Compact Fluorescent Lamps (CFLs) – What you need to know about low energy lighting<\/p>\n
Introduction
\nCompact fluorescent lamps (CFLs) are smaller versions of the familiar fluorescent strip-lights
\nfound in schools, public buildings and many people’s kitchens. Like the strip-lights, they are about
\nfive times more efficient than tungsten incandescent lamps at turning electrical power into light.
\nThey also last many times longer and the saving in energy over their lifetime more than offsets
\ntheir extra cost. Governments all over the world are either encouraging or coercing us to replace
\nour tungsten lamps with CFLs to save energy and reduce our carbon footprint.
\nThe principle of operation is the same as a fluorescent strip-light. An electric current is driven
\nthrough a tube containing argon and a small amount of mercury vapour. This generates invisible
\nultra-violet light that excites a fluorescent coating (the phosphor) on the inside of the tube, which
\nthen emits longer-wavelength visible light.<\/p>\n
