The three dollar LED bulb!

Home/Power/The three dollar LED bulb!

Researchers at Cambridge University have come up with a revolutionary LED design that uses low-cost gallium nitride grown on silicon. Before this, that particular man-made semiconductor could only be grown on sapphire wafers. What’s so revolutionary about it? 1. It uses just one fourth of the electricity conventional lighting does. 2. It costs a mere $3, due to the elimination of expensive sapphire wafers from the production process 3. It is completely mercury-free, leading to greatly reduced pollution levels 4. It lasts for 100,000 hours, which is many times what a conventional LED lamp delivers today. Its release in international markets is anticipated anytime now.
