"Though we call them light bulbs, traditional incandescent bulbs are actually small heaters that give off a little bit of light--something you know if you've ever touched a bulb that's been on for a while. These bulbs were technological wonders when they were patented in 1880, but today they are inefficient dinosaurs. They waste energy and money, and they are responsible for millions of tons of global warming pollution."Although slightly more costly than incandescent lightbulbs, CFL's will very quickly pay for themselves. They are exactly what their name implies, a compact fluorescent bulb. They can emit nearly the same amount of light that an incandescent bulb could, but uses much less energy doing so.
A CFL bulb rated for 15 watts uses the nearly the same amount of energy of an incandescent bulb using nearly 60 watts of energy. You can see, just by that comparison, what the difference in energy use really is.
Example: Say you have 10 75 Watt incandescent bulbs at use in your home at a given time and are generally on for an average of 8 hours per day. The incandescent lights will cost you $329 to run per year. Switching the 10 bulbs to CFL's will cost you around $79. A drastic difference in price.
Pros of CFL bulbs:
- Incredible reduction in energy costs.
- Less heat emitted from the bulb (less wasted energy).
- They last much longer than incandescent bulbs.
- Less of a fire hazard.
Cons of CFL bulbs:
- Contains levels of Mercury and cannot be disposed of in a normal way. (Mercury levels should not deter one from purchasing CFL bulbs. The level is Mercury is far from exceedingly dangerous. The only way one would come in contact with the Mercury is if the bulb were to shatter.)
- Doesn't immediately have full powered lighting. Takes a few seconds/minutes for the bulb to warm up/ reach its full brightness.
- Not all CFL bulbs are capable of being dimmed with a dimmer switch. This is unfortunate because even more energy can be saved if the luminescence were to be changed.
