GE Lighting (East Cleveland, OH) recently announced a light-emitting diode replacement for the 100-watt incandescent light bulb that packages 27 watts of input power in a standard “A-19” bulb shape. The GE Energy Smart® 27-watt LED bulb incorporates proprietary synthetic jet technology that was enabled by GE’s collaboration with ecomaginationSM Challenge winner Nuventix, creator of LED cooling technologies for energy-efficient lighting. LEDs are semiconductors that produce light. They must be cooled to ensure long life. In collaboration with GE, Nuventix developed a method for moving air to cool LEDs using an oscillating membrane, called a synthetic jet (an alternative to a fan), which fits within the envelope of the A-19 bulb shape.
GE testing confirms 100-watt incandescent replacement metrics: 1,600+ lumens, uniform omnidirectional light distribution, 3000K color temperature, 25,000-hour life rating (22.8 years at 3 hours per day), dimmable, no mercury, instant full brightness and 60+ lumens per watt—all fitting neatly in the standard A-19 bulb shape.
