MIT: Incandescents Now More Efficient than LEDs

The 110 Year-Old Light Bulb That's Never Been Turned Off
Researchers at the MIT are publicizing that they have fixed the incandescent lightbulb with a brilliant improvement. They have wrapped the interior filament in a crystal glass that both bounces light and contains heat. It recycles energy in a way that addresses the main complaint against Edison’s bulb: It burns far too much energy for the light that it produces.

Why is this interesting? About a decade ago, governments around the world developed a fetish for banning incandescents (through an efficiency rule) and replacing them with expensive LED technology and florescent bulbs. It happened in Europe first but eventually came to the United States. The last American factory to produce them closed in 2010, and they are ever harder to find in even the big-box hardware stores. (As with all such bans, there are exceptions for elites who desire specialty bulbs.)

The change has been seriously annoying for many consumers. It has even given rise to hoarding and...
