Miracle bulb
COLUMBUS (Ohio). June 1. A new kind of light bulb developers say uses a fraction of the energy of traditionally varieties and can last up to 20 years makes its debut Monday, reports AP.
Hailed by some as the biggest Improvement since Thomas Edison Invented the light bulb In 1879, skeptics point to the sc-called E lamp s high cost and use of radio waves as potential draw backs
The lamps use a magnetic coil that generates a radio signal. which mixes with the same gas used In conventional florescent lamps. A plasma is formed, which makes a phosphorus coating on the Inside of the glass glow
The bulbs, which don't have filaments, can fit most sockets, generate up to 150 watts of power and last 10 to 20 years, developers said They are scheduled to be sold early next year for 10 to 20 dollar each
The Invention uses one-fourth of the energy of fncandcs cent bulbs because It pro duces less heat. It also Is billed as a money saver because consumes would have to buy fewer bulbs.
Lighting consumes one-fourth of all the electric power generated in the United States, Europe and Japan. E-lamp promoters said.
"We feel this can be as significant an invention as the CD or the fax machine or the cellular telephone was in the 198Os." said Pierre G. Vlllere. president of a co developer. Intersource Technologies
Observers In the energy Industry said the announce ment Is a significant one. but some expressed concern about the cost and the possibility that the bulbs could interfere with recep tlon of radio broadcasts.
American Electric Power Co. of Columbus, one of the coun try s largest investor-owned electric utilities, is invest ing dlrs 6.5 million in the technology.
"We believe ft will be a cornerstone of our energy conservation programs." said spokeswoman Marsha Ryan.
Intersource, started In 1989. said the bylb lasts from 15,000 hours to 20,000 hours. The 'typical incandescent bulb lasts from 750 to 1,500 hours.
Karl Johnson, manager of commercial building sys terns at the Electric Power Research Institute in Palo
Alto, Calif, said the E-Iamp is a major improvement if the developer's claims are true.
They re good steps to improve lighting efficiency." he said.
But he said paying 10 to 20 dollar for a bulb "tends to be a barrier," and said inventors have had problems in the past with the frequencies of the bulbs interfering with radios.
