A group of researchers from the University Wake Forest -Carolina del Norte, led by Dr. David Carroll Is working on a new type of plastic bulb from "Induced polymer electroluminescent technology" (FIPEL, Field-Induced Polymer Electroluminescent), Whose main attraction is that it emits a light with a temperature similar to the sun.
This solution is not only more efficient than current fluorescents, but also does not heat, contain mercury and does not suffer from flickering or buzzing or breaking as glass. Their lamps generate a light that does not have a bluish coloration, can be manufactured in any shape and color, and do not contaminate when breaking, such as compact fluorescent bulbs (CFL).
According to its creators are at least twice as efficient as fluorescent tubes (More or less the same as the current LEDs).
