LEDs  use only a tiny fraction of the energy needed by florescents and can last a decade or longer, but manufacturing complications require the use of sapphire, a rare and expensive material. Now research at the University of Cambridge promises a super-cheap alternative. Once that pesky little problem is solved, CFLs — and their inconveniently un-green mercury residues — will soon go the way of….incandescents.
