Incandescent bulbs have been in widespread use for as long as one can remember, without reaching the age of candles that is. Now, as the world becomes more aware of the environment, these low efficiency bulbs are on their way out; on an average, incandescent bulbs convert a mere 10% of the energy they use into light, the rest is heat. With the fate of these lamps sealed, options are being considered to take over the lighting empire of the incandescent lamp.
As of now, CFL lamps and LEDs are being looked upon as the new options. Current technology and associated costs aren’t really in favor of mass deployment of LEDs, and CFLs, though more affordable contain harmful chemicals. RTI International has announced a new contender in the shape of Nanofiber Lamps. These lamps are said to be much more efficient than incandescent lamps, and safer than CFLs.
These bulbs utilize a combination of nanofiber-based reflectors and photoluminescent nanofibers, as these fibers come in contact with electric current, they give out white light. The output is 55 lumens of light per watt consumed. The company says the device should be ready for the market in 3-5 years.
