Several years ago, my wife and I made the decision to replace all of the light bulbs in our house with Compact Fluorescent bulbs. We had two principal reasons for doing so:
- Incandescent bulbs were burning out far too quickly due to “dirty power” at our house. I hated changing light bulbs constantly.
- We wanted to save money on our electric bill.
Several years ago, my wife and I made the decision to replace all of the light bulbs in our house with Compact Fluorescent bulbs. We had two principal reasons for doing so:
- Incandescent bulbs were burning out far too quickly due to “dirty power” at our house. I hated changing light bulbs constantly.
- We wanted to save money on our electric bill.
At the time, this was a fairly expensive decision, with bulbs going for about $5.00 each. We expected significant cost savings in electricity, and that initial $200 investment (or so) has continued to pay off for us over the years. Our electric bill — despite multiple computers and a laser printer — is about 20%-30% lower than that of similar households. And our kids forget to turn the light off ALL THE TIME!
(Ack! I’m turning into my father, walking around after my children and shutting off lights!)
In the past two years, Wal-Mart began a push to aggressively discount and market CF bulbs, much to the dismay of manufacturers who make far more money on old-fashioned tungsten bulbs (due to higher margins and shorter life) than on CF. This has driven the price down to around $1.00 each, and with an expected $36.00 savings per bulb over its lifetime compared to incandescent bulbs, this represents a much lower cost to homeowners today than the start of our experiment years ago.
In an effort to conserve electricity for its large and growing population, California — the third-largest economy in the world if it were its own country — is considering a bill which would outlaw further sales of traditional tungsten-based bulbs and mandate CF. In response to this legislation, GE has announced a newer, more energy-efficient tungsten bulb, which promises 1/2 the efficiency of CF today, and equal efficiency within the next few years.
Now, there are downsides to Compact Fluorescent. Chief among them is the fact that even though the light is a more pleasing shade than old-fashioned fluorescent, it’s still running at a base of 3600 cycles per minute. Literally, it’s flashing on and off 60 times per second, matching the frequency of the Alternating Current thrumming a constant rhythm throughout your whole city. Despite reassurances by manufacturers that new electronic ballasts cycle 30,000 times per second and eliminate the “flicker headaches” suffered by many people due to fluorescent lighting, my tachometer (a device to measure RPM, generally for propellers and rotors on my model aircraft) still sees a strong 3600RPM flicker even from CF bulbs.
Additionally, quality control in CF — particularly in the newer, cheaper Wal-Mart brands — is quite spotty. I’ve observed a steady degradation in the quality of bulbs as the price has dropped. With a new price point of only $0.50-$1.00 over competing tungsten bulbs, I’m finding newer CF bulbs aren’t lasting as long as their $5.00 ancestors. Many of them end up slow starting or burning out quickly. Of course, those more expensive bulbs are still on the shelf, but who’s buying?
CF bulbs also take a moment longer than incandescents to “turn on”. This is a minor nitpick; it’s a fraction of a second, but noticeable.
Lastly, CF bulbs do not handle cold weather nearly as well as tungsten bulbs. The bulb in my garage is quite dim in the winter, and much brighter in the summer.
So here’s the question: Who’s buying? Do you use compact fluorescents in your home, or do you stick with incandescent bulbs? Why or why not?
