Compact Fluorescent Lighting Overview

Compact Fluorescent Lighting is an easily overlooked energy saving technology. Compact Fluorescents have been around for well over a decade. Many people took a look at them when they were first introduced and quickly forgot about them as early models were quirky and expensive.

Compact Fluorescents have come down in price in recent years and many models are now shaped like traditional light bulbs, even giving off the familiar soft white light people have grown accustomed to. They are also far more long lasting and energy efficient than traditional incandescent light bulbs.

Compact Fluorescent Lighting Advantages

Compact Fluorescents have actually gained a market share of around 5% in recent years for a variety of reasons. They are very useful for hard to replace lighting, because compact fluorescents last much longer (up to 10 times longer) than traditional incandescent light bulbs. They offer significant energy efficiency advantages over incandescent lighting (around 4 times more efficient or 75% savings on electricity consumption), and thus save the consumer considerable amounts of money in electricity costs over the life of their operation. A house that is entirely switched over from incandescents to fluorescents could reasonably expect to cut their electric bill by one-third to one-half by using Compact Fluorescents, depending upon the usage of other electric appliances. That is a considerable amount of savings if an electric bill averages $100 to $150 per month.



  • Compact Fluorescent Lighting (CFL) Downsides (separate page at PESWiki) - While we applaud the trend toward more energy efficiencies, like anything else, compact fluorescent bulbs have a down side. This page is presented to document some of those, so an informed decision can be made, and by pointing out the problems, solutions might be produced/encouraged.

  • Do Fluorescent Bulbs Light the Way to the Future? - A compact fluorescent light bulb (CFL) is a tiny spiralled version of the long overhead lights in your office, that fits into the same fixtures as regular bulbs. The CFLs cost more, but use about one-third of the electricity of the incandescent bulbs. is a web site promoting CFLs. (NPR; Feb. 8, 2007)
