Compared to incandescent lightbulbs, LEDs produce a lot more lumens per watt of input power — they’re more efficient at producing light. Of course, that means that incandescent light bulbs are more ...

A new study led by MIT researchers could drive the development of more energy-efficient digital displays—such as flat-screen ...

Light Emitting Diodes (LEDs) are used in everything from household lighting and mobile phones to large display screens.

MIT Study Lights Way for Bright, Efficient Quantum Dot LED TV Screens ...

First used as status and indicator lamps, and more recently in under-shelf illumination, accent lighting, and directional marking applications, high-brightness LEDs have emerged within the last six ...

A simple resin coating dramatically extends the lifetime of blue quantum-dot LEDs, addressing a key barrier to brighter, more ...

LED bulbs are energy-efficient and designed to last for many years, but here are a few lesser-known features to consider when weighing a jump to LEDs. Martin LaMonica is a senior writer covering green ...

Just before Christmas, I took my kids to the Brooklyn Botanic Garden for an exhibition called “Lightscape.” Neon lights electrified trees and made the gardens glow. In one large field, hundreds of ...
