A unique mechanical design aspires to remove heat from this LED light bulb’s insides, but you still need to keep external ventilation in mind.

Liquid metal controlled by low voltage reversibly switches color and infrared response in nanoscale surfaces, enabling low power reflective displays, sensors, and optical security features.

In an effort to create simpler next-generation lighting solutions, researchers from the University of Turku in Finland have developed a color-tunable white OLED. It is a top light-emitting device that ...
