Bye bye bulbs
Thomas Alva Edison created the incandescent bulb in 1879.

09.09.2012 - However, the energy-gobbling lights have now had their day and as of September 1 it is illegal in Europe to manufacture them. Incandescent bulbs produce light by heating a tungsten filament with an electrical current and around 90 per cent of the energy used is turned into heat, not light. In a compact fluorescent lamp (CFL), however, fluorescent gas inside the bulb produces ultraviolet light when electrified, which the lamp's coating converts into visible light. It takes a CFL bulb only 15 watts to produce the same amount of light as a 60 watt incandescent bulb, so love them or loath them, you know the change makes sense.
