Maybe begin from now swaddling bands of this generation of baby, don't know what 'bulb'.
The national development and reform commission requires on October 1, 2012 forced more than 100 w incandescent lamp production and sales, in 2013 began to gradually eliminated incandescent. Incandescent lamp once was very popular. This old man is respected, she replaced candles and oil lamps; She is a giant, we the late-starter technological innovations are all over her shoulder. Led supplier China once said.
She went away about three centuries. Our future generations should use technology innovation to create a more energy-efficient light source, that is what we comfort the old man.
The future maybe is no longer the same metal halide lamp, energy-saving lamps, LED lamps and lanterns we called energy-saving. There must be more energy conservation and environmental protection products. But keep in mind that our lamps and lanterns of every period of history, their achievement is indelible.
