Interesting Facts about CFLs

Filed under Technology

Compact fluorescent lamps (CFLs) have grown ever-increasingly popular these days. Replacing incandescent lamps with CFLs is a means of reducing energy consumption. The reduction in the generation of greenhouse gases that contribute to global warming is also a prime reason consumers are making the switch. Below are some lesser-known facts about CFLs.

Fact 1: CFLs are known as lamps instead of what is commonly referred to as bulbs. A lamp is any device used for giving light; especially one that has a covering or is contained within something.

Fact 2: Manufacturers are able to make a CFL that resembles an incandescent lamp; a method of enfolding the coiled tube in a glass or plastic external casing, obtains the same appearance.

Fact 3: However, even the greatest CFLs may not make surroundings look exactly the same as with an incandescent lamp. This problem, in the majority of cases, is easily remedied. CFLs are sold in numerous colors and can cause the color of skin, and surroundings, to appear poorly. Check the color temperature of the CFLs; if they are not 2700K or 3000K, purchase those and see if that doesn’t correct the problem.

Fact 4: The majority of CFLs are not compatible with dimmers whose primary use if for
incandescent lamps. Labels will be on these particular CFLs stating a specific warning.

Fact 5: CFLs contain mercury which is classified as a hazardous material by the US Environmental Protection Agency and should be recycled instead of thrown out with the normal trash.

Fact 6: Many lamp fixtures have tags that warn not to utilize lamps greater than 60 watts. You do have the option of using a CFL that says it is the equivalent to a 100-watt lamp.

Fact 7: The lifespan of CFLs can be reduced if they are used at temperatures that are higher than normal.

Fact 8: CFLs use a considerable amount of less energy; over 50 percent less than incandescent bulbs, which means CFLs need a lesser amount of wattage to create the same amount of
light.

Fact 9: A broken CFL bulb can expose a person to mercury vapor and a small amount of solid mercury powder can also be released. Extra caution should be taken when cleaning up a broken CFL.

Fact 10: Manufacturers use factious names like “natural” or “soft white”. Temperature of the lamps, known as Correlated Color Temperature, actually determine the color hue.
