New light.

Invented by David Carroll, professor of physics at Wake Forest University:

He says the new plastic lighting source can be made into any shape, and it produces a better quality of light than compact fluorescent bulbs which have become very popular in recent years.

"They have a bluish, harsh tint to them," he told BBC News, "it is not really accommodating to the human eye; people complain of headaches and the reason is the spectral content of that light doesn't match the Sun - our device can match the solar spectrum perfectly. I'm saying we are brighter than one of these curly cube bulbs and I can give you any tint to that white light that you want."

Curly cube? I'm guessing the BBC didn't hear that right and they don't say curlicue in Britain.
