Wikipedia : Compact Fluorescent LampsCompact fluorescent lamps use 60% - 70% less electricity to produce the same amount of light as their incandescent light bulb equivalent and have improved significantly in their brightness, light quality (incl. daylight spectrum designs), price and mercury content since the Ban The Bulb energy efficiency campaign was founded over 5 years ago.
Work is still needed to develop minimum standards for CFLs, improve domestic recycling services (see Recolight) and subsidise their purchase prices (as nPower did with Tesco in 2010 e.g. 20p for a high quality 20W CFL instead of £2.00).
Ban The Bulb recommends that you buy the best quality CFLs you can afford as these generally offer better performance and have the lowest environmental impacts.
The light produced by most CFLs is more visible to spectrometers than to human eyes so we recommend that you use lamps that are a slightly higher wattage than the packaging generally suggests.
The following Wikipedia entry for Compact Fluorescent Lamps is well worth reading if you would like to find out more.
A compact fluorescent lamp (CFL; also called compact fluorescent light, energy-saving light, and compact fluorescent tube) is a fluorescent lamp designed to replace an incandescent lamp; some types fit into light fixtures formerly used for incandescent lamps.
