You can find them mostly anywhere today, they are highly efficient, give off a pleasant white light and, for some strange reasons, people always call them neon lights. Fluorescent lamps produce light by discharging an electrical current inside a mass of gas which becomes excited and starts emitting photon particles o... |

Light emitting diodes, or LEDs, are amongst the most efficient light sources ever developed. In terms of energy efficiency, light emitting diodes are capable of producing the optical output of an incandescent light bulb, by consuming one hundred times less energy. The problem is that LEDs can't compete with inca... |

It's not big deal when a light bulb breaks. Albeit while talking about tubular fluorescent light bulbs, things can take a very serious turn, mostly because these types of light sources contain small amounts of mercury. If the glass tube is broken, then the mercury can contaminate the environment, not a very good... |

In 1879, Thomas Alva Edison invented the first electric light bulb using a carbon filament, only to receive the patent for his invention two months later. In was the greatest invention of the 19th century, but although the materials used to construct the light bulb changed slightly over the years, its design remained... |

Since its invention more than 125 years ago, the light bulb has suffered relatively small changes in its design. It is probably the most inefficient device ever developed, since more than 90 to 95 percent of the energy it consumes during operation is spent on useless heat radiating from the tungsten filament, and onl... |
