Dual cool jets
The cooling technology used in this LED bulb comes from GE's work on fluid dynamics for jet engines. GE researcher Mehmet Arik shows how synthetic jets pull in hot air at a certain speed but eject the heat more quickly. The net effect is a more effective heat sink than natural convection, which is important to maintaining the long life promised by LEDs.
