“Glowing walls could kill off the light bulb”

Light-emitting wallpaper may begin to replace light bulbs from 2012 says The Carbon Trust (TCT):

A chemical coating on the walls will light up the room with an even glow which mimics sunlight and avoids the shadows and glare of normal light bulbs
A small, 3 to 5 volt, current will be needed to stimulate the chemical into action but the walls will be safe to touch
Dimmer switches will control brightness
TCT has awarded a grant of £454,000 to Lomox, a Welsh company which is developing the organic LED technology which will be 2.5 times more efficient than energy saving light bulbs
Lighting currently uses over 16% of all electricity use
The chemical coating can be applied to wallpaper or painted straight onto walls
It can also be used for flat-screen TVs, computers and mobile phone displays
The system could be powered by batteries or solar panels
