat than a conventional bulb (personally I think that percentage is higher given the one that we have, it runs very cool), would an LED generate something like 60% less heat? Or are they closer in heat output to a regular bulb?

    Thanks

    I was a huge fan of the Compact Fluorescent bulbs when I first got them, but then they started to dim on me. They start out fine -- nice, bright light. But over time (a month? 2?) they don't give off as much light. I didn't know about the LED's, maybe I'll give that a shot.

    As for heat, they don't produce much at all. I just reached up and touched one to see. They don't burn me.

    Hmmmm... I wonder if that stove is hot?...

    CFL's are longer then regular bulbs and they don't fit into any of the fixtures in my house.

    I've used them in my old house though, and i love how long they last.

    I prefer the blue tone ones too, but they are hard to find.

    Dave said - "As for heat, they don't produce much at all. I just reached up and touched one to see. They don't burn me."

    If you are talking about LEDs... you aren't 'touching' the right ones.

    The ones that I am talking about consume 1-Watt (25 Lumens), 3-Watts (~60-Lumens), and up. These higher powered LEDs dissipate heat, and if not properly heatsinked - will self-destruct (like all solid-state devices will).

    If properly heatsinked though, theoretically, they'll last for up to 30 years without replacement.

    There are some higher powered LEd's on the horizon... one or two that I've looked at... and they're light output is up there at the 500 Lumens level - which is needed for adequate indoor lighting.

    I hate fluorescent bulbs. The light they cast is hard on the eyes and does nothing for the mood of a room. Perhaps these new bulbs are better, but after spending years at a desk under flourescents I can't bring myself to try them.

    I either buy pink incandescents or my favorite is halogens. Halogens are closest to sunlight and bring a room to life. I buy the low watts and keep them on dimmers. They do throw heat but to me its worth it.

    There is nothing more grim to me than those awful fluorescent tubes lighting a space. It has actually been found that they contribute to depression.

    Just my humble opinion.

    I use flood florescents in the inside can lights with good results. We use the replacement florescents in the table lamps all with good success.

    I found some outside flood florescent light bulbs at Sam's. They work good. I have them on motion sensors. Last night the deck lights came on and I looked out and there were three baby raccoons on the deck. They were standing up with their paws on the patio doors looking in the house.

    We live in the country and it's zoo time here. We have wild turkeys on our deck eating out of the bird feeder, we have a opossum who visits every night and a tame doe and her fawn eating wild mushrooms two feet from our deck.

    Hi LadyLee,

    Remember, saving energy prevents pollution. When you use less energy at home, you lessen greenhouse gas emissions in our atmosphere. Every CFL can prevent more than 450 pounds of emissions from a power plant over its lifetime.

    Unfortunately, these claims are sales propaganda ... there is some truth, but it is not as simple as claimed. The breakdown is somewhat like this:

    Coal provides 47% - dirty, but much better in recent decades with the new scrubbers - also emit alpha-radiation in significant quantities.
    Nuclear 20% - Do not emit any greenhouse gases or pollution of any kind.
    Natural Gas 17% - Emit extremely low amounts of greenhouse gas.
    Hydro-Electric 10% - Do not emit any greenhouse gases or pollution of any kind.
    Oil-fired 3% - Emits greenhouse gases, but are much more efficient than coal.
    Co-Gen (Trash burning), Wind, Solar 3% - Do not emit any greenhouse gases or pollution of any kind.

    How power plants work: When we turn off a bulb, or install a low energy efficient bulb, the power used does not cause the power plant to reduce power production. The plant produces a certain power level that is constant to meet load demand, plus a margin on the power grid for shifts in demand increases. Over time, a steady reduction in pwoer demand will impact power production. However, the power is more often simply shifted to other areas, regions, states, or even to Canada or Mexico where power demand is increasing. Depending on where we live, and the power source our home and city is using, turning down our lights or other power consumers has absolutely no impact on greenhouse gases. There is a 53% chance that our home may not be using coal or oil-fired sourced power.

    The good news: There is a growing shift to wind power, and the industry is gearing up to return to nuclear power plants. This is especially true as older coal plants are being retired. Also, various equipment, such as the more efficient lights you discussed, as well as appliances, etc. are all becoming far more efficient and consume less power. So, as we increase solar, wind and nuclear plants, we will see rapid reduction in coal use.

    Greenhouse issue: The earth and animals still emit far more greenhouse gases. Methane is far more destructive than hydrocarbons, so in smaller quantities, Methane can cause greater harm. The biggest producers of methane are cows, pigs, and humans. As we have more humans eating more beef and pork, these three animal groups will continue to pollute the earth with more and more methane. Decaying plants also will off-gas some methane, and we have a load of plant life on this earth. To start with, we need laws against farting outside, combined with indoor methane neutralizers. We need to figure out how to contain cow and pig mathane ... or eventually international treaties that ban beef and pork products. Turning to chickens will not help much, as chicken shit emissions are no better. I am serious, and am far more worried about this than the hydrocarbons from coal plants.

    Automobile hydrocarbons: This is a serious issue. We not only need independence from oil producing nations, we need to end oil as our base automobile fuel. I strongly favor hydrogen cells. Not only are they renewable forms of energy, but, only emit water vapor. This emission would be good for arid areas which could use the water. Water vapor would help cleanse the air, and improve humidity ratios.
