A MIT research has caught on like wild-fire in the industry this week, since it holds the potential of reviving the nearly phased-out incandescent bulbs. The research claims that by using nano optic crystal structures, they were able to raise incandescent luminous efficiency to 6% and holds the potential of reaching 40% rivaling LEDs. However, there was a slight glitch in the press release. The cited luminous efficiency data was a bit outdated, most likely traced to 2013 results.
