After 130 years of incandescent light bulbs, the era of incandescent bulbs was ended with an EU-wide ban. The light bulbs brought to the mainstream markets by American inventor Thomas Edison were regarded as a symbol of progress and modern comfort that have delighted generations with their pleasant warm white light. Incandescent light fixtures are available in numerous shapes and with different degrees of brightness (power consumption). The E14 and E27 socketed lights can also accommodate halogen lamps, energy saving lamps and LED lamps.
Incandescent lights are thermal radiators: Simply put, light is produced by heating tungsten wire until it produces light. The EU has prohibited the sale of incandescent bulbs for normal household use because these inefficient heat radiators convert only 5% of the absorbed energy into light. Many consumers lament over the "good ol' light bulbs", although modern light sources such as LEDs are much more efficient. Although no newly produced incandescent bulbs may be sold in the EU, however existing stocks will probably cover a few decades, even in the most popular E27 incandescent lights.
The classic light bulb has an E27 socket. They are available with both matte and clear glass, with the latter being much brighter. The name light bulb is derived from the typical pear-shaped glass, but this name is commonly referred to all kinds of lights, even LEDs. The more watts a light bulb receives, the stronger the light output and hence, a brighter room. E14 incandescent light bulbs, are also particularly widespread, which are known for being incandescent candles, or just "candles". Incandescent bulbs radiate light equally in all directions, which is perceived by many people as a very pleasant light. In addition, there are also reflector bulbs, in which the light is bundled together for providing a targeted light in a certain direction.
For all current types of incandescent lights, there are energy-saving replacements, whether it is for a floor lamp, table lamps, or other fixtures. Halogen lights are a longer lasting, more efficient improvement over the incandescent light bulb, where up to one-third of the energy costs can be saved. The halogen's longevity is achieved through a chemical reaction of the halogen elements with the tungsten filament, resulting in the redepositing of tungsten back onto the filament. Also, standard versions of LED light bulbs can be used with incandescent light fixtures, provided they have the right socket, called a "Retrofit" socket. Specially designated energy-saving lamps are mostly compact Fluorescent light bulbs, which produce their light by discharging gas and serve as a common alternative to the traditional incandescent lamp.
