Active cooling lighting
The quarter-size device next to this downlight is the active cooling system integrated into the luminaire. Hot air is pulled into the device, which inflates like a bellows then ejects the hot air. It requires electricity to run, but it's not expensive to make and will allow GE to use fewer LEDs for a given light fixture.
