Moreover, it is at least twice as efficient as CFLs (which are filled with hazardous materials that can leak into the environment if the bulb is broken--FIPELs are not) and roughly on par with LEDs, both of which emit light that is not quite suited to the human eye. And the FIPEL technology is tunable--it can be manufactured to give off the soft, white light human eyes prefer or to emit any other color, making it potentially useful for billboard lighting and other displays. Its form factor is even customizable--it can be molded into bulbs with Edison connections to fit existing fixtures, but also into large sheets or panels that could fit into ceiling tiles or wall spaces to provide lighting that is unobtrusively embedded in the spaces around us.
