Cost-Saving Benefits of CFLs and Fluorescent Lamps

CFLs and fluorescent lamps save significant costs in electricity expenses, right? According to recent articles, many people are in doubt about this claim, and refuse to believe these bulbs are actually saving them money by using less energy. Furthermore, the higher initial cost of the bulbs is preventing many consumers from making the switch. However, tests have shown that CFLs can save households money even under the least ideal conditions.

CFLs and fluorescent lamps give off the same amount of light as their traditional incandescent counterparts, but they require considerably less electricity, which in turn reduces the damaging effects electric power generation causes to the environment. Incandescent light bulbs actually require four times the amount of energy to produce equivalent light in a fluorescent lamp. Fluorescent lamps are four to six times more efficient than incandescent lamps, reducing the power demand from local utilities. Because most power stations use coal as a source for electrical generation, they are large emitters of both greenhouse gas and mercury, which is naturally occurring in most coal that is used today.

Mercury: Why Is It Needed?

Mercury is an essential component of energy-efficient fluorescent lamps, allowing them to produce light and provide a longer life in comparison to incandescent bulbs. A typical fluorescent lamp is composed of a phosphor coated glass tube with electrodes located at either end. The tube contains mercury, of which only a very small amount is in vapor form. When a voltage is applied, the electrodes energize the mercury vapor, causing it to emit ultraviolet (UV) energy. The phosphor coating absorbs the UV energy, causing the phosphor to fluoresce and emit visible light.(1)

The amount of mercury required is very small, typically measured in milligrams, and varies by lamp type, year of manufacture, manufacturing plant and manufacturer. Although it is a necessary component, mercury from fluorescent lamps still poses significant health and environmental issues, and lamps should be properly stored, transported and recycled in a packaging configuration proven to effectively contain mercury vapor.
