Lighting--from candles to LEDs

Curtis, Neil

Future Times;2012, Vol. 1, p5
The article discusses the developments in lighting technology. The incandescent lighting became the most common form of lighting, but it is inefficient, according to the author as only about 10 percent of consumed energy is converted into useful light. The fluorescent lamp produces approximately 100 lumens per Watt, using 75 percent less power compared to an incandescent lamp. The author shares that the adoption of light emitting diodes (LEDs) could reduce consumption of electricity.
