The Increasing Quality and Economy of LEDs

Excerpt:
" Compact fluorescents are the poster children for the energy efficiency movement. But in a not so far-away future, LEDs may give them a run for their money. We recently wrote about this in a recent, and surprisingly controversial, post.

LED bulbs are longer-lived and consume less energy than compact fluorescents, and they do not contain mercury. So why aren’t we using them already? There are two main complaints with LEDs: they are way too expensive, and they have an impractical spotlight type quality. But the University of Glasgow has a new process that they believe addresses both of these complaints."
