1.how much longer does an LED last than a conventional light sources?
Typically, an LED will last four times longer than a CFL and 25 times longer than an incandescent source that puts out the same amount of light.
2.why are LEDs considered more efficient than conventional light sources?
When comparing the lumen output between LEDs and conventional light sources, LEDs may have lower lumen value in many cases. However, LEDs are directional light sources, all the lumens emitted from an LED are directed towards the task area. Conversely, conventional sources emit light in all directions. The light is then modulated in a given direction with optical systems like reflectors and lenses. The amount of lumens that falls in the intended task area from an LED light source is greater than that of a conventional light source.
3.why are LEDs considered green technology?
LEDs are more efficient than most other light sources, so they usually consume less energy for a given task or at a spesific light output. Also, they do not contain hazardous materials such as toxic mercury. Moreover, LEDs have a longer lifespan and hence reduce the frequency of disposal of lamps.
4.how are LEDs beneficial in developing countries?
Many areas in developing countries use kerosene or bio-mass as fuel for lighting; these fuels degrade the environment and emit large amounts of CO2. LED technology provides light using minimal wattage that can be generated by micro power generators like solar panels and hydroelectric systems.
