A real alternative to incandescent light bulbs ?
Posted by Cedric in Coup de Coeur, Great Ideas, Our World
Is the Thomas Edison 1881 invention, one of the most successful invention of the 19th Century, will disappear soon due to its high consumption ?
Today the World starts to wake up and governments finally show some concern about our ever growing power consumption and all its side effects. This may indicate that time has come for the incandescent bulb to retire. It exists, for many years now, some economical lighting alternatives (fluorescent ) to the incandescent bulb but most of them were not really welcome into our living areas (living room, bed room, etc..) due to the livid bluer color and their acquisition cost.
Then the LED (light-emitting diode) finally jumped out of electronics equipments and started to invade the streets (traffic lights, flashlights, bicycle, etc..). They may replace soon all incandescent and halogen bulbs we still have at home. Brasil and Venezuela have started the phasing out of incandescent lightning and Australia wants to get totally rid of them by 2010.
During "LED EXPO and FPD KOREA 2007" MK Electronics presented its LED lighting 'Lumi-Forta' which can present more 512 colors via remote controller.
In comparison with other bulbs the LED, once its price will be reduce, have lots of advantages
