| CFLs or {{WP|compact fluorescent lights}} are a popular choice for [[energy-efficient]] lighting, and have the advantage that they can be used in regular light fittings.
| |
|
| |
| {{WP|Fluorescent lights}} with {{WP|Electrical ballast#Electronic 'ballasts'}} are slightly more efficient than other regular fluorescent lights and CFLs and give a more pleasant light.{{fact}}

| |
| {{WP|LED}} lighting is becoming increasingly attractive. It is used in remote regions such as Nepal, by the [http://lutw.org 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.

| ==Toxicity==
| |
| The mercury levels in fluorescent lights (including CFLs) are now usually considered to be within safe limits. However this is likely to vary widely between brands and models, and care should of course always be taken not to break them

|
| |
| ==Potential problems with fluorescents (including CFLs)==
| |
| Note that the quality of fluorescents can vary enormously
| |
| * light quality (spectrum)
| |
| * flickering,
| |
| * noise (whining)
| |
| * unpredictable life span (too sensitive to shocks, surges?{{sp))) particularly in some cheaper brands.{{fact}}
| |
|
| |
| ==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?{{sp}}
| |
| * Start a section on tri-phosphor lighting in the relevant Wikipedia and/or Appropedia article.){{sp}}
| |
| * Compare the life expectancy of different types of lights - find peer-reviewed studies, if possible. What factors affect life expectancy?{{sp}} (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. --[[User:Chriswaterguy|Chriswaterguy]] · <small>[[User talk:Chriswaterguy|talk]]</small> 19:19, 1 May 2007 (PDT))
