Worldwide, grid-based electric lighting consumes 19% of total global electricity production.^[1] The energy used to provide the world's light is 1 900 Mt of CO2 per year.^[1] In Africa 60% the energy for lighting and other needs is derived from wood, leading to deforestation.^[2] Combustion-based lighting is also a major cause of respiratory illness,^[3] and generally of poor quality for reading, contributing to illiteracy.^[4] All in all, plenty of reason to seek ways of providing more sustainable lighting everywhere. Certainly electric lighting will be a key part (in addition to Natural lighting).

CFLs or compact fluorescent lights^W are a popular choice for energy-efficient lighting, and have the advantage that they can be used in regular light fittings.

Fluorescent lights^W with Electrical ballast#Electronic 'ballasts'^W are slightly more efficient than older fluorescent lights and give a more pleasant light.Most CFLs now come with an electronic ballast ^[5]

LED lighting is becoming increasingly attractive. It is used in remote regions such as Nepal, by the Light Up the World Foundation as a healthier replacement for kerosene lighting. These lights are far sturdier than other types of lighting, especially compared to fluorescent lights.

LVD or Electromagnetic induction bulbs or the Electrodeless lamp^W These relatively new lamps offer dimmable, longer life and half the Watts per lumens than CFLs. ^[6] More information is needed on their performance ^{[verification needed]}

Suggested projects

Compare light quality of different lights. What is the flicker rate of CFL? Are there better quality ones, comparable to the high quality but expensive tri-phoshpor fluorescent lights with electronic ballasts?^{[expansion needed]}
Start a section on tri-phosphor lighting in the relevant Wikipedia and/or Appropedia article.)^{[expansion needed]}
Compare the life expectancy of different types of lights - find peer-reviewed studies, if possible. What factors affect life expectancy?^{[expansion needed]} (CFLs sometime don't last as long as expected in my experience, though I've been told by an efficient lighting expert that Phillips and Osram are more reliable than other brands. --Chriswaterguy · talk 19:19, 1 May 2007 (PDT))
