DIY - Lighting, Incandescent or Fluorescent
For many years the pros and cons of incandescent versus fluorescent lights have been described. With the addition of CFL (Compact Fluorescent Lights), LED and other technologies the debate has shifted somewhat. But, first, some elementary science…
Incandescent bulbs acquired the name because what they do is, in essence, burn (i.e. incandesce, or glow with heat). A thin tungsten filament sits inside a partial vacuum. Electricity passes through the wire and, because it offers resistance to the flow of electrons, it heats up. Quickly, the temperature rises enough to make the metal glow.
The interior of the incandescent bulb is usually coated with a diffusing material to cut down on the bright glare of a clear, glass bulb. Though, of course, there are many clear glass lightbulbs around. That doesn’t alter the basic way the bulb operates, but it does change the look.
That look is chiefly the result of the lightbulb’s ability to closely emulate the wavelengths of light given off by the sun. That’s determined to a large degree by the temperature of its surface, about 6,000 Kelvin. That’s roughly equal to 5,700 Celsius, since K = C + 273. That’s about 10,300F. That similarity is measured by something called color temperature.
Interior bulbs will often be a bit lower in color temperature, more toward the bluish than the yellow of sunlight. But don’t confuse the color temperature with the actual temperature. Incandescent bulbs typically glow at anywhere from 120F-200F (49C-93C) or higher. Water boils at 220F or 100C, so that gives you an idea how hot one can be.
By contrast, a fluorescent bulb is much cooler because it generates light in an entirely different way.
Inside the fluorescent bulb are electrodes and a thin vapor, usually mercury and a few trace gases. A voltage is applied to one of the electrodes at one end in a long tube and electrons are shot out toward the other end, bumping into the mercury atoms along the way. When they do, they give energy to its electrons. When the mercury atoms release that energy again, it appears in the form of light.
That process generates much less waste energy in the form of heat. That provides the primary reason that fluorescent bulbs are so much more efficient. In other words they can produce about the same amount of light (measured in lumens) for the same energy put into them because so much less is wasted in the form of heat.
Remember that incandescent bulbs glow because the filament is white hot. That produces a lot of heat for the amount of light given off. The result to you, the consumer, is you’re paying for a great deal more electricity over the long run to heat a wire in the case of incandescents.
On the other hand, fluorescents don’t produce the same color temperature or spectrum as incandescents. Modern CFLs come close, but they still don’t have quite the same look as an ‘ordinary’ light bulb. As a result, fluorescents have, for decades, been reserved for areas where that look isn’t regarded as so important, such as the garage.
Still, the initial cost of a fluorescent bulb is 3-10 times a standard 75 or 100-watt bulb. So, the trade off becomes electricity cost savings over the lifetime of the bulb (about 6,000-15,000 hours for fluorescent, 750-1,000 hours for incandescents) versus up front investment costs. Over their lifetime, a fluorescent saves an average of about 70% on the total cost, including purchase price and electricity bill.
While recent discussion about the environment has entered the debate, in fact the contribution of light bulbs is so small it’s hardly worth mentioning. Much larger factors, such as industrial gases, auto exhaust and other outputs are many thousands of times larger than the total produced by home lighting.
So, the old pros and cons still apply. At least, they did until LEDs entered the picture… But that’s another topic.
