DEFINATIONCarbon filament lamps are obsolete for general lighting , used for special applications.CARBON FIBER-An extremely strong, thin fibre , consisting of long, chainlike molecules of pure carbon that are made by charring synthetic fibers such as rayon in the absence of oxygen. Carbon fibers are used in high-strength composite materials in aircraft, automobiles, architectural structures, and in other applications where light materials capable of withstanding high stress are required .

A real odd one- this very unusual carbon filament lamp features a quite unique filament construction that I have never seen anywhere else before. It is a 220 volt bulb and as a result it needs a longer length of filament than 110-120 volt ones. Normally this is achieved by having 3 or 4 loops side by side often with anchor pins at the bottom of each to steady them.

ADVANTAGESCarbon filament bulbs and filament lighting add a unique effect to any room. It can be purchased in multiple shapes , wattage and colourIt fit most lamps and other lighting fixtures, as such fixtures have been built with incandescent light bulbs in mindIt has a good colour tone , pink light highlighting heavily the redder parts of the light spectrum.

disadvantagesthey are not very energy efficient. About ninety-percent of the energy that goes into the bulb is turned into heat rather than into light.they can cause fires if anything should lean against them inadvertently.its carbon filament evaporate quickly at high temperatures, which result in a short life for the light bulb.

types 15W Carbon-filament Flicker Bulb-This dramatic bulb rapidly 'flickers' for a candle-like effect, as its filament is moved by an internal magnet .This a large-sized bulb 70W Triple-loop Carbon Filament Bulb with higher lighting output. 40W Carbon-filament bulb -- provides light via its tall single-loop filament.

15w carbon filament flame-tip candelabra bulb , at 4-1/4in.tall,is right at home .40W Straight-sided Carbon-filament Bulb Create warm low-light ambiance .

usesUsed for heating purposes not for lightingUsed for decorative and ambiance settingUsed in line powered inspection lamps, on board ships, and on vibrating machinery. Used in underground for lighting signs and notices in tunnels.Used as low power radiant heaters for pets or livestock, and for general lighting when an old fashioned look is required.SPECIFICATION OF THE LAMPIt gives yellowish light . Its power consumption is high . Efficiency of the lamp is low i.e 2.5 to 4 lumen per watt.
