Compact fluorescent lights (CFLs) are one of the best energy-saving upgrades you can make to your home. In terms of energy savings, a CFL uses only about one-fourth as much electricity as a comparable incandescent light bulb, while lasting 10 time as long. Replacing a standard light bulb with a CFL will pay for itself within about 6 months in reduced electricity cost alone, and over its useful lifetime a CFL will return about 10 times its cost in savings. I don’t have many 10-bagger investments, so this simple, energy-saving investment is one of the best ways I know of to get an almost risk-free, high return. But like any light bulb, CFLs can break. They contain a small amount of mercury, so some special precautions are in order when cleaning up a broken compact fluorescent light bulb. Here is what the EPA recommends.
