Save energy, Save money
Over the course of the past year, I have been gradually replacing my incandescent light bulbs with the energy efficient compact fluorescents, or CFLs. To keep the initial cost down, I decided to install a CFL when any incandescent went out. However, I came to realize that I was actually spending more money by keeping the energy guzzling incandescents installed. A single CFL uses 75% less energy for the same amount of light, or lumen, over the lifetime of the bulb and lasts as long as 10 incandescents. Sounds like sound financial advice to me!
CFLs have been getting more and more space on the shelves at retail stores in recent years. The price has finally come down to about $2 or $2.25 a bulb (sometimes less when discounted). The technology has gotten better over the years as the flickering is no longer an issue and they now come in multiple sizes (and colors) to fit just about any light fixture you have in the house.
I have nearly completed replacing every incandescent bulb in my house – a total of 43 bulbs so far. All I have left is to purchase 10 of the dimmable CFLs for my ceiling fixture in the dining room which will run me about $60 at Home Depot for the specialty bulbs. There are 2 more bulbs in the basement that I have not yet replaced because I haven’t seen the size in a CFL. I never use that room, so I am not going to waste my time on it until we decide to remodel the room.
How do I know what kind of bulb to buy?
Anyone who has been raised in the United States will know that a 60 watt bulb gives off less light than a 100 watt bulb. We know intuitively what bulb wattage we need for what purpose in the home – it’s almost instinct. The introduction of CFLs is causing us to change out terminology and relearn our home lighting needs. The CFL equivalent to a 60 watt bulb is not a 60 watt CFL – it is a 13 watt CFL. It gives off the same amount of light, but at a much lower wattage. Another example is a 100 watt incandescent that is replaced by a 23 watt CFL.
When looking at the amount of light a bulb gives off, it is no longer practical to talk about wattage. The term that gives you a more accurate picture is lumens. See the chart below to compare some of the bulbs I have installed in my home.

While the most common light bulbs area readily available at reasonable prices, there are a lot of specialty bulbs that have a higher price tag. It took a while for me to find a “candle” type of bulb that would fit into a ceiling chandelier. A pack of 2 cost about $10.00 at Lowe’s. It appears that the local utility company, Ameren, has partnered with retailers like Home Depot and Sam’s club to offer discounted pricing on energy efficient lighting and I think I can get the candle bulbs for about half of that price. If so, I will be able to nearly complete my conversion. For more details on Ameren’s Act On Energy program, click here.
Are CFLs dangerous?
They can be. Any flourescent light bulb including the CFLs contain a small amount of mercury which can be a particular hazard to young children and pregnant women. The EPA recommends that in the case of a breakage that the area be evacuated for 15 minutes and then cleanup up promptly. Check out their recommendations here. While I am not exactly thrilled that there is a possibility of a small hazard in the house, I am hopeful that this is a short term risk as LED lighting seems to be a just a few years away from breaking into a wider market of common bulbs at affordable prices. Here’s hoping.
For the same reasons, CFLs must be recycled once they have finally kicked the bucket. The waste basket it no placed for a CFL because the mercury content will eventually get released into the landfill and into nature.
